Outline of Final Research Achievements

This study aimed to clarify the characteristics of high intensity training in swimming by investigating the effect of different swimming intensity on the swimming technique. As results, propelling efficiency did not change between maximal effort front crawl swim and low intensity swimming. However, when the stroke frequency was increased above that of maximal effort swim, it was clarified that co-activation level of the agonist and antagonist muscle at the upper limb increased. Furthermore, the underwater stroke movement change during the latter stroke phase, and resulted in an un-efficient stroke technique. From the present research, even the beneficial effect of high intensity training is reported on physiological aspect, the importance to adjust the stroke frequency to an optimal level was indicated when prescribing a high intensity training program in competitive swimming event.

Academic Significance and Societal Importance of the Research Achievements

スポーツ現場において有酸素性能力と無酸素性能力の双方を向上することのできる高強度トレーニングが注目されているが、高い強度で泳ぐことが泳技術に与える影響については明らかとなっていない．本研究結果より，低強度泳と高強度泳時における3次元動作，手部推進力および筋活動量の変化を学術的に究明した．そのことにより，競泳競技のトレーニング現場において高強度トレーニングを処方する際に，水泳運動で重要となる泳技術への影響を踏まえたトレーニングプログラムの立案法について提案することが可能となった．
