SUMMARY
The title for this report is “
Self-perceived health effect of hatha yoga”, and the researchquestion is “
What self-perceived health effects can we register from a 7-week hatha yogacourse in a healthy Norwegian population using a standard questionnaire measuring
quantitative and qualitative data?”
In this study 80 healthy Norwegians mean age 30.4 years (SD = 9.9) were asked 13 questions
about self-perceived health effects of a seven weeks yoga course. The question form is
inspired by e.g. Short Form 36 Health Survey Questionnaire (Ware & Sherbourne 1992) and
similar existing self-reporting sheets, but was adjusted to the subjects most interesting for this
particular study. The questions are mainly related to many of the common topics we meet in
physiotherapy practice like musculoskeletal problems and pain, and also problem related to
stress and psychosomatics. The results indicated a positive effect on all the questions asked.
Regarding musculoskeletal problems there were shown positive effect on the following; legs,
hips, lower-back/back, shoulders, neck and head (tension headache). The strongest effects
were found for stress reduction and for better mood.
The present study supports a large amount of previous scientific studies that have shown
similar positive results of yoga for a broad range of health problems. Maybe the most
interesting finding in this study is the positive results regarding stress reduction and
improvement of mood. Since stress and depression are among the largest public health
problems in the western world today there is a great need for effective interventions for these
client groups (Merson et al. 2006). Based on today’s evidence, yoga is considered to be a
promising intervention for clients with these kinds of problems (IAYT 2010). Findings from
literature suggest that the active ingredients in yoga might be the effect of physical activity,
respiratory exercises and elements from the yoga philosophy that seams to achieve selfefficacy
and self-realisation. To obtain stronger empirical data it would have been interesting
to have done the 7-week yoga intervention in a randomised controlled study, and also with
objective measuring parameters, and not only self-perceived health effects.

1. INTRODUCTION
1.1 Background for research questions
Life style as cause for non-communicable diseases – Physical activity & Stress
Physical inactivity, is an independent risk factor for chronic diseases, and overall is estimated
to cause 1.9 million deaths globally (WHO 2010). As a response to this there is an increased
emphasis globally on physical activity as a heath effector. This is also one of my reasons for
putting focus on yoga as an intervention related to physical activity.
Beside physical inactivity, many of today’s most common non-communicable diseases and ill
health are due to stress or distress, which means that people have more challenges in their life
than they have resources (Aldwin 2007). When this condition becomes chronic, and there is
lack of restitution, it may give several health problems (Greeson 2009). Musculoskeletal
problems are also often correlated to a stressful modern life style with monotonous work and
limited physical activity (Brudevold 2008). Musculoskeletal problems are right in the core
domain of physiotherapy, and among the major challenges in public health. As an example: in
Norway approx 50% of long term sick leaves and 33% of new disability pensions are based
musculoskeletal diagnoses (Wærsted 2008).
An historical overview shows that hatha yoga has been considered as a way to improve health
in a holistic aspect for more than 2000 years. But as for other traditional forms of medicine
from the same period e.g. tai-chi, acupuncture and various massage techniques, these early
interventions had no evidence-based reports or controlled studies, only the evidence based on
experience and observation. Today hatha yoga is not mainly considered as “medicine” in the
western world, but never the less widely used as intervention in complementary and
alternative medicine. Furthermore, a large number of scientific studies where yoga has been
used as the method of intervention for health improvement have been published in the last
decades (NCCAM 2009). A review of scientific research on yoga and health effects (e.g.
Lipton 2008; Lundgren et al. 2008; NCCAM 2009; Oken et al. 2006; Raub 2002; Williams et
al. 2005; Yang 2007) suggests that yoga might have effect on several issues correlated to life

style, stress and non-communicable diseases. It also seems like the interest for this kind of
intervention studies are rapidly increasing (Ross & Thomas 2010). One of the main reasons
for doing an effect study on yoga is that previous studies are indicating good effect regarding
non-communicable diseases and health issues related to stress, and hence would it also be of
both public health interest and of national economy interest to know more about this (Granath
et al. 2006). Modern scientifically studies from psychology, psychosomatics, physiology
medicine and physiotherapy may help illuminate the “active ingredient” in yoga.
1.2 Research question
What self-perceived health effects can we register from a 7-week hatha yoga course in a
healthy Norwegian population using a standard questionnaire measuring quantitative and
qualitative data?
1.3 Background and Aim of study
The background for writing this report regarding health effect of hatha yoga started out with a
personal experience and a curiosity to learn and understand more about this topic. Being a
physiotherapy student I started to reflect on how hatha yoga might have a positive effect on
general health problems and non-communicable diseases like musculoskeletal and
psychosomatic issues as reported from science? (NCCAM 2009).
The purpose of my study is to see if I can find some of the same positive health effects gained
from hatha yoga in a Norwegian population as earlier reported in numerous international
scientific publications (Ibid). Furthermore, I’m also discussing what might be the active
ingredient(s) in hatha yoga, and for which health problems yoga has the best effect. Since this
is a report related to physiotherapy I especially wanted to look at hatha yoga from a
physiotherapy perspective. E.g. find out if hatha yoga is supported by evidence based science
in such way that we as physiotherapists can give advise regarding hatha yoga as an suitable
intervention regarding life style health issues and non-communicable diseases. Can we also
find evidence showing that hatha yoga is compatible and in harmony with modern
physiotherapy theory and clinical practice?

1.4 Definitions
Yoga
– A Sanskrit word which means “to unite” or “union”, and is one of the orthodox lifephilosophies from ancient India.
Hatha Yoga
– This is the form of yoga that is best known outside India and is typicallyassociated with exercise containing the physical postures (
asanas) and dynamic sequences(
vinyasas).MBSR
– Mindfunlness Based Stress Reduction is a modern holistic intervention using manyof the ideas from hatha yoga and eastern philosophies. MBSR is showing well-documented
effect by a large amount of scientific studies on non-communicable diseases.
Non-communicable diseases
– Health problems / diseases often correlated to life-style, stress,genetics or environment.
1.5 Topics and hypothesis
Central overall topic in this report will be to discuss the empirical data from a 7-week course
in hatha yoga. I’m also using results obtained from this study to compare with data from
previous scientific studies. Information from previous scientific studies is also used to discuss
what might be the active ingredients in hatha yoga. Furthermore, I’m discussing the research
method where I’m emphasizing the questionnaire and study design. On the individual level
I’m looking at personal aspects of physical activity, experience of mind-body, health through
movement and self-perception of health. On the more therapeutically level I will highlight
hatha yoga as a health promoting intervention. Treatment philosophy will also be discussed
with respect to similarities between physiotherapy and yoga.
My hypothesis is that hatha yoga has the benefits we can get from physical activity, breathing
exercises and from the yoga philosophy included mindfulness meditation. I will argue for this
statement because these elements are so closely joined together in the yoga practice that they
function as one unity.

2. THEORY
In the following I will first introduce the historical background and philosophy of yoga.
