Abstract

Background: There is increasing evidence that practicing tai chi or yoga can improve the elderly’s physical performance. This study aimed to compare the effects of tai chi and yoga on balance and leg muscle strength in the elderly. Material & Methods: This cross-sectional study involved 90 elderly persons who practice tai chi (n = 36), yoga (n = 23), and a control group (n = 31). The balance function was assessed using the single-leg stance (SLS) test, while leg muscle strength (LMS) was assessed using a leg-back dynamometer. A Chi-square, Spearman rank test, one-way ANOVA with LSD post hoc were applied. The significance was set at p<0.05. Results: One-way ANOVA showed a difference in LMS and SLS between groups (p<0.01). LSD post hoc analysis found the difference in LMS between tai chi and yoga (64.3 vs. 41.5, p<0.01) and tai chi and control (64.3 vs. 30.4, p<0.01). The difference was also found in SLS between tai chi and control (36.7 vs. 6.2, p<0.01) and between yoga and control (41.4 vs. 6.2, p<0.01). Conclusion: Elderly persons who participated in tai chi and yoga demonstrated higher LMS and SLS performance than the sedentary participants. The tai chi group showed better muscle strength than the yoga group.

太极拳和瑜伽对老年人平衡和腿部肌肉力量的比较:一项横断面研究

背景:越来越多的证据表明，练习太极拳或瑜伽可以改善老年人的身体机能。这项研究旨在比较太极拳和瑜伽对老年人平衡和腿部肌肉力量的影响。材料与方法:这项横断面研究涉及90名老年人，他们练习太极(n = 36)，瑜伽(n = 23)，对照组(n = 31)。使用单腿站立(SLS)测试评估平衡功能，使用腿背测功仪评估腿部肌肉力量(LMS)。采用卡方检验、Spearman秩次检验、单因素方差分析和LSD事后检验。p<0.05为显著性。结果:单因素方差分析显示两组间LMS、SLS差异有统计学意义(p<0.01)。LSD事后分析发现，太极组和瑜伽组的LMS差异(64.3比41.5,p<0.01)，太极组和对照组的LMS差异(64.3比30.4,p<0.01)。太极组和对照组的SLS(36.7比6.2,p<0.01)和瑜伽组的SLS(41.4比6.2,p<0.01)也存在差异。结论:参加太极和瑜伽的老年人LMS和SLS的表现高于久坐不动的老年人。太极拳组比瑜伽组表现出更好的肌肉力量。
