Resumen:	Background: Nutritional ergogenic aids are foods or nutrients that can improve physical performance. Among these foods with ergogenic properties, cafeine has shown that it can increase the fat catabolism, strength, and improve the cognition and time reaction of an athlete, therefore, it is hoped that it can improve the performance of judokas. This study through a double-blind crossover (supplement X placebo) protocol, investigated the efects cafeine supplementation (single capsule containing 5 mg/kg body mass intake 60 min before the session) on biochemical, anthropometrical, physical, subjective and hemodynamic variables measured before, during and after two typical judo training cxs sessions (120-min: 40-min of gymnastics; 40-min of specifc technics and; 40-min of judo combat). Methods: 8 high-level athletes (21.4±2.0 years; 83.6±15.2 kg; 1.8±0.1 m; 17.9±7.0 Fat%) were evaluated before and after each training for body mass, hydration, upper and lower limb power, performance in the special judo ftnesstest (SJFT), free fatty acids (FFA) in plasma, uric acid, glucose, lactate, heart rate, and pain. In addition, heart rate, FFA in plasma, uric acid, glucose, lactate, rating of perceived exertion and pain were assessed during the training. Results: At 120 min, supplementation resulted in a higher concentration of plasma FFA (1.5±0.5 vs. 1.0±0.3 mmol/L; p=0.047) and lactate (4.9±1.8 vs. 3.0±1.2 mmol/L; p=0.047), and a lower concentration of uric acid (5.4±0.9 vs. 7.0±1.5 mg/dL; p=0.04). Supplementation also resulted in performance maintenance (fatigue index) in the SJFT (Δ0.3±2.0 vs Δ1.7±2.5, for cafeine and placebo respectively, p=0.046). No adverse efects were observed. Conclusion: Based on the applied dose, intake time, and sample of this study, we can conclude that cafeine pro‑ duces an ergogenic biochemical efect, and improves performance in judo athletes.
