| 摘 要： | 为了探索起跳后人体空中姿态对摸高成绩的影响,用中国模型对一名男子运动员用不同的空中姿态进行摸高模拟。结果表明:空中姿态对摸高成绩有影响;摸高成绩以单手上举,双脚直腿下落为最高,而以双手上举,双脚直腿上提为最低,两者的差值为22.98cm。姿态对摸高的影响幅度占摸高成绩的7%左右;在对摸高成绩的影响幅度上,下肢的升降作用比上肢要大得多。

| Abstract: | In order to explore the affection of different body postures on reaching height in the air,the jumps in different postures of a male athlete were simulated with Chinese Model.It was shown that the different postures had some affection on the reaching height.highest reaching height could be achieved when the subject was in the posture of stretching lower extremities with the upper extremity up.The reaching height was the lowest when the athlete stretched lower extremity straightly with upper extremities up.The difference between the highest and the lowest was about22.98cm,which was about7%of the total jump height.In the extent of affection,the lower extremity seemed to be greater than the upper extremity. |
