Psycho-physical Effects Of Varied Rest Intervals Following Warm-up.
Published 1977 · Psychology, Medicine
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]O2 max of at least 51 ml/kg/min ( = 54.4) as determined by the Astrand 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 ...
