Abstract

The purpose of this study was to assess the effects of varied rest intervals, following a 5-min warm-up, upon subsequent ratings of perceived exertion, heart rate (HR), and state anxiety during an exercise period. The subjects were 16 male college students, each with predicted [Vdot]O max of at least 51 ml/kg/min (X = 54.4) as determined by the åstrand bicycle test. Each subject was tested under four experimental conditions following a 5-min warm-up on a bicycle ergometer at 75% of HR max. Rest intervals of 1 min, 5 min, 10 min, and no rest preceded a progressively increasing 8-min exercise period on a bicycle ergometer. Ratings of perceived exertion (RPE), heart rate, and state anxiety were obtained at 1, 000, 1, 200, 1, 400, and 1, 600 KPM during each of the experimental conditions. An analysis of variance, four by four factorial design with repeated measures on both factors, was used to determine if significant differences existed between the experimental conditions for RPE and HR. An analysis of variance, treatment by subjects design, was used to determine if there were significant differences in state anxiety levels among the experimental conditions. Intraclass correlations revealed that reliability for HR and RPE was extremely high. No significant difference was found among the four experimental conditions for perceived exertion, heart rate, and state anxiety. RPE was found to be a good predictor of physiological strain as indicated by HR. © 1977 Taylor 8 Francis Group, LLC. 2
