本研究是以參加民國入十七年及入十入年兩屆、莒光盃'中等學校排球賽的高男組及高女組之比賽隊伍為研究對象，探討排球新、舊規則對於比賽時間的差異性，依資料分析後，得到下列結果:一、在新、舊規則的得分方式對縮短比賽時間的差異性方面:(一)每局所花費的比賽時間，在高男組方面有顯著性差異，而在高女組方面則並無顯著性差異。(二)榮得前四名隊伍，在決賽中所花費的時間，在高男組方面，有顯著性差異，而高女組則無顯著性差異。(三)在預賽和決賽所花費的時間，採舊規則時，高男組有差異性，而高女組則無差異性，若採用新規則，則兩組皆未主現出差異性。二、在斬、舊規則的比賽時間和得分方式之關偉、上顯示，採新規則每得一分的比賽時間，約為採舊規則的二分之一強時間。

This research studies on whether the new rules will cause time shortening and how the new rules differ from the old ones. We use one-factor analysis of variance in statistical Techniques to examine the difference in time controling between the original and new rules. Also， we try to find a time-score equation to examine the differences between the old and new rules in time-score relation. The results are as follows : 1. Thescore system to time shortening effects (1)There is obvious difference in the time spent each set in Senior Male teams， but not in Senior Female teams. (2) Thereis obvious difference in the time spent in the finals in the first four Senior Male teams， but not in the first four Senior Female teams. (3) By using the old rules， the time spent in both quater-finals and finals has obvious differences in Senior Male teams， but not in Senior Female teams. Yet， by using the new rules， no difference ever shows in both Male and Female teams. 2. Thetime-score equation shows that the fime to win a point has reduced to half when use the new rules.
