Cardiorespiratory Fitness Is Associated with Better Executive Function in Young Women

Purpose: A positive association between cardiorespiratory fitness (CRF) and cognitive function has been demonstrated mainly in children and older adults. Women attending college live in a cognitively demanding setting where optimal cognition matters but often experience declines in CRF. Our aim was to test whether CRF is associated with executive function in young adult women. Methods: Participants in this cross-sectional study included 120 healthy women age 18–35 yr in a university setting. Each woman completed a maximal treadmill-based exercise test to determine peak oxygen uptake (V˙O2peak), computerized tests of executive function, and questionnaires to assess motivation and other factors with potential to influence physical and cognitive performance. Results: Overall CRF was excellent, with a sample mean V˙O2peak of 44.6 mL·min−1·kg−1. After adjusting for covariates, higher V˙O2peak was associated with better performance on attention (P
