Cardiorespiratory fitness weakly predicts executive function in older adults

We examined the relationship between cardiorespiratory fitness (VO2Max) and executive function (Tower of London and Mazes composite) in a sample of 50 healthy older adults aged 64-86 (46% female). Higher fitness was associated with better executive function (r = .284, p = .048). However, after controlling for sex, there was no longer a significant association between V02Max and executive function (beta = .179, p = .209). Implications for future research will be discussed.
