Abstract

To investigate effect of resistance training and aerobic training on post-exercise oxygen consumption(EPOC), oxygen comsumption(VO2), total energy consumption, catecholamine, cortisol, growth hormone and free fat acid, lactate, two groups of men participated in acute resistance and aerobic training. To know each subject`s VO2max, 8 each healthy male college students performed graded exercise test using bruce protocol and then four subjects performed resistance training which consist of three sets of six exercises at 60% of each subject`s one repetition maximum with a work of 300㎉ for 47min bout and other four subjects performed aerobic training, 24min bout of treadmill running to consume 300㎉ at matched rates of 60% VO2max. Blood was obtained at rest and immediately after and 30min, 60min after exercise for analysis of total epinephrine, cortisol, growth hormone, lactate and free fat acid. EPOC, RER, energy consumption and VO2 was measured continuously during exercise and the first 5min into recovery, 10min, 15min, 20min, 30min, 45min and at 60min into recovery. VO2 during resistance training(6.80ml/kg/min) and aerobic training(9.80ml/kg/min) were increased immediatry after exercise(p<.001) and then gradually decreased until value of rest, respectively. Total excess post-exercise oxygen consumption(97.48ml/kg/min) during resistance training and aerobic training(108.25ml/kg/min) were not significantly(p>.05) different whereas total energy consumption during resistance training(107.25㎉/min) and aerobic training (111.43㎉/min) were significantly(p<.05) different Respiratory exchange rate of resistance training(0.82) is lower than that of aerobic training(0.88). The period of epinephrine level in resistance exercise(58.63pg/ml) and that of aerobic exercise(73.22pg/ml) were increased immediatey after exercise(p<.001) and then gradually decreased untill value of rest, respectively. also, the period of norepinephrine level in resistance exercise(392.70pg/ml) and that of aerobic exercise(445.40pg/ml) were similiar pattern(p<.001) in that of resistance exercise(58.63pg/ml) and that of aerobic exercise(73.22pg/ml) as above. The period of growth hormone level in resistance exercise(9.84pg/ml) and that of aerobic exercise(8.71pg/ml) were increased immediatey after exercise(p<.001) and then gradually decreased until value of rest, respectively. FFA during aerobic training(370.90μEq/l) were increased 30min after exercise(p<.001) and then gradually decreased untill value of rest, respectively. There are a significant difference among period of lactate level in resistance exercise(4.46mmol/l) but not a significant difference among period of lactate level in aerobic exercise(2.74mmol/l). The period of glucose level in resistance exereise(58.63pg/ml) and that of aerobic exercise(73.22pg/ml) were increased immediatey after exercise(p<.001). The results suggest that, in general, aerobic training elicit a greater elevated total post-exercise oxygen consumption, total energy consumption, oxygen consumption, and epinephrine and free fat acid than resistance training when two activites are perforemed at mached 300㎉ energy consumption of work and equal duration whereas resistance training elicit a greater elevated lactate, growth hormone and RER. Therefore, RER as consequence of resistance training will be overemphasized if based on exercise for oxidation of fats.
