Effects of yoga on well-being and healthy ageing: study protocol for a randomised controlled trial (FitForAge)

Acceptability, feasibility, and effectiveness of WE-SURF™: a virtual supervised group-based fall prevention exercise program among older adults

Conducted physically, supervised group-based falls prevention exercise programs have demonstrated effectiveness in reducing the risk of falls among older adults. In this study, we aimed to assess the acceptability, feasibility, and effectiveness of a virtual supervised group-based falls prevention exercise program (WE-SURF™) for community-dwelling older adults at risk of falls.

METHOD

A preliminary study utilizing virtual discussions was conducted to assess the acceptability of the program among six older adults. Effectiveness was evaluated in a randomized controlled feasibility study design, comprising 52 participants (mean age: 66.54; SD: 5.16), divided into experimental (n = 26) and control (n = 26) groups. The experimental group engaged in a 6-month WE-SURF™ program, while the control group received standard care along with a fall's prevention education session. Feasibility of the intervention was measured using attendance records, engagement rates from recorded videos, dropouts, attrition reasons, and adverse events.

RESULTS

Preliminary findings suggested that WE-SURF™ was acceptable, with further refinements. The study revealed significant intervention effects on timed up and go (TUG) (η2p:0.08; p < 0.05), single leg stance (SLS) (η2p:0.10; p < 0.05), and lower limb muscle strength (η2p:0.09; p < 0.05) tests. No adverse events occurred during the program sessions, and both attendance and engagement rates were high (> 80% and 8/10, respectively) with minimal dropouts (4%). The WE-SURF™ program demonstrated effectiveness in reducing the risk of falls while enhancing muscle strength and balance.

CONCLUSION

In conclusion, WE-SURF™ was demonstrated to be an acceptable, feasible, and effective virtual supervised group-based exercise program for fall prevention in community-dwelling older adults at risk of falls. With positive outcomes and favourable participant engagement, WE-SURF™ holds the potential for wider implementation. Further research and scaling-up efforts are recommended to explore its broader applicability. (Registration number: ACTRN 12621001620819).

Social Participation: A Strategy to Manage Depression in Disabled Populations

This study aimed to investigate whether social participation (SP) can decrease depressive symptom severity in disabled older adults. A total of 5,937 disabled participants (4877, 1970, 219, and 8 participants responding 1, 2, 3, 4 times, respectively), obtained from the China Health and Retirement Longitudinal Study, were enrolled in our analysis. Based on pooled Ordinary Least Square regressions, SP was associated with decreased depressive symptom severity, and this association was significant in recreational activities and interacting with friends. For brain-disabled respondents, the association was not significant. SP is effective in decreasing depressive symptom severity in disabled older populations. Diversified activities and targeted interventions should be applied to specified older disabled populations to prevent depression.

Effects of yoga on physical and psychological health among community-dwelling older adults: A systematic review and meta-analysis

OBJECTIVES

To synthesise and critically appraise the quality of existing evidence about the effects of yoga on physical and psychological outcomes among older adults.

DESIGN

A systematic review and meta-analysis.

PARTICIPANTS

Participants aged 60 and above.

MEASUREMENTS

Nine English and two Chinese electronic bibliographic databases, including MEDLINE OvidSP, PsycINFO, AMED, EMBASE, Global Health, PubMed, Scopus, CINAHL, Cochrane Library, Hyread and WanFang databases, were searched. Randomised controlled trials (RCT) of yoga on physical and psychological outcomes among older adults were included. Meta-analysis was conducted for outcomes studied in three or more studies, otherwise narrative synthesis was performed.

RESULTS

Fifteen studies were included for review. The results of meta-analysis after sensitivity analysis showed that yoga significantly improved balance (SMD = 0.81, 95% CI: 0.48-1.14, p < .001, II2  = 59%), flexibility (SMD = 0.38, 95% CI: 0.07-0.68, p = .020, II2 34%), muscle strength (SMD = 0.49, 95% CI: 0.18-0.79, p = .002, I2 43%) and depressive symptoms (SMD = 0.50, 95% CI = 0.09-0.91, p = .01, I2 0%). There was insufficient data for meta-analysis on gait and other psychological outcomes. Narrative synthesis suggested that yoga has positive effects on reducing anxiety, but its effects on improving gait and reducing stress among older adults were inconclusive.

