| Popis: | 90 The purpose of this study was to examine the differences of snatch movement among five female weight lifting athletes snatch movement in kinematics parameters. Lifters’ knee joint angle were measured in snatch movement success and failure conditions. A JVC Dv9800u video camera was used to onecord their movement. The video camera was located at the right side of the podium at 7.3 meters distance. After collecting the data, Ariel Performance Analysis System（APAS）software was used to analyze the data. The velocity in the phase of bringing up in Yi-Han, Guo and Shi-Jun, Huang were fast, so that increased the deviation of barbell. which caused horizontal velocity of barbell in sinking phase were too fast, and increased the difficulty of taking the barbell. We suggest that Yi-Han, Guo and Shi-Jun, Huang should modify the knee angle before bringing up phare--it means to lower the position of hips and to add the distance between leg and the barbell. Feng-Ying, Li Su-Hua, Xie and Xiao-Lian Chen used more force in arms to control the deviation of barbell in the phase of bringing up, which slow down the vertical velocity of barbell. We suggest that Feng-Ying, Li Su-Hua, Xie and Xiao-Lian Chen should modify the knee angle before bringing up phare--it means to raise the position of hips and to shorten the distance between leg and the barbell, and to reduce the unnecessany force that was wasted away. |
