摘要：The purpose of this study was to investigate the effects of 30-second all out sprint interval exercise (SIE) vs. moderate aerobic exercise (MA) on excess post-exercise oxygen consumption (EPOC). Six recreationally-trained males (age=23.3±1.4 yrs, weight=81.8±9.9 kg, height=180.8±6.3cm) completed a sprint interval exercise session consisting of three repeated 30-second Wingate cycling tests separated by four minutes (duration~11minutes) as well as a moderate aerobic exercise session consisting of 30-minute cycling at 60% heart rate reserve (HRR) in a random counterbalanced design. Baseline oxygen consumption (VO2) was determined by an average VO2 from the final five minutes of a 30-minute supine rest period prior to each trial. Following each protocol, VO2 was measured for 30-minutes or until baseline measures were reached. EPOC was determined by subtracting baseline VO2 from post-exercise VO2 measurements. Energy expenditure (kJ) was determined by multiplying kJ per liter of oxygen by the average VO2 during recovery. EPOC values were significantly higher in SIE (7.5±1.3 L) than MA (1.8±0.7 L). SIE produced a higher recovery caloric expenditure (156.9 kJ) compared to MA (41.0 kJ) and remained significantly elevated (p=.024) over resting levels during the entire recovery period (30 minutes) compared to MA (6 minutes, p=.003). The energy required to recover from three repeated maximal effort 30-second Wingate cycling tests was greater than 30-minutes of moderate aerobic exercise. Future studies should examine the chronic effects of maximal effort sprint training protocol on cardiovascular fitness and body composition.
