Was analyzed the Heart Rate (HR) behavior and identified the HR inflection points (HRIP) and deflection points (HRDP) in a maximum progressive test, using female and male subjects. Twenty university students were submitted to a maximum progressive test. The HR was monitored to posterior analysis and identification of the transition points (TP). The subjects' HR showed sigmoid behavior, with TP identification in all subjects, being: a) in 65% HRIP (64 ± 27W; 29 ± 9% Pmax and 126 ± 12bpm; 66 ± 5% HRmax) and HRDP (177 ± 45W; 81 ± 10%Pmax and 178 ± 8bpm; 93 ± 4%Hrmax); b) in 30% only the HRIP (80 ± 32W; 36 ± 14%Pmax and 125 ± 13bpm; 66 ± 5%HRmax) and c) in 5% HRDP isolated (103W; 57%Pmax and 150bpm; 82%HRmax). The HRIP was found in significantly lower load than HRDP and there were no differences in the load and HR relative between genders.
