| Abstract: | The pictures of the jerk techniques of nine female weightlifting champions (including seven world record holders andone world championship medalist) were taken at the 11th Asian Games held in Beijing by synchronous filming with twoPHOTO-SONICS 1PL 16mm high speed cameras.Through the analysis and comparison of the three dimensional films,wefound that there were dffferences between female and male weightlifters in jerk techniques.The raising distance of the barof female weightlifters exceeded the normal range,which resulted in the greater distance in downward movement and morewaste of power.This showed that female weightlifters had greater potential for improvement.Compared with maleweightlifters,the speed of initial knees bend and jerk of female weightlifters was faster,producing a better performance.We also found that the optimum knee joint angle of first pull and the range of angle movement not only depended on thefunctional status of the knee muscle,but also closely related to the whole body and the total weight load. |