CONCLUSION

The results of this review supported the beneficial effects of yoga on physical outcomes among older adults, but the heterogeneity across studies was relatively high. Evidence related to the effect on psychological outcomes was limited.

Sticking with it? Factors associated with exercise adherence in people with alcohol use disorder

BACKGROUND

Emerging evidence suggests that exercise may be an efficacious treatment for alcohol use disorder (AUD), but adherence is suboptimal. We examined factors associated with adherence to an exercise intervention for non-treatment seeking adults with AUD.

METHODS

This secondary analysis of a randomized controlled trial included 95 physically inactive adults aged 18-75 years with clinician-diagnosed AUD. Study participants were randomly assigned to 12-weeks fitness centre-based, supervised aerobic exercise or yoga classes and asked to attend at least three times/week. Adherence was assessed both objectively (based on use of a keycard at entry) and subjectively using an activity calendar. The association between AUD and other predictor variables with adherence was assessed using logistic and Poisson regression models.

RESULTS

Just under half of participants (47/95, 49%) completed ≥ 12 supervised exercise sessions. When both supervised classes and self-reported sessions were included, 32/95 (34%) participants completed ≤ 11 sessions, 28/95 (29%) did 12-23 sessions and 35/95 (37%) completed ≥ 24 sessions. In univariate logistic regression analyses, lower education was associated with non-adherence (<12 sessions) (OR = 3.02, 95%CI = 1.19-7.61). In models adjusted for demographic and clinical variables, moderate AUD (OR = 0.11, 95%CI = 0.02-0.49) and severe AUD (OR = 0.12, 95%CI = 0.02-0.69) were associated with non-adherence, when compared to low severity AUD. Higher body mass index (OR = 0.80, 95%CI = 0.68-0.93) was also associated with non-adherence. Results were materially the same when objective and subjective adherence data were combined.

CONCLUSION

Adults with AUD can be supported to engage in yoga and aerobic exercise. Additional support may be required for those with moderate or severe AUD, higher BMI, and lower education.

Effects of Yoga and Aerobic Exercise on Verbal Fluency in Physically Inactive Older Adults: Randomized Controlled Trial (FitForAge)

Purpose

To compare the effects on verbal fluency of a supported yoga-based exercise intervention to an aerobic exercise intervention and a wait-list control group.

Participants and Methods

Eighty-two physically-inactive but otherwise healthy adults (mean age 72.5 years, range 65-85, 77% female) were recruited into a 12-week, three-group, parallel randomized controlled trial. Participants were supported to complete ≥3 Hatha yoga classes per/week or ≥3 structured aerobic exercise sessions/week. A wait-list control group continued usual daily activities only. Verbal fluency, including total-FAS, animals, and verbs, was assessed before and after interventions. Group effects were assessed using analysis of covariance (ANCOVA).

Results

Twenty-seven participants were randomized to yoga, 29 to aerobic exercise and 26 to a waitlist. At 12-week follow-up, compared to baseline, there were increases in mean total-FAS in the yoga (+5.0 words, p=0.002) and aerobic exercise groups (+6.6 words, p=0.004). Mean total-FAS in the wait-list control group remained stable (-0.5 words, p=0.838). There were medium-magnitude estimated treatment effects on total-FAS for yoga versus wait-list control and aerobic exercise versus wait-list control: Hedges' g=0.51 (p=0.213) and 0.57 (p=0.098) respectively. In addition, small-to-medium magnitude estimated treatment effects were seen on animals and verbs for yoga versus wait-list control and aerobic exercise versus wait-list control: g=0.28 (p=0.155), 0.19 (p=0.766) and 0.50 (p=0.085), 0.59 (p=0.233) respectively.

