We examined bone mass measurements and the results of a questionnaire survey in fifth- and sixth-grade elementary school students (n=176) in Tokyo, and analyzed the association with the physical fitness. There were positive correlations between the bone mass and grip strength, standing long jump, or score of the grip strength and standing long jump. In addition, belonging to a sports club and the kind of physical activity on school days or holidays were associated with the score of the grip strength and standing long jump. Furthermore, the amount of calcium intake and frequency of milk or yoghurt intake were also associated with the physical fitness. It is necessary to examine other physical fitness measurements and the frequency of other food intakes, and we hope to generate useful data for the prevention of locomotive syndrome in the future.
