The sedentary lifestyle stands out as one of the main risk factors related to CVD. It is essential that a thorough evaluation is carried out in order to prescribe in a proper manner, respecting the biological individuality. Cardiopulmonary exercise test (CPT) is a useful tool in determining functional capacity. The ventilatory anaerobic threshold (AT) is shown as an important parameter for exercise prescription. The gold standard method for obtaining AT is visual analysis of the curves obtained from the ventilatory variables of the CPT. However, analysis of heart rate (HR) response appears as a promising strategy as a useful, simple and low-cost tool for determining AT. Objective: To evaluate the validity of the LAV determination through the HR response during the CPT. Methods: Men and women were recruited, aged over 18 years and who presented risk factors for CVD. All volunteers underwent a clinical evaluation and the CPT by means of an incremental power protocol (10W/min) until physical exhaustion. The AT was determined by the graphical visual method and by the heteroscedastic statistical model, where the variables time, power, HR and oxygen consumption (VO2) were analyzed. Results: No significant differences were found in VO2 (mL/ kg/min), VO2 (L/min) and power (W) values, comparing the determined methods. In addition, for all variables, strong and strong correlations were found. Conclusion: The determination of LAV by the HR response proved to be an adequate model.
