罚球技术是篮球基本技术中非常重要的一项,罚球技术不单纯是一种手感,更重要的是球员心理对这项技术要有一个量的概念,出手速度、出手角度以及球的飞行轨迹与罚球是密切相关的。通过本文的分析研究发现,罚篮时球运行轨迹抛物线的高与低取决于出手时的力量的大小和用力的方向以及球的出手角度、速度,对此进行定量定性分析,对以后的教学和训练将会有很大的帮助。 Free throw technology is a very important basketball basic technology, free throw technology is not simply a feeling, more importantly, the player psychology of the technology to have a volume concept, shot speed, shot angle and the ball’s flight path and Free throws are closely related. Through the analysis and research of this article, it is found that the high and low parabolas of the ball trajectory when shooting a free throw are determined by the size of the force and direction of the shot and the shot angle and speed of the ball, and the qualitative and quantitative analysis of the trajectory parabola. Training will be of great help.
