Acute Effect of Inspiratory Muscle Training on Peripheral Tissue Oxygenation Behavior in Individuals With COPD: A Randomized Crossover Study.

In the within‐group comparisons, only the IMT‐Endurance group showed a significant increase in StO 2 from baseline (55.62) to post‐intervention (56.76; p = 0.003), whereas the changes observed in the IMT‐Strength group (55.76–56.33; p = 0.133) and the Sham group (55.88–56.48; p = 0.115) did not reach statistical significance.
