HR_DB: heart rate response to deep breathing; BRS_VM: baroreflex sensitivity obtained by Valsalva maneuver; BRS_seq: baroreflex sensitivity obtained by the sequence method; LF: low frequency; HF: high frequency; FVC: forced vital capacity; FEV1: forced expiratory volume in one second; MIP: maximum inspiratory pressures; MEP: maximum expiratory pressures; RMT: respiratory muscle training.