Second, I will go on to describe three fundamental issues addressed in this report, namely
“health”, “health effect”, physiotherapy and the role of the physiotherapist. Third, I will
compare yoga to physiotherapy and search for similarities.
2.1 Historical overview of yoga
The word yoga is originally a Sanskrit word and means, “join together”, “uniting” “union” or
“communion”. Union of body, mind and soul. Yoga has also been described as wisdom in
work or skilful living. The ultimate meaning of the word yoga is in Sanskrit: “chitta vritti
nirodha”. Literary this means to cease the waves in the mind. The yoga tradition comes from
the cultures around the Hindus River Valley – the ancient India (Iyengar 1979). The yoga
tradition in this area is estimated to be several thousands years old and consists of a wide
spectre of life philosophy guidelines where the most important one is the Yoga Sutras of
Patanjali (Ibid.). Outside India, the term
yoga is typically associated with Hatha Yoga and itsasanas (physical postures) and vinyasas (dynamic sequences), or as a form of exercise. Hatha
yoga has today developed into several different directions, but in general most brands of hatha
yoga remains the idea of unity. There is much emphasise on mindfulness, awareness and a
holistic philosophy in a yoga class, and this is always integrated to the postures and the flow
sequences (Lea 2009). These factors are mainly what make hatha yoga “yoga”, and not just
another form of sport activity.
Hatha Yoga, is also known as
hatha vidya or the «science of hatha» yoga. The wordHatha comes from combining the two Sanskrit terms «ha» meaning sun and «tha» meaning
moon (Feuerstein 1997). However, when the two components of the word are placed together,
«hatha» means «forceful», implying that powerful work must be done to purify the body. Yoga
means to join two things together, hence hatha yoga is meant to join together sun (masculine,
active) energy with the moon (feminine, receptive) energy, thus producing balance and
greater power in an individual. This is also an analogue known from the yin and yang
symbols of Chinese philosophy. Hatha represents opposing energies: hot and cold (fire and
water, similar concept as yin-yang), male and female, positive and negative. Hatha yoga
attempts to balance mind and body via physical postures, purification practices, controlled
breathing, and the calming of the mind through relaxation and meditation. Asanas teach poise,
balance and strength and are practised to improve the body’s physical health and clear the
mind. “
The true power of yoga is the process by which an individual enters into an authentic 7
Bachelor report 2010 – Jan Petter Engvig
relationship with the multidimensional aspects of one’s whole being”
(Stapleton & Stapleton2002). Hatha yoga is also easy to fit into modern training philosophy where there is focus
both on the exercise and restitution – catabolic and anabolic processes in the body (Østerås &
Stensdotter 2002).
The first know written comprehensive material on yoga philosophy is by Yogi Patanjali who
lived sometimes between 200 B.C and 200 A.D. In the 15
th-16th century we got the mostcomprehensive text of Hatha Yoga, the Hatha Yoga Pradipika, by Yogi Swatmarama. This
work is nonetheless derived from older Sanskrit texts on Yoga besides Yogi Swatmarama’s
own yogic experiences. Many of the concepts formulated by Pantanjali and Swatmarama are
still central for the yoga teaching. The core values of yoga philosophy are often referred to as
“The eight branches, or limbs, of yoga” (Iyengar 1979) and to fully understand the content of
yoga and the values it is build upon I will briefly introduce it in table 2.1.1.
Table 2.1.1 The eight limbs of yoga
1.
Yamas: (ethical restrains / moral behaviour) – non-violence, truthfulness, generosityetc.
2.
Niyamas: (healthy habits) – purity, contentment, self-study, devotion and simplicity.3. Asana: (physical postures) – a calm body position, lying, sitting, standing or moves
where the practitioner is resting and present in the Self – although the yogi moves, he
is still. What make an asana a “yoga posture / movement” is the whole intention,
mindfulness and awareness brought into the experience. Personal experience is the
goal – not to perform the asana “perfect”.
4.
Pranayama: (breathing exercises) life energy through respiration.5. Pratyahara: withdrawing the senses form an external focus (taught) to an internal
experience of pure sensation (somatic sensory, proprio sensory perceptions /
sensations).
6.
Dahrana: concentration.7.
Dhyana: meditation / contemplation.8.
Samadhi: (higher consciousness) the state of balanced knowing, oneness; the ultimateunion of individual self and the universal.
8
Bachelor report 2010 – Jan Petter Engvig
The eight branches of yoga are more precisely viewed as eight levels of progress, each level
providing benefits in and of it self and also laying the foundation for the higher levels. All
eight levels are interconnected (DeBarra 1983). Furthermore, these eight branches very
clearly shows that yoga practice has a deeper foundation than a regular sport activity. There
are reasons to believe that this mindful approach and holistic yoga philosophy are involved in
many of the stress reducing and well being effects of hatha yoga (Hoffman 2008; Lea 2009).
Furthermore, I will briefly mention that many ideas of modern psychology and life
counselling have taken up much of the philosophy from yoga. On example might be gestalt
therapy which is based upon field theory (Lewin 1943); an holistic theory which says that all
things are interrelated, phenomenology (Husserl 1913); believing that experience is the source
of all knowledge, and existensialism (Britannica 2010); which emphasise that the individual is
solely responsible for giving one’s own life meaning. The focus in gestalt is the experience of
mind-body in the “here and now” context. From this experience the client will have a more
clear awareness of the Self and in this way be able to cope with his life in the best way trough
empowerment and self-actualisation (Clarkson et al. 1993). Much of the same is to be said
about Psychosynthesis (Assagioli 1965) and Mindfulness Based Cognitive Therapy (Segal et
al. 2002). All the main philosophical fundaments we find in these well documented methods
is also to be found in yoga (Iyengar 1979). Therefore there are reasons to belive that these
factors may be considered as “active ingredients” regarding general psychological /
psychosomatic health effects from yoga. The final aim of yoga is self-realisation (Iyengar
2001).
Table 2.1.2 Health effect of yoga
A review of scientific research on yoga and health effects (e.g. Lipton 2008; Lundgren et al.
2008; NCCAM 2009; Oken et al. 2006; Raub 2002; Williams et al. 2005; Yang 2007)
suggests that hatha yoga might have effect on the following:
o
Improve mood and sense of well-beingo
Counteract stresso
Reduce heart rate and blood pressureo
Increase lung capacityo
Improve muscle relaxation and body composition9
Bachelor report 2010 – Jan Petter Engvig
o
Low back paino
Help with conditions such as anxiety, depression, and insomniao
Tension headacheo
Improve overall physical fitness, strength, and flexibilityo
Positively affect levels of certain hormoneso
Positive effect regarding MS and epilepsy2.2 What is health?
WHO (1948) has defined health by the following words:
“Health is a state of completephysical, mental and social well-being and not merely the absence of disease or infirmity”
.As described here we see that the term “health” contains several aspects of life, and these
parts are often interconnected with each other. This way of looking at health is often called
holistic, meaning that the individual as a part of social system cannot be determined or
explained by its component parts alone. Instead, the system as a whole determines in an
important way how the parts behave. It may be difficult to set common measurements, or an
objective numeric rating scale, for what is “good health” or “poor health”, because the
understanding of this is very much a subjective perception on the individual level. On the
other hand there are several tools for surveillance of health status in populations and
individual levels (Merson et al. 2006). As an example there exist standardized questionnaires
and from these kinds of investigations we can have a measure of self-perceived health, e.g.
the SF-36 Health Survey questionnaire (Ware & Shareborne 1992)
.2.3 What is health effect?
