    Input: BACKGROUND There has been limited study of yoga training as a complementary exercise strategy to manage the symptom of dyspnea in patients with chronic obstructive pulmonary disease ( COPD ) . PURPOSE The primary purpose of this pilot study was to evaluate a yoga program for its safety , feasibility , and efficacy for decreasing dyspnea intensity ( DI ) and dyspnea-related distress ( DD ) in older adults with COPD . METHODS Clinical ly stable patients with COPD ( n = 29 ; age 69.9 + /- 9.5 ; forced expiratory volume in 1 second ( FEV(1 ) ) 47.7 + /- 15.6 % predicted ; female = 21 ) were r and omized to a 12-week yoga program specifically design ed for people with COPD or usual-care control  ( UC ) . The twice-weekly yoga program included asanas ( yoga postures ) and visama vritti pranayama ( timed breathing ) . Safety measure outcomes included heart rate , oxygen saturation , dyspnea , and pain . Feasibility was measured by patient-reported enjoyment , difficulty , and adherence to yoga sessions . At baseline and at 12 weeks , DI and DD were measured during incremental cycle ergometry and a 6-minute walk ( 6MW ) test . Secondary efficacy outcomes included physical performance , psychologic well-being , and health-related quality of life ( HRQoL ) . RESULTS Yoga training was safe and feasible for patients with COPD . While yoga training had only small effects on DI after the 6MW test ( effect size [ ES ] , 0.20 ; p = 0.60 ) , there were greater reductions in DD in the yoga group compared to UC ( ES , 0.67 ; p = 0.08 ) . Yoga training also improved 6MW distance ( + 71.7 + /- 21.8 feet versus -27.6 + /- 36.2 feet ; ES = 0.78 , p = 0.04 ) and self-reported functional performance ( ES = 0.79 , p = 0.04 ) compared to UC . There were small positive changes in muscle strength and HRQoL. CONCLUSIONS Elderly patients with COPD participated safely in a 12-week yoga program especially design ed for patients with this chronic illness . After the program , the subjects tolerated more activity with less DD and improved their functional performance . These findings need to be confirmed in a larger , more sufficiently powered efficacy study OBJECTIVE health-related quality of life ( HRQOL ) and mental well-being are associated with healthy ageing . Physical activity positively impacts both HRQOL and mental well-being .  Yoga is a physical activity that can be modified to suits the needs of older people and is growing in popularity . We conducted a systematic review with meta- analysis to determine the impact of yoga-based exercise on  HRQOL and mental well-being in people aged 60 + . METHODS search es were conducted for relevant trials in the following electronic data bases ; MEDLINE , EMBASE , Cochrane Central Register of Controlled Trials , CINAHL , Allied and Complementary Medicine Data base , PsycINFO and the Physiotherapy Evidence Data base ( PEDro ) from inception to January 2017 . Trials that evaluated the effect of physical yoga on HRQOL and /or on mental well-being  in people aged 60 + years were included . Data on HRQOL and mental well-being were extracted . St and ardised mean differences and 95 % confidence intervals ( CI ) were calculated using r and om effects models . Method ological quality of trials was assessed using the PEDro scale . RESULTS twelve trials of high method ological quality ( mean PEDro score 6.1 ) , totalling 752 participants , were identified and provided data for the meta- analysis . Yoga produced a medium effect on HRQOL ( Hedges ' g = 0.51 , 95 % CI 0.25 - 0.76 , 12 trials ) and a small effect on mental well-being ( Hedges ' g = 0.38 , 95 % CI 0.15 - 0.62 , 12 trials ) . CONCLUSION yoga interventions result ed in small to moderate improvements in both HRQOL and mental well-being in people aged 60 + years . Further , research is needed to determine the optimal dose of yoga to maximise health impact . PROSPERO REGISTRATION NUMBER ( CRD42016052458 ) BACKGROUND Despite yoga 's popularity , few clinical trials have employed rigorous methodology to systematic ally explore its functional benefits compared with more established forms of exercise . The objective of this study was to compare the functional benefits of yoga with the conventional stretching-strengthening exercises recommended for adults . METHODS Sedentary healthy adults ( N = 118 ; M age = 62.0 ) participated in an 8-week ( three times a week for 1 hour ) r and omized controlled trial , which consisted of a Hatha yoga group ( n = 61 ) and a stretching-strengthening