乒乓球反手台内侧拧技术的力学原理

Mechanic principle of backhand inside twists technique in table tennis

乒乓球反手台内侧拧技术运用“S”型引拍和“し”式的挥拍轨迹有利于增加球拍击球的瞬时速度和制造丰富的旋转。从力学的角度对乒乓球反手台内侧拧新技术进行了深入的分析和研究,探讨乒乓球反手台内侧拧技术的可行性和合理性,对进一步认识和改进此项技术有重要的现实意义。

The table tennis technique that lateral twist with backhand in an table making use of the ＂S＂ type to swing the racket in advance and ＂し＂ type of swinging track contributes to raising the instantaneous speed of racket hitting the ball and making plenty of rotation. This paper carries on deep analysis and study to this technique that lateral twist with backhand in the table in terms of mechanics, probes into feasibility and rationality of this technique, and has important realistic meaning in further understanding and improving this technique.
