Individuals with simmilar static visual acuity(SVA) have widely different dynamic visual acuity(DVA). While SVA is primarily related. to the resolving power of eye, DVA is related more to the efficiency of the entire oculomotor system. At low target velocites, there is high correlation between SVA and DVA, while the correlation decreases as target velocity is increased. This study was the DVA compared using samples of nonathlete college students(male 14, female 12) and athletes(9 fensing players in middle school). Subject reported diretion of Landolt Cs target(2.1cm in projected size) exhibting uniform angular motion produced by rotating mirror projection system. The results showed a statistically significant difference between the nonathlete and athletes groups. The mean DVA is 78.46±15.67degjsec for the nonathletes group and 93.33±14.14deg/sec for athletes group. Also, SVA is not related DVA in athletes. It was considered that these results will provide a foundamental data for the future study of the sports and visual performance.
