The purpose of this study was to assess the physical activity and energy balance of weekdays and weekend in male high school students. Fifty healthy male high school students participated in this study. Anthropometric data were collected. Physical activity level (PAL) and energy intake for weekdays and weekend were calculated from a physical activity diary and food diary using the 24-hour recall method and interview. The resting metabolic rate (RMR) and estimated energy requirement (EER) were calculated from the prediction equations suggested in 2015 KDRIs. Total energy expenditure (TEE) was calculated by multiplying RMR by PAL. Mean age of subjects was $15.9{ pm}0.33years$ . The daily pedometer counts were significantly higher in the weekdays (12,837 steps) than in weekend (6,661 steps) (P $1.63{ pm}0.17$ ) was significantly higher than that ( $1.37{ pm}0.26$ ) of the weekend (P $2,847.2{ pm}681.5kcal$ ) and TEE ( $3,046.3{ pm}437.3kcal$ ) of weekdays were significantly higher than those of the weekend. The results of this study would be useful to develop nutrition and exercise programs for male high school students on weekdays and weekend, respectively. |
