| Outline of Final Research Achievements |
On land, impact force can be utilized as the storage and release of elastic energy during terrestrial gait. This elastic behavior of muscle-tendon interaction has been examined during human dynamic movements. In swimming, however, impact forces are low and it remains questionable how swimmers can enhance the swimming efficiency and whether elastic strain energy can be utilized during swimming. Therefore, the purpose of the present study was to examine the muscle-tendon behavior together with muscle activities during the human underwater dolphin-kick of swimming. In results, the fascicles and tendinous tissues performed a stretching-shortening action during the dolphin-kick swimming. With increasing swimming speeds, the tendinous tisseus were stretched more and also the recoil of the tendinous tissues was increased. Therefore, the tendinous elasticity can play important roles not only on land but also under water.
