【摘要】 借助KS— 16mm高速摄影机 ,对我国第五届大学生运动会前 8名男子标枪运动员最后用力双支撑阶段的投掷动作进行了拍摄。研究结果 :把髋理解为“第二支撑制动环节” ,有助于对该环节的重视 ,更有助于了解其在最后用力过程中产生制动所发挥的作用。“第二支撑制动现象”的出现 ,对上肢的“鞭打”动作 (投掷效果 )有着直接的影响更多还原

【Abstract】 Ks-16mm high-speed camera was used to obtain the films of the movement of 8 javelin throwers in the period of double-support during their final exertion at the 5 th National University Games of the People’s Republic of China.The kinematics parameters were calcuated and analyzed by a film system.These data were processed with the very popular statistic software SPSS being used in the world,and the period was proved and evaluated the “phenomenon of the second support and brake”during the period of final exertion.The research results showed that the hip is the key in “joint of double support and brake”.The movement of the hip should be emphasized,and this idea is helpful to deeper our understanding of the function of the hip movement during the final exertion.The “phenomenon of the second support and brake”directly influence the “whip of upper limb”(the result of throwing).更多还原
