从站立位置开始的跳跃练习中，每步的跳跃距离随着步数的增加而增加。我们研究的假设，立场腿的关节动力学变量也将相应增加。11名男运动员（短跑和跳高运动员）进行跳跃练习，从双腿站立姿势开始，通过进行一系列的七次向前交替单腿跳跃来完成最长的距离。运动学和动力学数据通过运动捕捉系统和测力平台使用数据进行计算。第三步髋关节伸展运动减少（第一次：1.07±0.22，第三次：0.45±0.15，第五次：0.47±0.14 J·kg-1;部分η2：0.86），髋外展关节功率增加（第1步：7.53±3.29，第3步：13.50±4.44，第5步：21.37±9.93 W·kg-1;部分η2：0.58）;伸膝关节功率增加至第3步（1st：14.43±4.94，3rd：17.13±3.59，5th：14.28±2.86 W·kg-1;部分η2：0.29），踝跖屈关节功率增加（第1次：34.14±5.33，第3次：37.46±4.45，第5次：40.11±5.66 W·kg-1;部分η2：0.53）。这些结果与我们的假设形成对比，并表明，在跳跃练习中增加跳跃距离不一定伴随着站立腿关节动力学的增加。此外，关节动力学的变化在不同的关节和解剖轴上不同。
Jump distance per step in bounding exercises from the standing position increases with increasing number of steps. We examined the hypothesis that the joint kinetic variables of the stance leg would also increase accordingly. Eleven male athletes (sprinters and jumpers) performed bounding exercise, starting from the double-leg standing posture, and covered the longest distance possible by performing a series of seven forward alternating single-leg jumps. Kinematic and kinetic data were calculated using the data by a motion capture system and force platforms. Hip extension joint work were decreased at third step (1st: 1.07±0.22, 3rd: 0.45±0.15, 5th: 0.47±0.14 J•kg−1; partial η2: 0.86), and hip abduction joint power were increased (1st: 7.53±3.29, 3rd: 13.50±4.44, 5th: 21.37±9.93 W•kg−1; partial η2: 0.58); the knee extension joint power were increased until the third step (1st: 14.43±4.94, 3rd: 17.13±3.59, 5th: 14.28±2.86 W•kg−1; partial η2: 0.29), and ankle plantar flexion joint power increased (1st: 34.14±5.33, 3rd: 37.46±4.45, 5th: 40.11±5.66 W•kg−1; partial η2: 0.53). These results contrast with our hypothesis, and indicate that increasing the jump distance during bounding exercises is not necessarily accompanied by increases in joint kinetics of stance leg. Moreover, changes in joint kinetics vary at different joints and anatomical axes.
