乒乓球单项技术稳定性评价标准的实验研究

利用特定比赛、多球计分、三维图像解析等方法对不同运动等级、性别的20名乒乓球运动员正手攻球的比赛成绩、成功率与准确度进行实验测量。主要采用双因素方差分析与秩相关分析方法分析了乒乓球单项技术稳定性评价标准的有效性,并利用参数变异系数与全距的比较分析了其评价标准的区分性。结果发现,乒乓球单项技术稳定评价标准无性别差异,对运动等级具有选择适应性,初学者适应成功率,而准确度更有利于评价高水平运动员。

The Experimental Research on the Evaluation Criteria of the Stability for Individual Technique of the Table Tennis

Through methods of particular game counting,more balls scoring and three-dimensional image analysis,the research was accomplished to measure and analyze such factors the 20 Table Tennis players with forehand techniques as their race results,their success rate and the accuracy rate of.The validity of the evaluation criteria on technique stability was made possible through two-factor analysis of variance and rank correlation,and the distinction with coefficient variation and the full range distinction.The results show that the evaluation criteria of the technique stability indicate no gender bias.Meanwhile the sports level is adaptive to the evaluation criteria with the success rate being more appropriate to beginners while the accuracy being more appropriate to high-level athletes.
