The purpose of this study was to quantify intermittent training sessions using different types of exercise. Strength, sprint, and endurance sessions were performed until exhaustion. These sessions were quantified by the product of duration and heart rate (HR) (i.e., training impulse (TRIMP) and HR-zone methods), by the product of duration and rate of perceived exertion (RPE-based method), and a new method (work endurance recovery (WER)). The WER method aims to determine the level of exercise-induced physiological stress using the ratio of cumulated work - endurance limit, which is associated with the naparian logarithm of the ratio of work-recovery. Each session's effects were assessed using blood lactate, delayed onset muscle soreness (DOMS), RPE, and HR. Because sessions were performed until exhaustion, it was assumed that each session would have a similar training load (TL) and there would be low interindividual variability. Each method was used to compare each of the TL quantifications. The endurance session induced the higher HR response (p < 0.001), the sprint session the higher blood lactate increase (p < 0.001), and the strength session the higher DOMS when compared with sprint (p = 0.007). TLs were similar after WER calculations, whereas the HR- and RPE-based methods showed differences between endurance and sprint (p < 0.001), and between endurance and strength TL (p < 0.001 and p < 0.01, respectively). The TLs from WER were correlated to those of the HR-based methods of endurance exercise, for which HR was known to accurately reflect the exercise-induced physiological stress (r = 0.63 and r = 0.64, p < 0.05). In addition, the TL from WER presented low interindividual variability, yet a marked variability was observed in the TLs of HR- and RPE-based methods. As opposed to the latter two methods, WER can quantify varied intermittent exercises and makes it possible to compare the athletes' TL. Furthermore, WER can also assist in comparing athlete responses to training programs.
本研究的目的是对使用不同类型运动的间歇训练课程进行量化。进行力量、冲刺和耐力训练直至力竭。这些训练课程通过持续时间与心率（HR）的乘积（即训练冲量（TRIMP）和心率区间法）、持续时间与主观用力程度（基于RPE的方法）的乘积以及一种新方法（工作耐力恢复（WER））进行量化。WER方法旨在通过累积工作 - 耐力极限的比值来确定运动诱发的生理应激水平，该比值与工作 - 恢复比值的自然对数相关。使用血乳酸、延迟性肌肉酸痛（DOMS）、RPE和心率来评估每次训练课程的效果。由于训练课程进行至力竭，因此假定每次训练课程具有相似的训练负荷（TL）且个体间变异性较低。使用每种方法来比较每种TL量化结果。与冲刺训练相比，耐力训练引起更高的心率反应（p < 0.001），冲刺训练引起更高的血乳酸升高（p < 0.001），力量训练引起比冲刺训练更高的DOMS（p = 0.007）。在进行WER计算后，TL相似，而基于心率和RPE的方法在耐力和冲刺训练之间（p < 0.001）以及耐力和力量训练的TL之间（分别为p < 0.001和p < 0.01）显示出差异。WER得出的TL与耐力运动中基于心率的方法得出的TL相关，已知心率能准确反映运动诱发的生理应激（r = 0.63和r = 0.64，p < 0.05）。此外，WER得出的TL个体间变异性较低，但基于心率和RPE的方法得出的TL中观察到明显的变异性。与后两种方法不同，WER可以量化各种间歇运动，并能够比较运动员的TL。此外，WER还可以帮助比较运动员对训练计划的反应。
