Little is known about the effect of non-steady state resistive exercise on postexercise energy expenditure. Using a counterbalanced design, energy expenditure was measured by indirect calorimetry in six adult males (mean age +/- SD = 24.5 +/- 6.1) for 30 min before and 60 min after a single 42 min bout of weight lifting, and again on a separate day for 30 min before and 60 min after a 42 min control period of quiet sitting. For the exercise condition the subjects performed 4 sets of upper and 3 sets of lower body resistive exercises at weights equivalent to a 12 repetition maximum for each respective lift. Metabolic rate remained significantly elevated at the end of the 60 min recovery period compared to the control condition, although the excess postexercise oxygen consumption accounted for only approximately 19 additional kcal expended. These data suggest that while postexercise metabolic remains elevated for at least one hour following a moderate level of resistive exercise, the caloric cost of this elevation during a one hour recovery period is small and similar to that induced by steady-state exercise of moderate intensity.
关于非稳态阻力运动对运动后能量消耗的影响，人们所知甚少。采用平衡设计，通过间接测热法测量了6名成年男性（平均年龄±标准差=24.5±6.1岁）在单次42分钟举重 bout 前后30分钟以及在单独一天的42分钟安静坐姿对照期前后30分钟的能量消耗。在运动条件下，受试者进行了4组上肢和3组下肢阻力运动，每组运动的重量相当于各自最大重复次数为12次时的重量。与对照条件相比，在60分钟恢复期结束时代谢率仍显著升高，尽管运动后过量耗氧量仅额外消耗了约19千卡能量。这些数据表明，虽然在中等强度的阻力运动后运动后代谢至少会升高一小时，但在一小时恢复期内这种升高所产生的热量成本很小，且与中等强度稳态运动所引起的热量成本相似。
