Baseball is one of the favorite sports in Taiwan and more people are paying close attention to the performance of the national baseball teams in the international tournaments. Therefore, the purpose of this study was to compare the Dynamic Visual Acuity among four- stage members of the national baseball teams. 68 members from the Chinese Taipei baseball team from four stages participated voluntarily in this study. All subjects' visual fatigue, static visual acuity, and dynamic visual acuity were measured. Kruskal-Wallis one-way analysis of variance by ranks and Dunn's multiple comparison procedure were used to analyze all the data. The results of this study indicated that adult players have better DVA-L, DVA-D, DVA-U, and DVA-ver than the senior high student players and junior high student players (p<.05). DVA-hor and DVA are also better in adult players (p<.05). This finding suggested that DVA should be a critical parameter in selecting adult members of the national baseball team.
