Reference factor for independent variables are marked with (+). Results are reported as beta coefficient (standard error);
*
p < .05,
**
p < .01. RT: respiratory training; FVC: forced vital capacity; FEV 1: forced expiratory volume in one second;
BS: baroreflex sensitivity; MEP: maximum expiratory pressure generation.
