【摘要】 运用运动力学的原理以及文献资料和专家访谈的方法,本文详细分析了上肢动作对单手肩上投篮出手速度的作用。结果表明:大臂保持水平和肘关节充分上抬是影响投篮飞行弧度的主要因素,手腕前屈和手指拨球决定着球体的水平飞行和旋转,伸臂举球同手腕前屈、手指拨球的相互作用决定着球体的出手角度。更多还原

【Abstract】 This article,applying the theories of athletic mechanics and methods of documentary analysis and expert interview,conducted a detailed analysis of effect of upper limb on shooting-speed of single-armed shooting technique.The results of this article indicated: upper arm’s keeping level and elbow joint’s rising adequately are the main factors affecting basketball shooting’s flight radian;wrist and fingers flexion determine ball’s level flight and rotation;the interaction of elbow’s rising and wrist and fingers flexion determine the angle of shooting.更多还原
