Based on scores from a maximal exercise test on a bicycle ergometer, 24 college-age women were classified into three aerobic-fitness groups. Each subject then completed two randomly ordered cycle exercise bouts at 1-wk. intervals. The exercise bouts required the subjects to pedal for 24 min. attaining and then maintaining a target heart rate of either 30% or 60% of heart-rate reserve. Ratings of perceived exertion (RPE) were reported at the end of each third minute of the exercise period. Repeated-measures analysis of variance indicated the RPE was significantly related to the exercise workload and duration of exercise. No main effect was found for fitness. Two-way interactions were detected for fitness x duration of exercise and for workload x duration of exercise.
根据在自行车测力计上进行的最大运动测试得分，24名大学年龄女性被分为三个有氧适能组。然后，每位受试者每隔1周完成两次随机排序的循环运动 bout。运动 bout 要求受试者蹬踏板24分钟，达到并保持心率储备的30%或60%的目标心率。在运动期的每三分钟结束时报告自觉用力程度（RPE）评分。重复测量方差分析表明，RPE与运动工作量和运动持续时间显著相关。未发现适能的主效应。检测到适能×运动持续时间和工作量×运动持续时间的双向交互作用。
