Targeted Assessment of Cognition and Tactical-performance With Ingested Ketones

In this study, 20 active SWAT team members will be randomized into two groups: ExogenousKetone Supplement (EKS) and Placebo (PLA).Participants will complete the trial in a crossover manner (meaning each participant willcomplete both EKS and PLA conditions)Our primary outcome of interest is changes in cognitive performance following anexhaustive exercise bout. Secondary outcomes include: changes in marksmanship accuracyand speed, and changes in select biomarkers (catecholamines, cortisol, and BDNF).Although ketone supplements are marketed for energy and cognitive performance, little isknown about how they affect biological markers during stressful environments. Findingsfrom this study may help inform safe, evidence‐based use of such supplements amongtactical athletes.
