Abstract
Introduction: Current evidence shows sedentary screen based media contributes to the increase in physical inactivity and obesity. New-generation active computer console games ("exergames") offer an alternative to traditional sedentary gaming activities. Studies have suggested that exergaming requires enough energy expenditure to contribute towards health gains, although it is unclear whether exergaming produces a cardiovascular response that would stimulate improvements similar to regular physical activity. The purpose of this study was to compare different intensities of exergaming on both energy expenditure and vascular function, measured non-invasively using the brachial artery flow-mediated dilation (FMD) technique. We hypothesised a high intensity exergaming condition would demonstrate a larger change in heart rate (HR), energy expenditure (EE) and vascular health (FMD) compared to a low intensity exergaming condition. Methods: Fifteen children (10 ± 1 yr., BMI 18.1 ± 2.3kg/m2; 7 girls, 8 boys) participated in a within subjects cross over design study. Participants took part in three separate sessions in a counterbalanced order consisting of a graded exercise test (GXT) and two gaming sessions. High exergaming (HE; Kinect Sports - Hurdles) and low exergaming (LE; Kinect Sports - Ten Pin bowling) sessions were played for 15 minutes, as per manufacturer specifications. Flow-mediated dilation (FMD) was measured pre and post exergaming to assess the effects on vascular health.
