Background: The autonomic nervous system (ANS) controls the airway caliber and a dysfunction of this system can contribute to the progressive worsening of asthmatic patients. Pulmonary rehabilitation programs are part of non-drug treatment for patients with pulmonary disease, however, the effects of resistance exercise and autonomic modulation are still unknown subjects in asthmatic patients. Aim: The aim of the study was to investigate the influence of resistance training on heart rate variability (HRV) in individuals with difficult-to-control asthma. Methods: The experimental protocol consisted of an initial and final evaluation: body composition, spirometry, exhaled Nitric Oxide (eNO) HRV evaluation (supine and stand positions), 1RM of the quadriceps femoris, hamstrings, pectoralis, latissimus dorsi, biceps and triceps and asthma control questionnaire (ACQ6). After the evaluations, the patients underwent resistance training for 12/week, with an intensity of 60-80% of 1RM, 3 series of 12 repetitions with a 5% increase in load weekly according to the patient9s tolerance. Results: Twenty-one clinical stable patientes were included in this study (aged 39.5±13.9), eNO (37.5±35.6). After the resistance training, there was improvement in ANS activity and supine-vagal balance in supine position LF: 39.2±17.8 / 19.8±5.9nu (p Conclusion: Patients with DTC asthma showed improved autonomic modulation after resistance training protocol.
