Maximal Respiratory Pressures and Maximum Voluntary Ventilation in Young Arabs: Association with Anthropometrics and Physical Activity.

33 MIP, MEP, and PFT values (FVC, FEV1) showed a moderately significant relationship, which is consistent with previous research that found a strong correlation between MRPs and FVC and FEV1. 25 , 33 MIP, MEP, and FEV1, FVC in COPD patients showed a highly significant correlation with a positive linear trend. 26 MIP and MEP had a moderate relationship (r= 0.27, p=0.01) with MVV, which is consistent with a study by Pradeep Kumar et al, who found the highest correlation between MVV and MRPs. 26 Because these two factors are linked, respiratory muscle endurance measured by MVV may have a direct impact on respiratory muscle strength measured by MIP and MEP.
