The purpose of the present study was to investigate the validity of a calorie counter (Kenz Calorie Counter Select 2) for estimation of daily energy expenditure. The daily energy expenditure values by the calorie counter were compared with the values of the time-study and the 24 h heart rate methods using seven young women who work out on a regular basis. The main findings of this study are as follows ; 1) The mean (± SD) value of daily energy expenditure obtained by the calorie counter, time-study, and 24 h heart rate method was 2,162 ± 236 kcal, 2,346 ± 269 kcal, 2,225 ± 449 kcal, respectively. These values were not significantly different, althouth the value of the calorie counter methods appeared to be a little lower than other two methods. 2) The daily activities were placed into five categories based on the intensity; sleeping, resting (lying, sitting or standing), light activity, medium activity, above medium activity. The energy expenditure value of each category was compared among the three methods. The calorie counter methods estimated the energy expenditure higher for sleeping, and lower for medium and above medium activity compared to other two methods. These results suggest that the calorie counter method is useful for the estimation of daily energy expenditure for active young women as both the time-study and 24 h heart rate methods, and the validity are comparatively high.
