This study investigated the effect of inspiratory muscle strength training (IMST) on inspiratory motor drive (P0.1) and respiratory related evoked potentials (RREP). It was hypothesized that if IMST increased inspiratory muscle strength, inspiratory motor drive would decrease. If motor drive was related to the RREP, it was further hypothesized that an IMST-related decrease in drive would change RREP latency and/or amplitude. Twenty-three subjects received IMST at 75% of their maximal inspiratory pressure (MIP) using a pressure threshold valve. IMST consisted of 4 sets of 6 breaths daily for 4 weeks. P0.1 and the RREP were recorded before and after IMST. Post-training, MIP increased significantly by 36.0±2.7%. P0.1 decreased significantly by 21.9±5.2%. The increase in MIP was significantly correlated to the decrease in P0.1. RREP peaks P1a, Nf, P1, and N1 were identified pre- and post-IMST and there was no difference in either amplitude or latency for those peaks. These results demonstrate that high-intensity IMST significantly increases MIP, decreased P0.1, but did not change the RREP.
