Caffeinated beverages are incredibly popular for improving mental acuity and exercise performance, and their ergogenic effects have been thoroughly studied. For our research project, we wanted to study the effects of caffeine, specifically caffeinated energy drinks, on muscular endurance. There are hundreds of energy drinks on the market with varying ingredients in addition to caffeine that claim to have substantial physiological benefits, so when choosing energy drinks for the study, we chose Alani Nu and Celsius because of the similarities in marketing strategies, ingredients, and serving size. We asked this questions: is there a significant difference in muscular endurance when an Alani Nu is consumed prior to exercise compared to a Celsius? Our hypothesis was that there would be a significant improvement in muscular endurance when caffeine was consumed via Alani Nu an hour before exercise when compared to consuming Celsius prior an hour before exercise.
