The purpose of the present study was to evaluate the relationship between several physical fitness parameters and eyesight divided into 3 grades in @entity227 @entity1 and young male adults, and to investigate the effect of mild exercise training on physical and @entity1109 as well as @entity410 . Four subjects were @entity1939 ( @entity1939 ), 6 were semi-blind (SB) and 27 had amblyopia (AM). Physical fitness tests consisted of maximal @entity26 uptake (Vo2max), maximal pedalling speed and power, maximal stepping rate, and isometric knee extension strength. Compared with AM and SB groups, the @entity1939 group was inferior in all physical fitness parameters. Especially, Vo2max, in @entity1939 (26 ml.kg-1. @entity1009 ) was about 56% of that in age-matched Japanese sighted subjects and was significantly low compared with the AM and SB groups. Both muscle strength and maximal pedalling power corresponded to about 50% that of the age-matched sighted group. Six SB and 4 @entity1939 students (mean = 17.7 years) were trained for 6 weeks on a bicycle ergometer at an intensity of 50% VO2max. Training was undertaken for 3 days per week and maintained for 60 min per session. After training, physical and @entity1109 determined by the Cornell Medical Index improved significantly. These results indicate that low physical work capacity in @entity227 @entity1 and young male adults is due to the lack of physical activity, and that mild endurance training is effective in improving physical and @entity1109 as well as @entity410 .
