The purpose of this study was to investigate the effects of 100mg of caffeine (capsule form) on the performance of eight male runners, whilst performing an 800m trial on a motorised treadmill (model- h/p/cosmos Quasar). In the testing protocol vitamin C tablets were used as the placebo and a blinded experimental design was used throughout the investigation. For both trials, treatments were given one hour prior to testing and subjects were asked to refrain from the consumption of caffeinated foods or beverages for 48hr prior to the time trials. The aim of the study was to determine whether significant differences existed in running time, rate of perceived exertion, heart rate, blood lactate concentrations and respiratory parameters between the placebo and caffeine trials in order to understand the ergogenic effect of caffeine on performance of this nature. The results clearly demonstrated that there was no significant difference for any of the measured variables (p>0.05) suggesting that caffeine had no ergogenic effect on this aspect of exercise. The study concluded that under laboratory conditions, the ingesting of 100mg of caffeine did not enhance performance of short term high intensity exercise, although dosage used in the study was relatively low hence the IOC could be justified in placing caffeine on the monitoring programme as higher doses of caffeine may have quite a different effect.
