| 摘 要： | 为揭示下肢运动性疲劳对纵跳的动力学特征的影响,22名男性体育教育专业大学生志愿参加了实验。结果表明,随着下肢负荷时间的增加纵跳的垂直方向分力和冲量下降,而左右、前后方向分力和冲量增加,三个方向的力矩随负荷时间的延长而增加。

| Abstract: | The purpose of this study is to identify the effect of sport fatigue of lower extremity on thekinetic characteristics of vertical jump. 22 male students majoring in PE acted as volunteers in the test.The result indicates that the component force and impulse in vertical direction decrease when lowerextremity load duration prolongs, while the component force and impulse increase in the right and left aswell as forward and backward directions, and the torque produced in these three directions increaseswith the prolonged duration. |
