一、前言: 投掷链球,从持球到球离手需要3～4圈旋转。所以掷链球时,为正确地掌握人体和球一连贯地运动,不仅要从侧面观察,还须从运动者的上方进行观察、分析是很重要的。对受试者的动作,过去只采用从侧面的分析,从来没有过上方的研究。由此,本研究对受试者用16mm胶卷,分析受试者的动作和球的轨迹来说明掷链球的生物侧定学的特征。二、方法: 1.受试者: 本研究挑选了一名日本链球记录保持者,年龄,身长、体重及1982年的最高记录(表一)。他的掷链球方法是左旋转4圈的投掷法。
First, the foreword: Throw the hammer, from the ball to the ball to leave 3 to 4 lap rotation. Therefore, when throwing the hammer, in order to correctly grasp the human body and the ball in a consistent manner, it is important not only to observe from the side but also to observe and analyze from the top of the athlete. The behavior of the subject, the past only used from the side of the analysis, has never been the top of the study. Thus, the present study illustrates the bio-lateral pedigree characteristics of hammer throwers using 16 mm film, analyzing the subject’s movements and ball trajectories. Second, the method: 1. Subjects: This study selected a Japanese hammer throwing record holder, age, height, weight and highest record in 1982 (Table I). His method of throwing a hammer is a four-turn throwing method.
