Multiple linear regression models of cerebral pulsatility index as the dependent variable with age and V̇o_2max as the independent variables in all participants (n = 153), men only (n = 79) and women only (n = 74). Cerebral pulsatility index was measured in the middle cerebral artery. V̇o_2max, maximal oxygen consumption.
