BACKGROUND Exercise capacity is reduced in obese patients due to disadvantageous respiratory mechanics that lead to dyspnea. Proportional assist ventilation (PAV) has the potential to unload resistive and elastic burdens of the ventilatory system. OBJECTIVES The present study aimed to test if PAV can increase endurance and reduce exercise-related dyspnea(More)
Based on the "post-exercise diaphragm shielding" hypothesis this study tested whether both diaphragmatic force-generation (DFG) and diaphragmatic fatigue (DF) remain unchanged during consecutive exercise-trials. Twelve subjects (V(O2 max) 58.4+/-6.6 ml kg(-1) min(-1)) performed three consecutive exercise-trials (T(alpha)/T(beta)/T(gamma); workload(max) 85%(More)
