The aims of this study were to evaluate movement patterns of topspin forehand, to define the main principles of performing this shot, and to determine the essential differences in individual types of topspin forehand. In total, 10 female high-level athletes participated in this study. The BTS analysis system was used with a novel model for the range-of-motion measurement. An acoustic sensor was attached to the racket for identification of a ball-racket contact. Players, performing topspin forehand, attempt to achieve maximal racket velocity based on the principles of proximal-to-distal sequences and summation of speed with a stretch-shortening character of cycle. The essential differences between type of topspin forehand occurred in the range of motion. Increased power of topspin shot was accompanied by a significant increase in range of motion in most of the studied joints and body segments, in particular in the rotation movement of the upper body, pelvis and shoulders, flexion and rotation in the shoulder and elbow joints, and flexion and rotation in knee joints.
本研究的目的是评估上旋正手击球的动作模式，确定执行此击球动作的主要原则，并确定不同类型上旋正手击球的本质差异。共有10名女性高水平运动员参与了本研究。使用BTS分析系统和一种用于测量运动范围的新型模型。在球拍上安装了一个声学传感器，用于识别球与球拍的接触。进行上旋正手击球的球员试图根据近端到远端的顺序原则以及具有拉长-缩短周期特征的速度总和来实现最大球拍速度。上旋正手击球类型之间的本质差异出现在运动范围内。上旋击球力量的增加伴随着大多数研究关节和身体部位运动范围的显著增加，特别是在上半身、骨盆和肩部的旋转运动、肩关节和肘关节的屈伸和旋转以及膝关节的屈伸和旋转方面。
