In this paper the impact force acting on the total body's mass center was studied. The subjects were three young, healthy male parachuters. The experiments performed in the laboratory under simulated parachute jumping and landing condition were analyzed by highspeed photography and apparatus. The experimental results showed that:(1)when the subjects jumped from the platform 1.0 or 1.5m high, the vertical impact force sustained by the total body's mass center with the half-squat posture was larger than that with the side spin posture. (2)when the subjects jumped from the platform of 1.5 m high, the total body's mass center gained a horizontal impact force risen by the half-squat posture larger than that risen by the side spin posture. When the subjects jumped from the platform of, 1.0 m high, the horizontal impact, force produced by both of the above mentioned postures seemed to be the same, which needs further investigation. (3) the side spin posture was better than the half-squat posture for reduce the landing impact force on the total body's mass center.

本文用高速摄影和仪器分析方法,研究了男性伞兵用平台训练模拟跳伞着陆时,用半蹲式和侧滚式两种姿势人体质心承受的冲击力。实验结果表明:<1>当平台高度为1.0和1.5米,用半蹲式着陆人体质心承受的冲击力大于用侧滚式姿势着陆;<2>人体质心承受的垂直冲击分力。也是半蹲式大于侧滚式;<3>当平台高度为1.5米时,半蹲式着陆使人体质心承受的水平冲击分力大于侧滚式;但平台高度为1.0米时,两种姿势产生的值均有消涨,相互交叉,有待进一步研究。因此,从减小人体质心承受的冲击力看,选用侧滚式着陆优于半蹲式。
