The purpose of this study was to investigate the change in physical fitness of elementary school children who participated in the long term sports classes using Ballschule program that has received high evaluation in Germany, and to compare the physical fitness and exercise habits of the children and that of those who had not participated in the classes. In addition, the aim of this study was to examine the effects of Ballschule program on the growth of child, and to obtain basic data to make a physical fitness program for elementary school children. First, a total of 47 children, the 2nd and 3rd grade, practiced in sports classes of Ballschule, participated in a sports class held over the long term. There was the improvement with physical fitness and balance in the total score of the physical fitness test. Next, In the comparison of a total 34 children of the 2nd, 10 children who had participated in sports classes of Ballschule and 24 of children who had not, it is confirmed that the total coordination score of Post-test was higher than that of Pre-test in the former children. As a result, it is suggested that the improvement of the physical fitness was caused by the long-term Ballschule program. We could consider Ballschule program as an effective training program, and furthermore we need to examine the validity of Ballschule program as school education. This study elucidated the importance that we should take unspecialized physical fitness program such as Ballschule for developing children. However, it is necessary that we demonstrate the effects of the Ballschule program by using other factors of physical fitness besides ability of coordination that have been central in test heads. And then, a program of Ballschule suitable for Japanese original social context must be suggested and practiced so that Ballschule will be familiarized, applied and practiced in various occasions.

This study aimed to investigate the acute effects of sprint training on sprint motions evaluated by the observational motion assessment method and sprint velocity in elementary- and middleschool students. 38 elementary- and middle- school students performed 50m sprint tests before and after the 30-min training intervention, consisting of the mini-hurdle sprinting and the rebound jump exercises. The sprint velocity from 20m to 40m was measured as the mean sprint velocity. The sprint motion was captured by video cameras, and it was qualified using the observational motion assessment method. No significant change was found in the mean sprint velocity between pre and post sprint tests(P=0.567, d=0.020). Meanwhile, the scores of the motions, such as the direction of arm swinging(P=0.001, d=0.405), the range of motion of the legs(P=0.031, d=0.191)and the timing of the scissors motion(P=0.029, d=0.304)were significantly improved in the post test. Therefore, our results suggested that acute sprint training did not improve the sprint velocity, but sprint motions.

本研究では,1996年度および1997年度日本選手権大会において,100m自由形に出場した一流選手を対象に競泳のレース分析による各パラメータから検討を行った。分析の結果,1996年度および1997年度ともに決勝進出者は予選失格者よりも,競技レベルにおいて有意に優れていることが明らかになり,年度間の比較では,男女ともに統計的な差異は認められなかった。また,100m自由形レースにおいて,ターン局面は競技力向上に有効な要因となることが示唆された。スタート1回制については,1996年度と比較して1997年度のスタート局面速度の低下がみられ,特に決勝進出者は顕著に影響していることが散見された。ストロークの特徴を表すパラメータであるストローク長およびストローク頻度は,高い負の相関関係があり,それらは従来の方法よりも細部に分類する必要性が示唆された。The purpose of this investigation was to analyze of races and stroke characteristics for the Japanese elite swimmers who had participated in 100-m freestyle event at the 1996 and 1997 All Japan swimming championship. The performance of 32 male and 32 female swimmers in the event were analyzed to determine 14 parameters and to compare within each year and between 1996 and 1997, to asses the relationships between these parameters. The results as follows; 1) The female and male finalist swimmers were superior more than preriminary swimmers in swimming performance. 2) A statistical significant difference was not admited both female and male swimmers in the comparison of swimming performance at the 1996 term and 1997 term. 3) It was suggested that maintaining the 25-45m and 75-95m of stroke phase velocity become the factor of swimming performance improvement. 4) It was able to be comfirmed that the turn phase was also important in the race of 100-m Freestyle. 5) Stroke length and stroke rate showed a high negative correlation in this study was suggested from the current method of race analysis. 6) The once start system had the influence, especially, the finalist was remarkable.

