| 摘 要： | 老年人神经肌肉结构和功能发生一系列变化，主要表现为骨骼肌老龄性萎缩，肌肉力量下降和运动单位减少。老年人内分泌的改变也不利于肌肉代谢，其主要特征有血清睾酮总量、血清游离睾酮和血清生长素下降，而血清皮质醇上升。这些衰老征象影响了老年人的日常生活，但力量训练可以有效地增加老年人肌肉质量和力量，改变肌纤维百分比，也能引起内分泌产生适应性变化。

| Abstract: | In the neuromuscular system of the senior,there is a series of structural and functional changes,including age-inducing muscle atrophy,muscle strength decline and motor units decrease. The change of endocrine,is not in favor of the senior muscle metabolism,in which the amount of total serum testosterone and growth hormone continually decreases,whereas the amount of cortisol increases. These aging signs bring the senior inconvenience in their daily life. However,strength exercise can effectively improve muscle mass and strength,alter percentage of muscle fiber and cause endocrine adaptive changes. |