“Health effects (or health impacts) are changes in health resulting from exposure to a source.
Health effects are an important consideration in many areas, such as hygiene, pollution
studies, workplace safety, nutrition and health sciences in general”
(Wikipedia 2010). Ahealth effector or a determinant for health is the factors that may have positive (or negative)
influence on a person’s health status (Merson et al 2006). As for surveillance of health status,
there exist several standardized questionnaires for measure the effect. This might be effect
from different interventions, determinants or effectors. In my study I’m interested in a
measure that is giving the results as self-perceived health effect – how the individual
10
Bachelor report 2010 – Jan Petter Engvig
experiences the health effect in his or her mind-body in a subjective way. A typical example
would be the Patient Global Impression of Change, PGIC (Hurst & Bolton 2004).
2.4 What is physiotherapy?
The Norwegian Physiotherapy Association (NFF) has stated the following:
”The field ofknowledge for the physiotherapist are body, movement and function. The theoretical
fundament for the profession is based on natural science and social science, and a
recognition that there are several different factors contributing to the health status, and
furthermore also for pain and disability. In addition to injuries and illness, may also the life
situation and experiences, together with social and cultural conditions lead to afflictions and
functional disabilities, due to that both physical and psychological strain are likely to be
bodily incorporated. This means that the different parts of the body, body-person, bodysociety
are all interconnected.”
(NFF 2006). From the World Confederation of PhysicalTherapy (WCPT 2010) we know that movement enhancement and functional training are
among the core interventions used by physiotherapists both as treatment and for health
promoting. As emphasised by the profession’s title, “physical therapy”, physical activity is
essential in this professional field. The Norwegian Physiotherapy Association (NFF 2008) put
much focus on physical activity as a health effector, and is recommending the use of physical
activity both for health promoting purposes and as intervention in rehabilitation.
2.5 Physical activity
In Norway the Department of Health has given its guidelines regarding physical activity and
health promotion in several important documents e.g. “Recipe for a healthier Norway” (2002-
3) and “Handbook for Physical Activity” (2008). There is now a broad consensus that
physical activity is of great importance regarding health, both in a global public health
perspective (WHO 2010) and on the individual physiotherapist-client level (NFF 2008).
Furthermore, physical activity seams to have a positive effect on several aspects of health
such as musculoskeletal issues, cardio vascular disorders, diabetes type 2, weight control
regarding obesity, colon cancer, Alzheimer, psychological problems, psychosomatics, general
well-being and perception of life (Larson et al. 2006; Martinsen 2004; Merson et al. 2006;
NFF 2008; WHO 2010).
2.6 Stress
11
Bachelor report 2010 – Jan Petter Engvig
Beside physical inactivity, stress is a major contributor to non-communicable diseases in
public health (Larsen 2001). Stress or distress is a topic of great concern in heath care and is
often connected to psychosomatics. Stress may also be perceived as a problem in daily life for
many of us even if we are healthy. There are still some disagreement of the term “stress” –
should it rather be called “distress”, “strain” or something more medical term like “sustained
arousal”? (Wyller et al 2009). Stress may be psychological, physical or both. E.g. to many
activities on to many arenas at one time, physical overload, to many personal conflicts, lack of
control in life, perceived threats, anxiety and insecurity, and to little time to restore and
restitution. The susceptibility of stress is highly subjective, but is commonly increased when a
person experiences little control over the situation, when there is little predictability and little
sense of coherence (Antonovsky 1979; Brodal 2007). In yoga terminology “stress” could be
called imbalance in hatha, or in traditional Chinese philosophy; disharmony in yin and yang.
Stress is in medical terms defined as a condition of increased state of alarm on psychological,
physiological and behaviour levels (Jonsdottir & Ursin 2008). This condition triggers the
nevro-endocrine “fight-or-flight” response which include the Hypothalamus-Pituitary-
Andrenal (HPA)-axis, stress-hormones and physiological responses (Seyle 1936;1956;1982).
These responses are closely related to the autonomous nervous system with an increased
sympathicus activity and decreased parasympathicus activity (Brodal 2007). In short term the
physiological stress response is normal and beneficial in order to cope with a challenge. On
the other hand, when stress becomes chronic, and there is lack of restitution, it may give
several health problems (Greeson 2009; Larsen 2001; Selye 1982). What most scientists agree
upon is that “stress” over a long period of time may be a treat to your health (Brudevold
2008). Stress is also recognised by WHO as a determinant for health in a global perspective.
The problem is increasing in the western world and it is estimated that stress cost the EUcountries
approx. 20 mill Euros per year in health expenses (Knardahl 2007).
It’s a common problem related to stress that people get a reduced ability to relax, and
this may lead to both physical and mental symptoms (Brudevold 2008). Lack of ability to
relax may lead to muscular tensions, shortening of muscle fibres and reduced flexibility. But
because our body is a holistic system, one unit, our physical tensions may also lead to inner
disturbance of e.g. the digestive apparatus, respiration, circulation and muscular pain. Lack of
relaxation is also correlated with increased sympaticus activity in the autonomous system. On
the other hand, relaxation response will induce parasympaticus activity (Ibid). All these
factors above are interconnected. Therefore the ability to relax will be beneficial for the whole
human mind-body, and especially regarding stress reduction, anabolic processes and recovery
12
Bachelor report 2010 – Jan Petter Engvig
(Benson 1975). More about stress reduction and relaxation response related to yoga will be
discussed later in this report.
2.7 Respiration
Respiration is one of the keystones in yoga and it’s a part of my hypothesis that this is one of
the active ingredients regarding health effect of yoga. Therefore I think it’s useful to present
some theory regarding this. Respiration is also an issue of great concern in physiotherapy
because it’s so tightly linked to body posture, musculoskeletal issues, and physiological
processes in the body and also to psychological factors (Bunkan 2008). The diaphragm
muscle is the most important muscle during normal breathing and separates the abdominal
cavity from the thorax cavity. The diaphragm muscle is attached to the sternum bone in front,
along the lowest rib bones and back to the spine at level Th.10-12 (Netter 2003). One special
feature regarding the diaphragm is that it has double nerve innervations, which means that the
breath can be regulated both by the autonomous nervous system and by will. Consequently
we are able to do specific breathing exercises controlled by our own mind. According to Berit
Bunkan (2008) both muscular tension and psychological distress can lead to an unfavourable
way of breathing by the use of accessorial respiratory muscles and increased tension of the
diaphragm. This condition may lead to reduced circulation for blood and lymphatic fluid. It
can lead to poor conditions for the abdominal organs, and also for the hearth and lung. An
overextended way of breathing will also make it hard to let go of general muscular tension in
the body (Bunkan 2008). Regarding more musculoskeletal problems it is suggested that an
overextended and tensed diaphragm muscle can give rise to lower back pain because it’s
attached to the spine at Th. 10-12 level and also interconnected with the m. lumborum and m.
ilopsoas. Extensive respiration using the accessory muscles may also give musculoskeletal
problems in the neck and shoulder, for example “thoracic-outlet syndrome” (Caillet 1964),
and may irritate the Vagus nerve inducing problems for the organs innervated from this nerve
(Dahl & Rinvik 1999), neck pain and tension headache (Bunkan 2008). Inadequate respiration
patterns may also lead to unfavourable body posture and have influence on the balance (Ibid).
