简要总结
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.

结局指标
主要结局
Maximal inspiratory pressure
时间窗: Immediately before intervention, immediately after intervention, 15 minutes post intervention and 30 minutes post intervention
It will be assessed using a Breathare MIP/MEP® (GH Innotek Co., Ltd., Busan, Republic of Korea).The Breathare MIP/MEP® is likely a respiratory pressure meter or manometer designed for measuring respiratory muscle strength. It typically includes a mouthpiece connected to a pressure sensor, and the device measures the force or pressure generated during respiratory maneuvers. The person will be instructed to take a maximal deep breath in, and then exhale to residual volume. After that, they will be asked to inhale forcefully against the resistance provided by the Breathare MIP/MEP®. This measures the strength of the inspiratory muscles. The measures will be expressed in cmH2O.
