SANTOS, Tony Meireles; VIANA, Bruno Ferreira  and  SA FILHO, Alberto Souza. Reprodutibilidade do VO_2Máx estimado na corrida pela frequência cardíaca e consumo de oxigênio de reserva. Rev. Bras. Educ. Fís. Esporte [online]. 2012, vol.26, n.01, pp.29-36. ISSN 1981-4690.

The objective was to determine the reliability of the VO_2Max estimate on a treadmill using the measured (HR_peak) vs. the predicted (HR_predicted) maximum heart rate (HR). Eighteen men (27.5 ± 7.1 years, 73.7 ± 12.6 kg, 174.8 ± 10.2 cm) performed, in the fi rst visit, a progressive test to determine the HR_peak. In the two following visits, submaximal aerobic tests were performed on a treadmill with a 6 min at 75% HR reserve. VO_2Max was estimated by means of the equations of HR, VO2 reserve and the ACSM running equation. The intraclass correlation coeffi cient and the typical error of measurement using HR_Predicted and HR_peak were 0.89, 2.43 ml.kg-1.min-1 (5%) and 0.83, 2.43 mL.kg-1.min-1 (4.9%), respectively. There was no signifi cant difference (t test) between the estimates of VO_2Max from the HR_peak and HR_predicted. The use of the HR_predicted was considered appropriate for VO_2Max estimation, with a small typical error of measurement.