As listed here the respiratory function is closely interconnected with almost everything in the
body. Last but not least, the respiratory system is also strongly connected with emotions and
mind.
2.8 The role of the physiotherapist in the field of physical activity and stress reduction
13
Bachelor report 2010 – Jan Petter Engvig
From the Norwegian Physiotherapy Association we know that a professional physiotherapist
should be competent in leading organized physical training, and be able to give qualified
advices and coaching in this field (NFF 2008). From the Bachelor program in physiotherapy
we have also learned that knowledge about physical exercises is one of the main fundaments
in our education and an important intervention in treatment and health promoting (Fyrand
2002). Stress reduction techniques aiming to reduce sympaticus activity and the HPA-axis
are also well known in physiotherapy theory. Several methods are described e.g. by Berit
Bunkan (2008) and by Elise Thornquist (2003). On the basis of this the physiotherapist should
be able to give qualified, evidence-based, advises both regarding physical activity and stress
reduction. Since hatha yoga often is advertised as a method for physical activity and stress
reduction, and since there are currently over 430 million people training hatha yoga word
wide, it should also be natural for a physiotherapist to be able to give clients advices
regarding this topic (IMY 2010).
2.9 Behaviour change
From theory in public health we know that behaviour change on the individual level is of
great importance regarding life style illnesses (Nutbeam & Harris 2005). So with respect to
physical activity there is much we can do as physiotherapists to inform and motivate the client
regarding behaviour change, but we also know that the person himself must mobilise will and
trust himself in order to gain results. Our goal would be that the client himself would gain
empowerment and self-efficacy, so that he feels that he is in charge and have control over the
situation himself (Bandura 1997). As physiotherapists we can give advices about physical
activity such as yoga and inform about the evidence-based health benefits from this (NCCAM
2009). However, it will necessarily be up to the client himself to experience what this activity
means for him on a personal level. In a general point of view it’s essential to find an activity
that suits each and one of us, and that is meaningful to us. Regarding yoga there is substantial
evidence to say that this activity might have a philosophical content that will increase selfefficacy
and empowerment, maybe more than in an ordinary physical activity, and than again
induce a positive behaviour change. The reason for this statement is the fact that much of the
yoga philosophy is taken up by modern psychology and life coaching, and is supported by
scientific evidence to improve self-efficacy (Assagioli 1965; Clarkson et al. 1993; Iyengar
2005; Segal et al. 2002).
2.10 Are there similarities between physiotherapy and yoga philosophy?
14
Bachelor report 2010 – Jan Petter Engvig
There are substantial arguments for calling hatha yoga a kind of physical activity. In addition,
yoga includes breathing and mindfulness exercises, all with a holistic approach. Another
important factor is that yoga is a non-striving and non-competitive activity. The yoga
philosophy is also important. A mentor in Norwegian physiotherapy, Berit Bunkan, PhD, has
dedicated a chapter about yoga in one of her books. She writs the following:
“The principlesfor yoga can be recognized in many other good systems for physical exercise, also in physical
therapy”
(Bunkan 2008). Another physiotherapist and author, E. Thornquist (2003), alsowrites about yoga as a useful intervention in physiotherapy. Furthermore, prominent
physiotherapists such as Nina Schriver, PhD, senior researcher at University of Oslo, and
Professor Gunn Engelsrud, at Norwegian School for Sport Science, both emphasises the
positive value of yoga (Høiland 2010; UIO 2010). Gunn Engelsrud as a physiotherapist is
emphasizing the holistic view of the human and that the mind is one integrated part of the
body. The life is lived and experienced through our body and as individuals we are
interrelated to each other. Sensations and emotions are always present in our body and can
both be expressed and released trough movement (Høiland 2010). Many of these words are
the same as in the statement on “what is physiotherapy?” by the Norwegian Physiotherapy
Association (NFF 2008). In other words, this means that the physiotherapy approach should
be holistic. It is therefore also of great interest for the present study to know that these values
are shared by the yoga philosophy (Iyengar 2001). Consequently, it exist reasonable
arguments for saying that yoga easily could be a suitable intervention used in the field of
physiotherapy regarding health promotion. As an example “Medical Yoga” has now in
Sweden become a natural part of the public health services in combination with regular
physiotherapy at several hospitals and other health institutions (IMY 2005).
3. METHOD
3.1 Study design
This study is based upon 80 normal healthy volunteers, participating on a seven-week
classical hatha-yoga course. The participants were not send to this course from general
practitioner or other health personnel, but were there for personal reasons. Experienced yoga
teachers at a health and fitness center in Oslo, Domus Athletica, held the course. The study
had no control group and was not randomised. The participants were informed about the study
and the confidentiality handling of data before they chose to fill in the questionnaire or not.
15
Bachelor report 2010 – Jan Petter Engvig
The average age of the study population was 30.4 years (SD = 9.9 years). The population was
dominated of women containing 90 % and 10 % men. This roughly also represents the
distribution numbers in the total population practicing yoga in Norway and western countries.
The study’s data collection is based upon a questionnaire containing twelve standard
questions regarding health. The answers is reported on a numeric rating scale from 0 to 4: 0 =
zero effect, 1 = slightly positive effect, 2 = moderate positive effect, 3 = good positive effect
and 4 = very good positive effect. The reported numbers are meant for quantitative
measurement of the self-perceived health effect of yoga. The questionnaire form and content
was designed particularly for this study. It is inspired by the most widely used self reporting
forms regarding personal health, e.g. Short Form 36 Health Survey Questionnaire (SF-36),
Perceived Stress Scale (PSS), Patient Global Impression of Change (PGIC) and other short
form self reporting health questionnaires. In addition there was one open question for personal
comments on what the yoga has meant for each person in particular, question thirteen. This
question was included to obtain qualitative information. All questions are shown in
Appendix-I.
3.2 Intervention
The yoga course was held one time a week for seven weeks. Each session lasted 90 minutes
and consisted of classical hatha yoga. The yoga class had a regular structure that contains
typical issues put in order given by the yoga philosophy (Iyengar 1979).
Table 3.1 – Content of a 90 min yoga class
Table 3.1 shows the content of a typical 90 minute class of hatha yoga (Studentidretten 2010):
Introduction:
Approx. 10-15 min.
“Warming up” starting with approximately very easy yoga / sitting or
lying meditation / body scan / breathing exercises / easy dynamic
movements.
Main part:
Approx. 60-70 min.
