摘 要:运用录像观察和三段分析法对实行新规则后的14名世界优秀男选手的比赛情况进行了统计分析,并将所得数据与各评估指标进行对比,结果发现:1)新规则执行后世界优秀男乒选手在三段使用率上发生了新的分配形式,三段的使用率有明显的“向平均数回归”的趋势。该结果提示新规则实施后,世界优秀选手在前三板的争夺更加激烈。2)与国外运动员相比,中国选手在接抢段的使用率更高,表明中国运动员更好地适应了新规则。此外,多名世界顶尖球手在相持段得分率的评估中不及格,作者据此认为新规则实施后,三段分析法的评估标准有必要进行修订,以跟上形式发展的需要。Adopted the three-phase method and video-observation method, this study conducted a profound and extensive analysis in a .sample of 14 elite male table tennis players. Through cow,paring the data with the previous evaluation stan- dard, it was found that ( 1 ) after the implementation of new rules, the distribution of using rate of three phases among elite male players has changed to a significant tendency of “regression to average”. It indicated that for elite players the contest in first three balls is more serious than before; and (2) Chinese players' using rate of reception was significant higher than other players. From this perspective, it was likely that Chinese players adapted to the new rules better than other players. Besides, it is recommended that, after new rules adopted, the evaluation standard of three-phase method should be amended.
