The aim of this study was to compare the maximal heart rate (HRmax) in the Bruce test (TBruce) at different times of the day, since several measurements of the human performance present circadian variations which seem to follow the body temperature rhythm. Eleven male individuals, with 22.0 ± 1.6 years, physically active and from the intermediate chronotype were studied. The resting HR (HRres), maximal HR (HRmax), perceived exertion (PE) and time until exhaustion (TBruce) were observed. The Polar Vantage NV cardiofrequencymeter was used in order to measure the HR. The PE was obtained through the Borg's scale (6-20). The protocol by Bruce for treadmill was applied until exhaustion, at 6 different times: 9:00; 12:00; 15:00; 18:00; 21:00 and 2...
