ABSTRACT: To find out the basal metabolic rate (BMR) and the energy cost of some common physical activities, a cross-sectional descriptive study was conducted on 30 male medical cadets, aged 18.1Ã‚Â±0.46 years, selected randomly from 12th intake of Defence Services Medical Academy (DSMA), Yangon. BMR and the energy cost of seven common physical activities were measured by open circuit indirect calorimetry method. Mean BMR of the subjects was 0.937Ã‚Â±0.024 kcal/min. The energy cost of basic activities such as sitting, standing and walking were 1.08Ã‚Â±0.11 kcal/min, 1.25Ã‚Â±0.15 kcal/min and 2.95Ã‚Â±0.36 kcal/min, respectively. The energy cost of marching and running were 4.06Ã‚Â±0.43 kcal/min and 8.35Ã‚Â±1.21 kcal/min, respectively. The energy cost of social service duties such as sweeping and hoeing were 3.93Ã‚Â±0.52 kcal/min and 5.44Ã‚Â±0.94 kcal/min, respectively. Based on the metabolic equivalent times (METs), sitting and standing activities were classified as light intensity whereas walking, marching, sweeping and hoeing were moderate intensity. The running activity fell into hard/vigorous intensity. BMR and the energy cost of seven common physical activities were comparable to Asian values but lower than the Western and European values. The results of this study could be used as baseline data for measuring total daily energy expenditure of medical cadets from DSMA in providing the information about energy requirement.
