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

    Purpose: To compare the strength of associations between different indicesof cardiorespiratory fitness (CRF) and brain health outcomes in children withoverweight/obesity.Methods: Participants were 100 children aged 8–11 years. CRF was assessedusing treadmill exercise test (peak oxygen uptake [V̇O 2peak], treadmill time, andV̇O 2 at ventilatory threshold) and 20-metre shuttle run test (20mSRT, laps, run-ning speed, estimated V̇O 2peak using the equations by Léger et al., Mahar et al.,and Matsuzaka et al.). Intelligence, executive functions, and academic perfor-mance were assessed using validated methods. Total gray matter and hippocam-pal volumes were assessed using structural MRI.Results: V̇O 2peak/body mass (β = 0.18, 95% CI = 0.01–0.35) and treadmill time(β = 0.18–0.21, 95% CI = 0.01–0.39) were positively associated with gray mat-ter volume. 20mSRT laps were positively associated with executive functions (β = 0.255, 95% CI = 0.089–0.421) and academic performance (β = 0.199–0.255, 95%CI = 0.006–0.421), and the running speed was positively associated with executivefunctions (β = 0.203, 95% CI = 0.039–0.367). Estimated V̇O2peak/Léger et al. was posi-tively associated with intelligence, executive functions, academic performance,and gray matter volume (β = 0.205–0.282, 95% CI = 0.013–0.500). EstimatedV̇O 2peak/Mahar et al. and V̇O 2peak/Matsuzaka et al. (speed) were positively associated withexecutive functions (β = 0.204–0.256, 95% CI = 0.031–0.436).Conclusion: Although V̇O2peak is considered the gold standard indicator ofCRF in children, peak performance (laps or running speed) and estimatedV̇O 2peak/Léger et al. derived from 20mSRT had stronger and more consistent asso-ciations with brain health outcomes than other indices of CRF in children withoverweight/obesity
