Glycemic patterns may provide a mechanism between CRF and health.<h4>Objectives</h4>This study assessed the feasibility of measuring glycemic patterns using continuous glucose monitoring (CGM) in adolescents, aged 14-22 y, to estimate the relationship between VO₂ max and glucose patterns.<h4>Methods</h4>Healthy adolescents (<i>n</i> = 30) were recruited for a treadmill VO₂ max test and to complete the following activities for 7-10 d: <i>1</i>) wear a Dexcom G6 CGM, <i>2</i>) complete ≥3 24-h dietary recalls, and <i>3</i>) complete 1 at-home oralCurrent developments in nutrition104547https://www.ebi.ac.uk/biostudies/studies/S-EPMC11847740biostudies-literatureImpact of Dietary Intake and Cardiorespiratory Fitness on Glycemic Variability in Adolescents: An Observational Study.PMC11847740Harrison CMeijer JLLebby SRChowkwale SGe MVajravelu MEPalmer GMGilbert-Diamond DLoud KJfalseImpact of Dietary Intake and Cardiorespiratory Fitness on Glycemic Variability in Adolescents: An Observational Study.<h4>Background</h4>Cardiorespiratory fitness (CRF), estimated by maximum oxygen consumption (VO₂ max) during exercise, is worsening among adolescents and associated with a decline in metabolic health into adulthood.
