Inspiratory muscle warm up improves 400 m performance in elite male runners.

ABSTRACT: This study sought to establish an optimal inspiratory warm-up (IWU) protocol for elite 400-meter athletes. It addresses the existing gap in sprint-specific research and provides practical applications for coaches and athletes aiming to optimize sprint running performance. Across four weeks, 13 elite male runners (age: 22.7 ± 2, personal best: 50.78 ± 0.65 s) performed four 400-meter time trials after different warm-up protocols in a randomized order. Assessments of various respiratory variables [maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), peak inspiratory flow rate (PIFR), inhaled volume (IV)] and selected physiological indices [heart rate (HR) and blood lactate (bLa)] were performed before and after the time trials. Analysis of variance with a significance level
