Post-exercise diaphragm shielding: A novel approach to exercise-induced diaphragmatic fatigue

In conclusion, both DFG (baseline-to-peak) and DF (baseline-to-bottom) achieve similar magnitudes during and after consecutive exercise-trials and are closely linked to RPE and oxygen uptake. This suggests that DF neither reflects impaired diaphragmatic function nor impairs exercise performance; rather it is likely to reflect post-exercise diaphragm shielding.
