Is respiratory muscle performance related to oxygen kinetics during maximal exercise and early recovery in patients with congestive heart failure?
Respiratory muscle fatigue (reduction in Pi(max)) after exercise is linked to delayed oxygen kinetics recovery, contributing to exercise intolerance in CHF patients.
The reduction of Pi(max) after exercise is associated with prolonged early recovery of oxygen kinetics, which may explain, in part, the role played by respiratory muscles in exercise intolerance in CHF patients.
Nanas et al. (Tue,) studied this question.
