Improving Cognition With Neurodegradation Countermeasure

The goal of this randomized, placebo-controlled, three-condition, double-blind, within-participants crossover clinical trial is to compare caffeine, TeaCrine plus caffeine, and a placebo condition in ROTC or tactical personnel. The main question it aims to answer is the effect of the condition on measures of cognitive performance, cardio-autonomic, and hemodynamic responses after a physically demanding protocol. The physiological function will be derived from metrics of heart rate variability, whilst cogntive performance will be evaluated using tasks that assess cognitive domains of executive function, reaction time, and memory. Participants will report to the lab 4 times, once for familiarization of cognitive measures and then 3 times for their experimental visits. Participants will consume their randomized condition an hour prior to the fatiguing interval exercise protocol. Following they will complete a series of cognitive tasks.
