According to individual defense places, we divided the players into infielders and outfielders to compare the differences of swiping speed of players at different defense places. We took 17 players in Taipei City Baseball Team, 16 senior-baseball-league players in Yang-Ming Senior High Baseball Team, and 13 junior-baseball-league players in Chongqing Junior High School for subjects. We used swiping speed test system to get the parameters of swiping speed of players from each rank which will be statistically analyzed through SPSS 14.0 for Windows. This research mainly compared the differences of swiping speed between adult baseball league, senior baseball league and junior baseball league with one-way analysis of variance of independent sample. And then, independent samples, t-test, were used to compare the infielders’ and outfielders’ differences of swiping speed. The standard of significant difference was α<.05. Please see the result of the study below: First, Among baseball players of different levels, in the result of swiping speed, the swiping speed of players in adult league was 90.7±10.4 km/hr; senior league was 83.4±8.8 km/hr ; junior league was 78.4±8.8 km/hr. After comparing the three different groups, the obvious difference (p<.05) indicated that the swiping speed of players in adult league was apparently faster than that in junior league (p<.05). Second, the swiping speeds of infielders and outfielders in adult league were respectively 90.8±11.7 km/hr and 90.6±6.2 km/hr. The result wasn’t notable(p>.05). Third, the swiping speeds of infielders and outfielders in senior league were respectively 81.9±7.2 km/hr and 86.6±11.8 km/hr. The result wasn’t notable(p>.05). Fourth, the swiping speeds of infielders and outfielders in junior league were respectively 80.7±6.3 km/hr and 76.5±7.6 km/hr. The result wasn’t notable(p>.05).

碩士 === 輔仁大學 === 體育學系碩士班 === 101 === Abstract
This study mainly discussed the differences of the swiping speed between the players in junior baseball league, senior baseball league and adult baseball league. According to individual defense places, we divided the players into infielders and outfielders to compare the differences of swiping speed of players at different defense places. We took 17 players in Taipei City Baseball Team, 16 senior-baseball-league players in Yang-Ming Senior High Baseball Team, and 13 junior-baseball-league players in Chongqing Junior High School for subjects. We used swiping speed test system to get the parameters of swiping speed of players from each rank which will be statistically analyzed through SPSS 14.0 for Windows. This research mainly compared the differences of swiping speed between adult baseball league, senior baseball league and junior baseball league with one-way analysis of variance of independent sample. And then, independent samples, t-test, were used to compare the infielders’ and outfielders’ differences of swiping speed. The standard of significant difference was α<.05. Please see the result of the study below:
First, Among baseball players of different levels, in the result of swiping speed, the swiping speed of players in adult league was 90.7±10.4 km/hr; senior league was 83.4±8.8 km/hr ; junior league was 78.4±8.8 km/hr. After comparing the three different groups, the obvious difference (p<.05) indicated that the swiping speed of players in adult league was apparently faster than that in junior league (p<.05).
Second, the swiping speeds of infielders and outfielders in adult league were respectively 90.8±11.7 km/hr and 90.6±6.2 km/hr. The result wasn’t notable(p>.05).
Third, the swiping speeds of infielders and outfielders in senior league were respectively 81.9±7.2 km/hr and 86.6±11.8 km/hr. The result wasn’t notable(p>.05).
Fourth, the swiping speeds of infielders and outfielders in junior league were respectively 80.7±6.3 km/hr and 76.5±7.6 km/hr. The result wasn’t notable(p>.05).
