Abstract:
This study examined the effects of caffeine intake on physical and cognitive performance during specific training sessions. The sample included 28 subjects, divided into two groups: a caffeine group (n=16), which consumed 300 mg of caffeine before training, and a placebo group (n=12), which received an inert substance. The variables analyzed included maximal strength (1RM), explosive power of the lower extremities (vertical jump), sprint endurance, time to exhaustion, and reaction time. The results showed statistically significant improvements in performance in the caffeine group compared to the placebo group (p < 0.05). The mechanisms of action of caffeine include inhibition of adenosine receptors, stimulation of catecholamines, and increased energy mobilization. These findings suggest that controlled use of caffeine can improve athletic performance, especially in sports that require repetitive high-intensity efforts. Future research should focus on individual variations in the response to caffeine and the long-term effects of its use.
