    摘要: Our purpose was to evaluate the vertical ground reaction force, impulse, moments and powers of hip, knee and ankle joints, contact time, and jump height when performing a drop jump from different drop heights based on the percentage of a performer's maximum vertical jump height (MVJH). Fifteen male Division III athletes participated voluntarily. Eleven synchronized cameras and two force platforms were used to collect data. One-way repeated-measures analysis of variance tests were used to examine the differences between drop heights. The maximum hip, knee and ankle power absorption during 125 % MVJH and 150 % MVJH were greater than those during 75 % MVJH. The impulse during landing at 100 % MVJH, 125 % MVJH and 150 % MVJH were greater than 75 % MVJH. The vertical ground reaction force during 150 % MVJH was greater than 50 % MVJH, 75 % MVJH and 100 % MVJH. Drop height below 75 % MVJH had the most merits for increasing joint power output while having a lower impact force, impulse and joint power absorption. Drop height of 150 % MVJH may not be desirable as a high-intensity stimulus due to the much greater impact force, increasing the risk of injury, without increasing jump height performance.
