The goal was to review systematically the comparative effectiveness of yoga, compared with other exercise interventions, for older adults as shown on measures of health and physical functioning.
This was a systematic review with both narrative synthesis and meta-analysis.
Searches were conducted in MEDLINE®/PUBMED, PSYCINFO, CINAHL, Web of Science, and SCOPUS; bibliographies of selected articles; and one systematic review on the effects of yoga on cardiovascular disease.
Original studies from 1950 to November 2010 were sought, evaluating the effects of yoga on older adults. The search was restricted to randomized controlled trials of yoga in subjects ≥age 60, and published in English. Data were extracted and evaluated regarding setting, population size and characteristics, intervention type and duration, comparison group, outcome assessment, data analysis, follow-up, key results, and the quality of each study according to specific predetermined criteria.
The search yielded 18 eligible studies (N=649). The studies reported on older adults across a range of settings, intervention intensity, and outcome measures. The majority of the studies had<35 participants (range 9-77). Quantitative and qualitative synthesis of the studies suggested that the benefits of yoga may exceed those of conventional exercise interventions for self-rated health status, aerobic fitness, and strength. However, the effect sizes were modest, and the evidence was mixed for yoga's effect on depression, sleep, and bone-mineral density. Studies did not find an effect on cognition.
Small studies with mixed methodological quality suggested that yoga may be superior to conventional physical-activity interventions in elderly people. The precision of the estimates remains low. Larger studies are necessary to define better the intersection of populations, settings, and interventions in which yoga is most beneficial.
系统评价瑜伽与其他运动干预措施相比对老年人健康和身体功能的比较效果。
这是一项系统评价，包括叙述性综合和荟萃分析。
在 MEDLINE®/PUBMED、PSYCINFO、CINAHL、Web of Science 和 SCOPUS 中进行了搜索；选择文章的参考文献；以及一项关于瑜伽对心血管疾病影响的系统评价。
从 1950 年到 2010 年 11 月，我们寻找了评估瑜伽对老年人影响的原始研究。搜索仅限于≥60 岁的瑜伽受试者的随机对照试验，并以英文发表。根据具体预定的标准，就研究的设置、研究对象的数量和特征、干预类型和持续时间、对照组、结果评估、数据分析、随访、关键结果以及每项研究的质量等方面提取和评估数据。
搜索结果得到 18 项符合条件的研究（N=649）。这些研究报告了各种环境、干预强度和结果测量的老年人。大多数研究的参与者<35 人（范围 9-77 人）。对这些研究的定量和定性综合表明，瑜伽的益处可能超过传统运动干预对自评健康状况、有氧运动能力和力量的益处。然而，效果大小适中，瑜伽对抑郁、睡眠和骨矿物质密度的影响证据不一。研究没有发现瑜伽对认知的影响。
小样本量且方法学质量参差不齐的研究表明，瑜伽可能优于老年人的常规身体活动干预措施。估计的精度仍然较低。需要更大规模的研究来更好地确定瑜伽最受益的人群、环境和干预措施的交叉点。