Conclusion

Participation in yoga or aerobic exercise was associated with estimated improvements in verbal fluency compared to a non-active control group. Yoga and aerobic exercise may be promising approaches by which to promote cognitive function among older adults.

Older Women Who Practiced Physical Exercises before the COVID-19 Pandemic Present Metabolic Alterations and Worsened Functional Physical Capacity after One Year of Social Isolation

Background: Because the consequences of the lifestyle changes in older adults associated with the social isolation imposed in response to the COVID-19 pandemic are not fully understood, here, we investigated the effects of one year of social isolation imposed by COVID-19 on the metabolic parameters and functional physical capacity of older women who regularly practiced physical exercises before the pandemic. Methods: Systemic lipid and protein profiles, estimated creatinine clearance (ECC), and functional physical capacity (FPC) were assessed before (January-February 2020) and 12 months after social isolation in 30 older women (mean age 73.77 ± 6.22) who were engaged in a combined-exercise training program for at least 3 years before the COVID-19 pandemic. Results: In this group, we observed increased plasma levels of triglycerides and creatinine, an increase in the time necessary to perform gait speed and time-up-and-go tests, and reduced muscle strength assessed by the handgrip test and ECC post-COVID-19 pandemic relative to values recorded pre-pandemic. In addition, we observed significant correlations (both negative and positive) between anthropometric, some metabolic parameters, and physical tests. Conclusion: One year of interruption of physical exercise practice imposed in response to the COVID-19 pandemic significantly altered some systemic metabolic parameters and worsened ECC and FPC in older women.

Postural stability and flexibility responses of yoga training in women: Are improvements similar in both sexes?

The researchers' aim is to examine the postural stability and flexibility responses of yoga training in women. The authors conducted the yoga training program 2 days a week and they assessed flexibility using the sit and reach test, trunk hyperextension test and trunk lateral flexion test. The researchers measured static and dynamic balance employing the device and database system. Then, the authors repeated all assesments were at the end of the first, the fifth and the tenth sessions. As a result of this study, the researchers revealed that the male participants had significantly poorer results in a single parameter (longitudinal sway) when compared with the female group, but the groups were statistically equivalent in this parameter after the first yoga training session. The authors also revealed that yoga was effective in improving flexibility among healthy young adults of both sexes, although the males showed greater improvement than females in the flexibility results.

Effects of yoga and aerobic exercise on wellbeing in physically inactive older adults: randomized controlled trial (FitForAge)

OBJECTIVE

To compare the effects of yoga and aerobic exercise (AE) on wellbeing in physically inactive, but otherwise healthy older adults. A secondary objective was to assess and compare the frequency of adverse events associated with yoga and AE.

DESIGN

Twelve-week, three-group, parallel randomized controlled trial with blinded follow-up assessment.

INTERVENTIONS

Participants were supported to complete ≥3 Hatha yoga classes/week or ≥3 AE sessions/week. A wait-list control (WLC) group continued usual daily activities.

MAIN OUTCOME MEASURE

Change in wellbeing, assessed using the Satisfaction with Life Scale (SWLS) and Life Satisfaction Index-Z (LSI),at baseline and at 12-week follow up.

RESULTS

In total, 82 adults (mean age 72.5 years, range 65-85, 77% female) were recruited. Of these, 27 were randomized to yoga, 29 to aerobic exercise and 26 to wait-list control. Medium-magnitude treatment effects (Hedges' g) were seen for yoga versus WLC and AE versus WLC(SWLS, g = 0.65 and 0.56; LSI, g = 0.54 and 0.54, respectively). In per-protocol analyses, larger effect sizes were found (SWLS, g = 0.72 and 0.66; LSI, g = 0.76 and 0.76, respectively). Adverse events were less frequent in the yoga group (6/27; 22%) compared to AE (10/27; 37%).

CONCLUSIONS

Among physically inactive older adults, participation in yoga or AE was associated with beneficial effects on subjective wellbeing when compared to a non-active control group. Yoga was associated with fewer injuries and may be especially suitable for older adults (DRKS 00015093).

