Effects of caffeine supplementation on physical performance and mood dimensions in elite and trained-recreational athletes

Fig. 1 Panel a shows the scores recorded for the dimension tension. Higher tension scores were reported by elite athletes after supplementation with caffeine compared to placebo; Panel b shows the scores recorded for the dimension vigor. Scores for vigor were significantly higher after caffeine supplementation in the elite athletes compared to the trained-recreational athletes. Further, elite athletes returned higher vigor scores after supplementation with caffeine compared to placebo; Panel c shows the scores recorded in the SVS. Elite athletes showed larger SVS values after supplementation with caffeine versus placebo. a: significant differences were detected in elite athletes when caffeine was compared with placebo. b: significant differences after caffeine supplementation were detected in elite athletes versus trained-recreational athletes
