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.

本研究の目的は,立ち五段跳の動作特徴を明らかにし,指導場面への知見を得ることであった。通常の立ち五段跳と上肢を固定した条件下での立ち五段跳を実施させた。立ち五段跳の跳躍距離を規定する要因として,鉛直速度,接地時間,腰回旋角度,振込み速度が挙げられた。また熟練者は,より離地直前で肩と腰の回旋の切り返しを行っていた。接地期の肩と腰の回旋動作範囲は,熟練者が最も小さく,未熟練者ほど大きくなる傾向を示した。上肢を固定した試技は,跳躍距離,身体重心速度,脚スイング速度,振込み速度を低下させ,接地時間,体幹の前屈角度を増加させた。指導場面への知見として,短い接地時間で実施できる運動様式であることを優先させながら,遊脚の振込み動作を強調すること,接地期の腕の振りはコンパクトに実施することが挙げられた。
