碩士 === 聖約翰科技大學 === 工業工程與管理系碩士在職專班 === 100 === This article is aimed to explore the difference of batting accuracy with spheroids of different diameters of table tennis in college students of different technological abilities. The method is taking 63 college students as experimenters. Three basic abilities are tested and distinguished into three groups-high ability group, medium ability group, and low ability group. Three kinds of different spheroids (38mm, 40mm and 44mm spheroids) are involved separately. Stand table backhand push and block and forehand batting accuracy are tested to understand the influence of accuracy by using three different diameter spheroids to bat . Statistical method adopts the variation analysis of the independent sample factor and the variation analysis of weight number factor. The showing level is set as α=. 05. The result is that according to using of stand table backhand push and block, in the low ability group, the accuracy of 44mm is obviously higher than the accuracy of 40mm and 38mm spheroids, reaching the difference of showing (p<.05);in the medium ability group, the acurracy of 44mm is obviously higher than the accuracy of 40mm and 38mm spheroids , reaching the difference of showing (p<.05); in the high ability group, the accuracy of 44mm is higher than the accuracy of 40mm and 38mm spheroid apparently, reaching the difference of showing (p<.05).and when the high ability group 44mm is higher than 40mm and 38mm spheroid apparently, reaching the difference of showing (p<.05).As for the low ability group in forehand batting, different spheroids have not reached the difference of showing (p<.05); medium ability group 40mm is superior to 38mm and 40mm spheroids, reaching the difference of showing (p<.05); high ability group does not reach the difference of showing on different spheroids(p<.05).The conclusion is that spheroids of different diameters can improve the batting accuracy of backhand push and block in college students of different technological ability.However, only in forehand batting, there is no apparent difference in the accuracy of the three groups.It reveals that among the high, medium, and low ability groups, 40mm spheroid and ball accuracy are superior to 38mm and 44mm spheroids.