Physical postures and dynamical postures (asanas). Dynamical
sequences often referred to as vinyasas or “flows”. Main focus here will
be muscle training for strength in basically all body parts, core muscles
and stability, flexibility, physical balance, coordination and to a certain
level also cardio vascular training e.g. with dynamic flow sequences
such as the “Sun Salutation”. In between the physical activity there will
16
Bachelor report 2010 – Jan Petter Engvig
often be short breathing spaces; meditative short breaks for selfobservation
and just feeling your body and breath relaxing. Furthermore
it is quite essential to emphasize the intention that is integrated in all the
yoga exercises; all exercises should be performed with full awareness of
the postures and movement, feeling your body and to be present with all
senses. The breath is also at most time included as a part of movements
and sequences. Hatha yoga is also often referred to as “meditation in
movement”. It is from these elements the holistic body-mind aspect of
yoga is most clearly, and it is here yoga differ most from other “sport
activities”. The goal is the personal experience of body and movement,
and than a stronger consciousness of the Self.
Calm down:
Approx. 10-15 min.
The yoga class would typically end similar to the way it started.
Typically, very gentle yoga containing guided meditation, supine
position body scan, breathing exercises.

4.5 –Personal comments (Question 13)
The personal comment reflects in many ways the results from the quantitative data as many of
the comments are regarding stress reduction, relaxation, life energy and better mood. On the
personal level it’s also clear that the yoga class this once a week has meant much for the
20
Bachelor report 2010 – Jan Petter Engvig
quality of life for many informants. Some of those who reported to be in very good shape
before the yoga and are doing much additional training, reports also the lowest score on the
quantitative results. For all personal comments, see Appendix II.
5. DISCUSSION
The results of this study suggest that there are several potential health benefits from hatha
yoga. Especially there was shown positive results for health indicators such as relaxation,
stress reduction and better mood. I will in this section discuss the method, the results from my
study, and try to explain what could be the active ingredients in hatha yoga. Furthermore, I
will also discuss if yoga practice is compatible with physiotherapy theory and western health
care of today.
5.1 Method discussion
Regarding the method I want to discuss the fact that this study has focus on self-perceived
health effects and not on objective measurements. It is the personal benefits experienced from
yoga; including mind-body in movements, breathing exercises and meditations I want to
illuminate. Since the study population consists of volunteers, and not everybody in the course
chose to fill in the questionnaire, there might be a different result if all participants had to
answer. Weakness in the study is that I have limited control of what physical activity other
than yoga the study population might do. However, one informant was excluded from the
study because she reported to attend two yoga classes each week instead of one. Furthermore
I don’t have any exactly measurements regarding health status for the start point. However,
information regarding musculoskeletal and headache issues before the course is reported in
the questionnaire. On the other hand, the focus in this study has been the self-perceived
change and the personal experience of health effect after the 7-week course. From a scientific
point of view it would have been of interest to have both empirical data from start-point and
end-point, and also data from objective tests. This might have been e.g. blood pressure and
heart rate-variability regarding stress, serum levels regarding stress hormone cortisol,
oxytocin level in serum regarding relaxation / well-being. On respiration we could have tested
e.g. lung vital capacity, peak expiratory flow. For muscle strength we could have used
standardised test for the main muscle groups. On the other hand, this is far beyond what’s
possible regarding time and resources for a student project. The strength in my study is that I
21
Bachelor report 2010 – Jan Petter Engvig
have bout a wide range of relevant questions and a quite large study population (N = 80). It is
also a strength that the research questions was design with several established questionnaires
in mind, and the scaling system was inspired from the Patient Global Impression of Change
and Numeric Rating Scale. To have such standardised systems as guidelines is an advantage
for making an adequate questionnaire. The reason for choosing a 7-week course is that this is
the standard length for all yoga courses at Domus Athletica. There are also reasons to believe
that such a long period of time is needed in order to register any significant effects. This 7-
week yoga course can also to some degree be compared with the 8-week MBRS program, a
well-established intervention method that is frequently used regarding non-communicable
diseases and health issues often related to stress and life style.
5.2 Results discussion
1 & 2 – Musculoskeletal issues
In this study 56 informants reported that they had some kind of musculoskeletal problems at
the starting point of the 7-week yoga course. All of these reported a positive effect of the
intervention and had an average score of 2.30 (SD = 0.71), indicating that they had a
moderate to good positive effect for their issues. Most of the reported problems were related
to back, neck and shoulder pain. We know from yoga theory about the different ansanas
(physical postures) and vinyasas (dynamic flows), that many of these are quite similar to
those used in typical physiotherapy sessions for back, neck and shoulder problems (Iyengar
1979; Kisner & Colby 2002). As examples for lower back pain the physiotherapist, after a
physical examination, will typically recommend exercises for motor control and strengthening
of core musculature for better stability (Hodges 2003). Similar exercises are also among the
most common asanas in traditional hatha yoga. It should therefore be logical that these asanas
might have a positive effect on musculoskeletal issues. Furthermore, there exist also several
scientific studies supporting the beneficial effect of yoga for issues like for example low back
pain (Hem 2006; Sherman et al. 2005; 2007; Williams et al. 2005; 2009). For a general
review on the psychophysiologic effect of hatha yoga on musculoskeletal function I refer to
Dr. James A. Raub’s article from 2002 (Raub 2002). My postulate will therefore be that the
active ingredients in yoga regarding musculoskeletal issues might be the asanas and vinyasas.
Other ingredients might be the respiratory exercises and relaxation techniques. Both these
factors are important regarding muscular tension and pain (Bunkan 2008). Nevertheless, from
a physiotherapy point of view, one should be critical to some of the yoga postures if the client
22
Bachelor report 2010 – Jan Petter Engvig
is suffering from severe back pain. If the client is new to yoga and not very flexible, some of
the asanas might be to extreme and do more harm than good. In such cases it would an
advantage if the yoga teacher also had good knowledge about physiotherapy. If not, the client
should receive some advices from a physiotherapist or a medical doctor before attending a
yoga class. However, it’s in the yoga philosophy not to push limits regarding pain, but always
listen to the body (Iyengar 1979).
3 – Flexibility
Of all 80 informants in my study 95 % reported that they had a positive effect regarding this
topic. The average score was 2.24 (SD = 1.0), indicating that the participants had a personal
experience of a moderate to good effect. Since much time is spent on stretching during the
yoga class, this result must be considered reasonable. 8.8 % of the study population reported
very good effect (score 4). In yoga flexibility is also considered to be of great importance, and
much emphasise is put on this issue. Hatha yoga includes hundreds of exercises for stretching
and flexibility (Iyengar 1979). There should be reasons to say that these exercises are the
active ingredients regarding the effect of increased flexibility. Flexibility will be a result of
joint mobility and muscle length and is one of the core elements physiotherapists will look for
in a physical examination (Fyrand et al. 2006).
From a physiotherapy point of view it’s considered that to have a flexible body is a
fundament for being able to do the normal movements for activities of daily living. Advises
regarding flexibility exercises should be an important issue in physiotherapy. There are also
reasons to look critically at some of the most extreme stretching asanas in yoga and know that
these are not advisable for beginners.
