Abstract

Introduction: Caffeine intake has become an important and popular ergogenic aid among diverse populations aimed at optimizing physical training. Objective: To investigate the acute effect of caffeine on performance of maximum strength in women. Methods: 20 women with a mean age of 20.3 ± 1.7 years, with no previous experience in weight training. Divided into two groups (G1 = caffeine, and G2 = placebo). It was assessed muscle strength through the test of a maximum repetition. Results: After the caffeine intake was increased absolute load for the bench press exercise (without caffeine = 37.8 + 5.28 = 39.2 + caffeine 6:05; p = 0.45), not observable increase in performance for the leg press 45º and the placebo group. Conclusion: caffeine as an ergogenic aid has increased the performance in strength maximum test for the bench press, but did not alter the force production in the leg press 45º exercise.
