The aim of this study was to examine the effect of acute caffeine supplementation on performance and physiological variables in recreationally physically active men. Methods: The sample consisted of 34 male subjects, aged 20 to 30 years, who were randomly divided into an experimental group that received caffeine (n = 16) and a placebo control group (n = 18). Initial and final measurements of aerobic endurance (beep test), explosive strength of the lower extremities (CMJ), maximum strength of the upper body (1RM bench press), reaction time, heart rate, blood pressure and perceived exertion (RPE) were performed on the subjects. Analysis of variance (ANOVA) was used to process the data, with the statistical significance level set at p < 0.05. The results showed statistically significant differences in favor of the caffeine group in the variables of aerobic endurance (F = 5.91; p = 0.020) and explosive power (F = 4.44; p = 0.041), while the other variables showed a trend of improvement without reaching statistical significance. Physiological parameters remained within the limits of physiological acceptability. Conclusion: Acute administration of caffeine has a selective ergogenic effect in a recreationally active population, especially in the domains of endurance and explosive power, without negative cardiovascular consequences.
