【摘要】 以国家队10名优秀男子跳板跳水运动员为研究对象,在合理界定跨跳步时相的基础上,对其摆动肢体的运动特征进行分析。发现跨跳步的摆臂方式是直肘沉臂和屈肘升臂、跨跳步的摆腿是采用控膝摆髋技术来增大人体的压板力量、"快升臂"和"高提腿"有利于增大有效压板和腾空高度。同时分别得到了跨跳步自由肢体摆动与支撑腿蹬伸协调配合的具体运动学特征和控膝摆髋技术的具体运动学参数。更多还原

【Abstract】 10 elite springboard divers from national team are taken as research objects,and the paper does a kinematic analysis on their characteristics of swinging limbs based on proper time phase of stride step.The results show that excellent sank arms with straight elbows and raising arms with bendy elbows are proper way of swinging arms;that in stride-jump,swinging the thigh with a perfect fixed knee can increase the pressure on the springboard;that "rapid arm ascending" and "high leg lifting" are good for pressing springboard and increasing the flight height.At the same time,the concrete kinetic parameter on both the harmony between swinging the free bodies and stretching the sustaining leg and the technique of the swinging the thigh with fixed knee are gained.更多还原