4 – Muscular strength
This issue showed the lowest score in the study. However, as many as 78.8 % of the test
population reported a positive effect and the average score was 1.36 (SD = 0.97). From sport
science theory we know that if we are going to gain good effect from strength training there
should be a minimum of two-three practices a week. For the best effect regarding maximum
dynamic muscular strength the energy level during training should be 80-100 % of max, 1-6
reps x 3 (Fyrand 2002). In the yoga intervention the persons had only one class each week.
Furthermore, since yoga techniques don’t use external weights there are only infrequently
sessions of 80-100 % maximum intensity in a beginner’s class of hatha yoga. I have reasons
to believe that these factors may contribute to the low score for this topic. On the other hand
23
Bachelor report 2010 – Jan Petter Engvig
the 1 RM value (one repetition of maximum, kg) would differ much from person to person,
and those who is not used to weight training before starting with yoga might experience many
of the asanas as 80-100 % of 1 RM. However, from the personal comments I noticed that they
who do much training besides yoga scores low on the muscle strength topic (e.g. informant
#31). Other forms of yoga, like Ashtanga or Power yoga, would probably give a better effect
regarding muscular strength since in these forms of yoga there is more focus on this issue.
Muscular strength is a topic of great concern in physiotherapy. We need a certain level of
muscular strength to be able to have a normal active life (Kendall et al. 2005).
Physiotherapists with knowledge in sport science and training theory should be well qualified
to give advices regarding how to increase muscular strength.
5 – Balance
In the present study 88.8 % of the informants reported positive effect regarding balance with
an average score of 1.74 (SD = 1.0). This result indicates that the effect was perceived as
close to moderate good. In a typically yoga session there are several balance exercises, and
there exist dozens of different asanas for this purpose. In yoga philosophy balance training is
also considered as an exercise for concentration and mental balance. However, as for the
result for muscular strength, the result regarding balance in this intervention showed only
moderate effect. This may be explained due to the fact that also balance training needs more
sessions a week to gain higher effect (Johannessen 2009). Balance or postural control is also
one of the keystones in physiotherapy. Postural control is of great importance for the
development of motor control for infants. For adults, especially for elderly people, postural
control is important in maintenance of function in daily activities. Research has also shown
that good postural control is positively correlated with better mental balance and vice verca
(Brodal et al. 2006). From a physiotherapy perspective, focus on balance training is advisable
for many aspect of quality of life.
6 – Relaxation
The question here was if the person experienced an increased bodily relaxation response,
ability to relax, from yoga. 97.5 % of all participants in this study reported that they had
experienced a positive effect regarding relaxation ability. The average score was 2.51 (SD =
0.94), meaning that they perceived the effect as moderate to good positive effect.
Furthermore, 10 % of the study population reported that they experienced very good effect
(score 4) regarding relaxation. The results indicate that regular yoga practice for 7-weeks
24
Bachelor report 2010 – Jan Petter Engvig
contribute to a self-perceived relaxation response. Since yoga practice have so much focus on
this topic the result in this study seems logical. Commonly for this 7-week course the class
would both start and end with relaxation response inducing sessions. As for other kinds of
training, the results often follow a dose-response correlation (Østerås & Stensdotter 2002). In
this intervention we had a relatively large dose of relaxation exercises and gained a response
that seems to be reasonable according to this. From physiotherapy theory we also have similar
approaches for inducing a relaxation response. As an example we can use postures that gives
wide support and grounding, and that improve basal respiration, relaxation techniques, and
different respiratory exercises as described by e.g. Bunkan (2008) and Thornquist (2003). In
physiotherapy relaxation inducing exercises might be recommended e.g. regarding
psychosomatics, muscular tensions, fatigue and also for asthma (Ibid).
7 – Body awareness and awareness about physical posture
96.3 % of the study population experienced an achieved effect regarding body and posture
awareness. The average score was 2.36 (SD = 1.10) meaning between moderate and good
effect. However, as much as 18.8 % of the people reported that they had very good positive
effect (score 4) on this topic. In the yoga classes during the 7-week course there was
extensively emphasize on body awareness and posture. This is one of the most important
factors in yoga philosophy – doing yoga exercises without awareness is simply not yoga. The
thorough focus on awareness during all yoga classes might explain the good result on this
topic.
Body awareness is also a core issues in physiotherapy. Some of the first things we
learn during physiotherapy education about patient examination are to observe and analyse
the person’s physical posture; supine, sitting standing and walking (Gross et al. 2002). This
observation and analysis is often the basis for finding out what is wrong with the patient.
From these findings we try to see if we can improve the patients problems by doing
corrections of the posture. For the patient to be able to feel any incorrect posture pattern at all,
he also needs to have some degree of awareness of his body. And furthermore, to be able to
do the corrections he certainly needs to have awareness of his body. Therefore, body
awareness can be said to be a fundament for a good physical posture and for being able to
perform adequate, stable and flexible movements. For this reason working with body
awareness and postures are important in a physiotherapy intervention (Thornquist 2003). This
focus on body awareness is also shared by therapeutically methods like e.g. Mencendieck
(1937), Feldenkrais (1972), “Awareness through movement”, Alexander technique (Brennan
25
Bachelor report 2010 – Jan Petter Engvig
1997) and “Body Awareness Therapy” (Roxendal 1985) which are methods often used by
physiotherapists.
8 – Respiration
Several informants reported positive personal experiences regarding respiration like informant
# 61: “ I have trouble with my breathing in stressful situations e.g. during exams, where I feel
that I’m not able to inhale. This problem is completely gone now”. Informant # 62 is saying:
“The best parts are breathing exercises, the focus and inward observation. Breath and
meditation dissolve much of my tensions and stress”. The quantitative results on this topic
showed that 94.9 % of the study population experienced a positive effect. The average score
was 2.29 (SD = 1.2), meaning that they perceived the effect as moderate to good. However as
much as 19.2 % of the people reported very good effect (score 4). These results would be
reasonable in contrast to the focus there is on breathing in yoga practice, and the doseresponse
relationship seems to be as expected.
Breath is one of the keystones in yoga philosophy and “Pranayama” is the common
yoga-word for breathing exercises, meaning “breath control” or “life force”. Pranayama is one
of the eightfold paths of yoga philosophy and is regarded as one of the main means for
rejuvenating the body and clearing of the mind (Feuerstein 1997). There are several specific
breathing exercises where the breath is the main focus, but breath will also always be a natural
part of the asanas and vinyasas (Iyengar 2001). Several of these postures and exercises has the
intension to open up the thorax, stretch the m. pectoralis minor and major,
sternocleidomastoideus, accessory respiratory muscles and to give more free space for the
lungs. Other common breathing exercises have a more mindful approach where you just
observe your breath and the motion your breath is making in your body (abdomen, back,
thorax etc). In this exercise you don’t try do control anything, just observe – be aware of the
perception of breathing. This approach is also very much used in the Mindfulness Based
Stress Reduction program as described by PhD Jon Kabat-Zinn at University of
Massachusetts Medical School (1990), and also by professor emeritus Andries Kroese at Aker
University Hospital, Oslo Norway (1999).
