| 摘 要： | 以国家队10名优秀男子跳板跳水运动员为研究对象,对其同一动作103b的助跑进行了运动学分析,结果表明:跨跳步缓冲动作是采用主动缓冲;主动缓冲动作与制动、主动缓冲与压板的不同程度分离,缓解了动作过程中肌肉工作特点要求的矛盾、降低了系统能量的损耗;长步型跨步有利于缓冲动作本身的分离,助跑后较高的水平动量是完成人体水平缓冲的保证,步长储备和水平速度是主动缓冲赖以实现的重要因素。

| Abstract: | The objects of research are 10 excellent springboard diving male athletes from the national team.The paper makes kinetic analysis on their run-up in the same motion.The result shows that the buffer of stride-jump step is the active buffer.It is separated from the brake and plate-pressing.In this way,athletes can ease the tension caused by the function type of the muscle.The long stride step can help isolate the buffer.The high horizontal momentum after the run-up can ensure the horizontal buffer.And the len... |
