The purpose of this study was to investigate that the effect of total energy expenditure and factors associated with fatigue (blood pressure, heart rate, glucose and lactate concentration) following different sequence of exercises undertaking by either resistance weight exercise or aerobic running. Total 10 (but 2 persons were dropped out during experimental period due to their unpleasant body condition) healthy University students were voluntarily participated all experimental procedures. All subjects were tested for maximal oxygen uptake (VO2max, 49.8±5.4 mL∙kg∙min-1) and estimated for their one repetition maximum (1-RM) from 6 different weight loaded exercises (i.e., bench press, incline press, lat pull down, bent of row, leg curl, and leg extension). Based on their maximal aerobic and resistance capability, 65% of VO2max and 1-RM values were calculated, and used as an aerobic running exercise and a resistance weight exercise intensity. One hour exercise (30 min for aerobic running exercise and 30 min for resistance weight exercise, but exercise order was altered) was undertaken twice by any individual subjects, and total energy intake, heart rate, blood pressure, and blood glucose and lactate concentrations were measured. When exercise order was changed, total energy expenditure did not significantly altered (526.3±42.3 kcal, Aerobic-Resistance vs. 497.7±50.5 kcal, Resistance-Aerobic; p>.05). Regardless of order of exercise, energy expenditure was significantly higher during aerobic running exercise compared to resistance weight exercise. Similar to the energy expenditure, average heart rate was not also significantly different when exercise performed by different orders (p>.05). Heart rate was, however clearly higher during aerobic running exercise than resistance weight exercise (p.05), and also there was no different blood glucose level during two different exercise programs (p>.05). The patterns of blood lactate change were almost identical between two exercise sessions, but it was dramatically higher during resistance weight exercise than aerobic exercise. Lactate concentration was also maintained with higher values throughout the recovery periods with exercise session followed order with aerobic-resistance compared to the order with resistance-aerobic. In conclusion, exercise order would not be major factor to influence of body composition and to increase of energy expenditure. Key words: Combined exercise, Aerobic running exercise, Resistance-weight exercise, Energy expenditure.
