Outline of Final Research Achievements

The energy cost associated with the vertical movement of the body during incline running could be estimated using the energy cost of repeated vertical jumping. The energy expenditure was greater in sledge jumping, which can change the moving direction of repeated jumping, on a steeper incline than that on a lower incline. The results indicated that the energy expenditure would be smaller in horizontal tasks than in vertical tasks. Additionally, the mechanical work of the knee and ankle joints would associate with energy cost.

Academic Significance and Societal Importance of the Research Achievements

ランニングエコノミーに関する研究は国際的に数多く行われているが,ランニングそのものを研究して得られる知見には限界がある.本研究ではランニングを模したよりシンプルな運動(Mimicking exercise)である連続ジャンプを用いて検討を行った.ランニングでは,水平方向の運動を鉛直方向の運動から完全に切り離して実施することはできないが,Mimicking exerciseを用いることで両者に相互に影響している要因を整理して検討することができた.
