The aim of this randomized, double-blind, placebo-controlled, cross sectional study was to determine the acute effects of caffeine on the velocity of the concentric part of movement when performing bench press exercise in individuals experienced in resistance training. The sample consisted of 25 subjects (age (mean ± standard deviation) 23.0 ± 2.0 years, height 182.9 ± 7.3 cm, weight 83.2 ± 11.3 kg) who performed three visits to the laboratory. The first visit was a familiarization visit, subsequently followed by two visits in which movement velocity was assessed after consumption of 6 mg/kg of caffeine or 6 mg/kg of placebo. The task for the subjects was to perform one repetition with the maximum velocity of the concentric part of the movement at 50%, 75% and 90% of their one maximum repetition (1RM). A statistically significant difference was obtained at loads of 75% 1RM (p <0.001; + 6.7%) and 90% 1RM (p <0.001; + 9.1%) in favor of caffeine condition compared to placebo, while at a load of 50% 1RM (p = 0.48; + 1.0%) there was no statistically significant difference in performance. It was concluded that caffeine has an ergogenic effect on the movement velocity during bench press exercise, and its effect are more pronounced at higher loads (i.e., when the requirements for generating muscle force are higher). Based on the results of the research, it may be recommended to consume caffeine before resistance training (at least when upper-body exercises are involved) for the purpose of acute performance improvements.
