A single ~60-minute session of moderate-intensity exercise performed 12-18 hours before a standardized meal reduces postprandial triacylglycerol concentrations in children and adolescents.
Does acute exercise reduce postprandial triacylglycerol concentrations in young people?
Acute exercise, including moderate-intensity sessions and intermittent activities, effectively reduces postprandial triacylglycerol concentrations in children and adolescents, potentially improving early cardiovascular risk profiles.
Exaggerated postprandial triacylglycerol concentrations (TAG) independently predict future cardiovascular events. Acute exercise and diet interventions attenuate postprandial TAG in adults. This paper aims to examine the exercise postprandial lipemia studies published to date in young people. Nine studies satisfied the inclusion criteria adopted for this summary. The majority of studies are in boys (22% girls) and have shown a single ~60-min session of moderate-intensity exercise, performed 12-18 hours before a standardized meal, reduces postprandial TAG. Manipulations of exercise duration and intensity suggest an exercise energy expenditure dose-dependent response is not supported directly in healthy young people. Studies investigating alternative exercise bouts have reported lower postprandial TAG after simulated intermittent games activity, high-intensity interval running and cumulative 10-min blocks over several hours, which may appeal to the spontaneous physical activity habits of young people. Although extension of these initial findings is warranted, exercise may be an effective strategy to promote regular benefits in TAG metabolism in children and adolescents; this may contribute to an improved cardiovascular disease risk profile early in life.
Tolfrey et al. (Thu,) conducted a review in Postprandial lipemia. Acute exercise was evaluated on Postprandial triacylglycerol concentrations (TAG). A single ~60-minute session of moderate-intensity exercise performed 12-18 hours before a standardized meal reduces postprandial triacylglycerol concentrations in children and adolescents.
