“…In previous studies in adolescents, moderate-intensity exercise has been reported to reduce the total area under the plasma triacylglycerol concentrations versus time curve by 8 to 22% (Barrett et al, 2007;Lee et al, 2013;MacEneaney et al, 2009;Sedgwick et al, 2013;Tolfrey et al, 2008;Tolfrey et al, 2012) and high-intensity exercise (10 x 1 min run at 100% peak oxygen uptake) by 11% (Thackray, Barrett, & Tolfrey, 2013). In the present study the corresponding reduction was 13%, demonstrating that repeated bouts of very short (6 s) maximal sprints are effective at reducing postprandial triacylglycerol concentrations.…”

This study investigated if repeated, very short duration sprints influenced endothelial function (indicated by flow-mediated dilation) and triacylglycerol concentrations following the ingestion of high-fat meals in adolescent boys. Nine adolescent boys completed two, 2-day main trials (control and exercise), in a counter-balanced, crossover design. Participants were inactive on day 1 of the control trial but completed 40 x 6 s maximal cycle sprints on day 1 of the exercise trial. On day 2 capillary blood samples were collected and flow-mediated dilation measured prior to, and following, ingestion of a high-fat breakfast and lunch. Fasting flow-mediated dilation and plasma triacylglycerol concentration were similar in the control and exercise trial (P>0.05). In the control trial flow-mediated dilation was reduced by 20% and 27% following the high-fat breakfast and lunch; following exercise these reductions were negated (main effect trial, P<0.05; interaction effect trial x time, P<0.05). The total area under the plasma triacylglycerol concentration versus time curve was 13% lower on day 2 in the exercise trial, compared to the control trial (8.65 (0.97)

“…This effect has been show through both cycling and treadmill running [108, 109]. Additionally, the benefits of high-intensity exercise have also been shown in youth populations, where higher exercise intensities are more likely to be achieved than in adult populations [110, 111]. A recent quantitative review by Freese et al 2014, compared high-intensity exercise to low-to-moderate intensity aerobic exercise.…”

“…For example, moderate-intensity exercise appears to both lower PPL [127] and improve endothelial function [128] the morning after exercise. Notably, the positive effects of intermittent exercise and high-intensity interval training, may be especially advantageous in youth, due to the often spontaneous nature of youth exercise and an increased ability to handle high-intensity exercise bouts as compared to adult populations [110, 129, 130]. Youth populations should be encouraged to meet physical activity guidelines and engage in high-intensity exercise when possible.…”

Postprandial lipemic and inflammatory responses to high-fat meals: a review of the roles of acute and chronic exercise

et al. 2016

Postprandial lipemia is an independent risk factor for development of cardiovascular disease. Postprandial inflammation following the prolonged elevation of triglycerides occurring subsequent to ingestion of high-fat meals, provides a likely explanation for increased disease risk. Substantial evidence has shown that acute exercise is an effective modality for attenuation of postprandial lipemia following a high-fat meal. However, much of the evidence pertaining to exercise intensity, duration, and overall energy expenditure for reducing postprandial lipemia is inconsistent. The effects of these different exercise variables on postprandial inflammation is largely unknown. Long-term, frequent exercise, however, appears to effectively reduce systemic inflammation, especially in at-risk or diseased individuals. With regard to an acute postprandial response, without a recent bout of exercise, high levels of chronic exercise do not appear to reduce postprandial lipemia. This review summarizes the current literature on postprandial and inflammatory responses to high-fat meals, and the roles that both acute and chronic exercise play. This review may be valuable for health professionals who wish to provide evidence-based, pragmatic advice for reducing postprandial lipemia and cardiovascular disease risk for their patients. A brief review of proposed mechanisms explaining how high-fat meals may result in pro-inflammatory and pro-atherosclerotic environments is also included.

“…Nine studies have investigated the effect of acute exercise on postprandial lipemia in young people using the criteria adopted for this summary (3,41,42,69,70,76,78,80,81). A summary of these studies is presented in Thus, an exercise-induced deficit is efficacious, but a closer examination of the exercise characteristics might be more enlightening and will be used to compare and contrast the main outcomes with the adult-based literature appraised above.…”
