摘要
以男伞兵为对象,借助高速摄影和仪器分析方法,对半蹲式和侧滚式两种姿势着陆时身体质心承受的冲击过载进行了比较研究。结果表明,从减小身体质心承受的冲击过载看,侧滚式优于半蹲式。
In this paper the impact load acting on the total body center of mass was studied. The subjects were three male parachuters who were young and healthy. The experiments performed in the laboratory under simulated parachute jumping and landing conditions were conducted by means of the high-speed photography and apparatus analysis. The experimental results showed that in terms of reducing the landing impact load acting on the total body center of mass, the side spin posture was better than the half-squat posture.