Effect of yoga on pulse rate and blood pressure among women

Objectives:

Change in the past few decades in human life style, nowadays international health organizations, i.e., World Health Organization are also focusing on prevention along with treatment aspect of chronic illness. Researches focus that women of age group 30–45 years are at increased risk for hypertension and heart disease due to increased weight. Yoga is an effective method to control our physiological variables like blood pressure (BP), pulse, etc. The main aim of this study was to identify the effects of yoga on physiological variables.

Methods:

The study was an experimental study with two group, pretest and posttest control group, design, which was conducted on 40 female participants. Pranayama and meditation for a period of 6 weeks was done by these women.

Results:

Yoga therapy significantly reduced the BP (0.000*) and pulse rate (0.000*) of women, which was also statistically proved.

Conclusions:

Yoga therapy can be an effective method to control BP and pulse rate of patients with chronic diseases.

Combined effect of daily physical activity and social relationships on sleep disorder among older adults: cross-sectional and longitudinal study based on data from the Kasama study

Background

This study investigated whether daily physical activity of older adults, combined with social relationships, is associated with the risk of sleep disorder. Further, it determined whether a high level of one variable with a low level of the other, leads to a significantly lower risk of sleep disorder than low levels of both.

Methods

The sample comprised 1339 community-dwelling older Japanese adults: 988 in Study 1 and 351 in Study 2. The level of daily physical activity and range of social relationships were assessed using the Physical Activity Scale for the Elderly and the Lubben Social Network Scale, respectively. The Pittsburgh Sleep Quality Index was used to assess sleep disorder. To test the combined relationships and effects in Studies 1 and 2, the medians for the respective scores of each of the following four groups that the participants were categorized into, were calculated: (1) low activity group with low social relationships, (2) low activity group with high social relationships, (3) high activity group with low social relationships, and (4) high activity group with high social relationships. After adjusting for potential confounders, a logistic regression analysis was conducted in Study 1. After adjusting for potential confounders, a Cox proportional hazards regression analysis was conducted in Study 2.

Results

Study 1 revealed that the high activity group with high social relationships showed a significantly lower risk of sleep disorder (ORs: 0.585, 95% CI: 0.404–0.847) than the low activity group with low social relationships. Study 2 also revealed that the high activity group with high social relationships showed a significantly lower prevalence of sleep disorder (HRs: 0.564, 95% CI: 0.327–0.974) than the low activity group with low social relationships.

Conclusions

Our findings suggest that for older adults with high social relationships, being physically active is favorably associated with sleep quality. However, a high level of one variable with a low level of the other has not been confirmed in improving sleep quality among older adults.

Study protocol for yoga-based lifestyle intervention for healthy ageing phenotype in the older adults (yHAP): a two-armed, waitlist randomised controlled trial with multiple primary outcomes

INTRODUCTION

The conceptualisation of healthy ageing phenotype (HAP) and the availability of a tentative panel for HAP biomarkers raise the need to test the efficacy of potential interventions to promote health in older adults. This study protocol reports the methodology for a 24-week programme to explore the holistic influence of the yoga-based intervention on the (bio)markers of HAP.

METHODS AND ANALYSIS

The study is a two-armed, randomised waitlist controlled trial with blinded outcome assessors and multiple primary outcomes. We aim to recruit 250 subjects, aged 60-80 years from the residential communities and old age clubs in Bangalore city, India, who will undergo randomisation into intervention or control arms (1:1). The intervention will include a yoga-based programme tailored for the older adults, 1 hour per day for 6 days a week, spread for 24 weeks. Data would be collected at the baseline and post-intervention, the 24th week. The multiple primary outcomes of the study are the (bio)markers of HAP: glycated haemoglobin, low-density lipoprotein cholesterol (LDL-C), systolic blood pressure, and forced expiratory volume in 1 s for physiological and metabolic health; Digit Symbol Substitution Test, Trail Making Tests A and B for cognition; hand grip strength and gait speed for physical capability; loneliness for social well-being and WHO Quality of Life Instrument-Short Form for quality of life. The secondary outcomes include inflammatory markers, tumour necrosis factor-alpha receptor II, C reactive protein, interleukin 6 and serum Klotho levels. Analyses will be by intention-to-treat and the holistic impact of yoga on HAP will be assessed using global statistical test.

