dc.descriptionIntroduction: Aerobic training can be conducted using the maximum heart rate (HRmax) target zone. This type of training is relevant to improving aerobic fitness and can help Brazilian jiu-jitsu athletes maintain optimal performance during and between matches. However, due to the lack of specificity of the generic equations in systematizing the training, the values can be overestimated, because athletes show specific morphophysiological adjustments. Objective: The aim was to investigate the relationship between HRmax as estimated by means of formulas and HRmax as reached in graded exercise tests (GTX) in both the laboratory and the field. Methods: 13 male Brazilian jiu-jitsu athletes had their HRmax determined in GTX on the treadmill and in the field, and the HRmax was calculated based on FOX and TANAKA equations. Results: The HRmax value by the means equation FOX-HRmax (189 ± 6 bpm) was greater in comparison with the GTX (on treadmill: 183 ± 7 bpm; field test: 180 ± 10 bpm; p < 0.05). The equation TANAKA-HRmax (185 ± 4 bpm) showed higher values when compared to the field test (180 ± 10 bpm; p < 0.05). No differences were observed between TANAKA-HRmax and GTX on the treadmill (p > 0.05). The correlation observed was between FOX-HRmax and TANAKA-HRmax: (r = 0.99; p < 0.01). Conclusion: FOX-HRmax and TANAKA-HRmax tend to overestimate the results compared to GTX. Thus, HRmax equations should be used and analyzed with caution. Conducting GTX is recommended to establish accurate values of HR. © 2019, Springer-Verlag Italia S.r.l., part of Springer Nature.
