一、前言在掷链球时,链球出手前,要通过3圈或4圈的旋转,因而,在投掷链球时,为了精确地掌握人体与球的一系列运动,不仅要从侧面,也有必要从运动者的上方进行观察分析。过去有关投掷链球的研究中,虽然对球进行了从侧方和上方的分析,但对受试者一直是从侧面进行分析,未见有从上方的分析。因此,本研究拟根据拍摄的16mm胶片,从受试者的侧方和上方,分析受试者的动作和球的运动轨迹,以说明掷链球的生物力学特征。
I. INTRODUCTION In hammer throwing, before the hammer throws, it must pass three or four revolutions. Therefore, in order to accurately grasp a series of movements of the human body and the ball when throwing the hammer ball, it is necessary not only from the side but also from the movement The top of the observation and analysis. In the past research on throwing the hammer, although the ball was analyzed from the side and above, the subjects were always analyzed from the side and no analysis from above was found. Therefore, this study intends to analyze the motion of the subject and the trajectory of the ball from the side and the top of the subject based on the filming of 16 mm film to illustrate the biomechanical characteristics of the hammer ball.
