| 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). |
