This study assessed the relationship of the rating of perceived exertion (RPE) with heart rate and pacing strategy during competitive running races of differing distance and course elevation. Nine men and women competed in a 7-mile road race (7-MR) and the Great West Run half marathon (GWR; 13.1 miles). Heart rate, split mile time, and RPE were recorded throughout the races. The RPE was regressed against time and %time to complete the 7-MR and GWR. Although the rate of increase in RPE was greater in the 7-MR, there were no differences when expressed against %time (inferring that the brain uses a scalar timing mechanism). As the course elevation, distance, pacing strategy, and heart rate response varied between conditions, this study has provided evidence that the perceptual response may have distinct temporal characteristics during distance running. The results provide further evidence that RPE scales with the proportion of exercise time that remains.
本研究评估了在不同距离和赛道海拔的竞争性跑步比赛中，自感用力度（RPE）与心率及配速策略之间的关系。九名男性和女性参加了一场7英里公路赛（7-MR）和大西部半程马拉松赛（GWR；13.1英里）。在整个比赛过程中记录心率、每英里分段时间和RPE。将RPE与完成7-MR和GWR的时间及时间百分比进行回归分析。尽管7-MR中RPE的增加速率更大，但以时间百分比表示时并无差异（这意味着大脑使用了一种标量计时机制）。由于不同条件下赛道海拔、距离、配速策略和心率反应各不相同，本研究提供了证据表明，在长跑过程中，感知反应可能具有不同的时间特征。结果进一步证明，RPE与剩余运动时间的比例成比例。
