摘要

This study investigated the biomechanical factors involved in Wushu side-stamp. Data were obtained from seven subjects of the National Wushu Teams in Taiwan (age: 28.0±5.2 yr, height: 175.0±4.6 cm, weight: 72.1±6.6 kg, practice time: 9.0±2.4 yr). The biomechanical factors of the side-stamp were analyzed with AcqKnowledge Bio-pac system (2000Hz) and high-speed Redlake MotionScope Cameras (250Hz). The results through Pearson's product-moment correlation indicated that the movement time of the side-stamp was increased by increasing the time period between the time starting to extend the knee angle of the kicking leg and the time making contact with the target (p＜.05). The knee angle of the supporting leg was increased by decreasing the movement time (p＜.05). The punching effect was increased by decreasing the knee angle of the supporting leg in making contact with the target (p＜.05) and by increasing the knee angle of the supporting leg in the action phase (p＜.05). To sum up, the effect of the side-stamp resulted from the kicking after contacting the target, rather than from the muscle momentum before the contact. For shortening the movement time and improving the striking effect of the side-stamp, one should enlarge the stretching of the supporting leg. Besides, the time initiating the extension of the kicking leg should be closed by the time hitting the target.
