Visual acuity plays an important role in Kendo skills, however there are few studies of the systematic visual functions of Kendo players. We studied the visual acuity of male Kendo players in three groups (10 Kendo players designated by Japan Kendo Federation,11 college varsity players and 14 non-varsity players).The visual acuity was estimated by measuring static visual acuity (SVA), kinetic vinual acuity (KVA), dynamic visual acuity (DVA), contrast sensitivity, eye movement, depth perception, visual reaction time (VRT), and eye-hand coordination. There was no statistical difference in all-visual parameters between designated and college varsity players. The eye-hand coordination of designated and college varsity players were better than college non-varsity players. The depth perception of college varsity players was better than that college non-varsity players. On the contrary, visual reaction time of non-varsity players was superior to that of varsity players whereas there was no significant difference between desiganted and college non-varsity players. There was significant correlation between SVA and KVA (r=0.669, p< O.001), contrast sensitivity (0.584, p<0.001). These results indicate that the eye-hand coordination may play an important role in Kendo performance.
