Abstract

BACKGROUND: Acute exercise is a behavior that benefits cognitive function; however, its effect on populations with different risks for Alzheimer's disease (AD) and the role of exercise variance and Apolipoprotein E (APOE) genotype on this effect remains unknown. This study explores the acute exercise effect on behavioral and neurocognitive function, and its potential moderation by exercise intensity and duration and APOE genetic risk. METHODS: Fifty-one cognitively normal adults (~36% APOE ε4 carriers) performed the Stroop task under a rest condition and 3 exercise conditions while electroencephalographic activity was assessed. RESULTS: Acute exercise improved cognitive performance assessed through both behavioral and neuroelectrical indices. These benefits were observed regardless of adjustments of intensity and duration at a predetermined exercise volume as well as being evident irrespective of APOE ɛ4 carrier status. CONCLUSIONS: Acute exercise could be proposed as a lifestyle intervention to benefit neurocognitive function in populations with and without genetic risk of AD. Future exploration should further the precise exercise prescription and also the mechanisms underlying the beneficial effects of acute exercise for neurocognitive function.
