Abstract

Background: We tested the hypothesis that an active video game following a high-fat meal would partially prevent the unfavorable effect of a high-fat meal on vascular function in overweight adolescents. Methods: Twenty-four overweight adolescents were randomized to either a 60-minute active video game (AVG) group (n = 12) or seated rest (SR) as a control group (n = 12) after a high-fat meal. Blood parameters were measured, and vascular function was measured using brachial artery flow-mediated dilation (FMD) at baseline and 3 hours after a highfat meal. Results: No significant interaction was found in any blood parameter. A high-fat meal significantly increased blood triglyceride and glucose concentrations in both groups in a similar manner. Brachial artery FMD significantly decreased in the SR group (13.8 ± 3.2% to 11.8 ± 2.5), but increased in the AVG group (11.4 ± 4.0% to 13.3 ± 3.5), with a significant interaction (P =.034). Conclusion: These findings show that an active video game attenuated high-fat meal-induced endothelial dysfunction. This suggests that an active video game may have a cardioprotective effect on endothelial function in overweight adolescents when exposed to a high-fat meal.