ETHICS AND DISSEMINATION

The study is approved by the Institutional Ethics Committee of Swami Vivekananda Yoga Anusandhana Samsthana University, Bangalore (ID: RES/IEC-SVYASA/143/2019). Written informed consent will be obtained from each participant prior to inclusion. Results will be available through research articles and conferences.

Exercise in Aging: Be Balanced

The beneficial effects of exercise are recognized for preventing physical and cognitive decline during the aging process. However, there is still a gap concerning recommended intensity, volume, frequency and mode of exercise especially for older people. The aim of this study was to investigate an appropriate type of physical activity (PA) model for healthy aging. A commentary of the influence of PA and exercise on healthy aging through an online search of the databases Web of Science, PubMed and Google Scholar. Two living groups can be considered as potential references: modern hunter-gatherer small-scale population and master athletes. Greater physical activity is proposed for healthy aging than that recommended by WHO. Additionally, mindfulness meditation techniques during exercise are recommended especially for persons practicing long-duration exercises. Complex and compound exercise and workouts should include challenging exercises adjusted and balanced to provide clients, especially older people, with noticeable changes and progress.

Yoga for Healthy Aging: Science or Hype?

Yoga, one of the world’s oldest health systems is receiving new attention for claims that it can contribute to healthy aging. Until recently, scientific evidence for its efficacy has relied heavily on small and poorly-designed research, but this is changing. Multiple, well-designed studies provide data showing that yoga practice has positive effects on cellular aging, mobility, balance, mental health, and prevention of cognitive decline—all areas of concern for older adults. Since the cost of implementing yoga-based community and home-based interventions is low—policymakers are also eyeing yoga practice as a cost-effective way to reduce medical costs and improve outcomes among a growing aging population. This commentary reviews the evidence for both physical and mental health benefits from yoga, as well as concerns about injuries that have been associated with certain types of yoga practice. It reveals a surprising range of yoga programs and difficulty levels that provide opportunities for almost anyone to participate and gain health benefits with practice.

Older women and wellbeing through the pandemic: Examining the effect of daily online yoga lessons

The researcher reports the impact of online yoga lessons on a cohort of community-dwelling older adult women in mitigating fears, anxieties and promoting resilience, wellbeing and salutogenic wellness during the pandemic as compared to a control group. Online yoga lessons were effective and economic class, education, religion, marital status, and living arrangements were significant moderators. Intervention adherence had the strongest predictor effects. The combined effects of significant predictors were robust and latent class analyses indicated middle class, above threshold (>50%) lessons attendees and self-practice doers, single, living in nonstandard families, college educated, and Hindus, were likely to gain most.

Intensity and type of physical activity predicts depression in older adults

This study examined whether various levels of physical activity among older adults predicted levels of depression and whether there were racial differences in the levels and types of physical activities engaged in by adults aged 50 and older.

METHOD

Data from the 2015-2016 National Health and Nutrition Examination Survey (NHANES) were analyzed for 2,474 adults aged 50 years and older. Variables of focus were demographics, physical activity and depression, assessed using the Physical Activity Questionnaire and the Mental Health - Depression Screener.

RESULTS

There was a significant positive relationship between income and depression; individuals with higher income had lower levels of depression. Simple linear regression revealed income significantly predicted depression scores, b = -.20, F(1, 2296) = 96.35, p < .001, explaining 4% of the variance, R2 = .04. As age increased, all levels of physical activity declined, regardless of the category. Vigorous recreation-related activity and moderate recreation-related activity each made significant, unique contributions to depression scores.

CONCLUSION

Findings from the current study suggest that physical activity interventions should be culturally appropriate and tailored to the needs and abilities of individual older adults to maximize benefits and minimize adverse events, particularly among community dwelling older adults.