Respiration is an issue of great concern in physiotherapy because it’s so tightly linked
to body posture, musculoskeletal issues, and physiological processes in the body and also to
psychological factors (Bunkan 2008). Therefore, focus on the breath is considered important
also in physiotherapy.
26
Bachelor report 2010 – Jan Petter Engvig
9 – Mood
Questions about a persons mood is frequently used for scaling the “quality of life” or in
mapping health status regarding psychological factors and psychosomatics. If a person is in a
good mood he is also likely to tackle stress better and have a lover perception of pain (Holden
1996; Villemure 2002). Furthermore, several studies shows that to generally be in a good
mood might also contribute to a better health status overall (Holden 1996). There exist special
yoga classes where the focus is to stimulate laughter (laughter-yoga). However, in a classical
session of hatha yoga, there is little directly focus on humour, but the intention for the class is
always gently and friendly. Relaxation techniques and meditation for calming the mind and
body will also lead to a experience of better mood, simply because this a part of the
physiological relaxation response. Taking away tension and fear induces peace and joy
(Benson 1976). There are reasons to believe that these factors are among the active
ingredients in mindfulness and yoga regarding bettering the mood (Vøllestad 2007).
91 % of the study population reported a positive effect regarding better mood from yoga
practice, and 28.2 % experienced very good effect (score 4). However, the average score was
2.63 (SD = 1.28). As a general comment of this positive result I think that the high score on
this topic might be explained by the fundaments of yoga, the yoga philosophy, that have much
attention on loving kindness, non-violence, stress reduction, meditation, energy flow and life
force. These aspects are well documented in scientific studies by for example PhD Jon Kabat-
Zinn (1990). Furthermore there are reasons to believe that physical activity in it self, such as
hatha yoga, will have a positive effect on a persons mood and feeling of well-being (Hoffman
2007; Martinsen 2004). This ingredient may also contribute to the positive result on this topic.
The fact that the yoga class is a group, commonly 10-20 people, may also contribute to a
positive effect regarding better mood due to psychosocial group dynamics (Ibid). The holistic
approach f yoga might be another important psychological factor that explain the positive
effect regarding better mood. The focus on the awareness of the whole mind-body – the
experience of being a human; bodily sensations, pain, itching, temperature, hearth-beat, your
breath, emotions and thoughts. And at the core of this you will experience the Self – the core
feeling of your personal self, being who you are. The psychiatrist Roberto Assagioli argued
that this can contribute in obtaining personal insight and bring clarity, peace and enhanced
well-being (Assagioli 1965). Another factor of psychological character is the perception of
the “here and now” or “being present” which is greatly emphasized in mindfulness and yoga
(Iyengar 1979; Kabat-Zinn 1990). Many of the positive effects about this are described by
27
Bachelor report 2010 – Jan Petter Engvig
world known psychiatrist Fritz Pearls (Clarkson & Mackewn 1993). Furthermore the research
scientist Benjamin Smith is describing the feeling of “ecstasy” that may appear during a yoga
class where the mind-body are in harmony (Smith 2007). Some of the same phenomena is
described as “flow” or to be in the “zone”, by Mihaly Csikszentmihalyi (1988), when your
body seems to be in perfect harmony during a movement in physical activity. All factors
described above might help us understand what kind of “active ingredients” which exist in
yoga, and this can in a rational way explain the positive effect regarding mood.
With respect to physiotherapy theory I would look to Per Brodal (2007) and try to
understand the effect on mood according to reduced sympaticus activity and maybe increased
serum levels of oxytocin as a results of the “active ingredients” listed above. Theory from
physical activity and mental health can also be applied here (Martinsen 2004).
10 – Stress reduction
Stress reduction is one of the core topics in yoga philosophy. This is also the general
impression many people have about yoga – and its stress reducing qualities is also well
documented in many scientific studies (Lamb 2004). In the present study 98.7 % of the study
population experienced a positive stress reducing effect from yoga. This means that only one
person of 78 in total reported no effect (score 0). 23 persons out of 78 reported very good
effect (score 4) on this issue. In other words – one out three persons had a very good positive
effect from yoga regarding stress reduction. A normal pharmaceutical intervention on
psychosomatic issues will typically be much lower (Masi et al. 2010). The average score in
the yoga intervention was 2.9 (SD = 0.99), meaning that most people experienced the effect as
“good positive effect” (score 3).
The positive result and high score on the stress reduction topic may be explained by
the fact that many of the activities in a typical hatha yoga class has the intension to induce a
relaxation response – and the experience of such a response is typically perceived as “stress
reduction” (Lamb 2004, Benson 1975). On a psychological level, we can say that “stress
reduction” is for example increase of subjective well-being, decrease of anxiety, increase in
somatic awareness and self-acceptance. On the physiologically level it may involve decrease
of muscular tensions, decreased blood pressure, pulse rate, stabilizing the autonomous
nervous system, EEG alpha waves increase, respiratory and cardiovascular efficiency
increases, better conditions for circulation, and stimulation of the psychonevroendocrine and
psychonevroimmune-systems (Berntson et al. 2007; Booth 2005; Kiecolt-Glaser et al. 2010,
Kroese 1999; Lamb 2004).
28
Bachelor report 2010 – Jan Petter Engvig
To understand this effect from a physiotherapist viewpoint I will refer to Bunkan
(2008) and Thornquist (2003). Many of the techniques described there have also the same
intention as in yoga, namely to reduce sympaticus activity and to increase parasympaticus
activity.
11 – Tension headache
In the present study 30 informants reported to have problems regarding tension headache at
the beginning of the 7-week yoga course. 29 of these people (96.7 %) reported a positive
effect with an average score of 2.0 (SD = 1.2), which means moderate good positive effect.
However, as many as 20 % of the individuals in the headache group reported very good
positive effect (score 4).
Tension headache is also named stress-headache in Norwegian physical medicine (Juel
1999). This issue is of great concern for many people in daily life, and in severe cases tension
headache might develop or be the first stage of migraine. In these cases headache can be
disabling and is perceived as a major health problem (Bond 2006). The pathogenesis of
tension headache is not fully known in detail, but literature suggest that the problem is
connected with tensed muscles in the region of the shoulder arch, neck, jaw or head (Juel
1999). Typical muscles involved are m. trapezius, levator scapulae, sternocleidomasoideus,
splenius, semispinalis capitis, suboccipitalis, masseter and others (Davies 2004; Fyrand et al.
2006). Furtermore it’s most likely to believe that psychologic factors like anxiety, depression
or stress are major factors involved in tension headache (Bond 2006). One of the commonly
non-pharmacological interventions used against tension headache are relaxation techniques
(Ibid.) Some of the effect is than explained by the fact that you will reduce the tension both in
muscular structures and emotional tensions. We also know from Butler & Moseley (2003)
that a reduced level of stress and anxiety will reduce the central modulation of pain signals
and so will the perception of pain. Since there is scientific evidence of the stress reducing and
relaxation effect from yoga, there should be reasons to believe that this will induce a positive
effect regarding tension headache. The fact that there is much emphasizing on stress
reduction, relaxation and stretching of muscle groups in relevant areas might explain this
positive result.
