Performance of a vertical jump was analyzed with respect to the contribution of the different body segments to the forces acting on the whole body center of gravity. Both cinematograph and force-platform techniques were employed. The data disclosed that the take-off velocity in vertical jumps was caused by the different components as follows: knee extension 56%, plantar flexion 22%, trunk extension 10%, arm swing 10%, and head swing 2%. However, the average take-off velocity of the total performance (3.03 m/s) was only 76% from the theoretical maximum calculated from the segmental analyses. Optimal timing of the segmental performances was calculated to increase this "efficiency" to 84%. Great variance were observed among individuals in the total performance despite the similarities in utilization of the performance of individual segments.
针对不同身体节段对作用于全身重心的力的贡献，对垂直跳跃的表现进行了分析。采用了电影摄影技术和力平台技术。数据显示，垂直跳跃中的起跳速度由以下不同部分引起：膝关节伸展56%、跖屈22%、躯干伸展10%、手臂摆动10%以及头部摆动2%。然而，整体表现的平均起跳速度（3.03米/秒）仅为根据节段分析计算出的理论最大值的76%。计算得出节段表现的最佳时间，可将这种“效率”提高到84%。尽管在各个节段表现的利用上存在相似性，但个体之间在整体表现上仍观察到很大差异。
