Abstract: The aim of this study was to determine how measures of ejection duration, subendocardial viability ratio, and central arterial health are affected by the overweight condition in a sample of adolescent children. 34 sex and age-matched adolescent children were studied, with half of the total sample (17, 11 male, 6 female) overweight. In one laboratory visit, anthropometric measures, body composition analysis, and non-invasive measures of central cardiovascular health, including heart rate (HR), aortic systolic blood pressure (ASBP), carotid- femoral pulse wave velocity (cf-PWV), ejection duration in milliseconds (EDms) and relative (ED%), and the subendocardial viability ratio (SEVR) were performed. cf-PWV and ASBP were significantly greater, and SEVR lower in overweight compared to normal weight participants. Measures of ED% and HR were not significantly different between groups despite a positive trend in mean values with overweight status and moderate effect sizes for both. Overweight adolescents report unfavorable cardiovascular changes as measured by cf-PWV, ASBP, and SEVR. Although significance was not observed, our findings indicate that the ED% may still lend to the assessment of CVD risk in a larger sample including more obese adolescents.
