投篮时下肢发力的重要性及其生物力学分析

The Importance of Lower-Limb Exerting Force in Shooting and its Biomechanical Analysis

出手用力时的下肢发力是投篮过程中的一个重要环节,是投篮力量的主要来源之一。下肢适宜的发力是投篮时上肢协调、自然完成动作的保证,有利于手对球的控制,能够在一定程度上提高投篮命中率。本文将从生物力学角度,对投篮时下肢发力遵循的基本原理、发力动作的基本形式及其对投篮力量、出手速度、出手角度的影响进行论述。

WTLower limb exerting force is an important link in shooting and is the main source of shooting strength. It guarantees the coordination of the upper limb and the accomplishment of the action, and it is good for the player to control the ball and improve the shot rate to some extent. This paper, from the angle of biomechanics, elaborates the basic principle、its basic action form of the lower limb force-exerting as well as its influence onshooting strength、hands-off speed and angle.
