In my previous study (Oishi, 2010), I have reported the changes of body growth and physical fitness levels of the junior high school students in the Kumamoto University. In this paper, I analyzed the body growth and the effects of daily sports activity on the physical fitness levels of the upper grade students of elementary school in the Kumamoto city.A total of 5092 students were divided into daily sports or non-sport group, and their sports test data for 1) hand grip strength, 2) side stepping, 3) shuttle running, and 4) 50m running were analyzed and compared. The body height and weight were gradually increased in both male and female students during 4th to 6th grades, ranged 9-10% and 26-29%, respectively, with the significant increment by 10-50% of four sports test data in both students. These data suggested that the increase in body height and weight contributed to the enhancement of physical fitness levels.The physical fitness levels were gradually increased by 21-35% in both the daily sports and non-sport groups, but the levels were significantly higher in the daily sports group than the non-sport. Collectively these data suggested that the physical fitness levels for the upper grade students of the elementary school were gradually increased even in the non-sport students, but the daily sports activity enhanced the levels more in the daily sports group than non-sport students.
