The purpose of present study was to investigate the effect of dodgeball training on the throwing performance in elementary-school children. Total 125 boys and 159 girls ranged 2nd grade to 5th grade in elementary-school participated in this study. The subjects were classified into control group, dodge ball game training group (DBTR), throwing motion training group(TMTR), respectively. DBTR played 10 min dodge ball game in each training session. TMTR trained 15 times dodge ball throwing without game in each training session. Both DBTR and TMTR trained 3 times per week, continued 3 weeks in the school. Kinematic analysis was performed by two directional video camera recordings(30 frames second). Movement evaluation score during throwing movement was also used to categorize the throwing motion from immature pattern(score 1)to mature pattern(score 6). Throwing movement score was improved both 2nd and 3rd grade girls after the training in the DBTR and TMTR(p<.05). Moreover, throwing distance was increased in the 3rd grade girls(p<.01). Both shoulder and hip rotational velocities were increased in the 2nd grade girls of DBTR and TMTR(p<.01). Shoulder rotational velocity was increased in the 2nd grade boys of DBTR and TMTR(p<.01). The angle of ball release was increased in the 2nd grade boys of DBTR and TMTR(p<.01). It has been suggested that the dodge ball training has influenced throwing performance in the 2nd grade children and the 3rd grade girls.
