This study aims to examine the effects of inspiratory muscle warm-up (IMW) on the gas exchange capacity of the lungs (DLCO) and its potential contribution to recovery and athletic performance in elite athletes from various disciplines. The study hypothesizes that the decline in respiratory muscle capacity following high-intensity exercise, which negatively affects ventilation, diffusion, and oxygen transport, may be ameliorated through specific IMW protocol. A placebo-controlled, randomized, crossover, and double-blind design will be utilized, involving 28 elite male athletes from endurance, power, skill-based, and mixed disciplines.
Participants will complete three warm-up protocols: General Warm-up (GW), General Warm-up combined with IMW at 40% resistance intensity (GW+IMW40%), and a placebo condition (GW+IMWplacebo). Measurements will include respiratory muscle strength, DLCO (assessed at post-2, 30, 60, 90, and 120 minutes), respiratory function, and cardiorespiratory parameters during maximal exercise. This study is unique as it aims to detail the micro-level effects of IMW on pulmonary diffusion mechanisms and performance outcomes, providing novel insights into the ameliorative effects of IMW on respiratory function post-exercise. Additionally, it seeks to expand understanding of the mechanistic basis of IMW's benefits on both pulmonary diffusion capacity and athletic performance.
