The aim of this study was to estimate and compare energy expenditure and blood lactic acid in a 30min continuous bout of bicycle ergometer cycling at 80% of HRmax reserve with 45 min of recovery and in 10 min intermittent bouts of exercise with equally divided into three 15min periods of recovery. Subjects were fourteen college-aged males(age: 22±1.8 years, height: 173±6.5 cm, weight: 70±13.8 kg, %body fat: 19±6.5%) volunteered to participate. Energy expenditure was measured with the POLOR(RS 800CX, Finland) & exercise record/analysis program and Lactate Tester (YSI 1500, USA), at warm up, exercise and during recovery. The 30 min continuous bouts of exercise included a 45 min recovery and each of the three 10 min bouts included 15 min of recovery. Workload was adjusted during exercise to maintain at 80% target HR. Setting of target HR was at 1/3 position of main exercise and maintaining to the end of the exercise. Differences in energy expenditure between continuous and intermittent exercise, recovery from exercise, as well as the combination of exercise an recovery were assessed with a paired t-test. And blood lactic acid concentration were analysis with independent t-test and oneway repeated measures ANOVA were employed to analyse blood lactatic acid. Significance was set a p<.05. The energy expenditure for exercise only was no significantly greater(6.3 kcal) with continuous bout of exercise than intermittent bouts of exercise. On the other hand, during recovery from exercise, they expended more energy(22.7 kcal) following intermittent exercise than following continuous exercise. The total energy expenditure for the combination of exercise and recovery was greater(16.3 kcal) than intermittent bouts of exercise, but it was not significant. And on blood lactic acid, there is significant different at point of exercise finish and at 15min of recovery(p<.01, p<.05 respectively).
