力量漸增式、彈震式與功能性等長式阻力訓練法之運動學與動力學比較

The purpose of this study was to investigate the differences of kinematics and kinetics in three different movements such as, slow ramp movement (SRM), ballistic movement (BAM) and functional isometric movement (FIM). Sixteen male taekwondo athletes completed three trials for each movement with 3 min rest between each trial. 30% of subject's previously determined 1 RM was chosen as a testing load. A goniometer was attached on the joint of levers to measure the range of concentric phase during testing movement. The displacement of weigh stack was measured by UD-300 displacement sensor that was installed above the weigh stack. Load cell was connected with cable of machine to measure the pulling force. The results indicated that the kinematics was significantly greater during FIM and BAM compared to SRM for contraction time and average velocity. The kinetics was significantly greater during BAM and FIM compared to SRM for peak force and average force. Moreover, BAM has significant higher average force than FIM. Thus, the results of this study may reveal that BAM is the best form of resistance training for developing explosive strength.
