摘要
简要分析了传统的排球发球技术水平评价方法存在的不足,给出了排球发球质量等级划分办法,在此基础上,提出了排球发球技术水平的全概率评价方法.分别用2种方法对中国女排队员在北京奥运会上的发球技术水平进行了评价,并对2种评价结果进行了比较和分析,得出了全概率评价方法优于传统评价方法的结论.定义了发球威力的概念,计算了中国女排队员的发球威力值,并进行了2种评价方法评价结果与威力值的斯皮尔曼等级相关分析,得出全概率评价方法的评价结果与威力值具有较高一致性等结论.
Deficiencies of traditional evaluation method in regard to technical difficulties of volleyball serve were analyzed. The division method for quality grade was evaluated, then total probability evaluation method was put forward. The two methods were used in parallel to evaluate Chinese women＇s volleyball team. From such data it was concluded that the total probability method is superior to the traditional one. The conception of serving power was defined, and used to calculate this value for players on the Chinese women＇s volleyball team. By Spearman correlation analysis, it was found that that total probability evaluation method could accurately reflect serving power.
