A study for musculo-tendon coordination related to various jumping movements using computer simulation.

对篮球防守中需要快速和高水平表现的跳跃动作进行了生物力学研究。研究结果表明：1)被试在不要求跳得不高的情况下，最好从蹲姿跳起，双臂举高；2)在要求跳得最大高度的情况下，最好从蹲姿跳起，双臂举低。在任何情况下，它揭示了后卫必须使他们的身体蹲下时，他们必须跳得又快又高。进行了一项生物力学研究，研究了在有和没有跳跃前运动的情况下，使用足步的中外侧到达运动。本研究结果表明，在预跳条件下的总到达时间（TRT）明显短于没有预跳动作的TRT。TRT的减少是由于步进时间（从运动开始到踏腿着地的时间）的减少，而不是由于反应时间（从视觉刺激到运动开始的时间）和到达时间（从踏腿着地到开始触摸目标的时间）的减少。

A biomechanical study was performed investigating jumping movements used in basketball defense requiring quick and high performance. The results of the study suggested that 1)subjects had better to jump from squatting position with their arms high when they are not required to jump not so high and 2) they should jump from squatting position with their arms low when they are asked to jump in maximal heights. In any case, it was revealed that defenders must set their bodies squatting when they must jump both quickly and highly.A biomechanical study was performed investigating medio-lateral reaching movements using foot step with and without pre-jump movements. The results of the present study showed that the total reach time (TRT) in the pre-jump condition was significantly shorter compared to the TRT without pre-jump movements. The decrement in the TRT was due to the decrease in the step time (time from the movement onset to the touch down of the step leg), not due to the response time (time from the visual stimulation to the movement onset) and the reach time (time from the touch down of the step leg to the onset of the touch to the target).
