Correlation Between Mechanical and Metabolic Energy During the Gait Cycle With and Without Jumping Stilts

The aim of this work is to evaluate the correlation between the mechanical and metabolic energy, during the gait cycle of a subject equipped with and without energy storage devices called "Jump Stilts". In order to calculate the mechanical energy, as first step, a video of the moevement was recorded. Then, the video was post-processed to obtain the sagittal trajectories of eleven geometric points located opportunely on the subject. Finally, a multi-bodies model of the subject motion was implemented providing the mechanical energy during the gait. On the other hand, the metabolic energy was acquired via a portable metabolic meter during the gait of the subject.
