Abstract
The aim of this study was to investigate the impact of caffeine on high intensity exercise. Trained male university students (n=12, 20.5±0.67 years, 83.8±6.57kg) volunteered to participate in the study. The testing protocol was a randomised, counter balanced, double-blinded design and was completed over a two-week period during two sessions, with participants consuming a caffeinated gel and a placebo gel. The gel contained 75mg of caffeine and was consumed one-hour before exercise. Five exercises were used for testing; one repetition maximum squat, one repetition maximum bench press (with 3-4 minutes rest between attempts) three loaded jump squats at 40% of 1RM, three medicine ball pushes with 5kg medicine ball, and a 10 second sprint of a Wingate. The caffeine gel increased performance in all five of the exercise with a percentage increase when caffeine was consumed compared to the placebo trial. A significant difference was noted in the squat, loaded jump squat and medicine ball push (Caffeine = 143.1 ± 23.1 VS. Placebo = 138.3 ± 22.1 P<0.05; Caffeine = 1160.5 ± 206.13 VS. Placebo = 1093.2 ± 212.63 P<0.05 and Caffeine = 6.2 ± 0.42 VS. Placebo = 5.9 ± 0.41 CM respectively). Overall performance was improved when caffeine was consumed one-hour prior to exercise. However, there were no significant difference noted in the bench press and Wingate.
