Abstract
I measure the metabolism efficiency of the volitional and electrical stimulation cycling by FES and report it. A purpose of this study is that metabolism efficiency of the cycling by FES considers a low factor. It was 2 patterns of 20Hz and 50Hz, and the stimulation condition of FES calculated metabolism efficiency from the work that joint went at the time of a cycling for normal men and an oxygen uptake and a carbon dioxide output. The result was the efficiency that the cycling by FES was lower than the metabolism efficiency of the voluntary movement. It will be necessary to do a timing to stimulate a line to improve efficiency appropriately and strength of the stimulation is changed to make up for the mechanical work that decreased by muscle having got tired in future.
