Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
A double-blind, randomized crossover design will be employed. Three types of supplements will be tested: placebo, caffeine (220 mg), and an energy drink containing 220 mg caffeine, 288 mg anserine, 400 mg elderberry, and 660 mg of a vitamin-mineral mixture. Twelve college athletes will be recruited to complete repeated sprint tests on a cycle ergometer until exhaustion and to undertake a series of cognitive tasks during exercise.
