Abstract: Purpose: The purpose of this study was to investigate the effects of keto-adaptation via a KD and a strength-power resistance training program on cognitive performance in healthy adults in both a rested and physically stressed state.Methods: Twenty-nine subjects (25 males, 4 females) were placed in either a ketogenic diet (KD) group (N=15) or a high carbohydrate (CON) group (N=14).Resting cognition was measured using the Automated Neuropsychological Assessment Metrics (ANAM) computer battery and physically stressed cognition was measured using a symbol digit modality test (SDMT) before and after high-intensity sprints on a self-propelled treadmill (HiTrainer).These measures were assessed at baseline, and following a 9-12 week dietary and strength/power intervention.Results: No significant difference between groups for diet was observed for resting or physically stressed cognition.For resting cognition within the KD group there existed a significant correlation between acute ketone levels prior to testing and percent change from pre to post for the tests Code-substitution delay and Go/No-go, which test aspects of delayed memory and inhibition.The strength/power intervention produced significant increases for some of the variables in both resting and physically stressed cognition.For resting cognition the tests code substitution -delayed and procedural reaction time, which are associated with learning, delayed memory, and processing speed, improved significantly from pre to post.For physically stressed cognition, the amount of correct answers on the 3 rd set of SDMT following the final sets of sprints improved significantly from pre to post.iii Conclusion: Exercise focused on strength and power seems to beneficially effect cognition at rest and when physically stressed.KD did not improve cognition, but some aspects seemed to be directly affected by acute ketone levels.Further research into both areas and their effects on cognition are needed.
