中文摘要:

定距离原地投篮的弧线轨迹主要取决于出手速度和出手角度。为了探究优秀青年男子运动员不同距离原地投篮命中率的各影响因素，采用平面定机高速摄影和运动技术解析法，采集12名U16中国国家男子篮球运动员罚篮、中投和三分投球中篮过程投篮手臂的腕、肘、肩、膝等相关关节的线速度和角速度等参数，运用关联度和回归分析(Matlab2018a)探究规律。发现8项因素对原地投篮对命中率有不同程度的影响，其中，球初始高度、球离手高度、腕关节速度和膝关节速度4项因素，通过投篮角度和投篮速度对不同距离投篮中命中率的影响最大。

英文摘要:

The trajectory of fixed distance set shot mainly depends on shooting speed and shooting angle. The paper collects parameters of the linear velocity and angular velocity of the wrist, elbow, shoulder, knee and other related joints of the shooting arm among twelve U16 national male basketball players in the process of free throws, medium shots and three-point shots with plane high-speed photography and sports technique analysis to explore the factors affecting the shooting percentage in different distances through the shooting angle and shooting speed. It uses correlation and regression analysis (Matlab2018a) to obtain the factors affecting shooting parameters. The results show that eight factors have exerted different degrees of impacts on the shooting percentage in the standing shots, among which the initial height, off-hand height, wrist joint velocity and knee joint velocity have the great impacts on the shooting percentage in different distance shots through shooting angle and shooting speed.