exercise group ( n = 57 ) . St and ardized functional fitness tests assessing balance , strength , flexibility , and mobility were administered at baseline and postintervention . RESULTS A repeated measures multivariate analysis of variance showed a significant time effect for measures of balance [ F(3,18 ) = 4.88 , p < .01 , partial η(2 ) = .45 ] , strength [ F(2,19 ) = 15.37 , p < .001 , partial η(2 ) = .62 ] , flexibility [ F(4,17 ) = 8.86 , p < .001 , partial η(2 ) = .68 ] , and mobility [ F(2,19 ) = 8.54 , p < .002 , partial η(2 ) = .47 ] . Both groups showed significant improvements on measures of balance ( left-right leg and four square step ) ; strength ( chair st and s and arm curls ) ; flexibility ( back scratch and sit- and -reach ) ; and mobility ( gait speed and 8-feet up and go ) , with partial η(2 ) ranging from .05 to .47 . CONCLUSIONS These data suggest that regular yoga practice is just as effective as stretching-strengthening exercises in improving functional fitness . To our knowledge , this is the first study to examine functional benefits of yoga in comparison with stretching-strengthening exercises in sedentary , healthy , community-dwelling older adults . These findings have clinical implication s as yoga is a more amenable form of exercise than strengthening exercises as it requires minimal equipment and can be adapted for individuals with lower levels of functioning or disabilities There is growing evidence that yoga may offer a safe and cost-effective intervention for Type 2 Diabetes mellitus ( DM 2 ) . However , systematic review s are lacking . This article critically review s the published literature regarding the effects of yoga-based programs on physiologic and anthropometric risk profiles and related clinical outcomes in adults with DM 2 . We performed a comprehensive literature search using four computerized English and Indian scientific data bases . The search was restricted to original studies ( 1970–2006 ) that evaluated the metabolic and clinical effects of  yoga in adults with DM 2 . Studies targeting clinical population s with cardiovascular disorders that included adults with comorbid DM were also evaluated . Data were extracted regarding study design , setting , target population , intervention , comparison group or condition , outcome assessment , data analysis and presentation , follow-up , and key results , and the quality of each study was evaluated according to specific predetermined criteria . We identified 25 eligible studies , including 15 uncontrolled trials , 6 non-r and omized controlled trials and 4 r and omized controlled trials ( RCTs ) . Overall , these studies suggest beneficial changes in several risk indices , including glucose tolerance and insulin sensitivity , lipid profiles , anthropometric characteristics , blood pressure , oxidative stress , coagulation profiles , sympathetic activation and pulmonary function , as well as improvement in specific clinical outcomes .  Yoga may improve risk profiles in adults with DM 2 , and may have promise for the prevention and management of cardiovascular complications in this population . However , the limitations characterizing most studies preclude drawing firm conclusions . Additional high- quality RCTs are needed to confirm and further eluci date the effects of st and ardized yoga programs in population s with DM 2 The effect of practicing yoga for the management of type II Diabetes  was assessed in this systematic review through search ing related electronic data bases and the grey literature to the end of May 2007 using Ovid . All r and omized controlled clinical trials ( RCTs ) comparing yoga practice with other type of intervention or with regular practice or both , were included regardless of language or type of publication . Each study was assessed for quality by two independent review ers . Mean difference was used for summarizing the effect of each study outcomes with 95 % confidence intervals . Pooling of the studies did not take place due to the wide clinical variation between the studies . Publication bias was assessed by statistical methods . Five trials with 363 participants met the inclusion criteria with medium to high risk of bias and different intervention characteristics . The studies ’ results show improvement in outcomes among patients with diabetes type II .  