| 摘 要： | 目的：以杨浦区150名40-69岁的健康运动女性作为研究对象，探讨中老年运动女性踝关节肌力的年龄变化特征。方法：实验于2005—03／05在上海体育学院体质测试中心完成测试。选择上海杨浦区150名身体健康的运动女性，按年龄分为3组：40-49岁组、50-59岁组、60-69岁组，每组50人。所有受试者在瑞士CoNTREX公司提供的Contrex肌力测试系统上进行踝关节60（°）／s的等速肌力测试。观察运动女性踝关节肌力的衰退特征。结果：受试者的踝关节屈肌最大力矩／kg、屈肌最大功率／kg与年龄呈负相关（r=-0．449，-0．451，P=0．002），且在0．01水平上相关具有高度显著性；踝关节伸肌最大力矩／屈肌最大力矩与年龄呈正相关（r=0．516，p=0．00）；女性在50-59岁期间，踝关节伸、屈肌力量随年龄增大而呈现迅速衰退的趋势，在60—69岁期间出现了伸、屈肌衰退的明显不平衡，屈肌快于伸肌。结论：中老年运动女性踝关节肌力的衰退具有明显的部位和年龄特征；女性在60—69岁期间进行适当的体育运动可以更为有效地延缓踝关节屈肌的衰老；强加对60-69岁期间女性踝关节屈肌力量的训练以缩小伸、屈肌间衰退的差异可能是预防跌倒的有效途经。
