Several studies suggest that inspiratory muscle warm-up (IMW) could potentially affect exercise performance; however, its mechanistic basis is still unclear. The aim of this study was to examine the effect of IMW on lung diffusing capacity for carbon monoxide, cardiorespiratory, perceptual and performance outcomes in elite athletes from different disciplines. The aim of this study is to evaluate the effects of IMW on diffusion capacity for carbon monoxide, cardiorespiratory, perceptual and performance outcomes during high-intensity exercise in elite athletes from different disciplines. The study will be conducted using a randomized, placebo-controlled, double-blind and crossover study experimental design involving 35 athletes from various sports disciplines, including endurance, strength, skill-based, and mixed disciplines. Participants will attend the laboratory on four separate occasions. During the first visit, they will be informed about the study and familiarized with the application and measurement procedures. In the second visit, a general warm-up will be performed. During the third and fourth visits, IMW (IMW40% or IMW placebo) protocols will be applied in addition to the general warm-up. Measurements of DLCO, pulmonary function tests, respiratory muscle strength, and gas analysis during maximal aerobic exercise will be collected both before and after the warm-up protocols.
