- Abstract
Introduction: In order to determine the intensity of aerobic exercise the anaerobic threshold and the respiratory compensation are used as referential; respectively, these physiologic markers are, generally, located at 50% and 80% of the maximal oxygen uptake (VO2max). To compare the values to the percentages of 50, 60, 70 and 80%, calculated through the HRR and VO2R equations corresponding to the oxygen consumption obtained by direct method. Materials and Methods: The sample was composed by 11 men and 10 women: mean age, 21.43 ± 2.82 years, body weight, 64.86 ± 12.17kg; and stature, 170.05 ± 9.12cm, performing maximal treadmill test, and the oxygen consumption obtained by the metabolic analyzer. To determine the percentages, we have used the mean values corresponding to the studied intensities according to the respective interval time relative to the percentage of oxygen consumption. Results: The measured intensities showed significant difference (p > 0.05) for every reference values. The mean values calculate by HRR showed a tendency to underestimate the intensities, while the values calculated by VO2R showed a tendency to overestimate the intensities. Conclusion: Both intensity determination methods of aerobic training showed significative difference, but they need to be adjusted in the equations. Thus, it is recommended the use of HRR in the determination of the intensities.
