摘要

The purpose of this study was discuss the biomechanical analysis of soccer volley shots on three ball-heights. Twelve junior amateur, right leg dominant, male soccer players (age=16.92±0.64 yrs; height=175.08±6.42 cm; weight=64.42±8.16 kg) participated in this study. Two high-speed video cameras (JVC DVL-9800) were used to record the kicking motion at 120 Hz. For calibrating the performance area, a digitizing system synchronized with an ATMI force plateform (2400 Hz) were used to collect the full-volley shots and side-volley shot performed at three kinds of ball heights. The difference between the biomechanical parameters with full-volley shots and side-volley shot performed at three kinds of ball heights were analyzed using LSD of repeat measure one-way ANOVA. The level of significance was set at 0.05. The results as follows: The ball velocity of full-volley shots and side-volley shots on lower ball-height had high value than that on higher ball-height. Soccer full-volley shots performed at three kinds of ball heights did not influence the peak ground reaction force and liner impulse before impact. The side-volley shots performed at higher ball height which required less front ground reaction force, and required more side and vertical ground reaction force before 30-45 degree approaching the ball. Beside that, As kicking the ball heights were elevated, side-volley shots required more ground reaction force to balance human actions.
