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.
