| Abstract |
INTRODUCTION
The purpose of this study was to compare the energy metabolism between 'intermittent exercise group' and 'continuous exercise group' of same intensity(60%VO 2 R) total exercise duration(45min) and total exercise recovery period(45min).
METHOD
Nine healthy university students participated in two trials: (1) a single 45min bout exercise (continuous) and (2) three 15min bouts of exercise separated by a 15min rest (intermittent). Each exercise was performed with a treadmill at 60% oxygen uptake reserve.
RESULT
During the rest, no significant difference was observed in oxygen uptake(VO 2 ), respiratory exchanged ratio(RER), exercise expenditure(EE) and fat oxidation rate(FOR) between the intermittent and continuous trails. During the exercise, no significant difference was observed in VO 2 , RER, EE, FOR between the intermittent and continuous trails. However, the RER and FOR values during the recovery period were significaltly lower in the intermittent trial than in the continuous trial(p=.003, p=.002), and the VO 2 and EE values during the recovery period were significantly higher in the intermittent trial than in the continuous trial(p=.005, p=.001), respectively.
CONCLUSION
These results suggest that the moderate intermittent exercise can contribute to greater exercise-induced energy expenditure compared with a moderate continuous exercise. |
