Résumé
Background
This study investigated the effects of three doses of caffeine (CAF) on hematological and biochemical responses during the CrossFit® workout, a protocol known to induce significant physiological fluctuations.
Methods
In a randomized, double-blind, placebo (PLA)-controlled crossover trial, 26 moderately trained CrossFit® athletes received acute doses of 3, 6, or 9 mgCAF/kgbody mass (BM), or a PLA, 70 min before a 17-min CrossFit® workout.
