The primary purpose of this study was to identify exemplary basketball shooting mechanics to devise an effective and efficient training method for successful basketball shooting. Motion data of basketball shots by 10 recreational players and 10 college athletes at three different distances (3.2 m, 5 m, 6.8 m) were collected using 13 cameras (240 Hz). The present study quantified the upper extremity joint coordination using the vector-coded Coupled Angular Variability (CAV). Recreational players exhibited higher CAV at 6.8 m (Median P50 = 16.947), whereas college athletes exhibited higher CAV at 5 m (Median P50 = 18.487). The primary focus of arm coordination patterns was on shoulder joint coordination during the preparation phase, with higher coordination variability associated with greater shot accuracy. Recreational athletes straightened their shoulder and elbow joints simultaneously when performing a basketball shot. In contrast, collegiate athletes showed variations primarily resulting from proximal coordination patterns, leading to a larger range of motion (ROM) for elbow joint flexion and extension. This finding could fundamentally alter how shooting is practiced.
本研究的主要目的是确定模范的篮球投篮技术，以设计一种有效且高效的成功篮球投篮训练方法。使用13台摄像机（240赫兹）收集了10名业余球员和10名大学运动员在三个不同距离（3.2米、5米、6.8米）的篮球投篮动作数据。本研究使用矢量编码耦合角变异性（CAV）对上肢关节协调性进行了量化。业余球员在6.8米处表现出更高的CAV（中位数P50 = 16.947），而大学运动员在5米处表现出更高的CAV（中位数P50 = 18.487）。手臂协调模式的主要重点是准备阶段的肩关节协调性，协调性变异性越高，投篮准确性越高。业余运动员在进行篮球投篮时同时伸直肩关节和肘关节。相比之下，大学生运动员的变化主要源于近端协调模式，导致肘关节屈伸的运动范围（ROM）更大。这一发现可能会从根本上改变投篮训练的方式。
