Exercise-training has been shown to influence resting components of energy expenditure in lean and obese individuals. Moreover, experimental data suggest that the effect of training on these components could represent an acute effect of exercise. In this regard, the present study was undertaken to determine whether resting metabolic rate (RMR) and glucose-induced thermogenesis (GIT) could be modified depending on the delay elapsing between the last exercise session of a training program and calorimetric measurements. Eight trained individuals were tested 16 h after a 90-min exercise bout and following a 3-day interruption of training. A significant decrease in RMR (-6.6 percent, P less than 0.05) was observed in response to exercise cessation. On the other hand, an increased GIT was noted following the 3-day rest period and this effect was also statistically significant. These results show that short-term interruption of training can affect substantially RMR and GIT in trained individuals, indicating that the time elapsing since the last exercise session must be taken into account in the interpretation of the effects of physical training on both these parameters.
运动训练已被证明会影响瘦人和肥胖者静息状态下的能量消耗组成部分。此外，实验数据表明，训练对这些组成部分的影响可能代表运动的急性效应。在这方面，本研究旨在确定静息代谢率（RMR）和葡萄糖诱导的产热（GIT）是否会根据训练计划的最后一次运动与热量测量之间的时间间隔而发生改变。八名受过训练的个体在进行90分钟运动 bout 后16小时以及经过3天的训练中断后接受测试。观察到运动停止后RMR显著下降（-6.6%，P<0.05）。另一方面，在3天的休息期后，GIT增加，且这一效应在统计学上也具有显著性。这些结果表明，训练的短期中断会显著影响受过训练个体的RMR和GIT，这表明在解释体育训练对这两个参数的影响时，必须考虑自上次运动以来所经过的时间。
