The purpose of this study was to investigate excess post-oxygen consumption (EPOC) following three types of exercises used in resistance training. Eight healthy trained men (age=21.9±1.0 yr; height=173.4±5.8 cm; body weight=69.7±6.5 kg, body fat=23.2±1.6%) performed the following three types of resistance exercise on separate days.: 1) bench press (BP),2) dead lift (DL),3) squat (SQ),which consisted of 5 sets and 2 min interval between sets. All resistance exercises were performed to maximum repetitions with loads of 75% one-repetition maximum. Expired gas and heart rate were continuously monitored during the exercise sessions and for 120 min afterwards. The mean values for oxygen consumption and heart rate, total of energy expenditure during exercise in the DL and SQ exercises were found to be significantly greater than that in the BP exercise (P<0.05).The duration of EPOC in DL and SQ exercises were longer than that in the BP exercise, and total of EPOC in the DL and SQ exercises were found to be significantly greater than that in the BP exercise (P<0.05).However, there were no significant differences in total of EPOC between DL and SQ exercises. In the same exercise intensity, it was suggested that DL and SQ exercises increase oxygen consumption during exercise and EPOC more than the BP exercise. The results of this study suggest that resistance exercises to activate muscles of the lower extremity elicit greater energy metabolism in comparison to resistance exercises using the upper extremity.
