Pursed Lips is a maneuver frequently used in respiratory rehabilitation programs, aiming to improve respiration efficacy and provide better control of dyspnea during the performance of activities of daily living. Respiratory sinus arrhythmia, is used often to assess vagal tone as it increases and decreases the parasympathetic influence when the autonomic nervous system is adequately balanced. In the exercise, the cardiac parasympathetic reactivation is the main determinant of the immediate fall of the heart rate when it ceases or the intensity diminishes. The purpose of this work was to investigate the influence of respiratory frequency in the reactivation of the parasympathetic system after a physical effort.
