Stucky et al. ([5]) suggested that the resulting net Vbs into the trunk throughout exercise in EFLe was attributed to a greater inspiratory blood flow into the trunk compared to the expiratory blood flow towards the periphery. Hyperinflation is an additional consequence of EFLe, developing in 50% of total runs in Stucky et al. ([5]), which might lead to increased inspiratory muscle blood flow as a result of a higher inspiratory muscle metabolic demand.
