投掷实心球是以力量为基础,以动作速度为核心的运动项目。要想取得投掷实心球的好成绩,不仅要有力量,更要掌握技术技巧。影响实心球成绩的因素主要有三个:出手初速度、出手角度及出手高度,出手初速度是最重要的因素。实心球出手初速度主要是由最后用力投掷球的距离和时间决定,用力距离越大,时间越短,则初速度就越大。最佳出手角度在一定范围内随着出手初速度的增大而增大。出手高度相对稳定,取决
Throwing the solid ball is based on the strength, the speed of movement as the core sport. To get a good result of throwing a solid ball, not only have the strength, but also to master the technical skills. There are three main factors affecting the performance of solid ball: the initial shot speed, shot angle and shot height, the initial shot speed is the most important factor. The initial speed of the solid ball shot is mainly determined by the distance and time of the final hard throwing ball. The greater the force distance, the shorter the time, the higher the initial velocity. The best shot angle within a certain range increases with the initial velocity of shot increases. Shot height is relatively stable, depending on
