Yoga and Anxiety: A Meta-Analysis of Randomized Controlled TrialsZoogman, Sarah Elizabeth January 2016 (has links)
The aim of this study was to investigate the effect of yoga on anxiety using meta-analytic methods, examining overall effect size, the effect size of sub-categories of dependent variables, and moderation.
A systematic search was conducted for published randomized controlled trials on yoga and anxiety on electronic databases over key terms. Reference lists of quantitative studies and literature review articles were inspected for additional articles. Once included studies were determined, outcome data were extracted and moderators were coded across studies in order to characterize differences in study sample, delivery method, and type of dependent variable. Effect size aggregation and omnibus analyses were performed, and moderator tests were conducted.
Results support the hypothesis that yoga significantly decreases anxiety symptoms, in addition to symptoms more globally (i.e., anxiety and other mental health outcomes, physical health outcomes, etc taken in aggregate). Results from sub-omnibus analysis show significant effects of the yoga intervention on biological measures, non-anxiety mental health outcomes, physical health measures, stress, mental and physical health outcomes combined, and life satisfaction. In addition, significant moderation was found by location, with highest effects appearing in Indian samples.

Wirksamkeit einer Yogatherapie bei Tumorpatienten auf Angst, Depressivität und Fatigue - eine randomisierte kontrollierte Studie / Effect of Yoga Therapy on Symptoms of Anxiety, Depression and Fatigue in Cancer Patients - a Randomised Controlled TrialHardörfer, Katrin January 2018 (has links) (PDF)
Viele Tumorpatienten leiden unter Symptomen von Angst, Depressivität und Fatigue. Yoga als komplementäre und alternative Medizin ist in den letzten Jahren immer mehr in den Fokus der Forschung gerückt. Es wurden schon zahlreiche Studien durchgeführt, die kurzfristige Effekte bei Tumorpatienten zeigen konnten. Diese Ergebnisse beschränkten sich jedoch zumeist auf Brustkrebspatientinnen und konnten daher noch nicht verallgemeinert und so für ein breites klinisches Setting zugänglich gemacht werden.
Die vorliegende Dissertation untersuchte die Wirksamkeit einer Yogaintervention bei Tumorpatienten unterschiedlicher Tumorentität. Die Effekte auf die Belastun¬gen Angst, Depressivität und Fatigue wurden betrachtet. Es wurden die Hypo¬thesen formuliert, dass durch eine achtwöchige Yogaintervention die Outcomes Angst, Depressivität und Fatigue signifikant im Vergleich zur Kontrollgruppe gesenkt werden können. Außerdem wurden die Erwartungen an die Yogainter¬vention sowie ihre Bewertung erfragt.
Das Studiendesign zur Überprüfung der Hypothesen bestand aus einer rando-misiert kontrollierten Studie mit einer achtwöchigen Yogaintervention im Vergleich mit einer Wartekontrollgruppe. Die Yogasitzungen dauerten wöchent¬lich 60 Minuten und wurden in Gruppen von zehn bis zwölf Probanden unter der Leitung einer zur Yogatherapeutin ausgebildete Psychoonkologin durchgeführt. Die Yogaintervention enthielt Körper- sowie Atemübungen und Meditation. Es wurden Selbsteinschätzungsbögen zum Prä- und Postinterventionszeitpunkt verwandt. Angstsymptome wurden mit dem GAD-7-Fragebogen, Depressivität mit dem PHQ-2-Fragebogen und Fatigue mit dem EORTC-QLQ FA13-Fragebogen ermittelt. Die Kontrollgruppe erhielt eine Yogatherapie nach dem achtwöchigen Wartezeitraum.
Die Stichprobe beinhaltete gemischte Diagnosen und fast die Hälfte der Probanden wies eine andere Tumorentität als Mammakarzinom auf. 90% der Teilnehmer bildeten Frauen. In der Interventionsgruppe konnte im Vergleich zur Kontrollgruppe auf Angst ein großer signifikanter Effekt gefunden werden. Depressivität und Fatigue zeigten keinen signifikanten Effekt. Die Yogatherapie wurde, vor allem hinsichtlich Aufbau und Anleitung, überwiegend gut bewertet und die Erwartungen erfüllt. Aus den Befragungen ging hervor, dass die Teil¬nehmer subjektiv von der Yogaintervention profitierten und selbst Yoga weiter durchführen möchten sowie die Yogaintervention auch anderen Tumorpatienten weiterempfehlen würden.
Zusammenfassend kann man aus dieser Studie schließen, dass eine Yoga-intervention eine vielversprechende, supportive Therapie zu sein scheint. Eine Verallgemeinerung der Ergebnisse für ein breites klinisches Setting konnte vor allem mit dem hohen Frauenanteil und dem hohen Anteil an Brustkrebs-patientinnen nicht ohne weiteres vorgenommen werden. Es bedarf weiterer Forschung, die ihren Schwerpunkt auf größer angelegte Stichproben mit ver-schiedenen Tumorentitäten und einem ausgeglichenen Geschlechterverhältnis legt. / Summary
Background: Many cancer patients suffer from symptoms of anxiety, depression and fatigue. Supportive treatments are increasingly used to alleviate distress in cancer. In this study, effects of yoga on these symptoms are examined.
Methods: We performed a randomized controlled study on cancer patients with mixed diagnoses comparing yoga therapy with a waiting-list control group. We measured anxiety symptoms with the General Anxiety Disorder scale (GAD 7), depressive symptoms with the Patient Health Questionnaire-2 (PHQ 2) and fatigue with the European Organisation for Research and Treatment in Cancer Fatigue Scale (EORTC QLQ FA13). The yoga therapy was carried out in weekly sessions of 60 minutes each for 8 weeks. The exercises provided restrained body and breathing exercises as well as meditations. The control group didn’t receive any yoga therapy during waiting.
Results: A total of 70 subjects participated in the study. Anxiety was significantly reduced by the yoga therapy in the intervention group compared to the control group (p= 0.005). However, the yoga therapy did not show any significant effects on depression (p= 0.21) and fatigue (p= 0.11) compared to the control group.
Conclusion: Yoga therapy may be used to alleviate anxiety symptoms in cancer patients and should be the subject of further research.

