不同棒球球齡選手之動體視力發展特徵

Characteristic of developing dynamic visual acuity by different baseball training period

目的：本研究目的在於探討動體視力隨棒球球齡之發展情形。方法：以參與棒球訓練0.2至16年的139名選手為研究對象，利用運動視覺測試軟體ATHLEVISION進行動體視力測試，所有受試者分別測試視覺疲勞、靜止視力以及動體視力。結果：發現棒球球齡在6年以內的棒球選手，其動體視力會隨棒球球齡的增長而增進；在6至14年的棒球球齡之間，動體視力則呈現逐年下降的趨勢；在14至16年棒球球齡之間，動體視力呈現些微增進的趨勢。結論：本研究結果與動體視力隨年齡變化的曲線相似，但接受棒球訓練的選手其動體視力的變化較為明顯，特別是在10歲至18歲階段。

Purpose: The purpose of this study was to investigate effect of baseball training period on dynamic visual acuity (DVA). Methods: 139 male baseball players with training period from 0.2 to 16 years participated voluntarily this study. ATHEVISION computer software was used to measure dynamic visual acuity. All subjects measured visual fatigue, static visual acuity, and dynamic visual acuity, respectively. Results: The result of this study was show that DVA increased within 6 years of training period and during 14 to 16 years of training period, but it decreased during 6 to 14 years of training period. Conclusion: This result was similar with DVA-age relationship curve. However, baseball player's DVA have more vary, particularly during 10-18 years old.
