지속적 및 간헐적 운동이 운동중과 운동후 에너지대사에 미치는 영향 = Effects of Moderate Intermittent Exercise and Continuous Exercise on Energy Metabolism during Exercise and Recovery

다국어 초록 (Multilingual 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%VO2R) 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(VO2), 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 VO2, 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 VO2 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.

[서론] 본 연구는 동일한 운동시간(45분)과 회복시간(45분)의 조건에서 지속적 및 간헐적 두 운동유형이 안정시와 운동중 및 운동후 회복기의 산소섭취량, 호흡교환율, 칼로리소비량 및 지방산화율에 미치는 차이를 규명하는데 목적을 두었다. [방법] 건강한 남자 대학생 9명을 대상으로 VO2max와 최대지방연소 운동강도(MFOEI)를 결정한 다음 60%VO2R의 운동강도에서 45분간 지속적 또는 15분 운동 3회와 15분 휴식 2회의 간헐적 운동조건에 무선적으로 배정하여 각각 안정시, 운동중 및 운동후 회복기의 에너지 대사변인을 측정하여 분석하였다. [결과] 안정시와 운동중의 에너지 대사변인은 두 운동조건 간에 모두 유의한 차이가 나타나지 않았다. 운동후 회복기에는 산소섭취량과 칼로리소비량이 간헐적 운동조건과 지속적 운동조건간에 유의한 차이가 나타났다(p=.005, p=.001). 호흡교환율과 지방산화율은 간헐적 운동조건과 지속적 운동조건간에 유의한 차이가 나타났다 (p=.003, p=.002). [결론] 60%VO2R의 강도에서 간헐적인 운동은 동일한 강도와 동일한 운동량의 지속적인 운동보다 EPOC를 증가시켜 전체 칼로리소비량을 높이는데 효과적이었다.
