Effect of exercise intensity on postprandial lipemia, markers of oxidative stress and endothelial function after a high-fat meal

Purpose: The aim of this study was to compare the effect of two different exercise intensities on postprandial lipemia, oxidative stress markers and endothelial function after a high-fat meal (HFM). Material and methods: Eleven young men completed 2-day trials in three conditions: Rest, moderate-intensity exercise (MI-Exercise) and heavy-intensity exercise (HI-Exercise). Subjects performed an exercise bout or no exercise (Rest) on the evening of day 1. On the morning of day 2, a HFM was provided. Blood was sampled at fasting (0 h) and every hour from 1 to 5 h during the postprandial period for triacylglycerol (TAG), thiobarbituric acid reactive substance (TBARS) and nitrite/nitrate (NOx) concentrations. Flow-mediated dilatation (FMD) was also analyzed. Results: TAG concentrations were reduced in exercise conditions compared to Rest during the postprandial period (PThe accepted manuscript in pdf format is listed with the files at the bottom of this page.