The psychological and physiological effects of yoga on childrenCrowley, Anna, anna.crowley@arafemi.org.au January 2002 (has links)
The rise in popularity of health practices such as yoga coincides with a period of
growing publicity about the benefits of promoting positive health from an early age. Despite
this, empirical research in the field is limited. Thus, the aim of the current study was to
assess the psychological and physiological impact of a brief yoga program for children
using a randomised placebo-control design. Twenty-two school-girls aged 8-10 were
recruited to take part in a 6-session after-school program. Participants were randomly
allocated to either yoga classes or recreation classes. Heart rate change and respiration rate
were measured pre-post program as physiological indicators of relaxation. For mental
wellbeing, pre- and post-session mood and pre- and post-program self-esteem and physical
self-worth variables were assessed. Later, a replication study was conducted where yoga
was offered to the former recreation group.
Contrary to expectations, no significant changes were found on the physiological
indicators of relaxation. Global self-esteem and physical self-worth variables also remained
constant in both the yoga and recreation groups. As hypothesised, significant reductions in
anxious mood were consistently reported from the second session onwards following yoga
classes. Contrary to expectations however, depressed mood remained unchanged in either
group. Results of the follow-up study confirmed most of the findings of the main study,
except for a small improvement on the physical self-worth variable of self-perceived sports
competency, and no significant post-session mood changes. Nonetheless qualitative data
suggested that this group also experienced anxiety reduction following yoga practice.
The results of the project remain speculative because of the small sample size and
generous criteria used to determine statistical significance. Despite this, it was concluded
that while brief yoga programs might have little impact on children�s overall self-esteem or
physical self- perceptions, especially where children are physically active and already enjoy
moderate to high levels of self-esteem, yoga classes may contribute to reductions in
immediate anxiety levels. While the ability to relax voluntarily was not demonstrated by the
end of program, it was suggested that a longer yoga program which incorporated more overt
teaching of relaxation skills might produce such a result. This and other recommendations
for future research are presented and the implications for the understanding of positive
health are discussed.

