| 摘 要： | 目的:研究1 km自行车竞速赛加速度与踝关节肌肉力学特征之间的关系,更好地为自行车局部力量训练提供理论基础。方法:选择6名青少年自行车运动员进行1 km场地自行车竞速、等速运动、表面肌电图测试,对实验数据进行相关、主因素及回归分析等统计学处理。结果:1)作Friedman秩次分析不同角度下EPT、FPP、EAP、FAP、EDLM、GM及EDLM/EPT、GM/FPT差异显著(P<0.05),因子分析得2个主因素;2)AA1与1 km成绩,EPT,EAP、FAP及60°/s、90°/s下EDLM显著相关(P<0.05);3)以AA1为因变量经三步多元回归得到3个自变量,分别是EAP120°/s,EPT120°/s,EPT90°/s。结论:1)第1圈平均加速度与1 km成绩、踝关节伸屈肌EPT、EAP、FAP及60°/s、90°/s下伸肌iEMG高度相关;2)自行车运动员踝关节伸屈肌素质可以归纳至两个主要成分,第一是伸肌肌群的提拉作用,第二是伸屈肌肌群平均功率及相互协调作用;3)以踝关节周围肌肉群素质概括首圈加速度,90°/s、120°/s角速度模式下伸肌做功及力矩是重要决定指标,在自行车的训练中应该注重伸肌素质... |
