The purpose of this study was to compare energy expenditure (EE) of single-set and multiple-set resistance exercise protocols using indirect calorimetry. Twelve men and twelve women (age = 21.4 ± 1.3 years) performed a single-set (SS) and multiple-set (MS) resistance exercise protocol in random order. The subjects performed two protocols at 70% of their 1-repetition maximum. The protocols consisted of 5 upper-body exercises of either 1 or 3 sets per exercise performed in random order. Metabolic and cardiorespiratory data were recorded over the entire exercise session and during 5 minutes of recovery by a portable metabolic measurement system. Gross (167.9 ± 58.7 kcal) and net (88.3 ± 41.6 kcal) EE for the MS protocol were significantly greater (p < 0.001) than gross (71.3 ± 26.5 kcal) and net (36.3 ± 18.7 kcal) EE of the SS protocol. Conversely, there was no significant difference in the rate of EE between both protocols. Significant gender differences (p < 0.001) in absolute and relative EE were observed for both protocols where values in men were higher than women. Heart rate, respiratory rate, relative V[Combining Dot Above]O2, respiratory exchange ratio, and minute ventilation values were significantly higher during the MS than the SS protocol. The results of this study indicated that MS protocols yield greater metabolic and cardiovascular demands than SS protocols when the number of exercises performed is the same.
本研究的目的是使用间接量热法比较单组和多组抗阻训练方案的能量消耗(EE)。12名男性和12名女性(年龄 = 21.4 ± 1.3岁)以随机顺序进行单组(SS)和多组(MS)抗阻训练方案。受试者以其1次重复最大值的70%进行两种训练方案。训练方案包括5项上肢练习,每项练习进行1组或3组,顺序随机。通过便携式代谢测量系统在整个训练过程以及恢复的5分钟内记录代谢和心肺数据。MS训练方案的总能量消耗(167.9 ± 58.7千卡)和净能量消耗(88.3 ± 41.6千卡)显著高于SS训练方案的总能量消耗(71.3 ± 26.5千卡)和净能量消耗(36.3 ± 18.7千卡)(p < 0.)。相反,两种训练方案之间的能量消耗率没有显著差异。在两种训练方案中均观察到绝对和相对能量消耗存在显著的性别差异(p < 0.001),男性的值高于女性。在MS训练方案期间,心率、呼吸频率、相对摄氧量、呼吸交换率和分钟通气量值显著高于SS训练方案。本研究结果表明,当进行的练习数量相同时,MS训练方案比SS训练方案产生更大的代谢和心血管需求。