Yoga and self-esteem : exploring change in middle-aged womenJunkin, Sarah Elizabeth 22 August 2007
Of the numerous psychological constructs self-esteem is the most known. It is well documented that having high levels of self-esteem is associated with positive health implications. Self-esteem is theorized as a global and stable construct impacted by both academic and non-academic domains. The physical domain compartmentalized within the non-academic domain, is used to look at self-esteem related to physical self-perceptions. In the physical domain, the Exercise and Self-Esteem Model (EXSEM) (Sonstroem & Morgan, 1989) was developed to measure changes in self-esteem, physical competence, physical acceptance, and self-efficacy across an exercise intervention. Fox (2000b) suggested that middle-age marks a time where positive changes to self-esteem are possible. For women, middle-age can be accompanied by several challenges including a physical body that moves further from societys ideal (i.e., young, beautiful, and thin). Hatha yoga is an exercise practice that has become popular in North America in recent years, especially with middle-aged adults, and may represent an ideal activity to be used within the EXSEM as it emphasizes both physical competence and acceptance. <p>The purpose of the study was to utilize the EXSEM as a framework to examine self-esteem, physical competence, physical acceptance, and yoga self-efficacy constructs for middle-aged women participating in a 12-week Hatha yoga intervention. An additional exploratory objective of the study was to examine potential changes in mindfulness consisting of observing, describing, acting with awareness, and accepting without judgement for middle-aged women participating in a 12-week Hatha yoga intervention. <p>Participants in the study were 51 women (M age 49.3 6.1; yoga group, n = 21; control group, n = 30) of predominantly White ethnicity (92%). Descriptive information about the sample via a demographics form and an Eastern philosophy familiarity open-ended question, and the following measures, Godin Leisure-Time Exercise Questionnaire (GLTEQ; Godin, & Shephard, 1985), Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965), Physical Self-Perception Profile (PSPP; Fox & Corbin, 1989), Body Esteem Scale (BES; Franzoi, & Shields, 1984), Body Image Visual Analog Scale (BIVAS), Yoga Self-Efficacy Scale (YSES), and the Kentucky Inventory of Mindfulness Skills (KIMS; Baer, Smith, & Allen, 2004) were collected at pre-test and post-test (YSES was administered an additional time for the yoga group only). Doubly multivariate analyses using SPSS (version 14.0) examined four statistical models to answer research questions and help negotiate several dependent variables in the research design. Model 1 looked at higher order constructs in the EXSEM (i.e., RSES, physical self-worth subscale of the PSPP, BES, BIVAS, and YSES). Model 2 was identical to model 1 with the exception of including lower order domain items for physical competence (i.e., PSPP subscales of sport competence, physical strength, physical condition, attractive body). Model 3 looked at subscales of YSES (i.e., standing poses, forward bends, back bends, twists, and seated/supine poses), whereas model 4 examined subscales of KIMS only (i.e., observe, describe, act with awareness, accept without judgement). <p>Following the doubly multivariate analysis, PSPP subscales showed significant group by time interactions; follow-up univariate tests, p < .05, showed significance on PSW F(1, 49) = 12.22, conditioning subscale of PSPP F(1, 49) = 10.65, strength subscale on PSPP F(1, 49) = 13.11, BIVAS F(1, 49) = 6.45, YSE total score F(1, 49) = 9.84, and YSE subscales of forward bends F(1, 49) = 17.84, twists F(1, 49) = 8.18, and seated/supine poses F(1, 49) = 6.21, and observation subscale of KIMS F(1, 49) = 12.16, p < .05. In all cases, the yoga group improved more over time than the control group.<p>General support for the use of the EXSEM for middle-aged women participating in Hatha yoga over 12-weeks was noted with changes in yoga self-efficacy for total score, twists, forward bends, and seated/supine poses; physical competence of physical self-worth, body conditioning, and physical strength; and physical acceptance (BIVAS). A major finding was that no overall change in self-esteem was found with a sample whose means for self-esteem were similar to previous research with middle-aged women. Similarly, partial support for mindfulness with changes in observing following the 12-week Hatha yoga intervention was found. Future research should focus on further developing appropriate measurement of physical acceptance; the appropriateness of EXSEM for examining Hatha yoga should be considered; qualitative methods should be used to gain additional insight into the process of Hatha yoga participation for middle-aged women.

Yoga i Sverige : En komparativ studie av tidsskriften Sökaren mellan åren 1964-1974 och 1998-2008.Sirén, Bettina January 2012 (has links)
This study examines how yoga is presented in a Swedish journal called Sökaren. Sweden is often presented as one of the most secular states in the world, and for that reason it is interesting to examine the Swedish way of religiosity by looking, in this case, at the depiction of yoga. I compare two periods of time, the first one from 1964 to 1974 and the latter from 1998 to 2008. I will thereby be able to examine tendencies and changes in the presentation of yoga. For a further understanding of the context around the elected periods this study introduces religiosity in Swedish society, such as Christianity and the New Age movement. An introduction of the Yoga Sutra, the Hindu tradition and a yogic view on the body is further included in the background.

Sirsasana (headstand) technique alters head/neck loading : considerations for safetyHector, Rachel Elizabeth 24 July 2012 (has links)
Headstand, the king of all yoga poses, requires practitioners to support the full body with the forearms and crown of the head. A goal of novice and expert practitioners alike, sirsasana performance technique significantly modifies head and neck loads. This study examined the weight-bearing responsibility of the head and neck (separate from the arms) at moments of peak force during entry, stability, and exit of three typical performance methods. The three methods were: symmetrical extended leg (SE), symmetrical flexed leg (SF), and asymmetrical flexed leg (AF). Three groups of 15 participants each (2 males, 13 females) were formed, each group performing one technique. All 45 subjects (18-60 years of age) reported an active yoga practice including sirsasana with no record of cervical injury. After a 10 min warm up, participants performed three headstands. Kinematic and kinetic Vicon data were analyzed to locate peak forces acting on the head, loading rate of those forces, center of pressure, and neck angle at C3 in the frontal plane. Force plate data revealed flexed leg techniques produced the greatest forces during entry and nominal forces on exit. The SE condition produced lower forces on entry as well as slower loading rates during stability. In the frontal plane, neck angle about C3 tended towards neutral, or natural cervical lordosis, in SE and flexion in SF and AF during entry. COP showed no significant differences between groups; however, lateral movement at the apex of the head was markedly larger than movement in the sagittal plane for all techniques. Previous research has shown flexed loading, rapid loading and larger loads can increase potential damage to the cervical spine especially in women and aging individuals. As that population is heavily represented in yoga studios, the data support the conclusion that modifying headstand technique may reduce some of the mechanical risks of headstand. / text
