Tucker, WJ, Angadi, SS, and Gaesser, GA. Excess postexercise oxygen consumption after high-intensity and sprint interval exercise, and continuous steady-state exercise. J Strength Cond Res 30(11): 3090-3097, 2016-Higher excess postexercise oxygen consumption (EPOC) after high-intensity interval exercise (HIE) and sprint interval exercise (SIE) may contribute to greater fat loss sometimes reported after interval training compared with continuous steady-state exercise (SSE) training. We compared EPOC after HIE, SIE, and SSE. Ten recreationally active men (age 24 ± 4 years) participated in this randomized crossover study. On separate days, subjects completed a resting control trial and 3 exercise conditions on a cycle ergometer: HIE (four 4-minute intervals at 95% peak heart rate (HRpeak), separated by 3 minutes of active recovery), SIE (six 30-second Wingate sprints, separated by 4 minutes of active recovery), and SSE (30 minutes at 80% of HRpeak). Oxygen consumption (V[Combining Dot Above]O2) was measured continuously during and for 3 hours after exercise. For all conditions, V[Combining Dot Above]O2 was higher than resting control only during the first hour postexercise. Although 3-hour EPOC and total net exercise energy expenditure (EE) after exercise were higher (p = 0.01) for SIE (22.0 ± 9.3 L; 110 ± 47 kcal) compared with SSE (12.8 ± 8.5 L; 64 ± 43 kcal), total (exercise + postexercise) net O2 consumed and net EE were greater (p = 0.03) for SSE (69.5 ± 18.4 L; 348 ± 92 kcal) than those for SIE (54.2 ± 12.0 L; 271 ± 60 kcal). Corresponding values for HIE were not significantly different from SSE or SIE. Excess postexercise oxygen consumption after SIE and HIE is unlikely to account for the greater fat loss per unit EE associated with SIE and HIE training reported in the literature.
塔克，WJ，安加迪，SS，以及盖泽尔，GA。高强度和冲刺间歇运动以及持续稳态运动后的运动后过量氧耗。《力量与体能研究杂志》30(11): 3090 - 3097，2016年 - 与持续稳态运动（SSE）训练相比，高强度间歇运动（HIE）和冲刺间歇运动（SIE）后更高的运动后过量氧耗（EPOC）可能是导致有时报道的间歇训练后脂肪减少更多的原因。我们比较了HIE、SIE和SSE后的EPOC。十名有运动习惯的男性（年龄24±4岁）参与了这项随机交叉研究。在不同的日子里，受试者完成了一次静息对照试验以及在功率自行车上的三种运动条件：HIE（以95%的心率峰值（HRpeak）进行四个4分钟的间歇，中间间隔3分钟的主动恢复）、SIE（六次30秒的温盖特冲刺，中间间隔4分钟的主动恢复）和SSE（以HRpeak的80%进行30分钟运动）。在运动期间及运动后3小时持续测量耗氧量（V̇O₂）。对于所有条件，V̇O₂仅在运动后的第一小时高于静息对照。尽管与SSE（12.8±8.5升；64±43千卡）相比，SIE（22.0±9.3升；110±47千卡）后的3小时EPOC和运动后总净能量消耗（EE）更高（p = 0.01），但SSE（69.5±18.4升；348±92千卡）的总（运动 + 运动后）净耗氧量和净EE比SIE（54.2±12.0升；271±60千卡）更大（p = 0.03）。HIE的相应值与SSE或SIE没有显著差异。SIE和HIE后的运动后过量氧耗不太可能解释文献中报道的与SIE和HIE训练相关的每单位EE更大的脂肪减少。