本研究では,水中水平姿勢時での,換気量の変化に応じた手部・足部の鉛直方向の力を計測し,浮力と浮心重心間距離の即時測定システムを構築することを目的とした.加えて、浮心重心間距離と水泳のパフォーマンスとの関係について調査することも目的とした。結果は、換気量の変化に対応した手部と足部にかかる力を測定でき,換気量とも直線の関係にあった.よって本システムにより,簡便に水中水平姿勢での浮力と浮心重心間距離を求められた.加えて、水泳選手は、非水泳選手に比べて浮心重心間距離の短い傾向にあることが判明した。以上のことから、本システムは、水泳パフォーマンスの有益な評価法として利用できるものと考えられる。

The purpose of this study was to investigate the changes in physical fitness and exercise habits of elementary school children over two years, and to compare the physical fitness and exercise habits of children who had not participated in the sports class with those of children who had. In addition, this study aimed to obtain basic data to make a physical fitness program to be held over the long term. A total of 622 children, from the 1st to the 6th grade, participated in the physical fitness test. 102 children had participated in a sports class held twelve times and for approximately 18 hours in total over twelve weeks. The physical fitness of the children in this study was lower than the average for Japanese children. However, the improvement rate of the scores in the physical fitness test over two years was higher than that of the average for Japanese children. In the comparison of the children who had not participated in the sports class with the children who had, there was no significant difference in the results of the physical fitness tests. When the results about the child's physical fitness were fed back to parents to investigate the parents' attitude, approximately 95% of parents answered, "I am interested in my child's physical fitness and exercise habits". However, there was a tendency for parents of children in the upper grades not to be interested in their child's physical fitness and exercise habits in comparison with parents of children in the lower grades, even though the physical fitness of the children in the upper grades in this study was remarkably lower than the average for Japanese children. Therefore, it is thought that it is necessary for the physical fitness test and the sports class to continue to be held over a long period of time so that daily exercise and sports may influence the improvement of physical fitness.

The purpose of this study was to determine the critical combination of all four elements which expressed the threshold of fatigue in interval training by using the critical swimming velocity that was an effective index when we set training strength, and to make a model that we could use as an indicator when we prescribed the training menu that accepted an individual. Only for 50m at repeated distance, we set a different rest time in three phases of different swimming velocity each and performed a test to let subjects repeat exercise up to fatigue. In addition, we measured the maximum repetitions that could repeat exercise. As a result, it became clear that the maximum repetitions that could repeat interval training without reaching fatigue in a certain swimming velocity was in proportion to the total rest time. And then, we were able to see the relations with the repetitions and the rest time in three phases of different swimming velocity. Furthermore, we were able to get relations with the rest time and the swimming velocity which expressed the threshold of fatigue in the arbitrary repetitions by fixing the repetitions. It was concluded that we were able to determine the critical combination from the above-mentioned by this study.

水泳競技(競泳)のレースには、ストローク局面、スタート局面、ターン局面及びフィニッシュ局面が存在し、競技力向上にはこれらの要素をより客観的に評価していく必要がある。そこで、我々は、1987年より、ビデオ映像を用いた競泳のレース分析に関する研究を開始し、レース中における各要素を客観的に評価して、それらのデータを選手や指導者にフィードバックすることを試行してきた。そこで、本研究の目的では、1)大幅なハードウェアの改良により、分析時間の短縮及び分析データの精度を高めること、2)システムアップとソフトウェアの開発により、自動データ入力を試みること、3)個人データベースのネットワーク化及び個人のデータの数年間の比較を瞬時に行えるようにすること、4)レース分析結果より、競技力向上に活用可能な研究成果を得ることを目的に行ったものである。その結果、レース分析の実験システムにおけるハードウェア及びソフトウェアの開発により、分析データの即時フィードバックを実現することができた。また、過去5年間のレース分析結果の個人別データベースを作成し、インターネット上で閲覧可能なデータベースシステムとしての構築に成功した。これらのデータは、個人名、種目、大会等のキーワード入力により、個人データの数年間の比較または選手間の比較を瞬時に行えるようにした。さらに、これまでのデータを活用することで、スタート、ターン及びフィニッシュタイムから、それらの技能の能力を評価することも可能となった。
