Isometric exercise and cognitive function: an investigation of acute dose–response effects during submaximal fatiguing contractions

The purpose of this study was to explore the dose-response relationship between exercise and cognitive performance using an acute bout of isometric exercise. University students (N = 55) were randomly assigned to control, 30%, 50% and 70% of maximum voluntary handgrip contraction groups. Participants performed a modified Stroop task before and after completion of an isometric handgrip endurance trial at their assigned exercise intensity. …
