About this trial
This randomized controlled trial investigates the acute effects of inspiratory muscle warm-up and fatigue on diaphragmatic function in professional basketball players. Using ultrasound imaging and maximal inspiratory pressure (PIM) assessment, the study evaluates changes in diaphragmatic thickness and respiratory strength before and after specific inspiratory muscle loading protocols. Findings aim to clarify the short-term impact of these interventions on diaphragmatic recovery capacity, with potential implications for respiratory training, performance enhancement, and injury prevention strategies in elite athletic populations.
