对于一个个人跳高运动员来说，很难确定进场跑结束时的水平速度和质心高度（分别为vh和H0）以及起跳阶段手臂的活跃度（AACT）的最佳值，因为它们取决于每个运动员抵抗起跳腿屈曲的能力。然而，最强的跳跃者通常是那些在起飞阶段（VZ1）结束时垂直速度值最大的人。因此，vz1可以作为一个跳高运动员抗屈曲能力的粗略指标。该项目推导出了允许使用跳高运动员测量的vz1值来预测VHO、H0和AACT的预期值的方程。将这些参数的预测值与实测值进行比较，有助于诊断个体跳跳者的技术缺陷。
It is difficult to ascertain for an individual high jumper the optimum values of the horizontal velocity and height of the center of mass at the end of the approach ran (VHOand H0, respectively) and of the activeness of the arms during the takeoff phase (AACT), because they depend on each athlete’s ability to resist buckling of the takeoff leg. However, the strongest jumpers will generally be those with the largest vertical elocity values at the end of the takeoff phase (VZ1). Therefore, VZ1may serve as a rough indicator of a high jumper’s ability to resist buckling. This project derived equations that permit the use of the measured VZ1value of a high jumper to predict what values should be expected for VHO, H0, and AACT. Comparison of the predicted and actual values of these parameters should help to diagnose the technique deficiencies of individual jumpers.
