摘要:
      摘要 目的:观察太极拳训练对老年人下肢骨骼肌肌力影响的特点及趋势。 方法:根据纳入和排除标准,选取年龄在60岁及以上的北京社区老年人。选取长期太极拳训练者205人,同时采取随机整群抽样方法,进行配对选取非太极拳训练者205人。用手持式测力计,测量双侧髂腰肌、股四头肌、腘绳肌、胫前肌的最大等长肌力。 结果:太极拳训练组髂腰肌、股四头肌、腘绳肌和胫前肌的肌力均高于非太极拳训练组,其差异有显著性意义(P<0.05)。太极拳训练对髂腰肌肌力增加作用较其他三组肌力显著(P<0.05)。随年龄增长,非太极拳训练组老年男性下肢四组肌力下降明显,从60—89岁的30年间下降率34.40%—38.99%。女性三组肌力的下降率为14.26%—26.25%,除股四头肌外。男性下肢肌力的下降较女性快。太极拳训练组,男性髂腰肌在60—69岁、70—79岁和80—89岁各组肌力/体重的比值分别为:2.53N/kg、2.94N/kg、2.59N/kg,股四头肌在各年龄组中分别为:1.73N/kg、1.98N/kg、1.83N/kg,腘绳肌在各年龄组中分别为:1.73N/kg、1.85N/kg、1.75N/kg,胫前肌在各年龄组中分别为:1.91N/kg、2.12N/kg、1.94N/kg,并没有随年龄增长呈下降趋势,女性也呈现同样的趋势。 结论:太极拳训练组下肢四组肌力均高于非太极拳训练组,且没有随年龄增长呈下降趋势。在髂腰肌、股四头肌、腘绳肌和胫前肌四组肌力中,太极拳对髂腰肌的作用最为显著。

Abstract:
      Abstract Objective: To observe the characteristics of age-related deterioration of muscle condition among taijiquan training practitioners. Method: According to inclusion and exclusion criteria, 205 long-term taijiquan training(TC) practitioners, aged over 60 years. According to the random cluster sampling method, four communities were selected, 205 age-match non-TC (NTC) controls were enrolled in this study. The maximum isometric strength of iliopsoas, quadriceps femoris, hamstrings and tibialis anterior were measured in two groups by hand-held dynamometer. Result: The strength of iliopsoas, quadriceps femoris, hamstrings and tibialis anterior in TC group were significantly stronger than that in NTC group (P<0.05). The effect of TC on iliopsoas strength was more than other three other muscle strength. The strength of the lower limbs in male NTC declined sharply with advancing ages. The muscle strength declined progressively about 34.40%—38.99%. This phenomenon was seen during the iliopsoas, hamstrings and tibialis anterior, except for quadriceps femoris. In female the muscle strength declined progressively about 14.26%—26.25%. The ratio of iliopsoas, quadriceps femoris, hamstrings, tibialis anterior muscle strength/weight in different age groups of male TC participants was 2.53N/kg, 2.94N/kg, 2.59N/kg; 1.73N/kg, 1.98N/kg, 1.83N/kg; 1.73N/kg, 1.85N/kg, 1.75N/kg; 1.91N/kg respectively, 2.12N/kg, 1.94N/kg. The strength of lower limbs did not decreased significantly with aging in the male and female TC group (P>0.05). Conclusion: The strength of iliopsoas, quadriceps femoris, hamstrings and tibialis anterior in TC group were significantly stronger than that in NTC group, especially for iliopsoas. The muscle strength of lower limbs in TC participants did not decline with the increases of the ages.
