24 females (aged 18 to 28 yr.) completed two 24-min., randomly ordered bicycle ergometer exercise bouts at workloads maintaining steady state at 30% and 60% heart-rate reserve. Ratings of perceived exertion (RPE) were recorded at 3-min. intervals from Minutes 9 to 24 of exercise. State anxiety was measured prior to, immediately following and 50 min, after cessation of exercise. Regression analysis indicated no relationship between RPE and the pre- to postexercise changes in state anxiety.
24名女性（年龄在18至28岁之间）完成了两次24分钟的自行车测力计运动，运动顺序随机，运动强度分别维持在心率储备的30%和60%以保持稳定状态。在运动第9分钟至24分钟期间，每隔3分钟记录一次自觉用力程度（RPE）。在运动前、运动结束后即刻以及运动结束后50分钟测量状态焦虑。回归分析表明，RPE与运动前后状态焦虑的变化之间没有关系。
