This study was conducted to investigate the influence of fitness level and gradually increased amounts of exercise on individuals' ratings of perceived exertion (RPE). 20 men served as paid subjects. They were divided into groups of high ( > 56 ml/kg/min.) and low fitness ( < 46 ml/kg/min.) according to their maximal oxygen uptake (VO2 (max)). Participants were required to pedal on a cycle ergometer at a progressively increased workload (every 10 min.) corresponding to 40, 50, 60, 70, and 80% of individual VO2 (max) values. Heart rates, RPE, and core temperatures were recorded every 5th minute after the initiation of exercising at a specific workload. Analysis indicated that, when controlling for VO2 (max) values, elevations of heart rate and core temperature were not affected by fitness. However, highly fit individuals perceived themselves under less exertion than did the group low in fitness. Correlations showed that, taking into consideration fitness, there is a stronger relationship between RPE and heart rate and RPE and core temperature for the highly fit individuals than for the less fit.
本研究旨在调查健康水平和逐渐增加的运动量对个体主观用力感觉（RPE）评分的影响。20名男性作为有偿受试者。根据他们的最大摄氧量（VO2（max）），他们被分为高健康水平组（>56毫升/千克/分钟）和低健康水平组（<46毫升/千克/分钟）。参与者被要求在自行车测力计上以逐渐增加的工作量（每10分钟）蹬踏，对应于个体VO2（max）值的40%、50%、60%、70%和80%。在以特定工作量开始运动后，每隔5分钟记录心率、RPE和核心温度。分析表明，在控制VO2（max）值时，心率和核心温度的升高不受健康水平的影响。然而，健康水平高的个体比健康水平低的组感觉自己用力程度更低。相关性表明，考虑到健康水平，与健康水平较低的个体相比，健康水平高的个体的RPE与心率以及RPE与核心温度之间的关系更强。
