response of young people to these nutritional and physiological stressors has not been established. Thus, the purpose of the present study
was to investigate if a bout of moderate-intensity exercise influenced endothelial function (as indicated by flow-mediated dilation (FMD))
following the ingestion of a high-fat breakfast and lunch in adolescent boys (aged 12·6–14·3 years). Two, 2 d main trials (control and exercise)
were completed by thirteen adolescent boys in a counter-balanced, cross-over design. Participants were inactive on day 1 of the control
trial, but completed 60 min of walking at 60% peak oxygen uptake in the exercise trial. On day 2, endothelial function was assessed via
FMD prior to, and following, ingestion of a high-fat breakfast and lunch. There was no difference in fasting FMD between the control and
exercise trial (P¼0·449). In the control trial, FMD was reduced by 32% following consumption of the high-fat breakfast and by 24% following
lunch. In the exercise trial, the corresponding reductions were 6 and 10 %, respectively (main effect trial, P¼0·002). These results
demonstrate that moderate-intensity exercise can attenuate the decline in FMD seen following the consumption of high-fat meals in
adolescent boys.
