Muscle strength is impaired in obese persons due to low physical activity, obesity-related modifications in muscle morphology and as a consequence of calorie regulation (where applicable). Previously decreased BMI and increased hand grip strength was reported following a short duration yoga intervention in obese adults.
The present comparative controlled study was conducted on two hundred and ninety seven obese adults (BMI ≥25 Kg/M) aged between 20 and 59 years, to determine the effects of nine months of yoga or nutrition advice on muscle strength and body composition. Participants were assessed for bilateral hand grip strength, leg and back strength, and body composition at baseline, after 3 months, 6 months and 9 months of yoga or nutrition advice. BMI-adjusted bilateral hand grip strength and leg and back strength were calculated.
In the linear mixed model analyses, there was a significant interaction effect of Time X Groups for (i) right hand grip strength (F = 9.297, p < 0.001), (ii) left hand grip strength (F = 14.469, p < 0.001), (iii) BMI-adjusted right hand grip strength (F = 9.954, p < 0.001) and (iv) BMI-adjusted left hand grip strength (F = 13.853, p < 0.001). Bonferroni corrected post-hoc analyses (p < 0.05; in all cases) showed a significant increase in (i) bilateral hand grip strength and (ii) BMI-adjusted right and left hand grip strength in the yoga group while a decrease in (i) bilateral hand grip strength and (ii) BMI-adjusted right and left hand grip strength in the nutrition advice group.
Yoga practice appears to protect and increase upper limb muscle strength in obese adults.
由于体力活动水平低、与肥胖相关的肌肉形态改变以及热量调节（在适用的情况下），肥胖者的肌肉力量会受损。先前的研究报告称，肥胖成年人进行短期瑜伽干预后，体重指数（BMI）降低，手握力增强。
本研究采用对照试验设计，纳入 297 名年龄在 20 至 59 岁之间的肥胖成年人（BMI≥25 Kg/M），以确定瑜伽或营养建议对肌肉力量和身体成分的影响。在基线、3 个月、6 个月和 9 个月时，评估参与者的双侧手握力、腿部和背部力量以及身体成分。计算 BMI 调整后的双侧手握力和腿部及背部力量。
在线性混合模型分析中，时间与组之间存在显著的交互效应，具体表现为：（i）右手握力（F=9.297，p<0.001）、（ii）左手握力（F=14.469，p<0.001）、（iii）BMI 调整后的右手握力（F=9.954，p<0.001）和（iv）BMI 调整后的左手握力（F=13.853，p<0.001）。Bonferroni 校正后的事后分析（p<0.05；所有情况下）显示，瑜伽组的（i）双侧手握力和（ii）BMI 调整后的右手和左手握力均显著增加，而营养咨询组的（i）双侧手握力和（ii）BMI 调整后的右手和左手握力均显著降低。
瑜伽练习似乎可以保护和增强肥胖成年人的上肢肌肉力量。
