Hwang J, et al. - An inquiry was performed of the tie-up between aerobic fitness and cerebrovascular function with neurocognitive functions among healthy, young adults. Measures of VO₂max, cerebral vasomotor reactivity (CVMR), and fluid reasoning exhibited a positive inter-connection via statistical modeling. Nevertheless, the association between VO₂max and fluid reasoning was not reliably mediated by CVMR. Data disclosed that a high capacity for maximal oxygen uptake among healthy, young adults correlated with greater CVMR and better fluid reasoning, which indicated that high-aerobic fitness possibly promoted cerebrovascular and cognitive functioning abilities.
