Sports and Kinetic Visual Acuity

Kinetic vision acuity (KVA) is an index developed in Japan that refers to the capacity recognize a moving object moves back and forth against observer. This review outlines history of KVA studies on conducted at Faculty Health Sports Science Juntendo University, i.e. characteristics athletes, factors associated with KVA, sports age-dependent decline effects docosahexaenoic acid (DHA) astaxanthin KVA. was defined early 1960s, measurement device invented 1968. Studies began 1990s. In track-and-field athletics skeleton, winter downhill event, higher-ranked athletes had higher than lower-ranked athletes. Although cannot be predicted from static visual or reaction time, significant correlation found between peak latency visual-evoked potentials. could not improved by training did change age 8 17 years. contrast, habitual practice kendo may inhibit DHA also improve subjects low KVA; however,
