本文采用解析法与运动生物力学等研究方法,指出用起跳时间、水平速度损失率两项指标评价起跳效果的不足,提出了蹬伸时间指数和水平速度转化率两项新的综合指标,并对新指标的应用进行了分析。
In this paper, analytical method and kinematic biomechanics are used to study the shortcoming of jump-off time and horizontal speed loss rate. Two new comprehensive indexes of kick-on time index and horizontal speed conversion rate are put forward. The application of the new indicator has been analyzed.
