本研究目的在於比較開放式、閉鎖式、非運動員等不同運動技術特性選手動態視力之 差異。某體育學院 12 名排球和 12 名柔道選手為開放式運動特性之受試者，某體育學院 12 名射箭和 12 名游泳選手為閉鎖式運動特性之受試者，某體育學院 12 名運休系非專長生及 某大學 12 名同學為非運動員之受試者；所有受試者均於室內安靜空間，分別完成向右 (DVA-R)、向左(DVA-L)、向下(DVA-D)、向上(DVA-U)等動態視力測試，再以 Kruskal-Wallis 單因子等級變異數進行統計分析。結果發現向上(DVA-U)動態視力為開放式運動技術特性選 手顯著優於閉鎖式運動技術特性選手和非運動員(p<.05)，其他所有動態視力均顯示開放式 和閉鎖式運動技術特性選手顯著優於非運動員(p<.05)。本研究認為不同運動技術特性選手 動態視力差異性不大，不論運動技術是否隨個體外部情境變化而作相應變化的開放式和閉 鎖式的選手均具有較佳的動態視力。

The purpose of this study was to compare Dynamic Visual Acuity among open-skilled athletes, close-skilled athletes and non-athletes. twelve volleyball and twelve judo athletes from Taipei Physical Education College defined as open-skilled group. twelve archery and twelve swimming athletes from Taipei Physical Education College defined as close-skilled group. twelve students from department of leisure management and twelve normal college students defined as non-athlete group. All subjects measured DVA-Right, DVA-Left, DVA-Down, and DVA-Up by using ATHLEVISION software, respectively. Kruskal-Wallis independent sample test was used to compare all data. The results showed that open-skilled group had significantly better DVA-Up ability than close-skilled and non-athletes groups (p<.05). Open-skilled and close-skilled groups both have significantly better DVA ability than non-athlete group (p<.05). The finding suggested that DVA ability was not significant difference between open-skilled and close-skilled athletes. According to environmental change, both open-skilled and close-skilled need to do appropriate reaction, as well as they should be have good DVA ability.
