女子举重运动员不同纵跳方式中生物力学参数与专项成绩的相关研究

Study of the Relationship Between Biomechanic Parameters and Specific Performance in Different Vertical Jumps of Female Weightlifter

采用5种不同的纵跳方式,对12名女子举重运动员髋、膝关节的角度、角速度等生物力学参数进行采集,所获数据和举重专项成绩进行相关分析。结果表明:不同纵跳方式中的纵跳高度和专项成绩都有不同程度的相关。其中60cm下落跳中的生物力学参数和专项成绩相关因素最多,尤其是下落后的纵跳高度和弹性能利用率和专项成绩高度相关,相关程度在0.8左右水平。根据以上相关分析结果提出一种针对举重运动员的肌肉快速力量和离心肌力的训练方法,即适宜高度为60cm的跳深练习。

With the angle,speed,etc.,biomechanic parameters of hip and knee joint,12 female lifters who adopted 5 different jump mode have been collected.Correlation analysis has been done between the collected data and specific performance.The result shows that different extent correlation between jump height in different mode and specific performance.In these correlations,biomechanic parameters in 60cm dropping jump have the most correlation factors.Especially elasticity energy utilizing rate and the height of dropping jump have the high extent correlation coefficient about muscle speediness strength and muscle strenght in allusion to female lifter with 60cm feasible height.
