The session rate of perceived exertion method (sRPE) has often been utilized in sports activities in which quantification of external training loads is challenging. The multi-modal, constantly varied nature of high intensity functional training (HIFT) represents a significant hurdle to calculate external work and the sRPE method may provide an elegant solution to this problem. However, no studies have investigated the psychometric properties of sRPE within HIFT interventions. Twenty-five healthy men and women participated in six weeks of HIFT. Rate of perceived exertion and heart rate were assessed within every training session throughout the duration of the intervention. Compared to criterion heart rate-based measures, we observed sRPE method is a valid tool across individual, group, and sex levels. However, poor reliability in participants' abilities to correctly match rate of perceived exertion with the relative level of physiologic effort (i.e., percentile of maximum heart rate) currently limits the utility of this strategy within HIFT. When applied, the validity and reliability of the sRPE seem to improve over time, and future research should continue to explore the potential of this monitoring strategy within HIFT interventions.
自感用力度法（sRPE）常用于外部训练负荷量化具有挑战性的体育活动中。高强度功能性训练（HIFT）具有多模式、不断变化的特点，这给计算外部工作量带来了重大障碍，而sRPE方法可能为解决这一问题提供一个简洁的方案。然而，尚无研究调查过sRPE在HIFT干预中的心理测量特性。25名健康男性和女性参与了为期六周的HIFT。在整个干预期间，每次训练课都对自感用力度和心率进行评估。与基于标准心率的测量方法相比，我们观察到sRPE方法在个体、群体和性别层面都是一种有效的工具。然而，参与者将自感用力度与生理努力相对水平（即最大心率百分比）正确匹配的能力可靠性较差，这目前限制了该策略在HIFT中的应用。应用时，sRPE的有效性和可靠性似乎会随着时间的推移而提高，未来的研究应继续探索这种监测策略在HIFT干预中的潜力。
