Outline of Final Research Achievements

In this study, as a new method for immediate improvement of sport performance, a pre-loaded exercise (pre-loaded exercise) was developed using sprinting as an example to activate or inactivate muscle activity in a specific muscle group to change a previously learned form (pre-loaded exercise method), using the mechanism of post-activation potentiation as an aid. The purpose of this study was to clarify the method of improving the form by activating or inactivating the muscle activity of a specific muscle group to change an existing form (preload exercise method). As a result, we found that when preload exercise is used as an immediate improvement method for new sport performance, it is necessary to incorporate not only "intense preload exercise," which focuses on the muscle groups involved and applies a large load, but also "light preload exercise (auxiliary exercise)," which ensures the basic overall movement structure of the sport to be performed.

Academic Significance and Societal Importance of the Research Achievements

本研究の成果における学術的な意義は、運動学習における「運動の転移」に関する研究や知見に貢献するものと考える。具体的には、強度の事前負荷運動を行うことと基本的な運動構造を担保した軽度な事前負荷運動（補助運動）を適切に組み合わせがないと、目指す運動技能を成就するための新たな運動意識やフォームを学習者へ無意識的に誘導できないということを示したことである。このことは、体育科教育やコーチングの研究で、目指す運動技能改善に求められる運動教材や練習運動をどのように選択し、配置すべきかを考える研究において重要な手がかりを提示したものと考える。
