短跑运动员下肢肌肉耐力的实验测试及特征参数力学模型的构建

The Experimental Fest on the Stamina Muscle Forces of Lower Extremity and the Struction on Biomechanical Model of Charactersitic Factor For Sprinters

对14名短跑运动员的下肢肌肉耐力进行了测试,并对所测的数据进行了数据拟合,进而构建了力学建模。结果表明:男子肌肉耐力的力学模型为F=2.02e-0.00235t(kN),而女子为F=1.66e-0.00313t(kN);男运动员比女运动员的力量峰值大,力量衰减系数小,表明男运动员的耐力要强于女运动员。

The stamina muscle forces of lower extremity of 14 sprinters were tested. The biomechanical model of its characteristic variables was established by a method of simulate annealing algorithm. It was shown that, the stamina equation of male is F=2.02e^-0.00235t（kN）, while that of female is F= 1.66e^-0. 00313t （kN） ; the stamina forces of male splinters are better than those of female because the male has with high maximum force with lower attenuation factor.
