Abstract
Using an electro-pedometer which is commercially available, energy expenditure during walking andfor jogging was assessed, and was compared with that obtained by oxygen uptake (VO2). Thirteen male students and 12 female students exercised on 6 minutes duration tread-mill tests which velocities were 40, 60, 80, 100, and 120m/min for walking and 100, 120, 140, 160, and 180m/min for jogging, respectively. During e\ercise, energy expenditure was calculated by VO2 Value and respiratory exchange ratio, and was estimated by an electro-pedometer. There was a significant linear relationship between energy expenditures estimated by the pedometer and calculated by VO2 during walking and jogging. To predict energy expenditure more precisely by the electro-pedometer, it is svggested that more precise value of stride should be inputted into the pedometer. In conclusion, the present study showed that commer-cially available electro-pedometer is able to us.e for the estimation of energy expenditure with precise validity during walking and/or jogging.
