Results from two multiple linear regression analyses. Bold indicates P < 0.05. Abbreviations: β: standardised beta coefficient; gCBF: global cerebral blood flow; gATT: global arterial transit time; SBP: systolic blood pressure; DBP: diastolic blood pressure; BMI: body mass index; V̇O2peak: peak oxygen consumption.