These improvements were mainly among short term or immediate diabetes outcomes and not all were statistically significant . The results were inconclusive and not significant for the long-term outcomes . No adverse effects were reported in any of the included studies . Short-term benefits for patients with diabetes  may be achieved from practicing yoga . Further research is needed in this area . Factors like quality of the trials and other method ological issues should be improved by large r and omized control trials with allocation concealment to assess the effectiveness of yoga on diabetes type II . A definitive recommendation for physicians to encourage their patients to practice yoga can not be reached at present BACKGROUND AND OBJECTIVE Sleep in older persons is characterized by decreased ability to stay asleep , result ing in fragmented sleep and reduced daytime alertness . Pharmacological treatment of insomnia in older persons is associated with hazardous side effects . Hence , the present study was design ed to compare the effects of Yoga and Ayurveda on the self rated sleep in a geriatric population . METHODS Of the 120 residents from a home for the aged , 69 were stratified based on age ( five year intervals ) and r and omly allocated to three groups i.e. , Yoga ( physical postures , relaxation techniques , voluntarily regulated breathing and lectures on yoga philosophy ) , Ayurveda ( a herbal preparation ) , and Wait-list control ( no intervention ) . The groups were evaluated for self- assessment of sleep over a one week period at baseline , and after three and six months of the respective interventions . RESULTS The Yoga group showed a significant decrease in the time taken to fall asleep ( approximate group average decrease : 10 min , P<0.05 ) , an increase in the total number of hours slept ( approximate group average increase : 60 min , P < 0.05 ) and in the feeling of being rested in the morning based on a rating scale ( P<0.05 ) after six months . The other groups showed no significant change . INTERPRETATION AND CONCLUSION Yoga practice improved different aspects of sleep in a geriatric population CONTEXT There are potential benefits of mind-body techniques on cognitive function because the techniques involve an active attentional or mindfulness component , but this has not been fully explored . OBJECTIVE To determine the effect of yoga on cognitive function , fatigue , mood , and quality of life in seniors . DESIGN R and omized , controlled trial comparing yoga , exercise , and wait-list control groups . PARTICIPANTS One hundred thirty-five generally healthy men and women aged 65 - 85 years . INTERVENTION Participants were r and omized to 6 months of Hatha yoga class , walking exercise class , or wait-list control . Subjects assigned to classes also were asked to practice at home . MAIN OUTCOME MEASURES Outcome assessment s performed at baseline and after the 6-month period included a battery of cognitive measures focused on attention and alertness , the primary outcome measures being performance on the Stroop Test and a quantitative electroencephalogram ( EEG ) measure of alertness ; SF-36 health-related quality of life ; Profile of Mood States ; Multi-Dimensional Fatigue Inventory ; and physical measures related to the interventions . RESULTS One hundred thirty-five subjects were recruited and r and omized . Seventeen subjects did not finish the 6-month intervention . There were no effects from either of the active interventions on any of the cognitive and alertness outcome measures . The yoga intervention produced improvements in physical measures ( eg , timed 1-legged st and ing , forward flexibility ) as well as a number of quality -of-life measures related to sense of well-being and energy and fatigue compared to controls . CONCLUSIONS There were no relative improvements of cognitive function among healthy seniors in the yoga or exercise group compared to the wait-list control group . Those in the yoga group showed significant improvement in quality -of-life and physical measures compared to exercise and wait-list control groups Objectives .

Conclusion This review is the first to compare the effects of yoga with active and inactive controls in older adults not characterised by a specific clinical condition .
Results indicate that yoga interventions improve multiple physical function and HRQoL outcomes in this population compared to both control conditions .
This study provides robust evidence for promoting yoga in physical activity guidelines for older adults as a multimodal activity that improves aspects of fitness like strength , balance and flexibility , as well as mental wellbeing .
