Effects of Caffeine on Anaerobic Activity in Trained and Untrained Individuals
Dr. Kevin Cole
It is well documented that caffeine has positive effects when it is coupled with aerobic or long distance exercise. However, the literature shows mixed results when the supplement is taken before anaerobic or short distance events. Certain studies have shown that when caffeine is paired with trained athletes completing sprints, the caffeine has resulted in positive effects. Previous research examining intermediate sprints lasting more than 30 seconds using trained athletes, demonstrates an increase in power output levels. The current study was designed to determine if caffeine had a positive effect on power during a Wingate test. It was also designed to determine whether there was a difference between trained and untrained subjects. Nineteen Hope College males were selected to participate in this study and were split into 2 groups based on power training, trained (n=11) and untrained (n=8). All participants were asked to perform three Wingate tests separated by at least five days. The first test was a familiarization trial where the participants had height and weight recorded and completed a practice Wingate test. The next two trials were preceded by either a caffeine pill or placebo 30 minutes prior to testing administered in a double-blind manner. All participants completed a 5-minute warm-up and a cycle ergometer before the test and a 5-minute cool down afterwards. The data will be thoroughly examined and run through a series of statistical analyses to determine significant differences between treatments and groups.
