网球正、反手切削球“拍臂角”讨论及其教学辅助控制装置设计研究

A Study on Tennis Forehand and Backhand Chop "Racket Pole-Fore Arm Angle" and Design of Periphery Control Device for Teaching

采用图像(片)资料分析对比、文献资料研究、实验验证、数理统计等方法,对网球正、反手切削球技术进行分析。结果发现,网球运动切削球技术对“球拍控制”具有非常显著的特征。依据“运动学习过程”理论,探索性的提出“拍臂角”概念,并进一步探讨切削球“拍臂角”变化规律,构思设计了简便实用的“拍臂角”教学辅助控制装置。

With picture data analysis and contrast, literature study, experiment proof, mathematic statistics and other methods, this paper conducted an analysis to tennis forehand and backhand chop skills. The result shows that there are distinctive features regarding ＂racket control ＂-this crucial technique, Based on the theory of ＂Sports Learning Process＂ , this paper explores the notion of ＂racket pole forearm angle＂, and further studies changing laws of chop ＂racket pole-forearm angle＂,designs a single and practical teaching periphery control device.
