Which indices of cardiorespiratory fitness are more strongly associated with brain health in children with overweight/obesity?

ABSTRACT:

Purpose

To compare the strength of associations between different indices of cardiorespiratory fitness (CRF) and brain health outcomes in children with overweight/obesity.

Methods

Participants were 100 children aged 8-11 years. CRF was assessed using treadmill exercise test (peak oxygen uptake [V̇O_2peak ], treadmill time, and V̇O₂ at ventilatory threshold) and 20-metre shuttle run test (20mSRT, laps, running speed, estimated V̇O_2peak using the equations by Léger et al., Mahar et al., and Matsuzaka et al.). Intelligence, executive functions, and academic performance were assessed using validated methods. Total gray matter and hippocampal volumes were assessed using structural MRI.

Results

V̇O_2peak /body mass (β = 0.18, 95% CI
