Abstract

The purpose of this study is to estimate the influence of impact timing of baseball hitter on the five different color of the ball. The five different color of the ball are the White, Black, Red, Blue, and Yellow color. The subjects who was selected for this study were all sixty, each grade twenty in high school students, respectably. The results are as follows: 1. Comparison of , 2nd, 3rd grade in high school. 1) The influence of impact timing of baseball hitter according to five different color for 1st grade in high school student showed the level of significance of p<.036, and the result of post-hoc(Tukey HSD) showed more higher score on the Yellow color than the Black. 2) The influence of impact timing of baseball hitter according to five different color for 2nd grade in high school student showed the level of significance of p<.030, and the result of post-hoc(Tukey HSD) showed more higher score on the Yellow color than the Black. 3) The influence of impact timing of baseball hitter according to five different color for 3rd grade in high school student showed the level of significance of p<.034, and the result of post-hoc(Tukey HSD) showed more higher score on the Yellow color than the Black. 2. The Results of Expectation Timing of All Subjects The influence of impact timing of baseball hitter according to five different color for all high school student showed very significant level of p<.000, and the result of post-hoc(Tukey HSD) showed more higher score on the Yellow color than the White, more higher score on the Blue color than Black, and more higher score on the Yellow color than the Red.
