| 摘 要： | 通过对36名二级青少年男子篮球运动员双侧膝关节进行等速测试,探析青少年篮球运动员膝关节向心屈伸肌群的生物力学特性,为运动训练、科学选材及临床康复等提供理论依据.方法:利用 Kinitech等速康复肌力测试系统,对青少年男子篮球运动员膝关节屈伸肌群进行等速测试.结果表明:青少年男子篮球运动员双侧膝关节屈伸峰力矩随测试速度的增加呈递减趋势,且膝伸肌大于膝屈肌(P<0.05),峰力矩屈伸比(F/E)随给定测试速度的增加呈递增趋势;最大功率随测试速度的增大而增加,同一测试速度下屈、伸肌群最大功率无明显差异,左、右侧相比也无显著性差异(60°/s伸肌除外);屈伸肌群达峰力矩的角度(APT)表现为伸肌角度明显低于屈肌角度,随速度增加左右两侧膝关节达峰力矩的角度无显著差异;双侧膝关节屈伸肌群达峰力矩的时间(TPT)随测试速度的增加而减小,同一测试速度下伸肌达峰力矩的时间大于屈肌;右侧膝关节屈肌相对峰力矩(PT/BM)与下肢形态学指标表现出不同程度的正相关.本研究结论,青少年男子篮球运动员膝关节峰力矩变化规律与成年人相一致,但左右侧膝关节屈伸肌群做功能力发展不平衡,屈伸肌群运动达峰力矩角度、达峰力矩的时间存在显著差异.
