The purpose of this study was to investigate the long-term effect of practice of overarm throw (using tennis ball) for elementary school children by measuring throwing distance. Twelve boys and 15 girls in the 1st grade and 14 boys and 12 girls in the 4th grade had practiced overarm throw for 8 weeks according to predetermined instruction. The effect of practice on throwing distance was tested by using T-test. The contribution of the practice on the mean throwing distance, 10 months after the practice, was not significant although significant just after the practice.