The understanding of a headache problem from a physiotherapy perspective would be
based on an anamnesis and physical examination in order to difference tension headache from
cervicogenic headache. Treatment of tension headache would be based on the understanding
29
Bachelor report 2010 – Jan Petter Engvig
that the cause of the problem often is referred to tensed muscles in the head and neck area
(Fyrand et al. 2006).
12 – Life energy
Life energy is considered very important in yoga and the Sanskrit word for life energy or life
force is “prana” (Feuerstein 1997). Prana is one of the goals in yoga practice and much
emphasize is put on this issue in yoga philosophy. In my study as many as 94.8 %
experienced a positive change regarding life energy from doing yoga. The average score was
2.3 (SD = 1.1), which means between moderate to good positive effect. 17.9 % of the study
population experienced a very good positive change (score 4).
Life energy is not an easy issue to measure in an objective way because the term “life
energy” or vitality is not something that can be calculated by a physic parameter like Joule,
the SI standard for energy. Therefore must this “unit” for life energy in human in this study be
measured in a client centred way, and the outcome must reflect the individual’s perspective.
This way of thinking is common for several health survey forms and often referred to as
individualized outcome measures (Carswell & Donnelly 2002). Life energy is for example a
topic on the questionnaire used by the Norwegian association for the study of pain (Fredheim
et al. 2008). Life energy will often be positively correlated to mood and well-being, and
negatively correlated with stress. Life energy is also closely related to vitality, and can be an
indicator on quality of life (Ware & Sherbourn 1992).
I will try to explain the positive result in the present study by looking at the correlation
with stress reduction, relaxation and mood. All these factors also gave high scores in the study
and there are reasons to believe that an increase on these fields will achieve a better feeling of
life energy. There should also be reasons to listen to more than 3000 years of experience from
the yogi masters and take into consideration that their philosophy about prana might have
some significance (Iyengar 2005). As said about yoga in the personal comment from
informant #21: “a source for the joy of life”, informant #60: “it gives me more energy rest of
the day” and informant #68: “It gives me life energy and well being”.
In a physiotherapy context I can understand this issue with the background on what is
described in the literature about the autonomous nervous system, psychosomatics and
physical activity by e.g. Brodal (2007), Bunkan (2008), Martinsen (2004) and Thornquist
(2003).

Bachelor report 2010 – Jan Petter Engvig
13 – Personal comments
Issue 13 was an optional question and 25 out of 80 informants gave feedback on this. The idea
here was to have some qualitative information from the participants and reflects what the 7-
week yoga course has meant on an individual level, but no names are mentioned. However,
what we can read from these personal comments reflect much of what we read out of the
quantitative results. Many of the comments are highly positive and tells about increased body
awareness, breath control, relaxation, stress reduction and a sense of well being. These
comments seams to be logical when compared to the quantitative results for these topic. On
the other hand there are people who report that they probably would have gain a better effect
if there had been more than one yoga class each week. This is also as expected if we look to
theory on dose-response in physical training. One session a week is probably not enough
regarding muscle training. On the other hand the general impression from the personal
comments are highly positive and it seams like the yoga really means much for the everyday
quality of life for many of the informants on a personal level. Examples which can reflects
this may be: “This has been the highlight of the week for me”, “Yoga has been of great help
for me”, “It gives me life energy and well being”. (For all personal comments see table
Appendix II. The comments are anonymous.)
6. CONCLUSION
This study indicates that there are several health benefits from a 7-weeks hatha yoga course.
Positive effect is reported on all 12 questions asked typical for physiotherapy issues like
musculoskeletal problems and psychosomatics. The weakest effect was shown for muscular
strength and the strongest effects were found for stress reduction, relaxation response and
better mood. The results indicate much of the same trends that are reported in previous
scientific papers on this topic. From literature studies I have found arguments that might
illuminate the active ingredients in hatha yoga with respect to health effect. First, hatha yoga
is a form of physical activity, and there is now a broad consensus among scientists that
physical activity is an effective intervention with respect to several important health issues
and non-communicable diseases (WHO 2010). Second, the focus on breathing exercises in
yoga is shown to have a positive effect on the respiratory system, and also on
psychophysiology since breath and mind-body are so closely interconnected (Coulter 2001).
Third, the yoga philosophy with its focus on mindfulness, awareness, “here-and-now”
attention, non-striving, non-judgemental, acceptance, insight to Self, and self-compassion is
proven by modern psychology to be important factors in psychological processes leading to
31
Bachelor report 2010 – Jan Petter Engvig
improvement regarding depression, empowerment and self-efficacy (Assagioli 1965; Iyengar
2001; Vøllestad 2007). When all these active ingredients are put together in one unity (literary
yoga), the outcome seams to be positive. Regarding physical therapy I have discovered that
many of the physical exercises in hatha yoga are much the same as found in therapeutically
exercises from physiotherapy (Kisner & Colby 2002). In this respect yoga can be said to be
compatible to physiotherapy. Both systems are also based on a holistic philosophy regarding
humanity (Iyengar 1979; NFF 2006). We know that non-communicable diseases and life style
problems related to stress and physical inactivity are a major public health problem in Norway
and the western world (Brudevold 2008; Merson et al. 2006). With the background from
existing scientific data there should be reasons to look at hatha yoga as a suitable intervention
for fighting these problems. For further research it would have been interesting to have done
the 7-week yoga intervention in a randomised controlled study, and also with objective
measuring parameters, and not only self-perceived health effects.

Prosjektets tittel er ”Self-percived health effect from hatha yoga” og formålet med oppgaven
er å se om deltagerne ved et 7-ukers yogakurs ved Domus Athletica kan oppleve noe
helsegevinst av dette. Spørsmålene vil være typiske for det som er vanlige innenfor
fysioterapi.
Spørsmålene (1-12) er standardiserte og det skal svares med utkryssing på en skala fra 0 til 4,
og resultatene skal brukes til kvantitativ metode i oppgaven.
Spørsmål 13 er ment for utfyllende opplysninger om hva yoga har betydd for deg personlig,
men navn oppgies heller ikke her. Dataene brukes i kvalitative metode.
Spørreskjema utdeles og samles inn etter siste yogatrening i uke 7 av kurset. Utfylling skjer
på stedet. Spørsmål kan stilles hvis det er noe dere lurer på. Skjema legges i konvolutt slik at
ingen uvedkommende ser hva dere har skrevet. Kun undertegnende vil se skjemaene i ettertid
for databehandling av resultatene og har taushetsplikt om evt personlige forhold. Evt.
personlig data holdes konfidensielt.
Prosjektet avsluttes 5.mars 2010, og resultatene fra studien leves da som en bacheloroppgave.

korrelert til kjønn og alder. Utfylt spørreskjema makuleres etter at oppgaven er levert.
