Mechanical Energy Consumption for Human Running

띔 거동에 대(對)한 기계역학적 일량의 계산

Mechanical energy consumption during human running was studied. The subject was modeled by an eleven segment planar open linkage system and analyzed by Newtonian equations of motion from film data with a sampling rate of 50 Hz. The motion data from films were smoothed by lower 7 harmonics before analysis. And this study was tried for a normal male subject running on a concrete floor. The mechanical energy consumption was evaluated from the five different criteria suggested by others and a joint energy consumption criterion newly devised based on the muscle contraction.
