Here we use magnetic resonance elastography (MRE) to quantify brain mechanical properties of 30 individuals aged 19-30 immediately before a high intensity interval training (HIIT) exercise, immediately after exercise, and 1 hour after exercise. We additionally tested subjects’ cognitive performance at these time points through a memory task and two executive function tasks. We found that whole brain stiffness decreased in nearly all subjects immediately after exercise by an average of 4.2% (p<0.0001) and that whole brain damping ratio increased by an average of 3.1% (p=0.001). Performance on all three cognitive tasks improved immediately after exercise (p<0.05).
