This study investigated the impact of daily activity and athletic ability, especially for the amount of exercise on radius bone density in high school boys. The findings are as follows. 1. The more active students who have high physical fitness tend to have greater radius bone density. There was a significant positive correlation between radius bone density and the number of steps a day (p<0.01). In addition, there were significant correlations between radius bone density and the grip strength, sit ups, side step, 50m run, standing long jump, handball throw and total score. 2. The students who had the experience of exercise in elementary school and/or junior high school and who belonged to the club activity showed the significantly higher radius bone density, mean number of steps and the values for all kinds of physical fitness test. 3. Regarding about early developmental history, the students who had the heavier body weight and who consumed milk and daily foods in lager quantities in infancy and childhood tended to be the higher radius bone density. In summary, the vigorous exercise was desirable to enhance the radius bone density in boys. In addition, the physical education during childhood should be reviewed from both quantitative and qualitative aspects to maintain and progress the bone density.
