Sex differences in the acute effect of caffeine on repeated sprint performance: A randomized controlled trial.

ABSTRACT: This study aimed to examine sex differences in acute caffeine intake on repeated sprint performance. Fifty-two resistance-trained individuals (age: 24.6 ± 4.5 years and sex (female/male): 26/26) participated in a randomized, triple-blind, cross-over, and placebo-controlled study. Participants ingested 3 mg/kg caffeine or placebo and, after 60 min, performed 4 Wingate tests (Wt), consisting of a 30 s all-out lower-body sprint against an individualized resisted load, with 90 s rest periods between sprints. Mean (W_mean) and peak (W_peak) power showed an interaction between sprint and supplement (P = 0.038, η_p ² = 0.095 and P < 0.001, η_p ² = 0.157, respectively), but only W_peak reported a supplement and sex interaction
