This study was a descriptive cross-sectional study that assessed the perceptions, knowledge, and use of caffeine by Grand Valley State University athletes that are involved in Track/Field and Swimming/Diving. Questionnaires were distributed and self-administered to 117 athletes (64 in Track/Field and 53 in Swim/Dive between the ages of 18 and 23). Of the swimmers and divers, 54.72% answered that they use caffeine, and only 32.81% of the track and field participants use caffeine according to their responses. A large proportion (80%) of these Grand Valley athletes, perceive that caffeine has a positive effect on speed in short term and concentration or alertness. On the other hand, 75% of the athletes perceive that caffeine has a negative impact on calming nerves. For the most part, the majority of respondents were correct in their responses to amount of caffeine in products. Caffeine content was overestimated in Coke/Pepsi and herbal tea. The most common products used before or during competition included Gatorade, sports waters, Power Bars, multivitamins, instant coffee, orange juice, and Rage.
