Aerobic exercise improves postprandial inflammatory and hemostatic markers after a high-fat meal: a randomized crossover study.

Abstract

Exercise intensity modulates postprandial lipemia. However, its effect on hemostatic and pro- and anti-inflammatory markers in the postprandial state is still unknown. Eleven young males performed a 2-day trial on different conditions: (i) REST: rest for 45min; (ii) MIE: moderate-intensity exercise; and (iii) HIE: heavy-intensity exercise. Experimental conditions were performed in the evening. On the following morning, blood samples were taken in the fasted state (0h) and at 1, 3, and 5h after the consumption of a high-fat meal (HFM). Interleukin-10 (IL-10) levels were higher in the HIE vs. MIE trial at 0 and 1h (p< 0.033) and IL-10 incremental area under the curve (iAUC) was greater in the MIE (p= 0.027) and HIE (p= 0.045) trials vs. REST. Lower levels of anti-coagulation factor VII (FVII) were observed at 1h in the MIE condition vs. REST (p= 0.043). In comparison with REST, MIE improved hemostatic (FVII) and anti-inflammatory markers (IL-10 iAUC) whereas HIE enhanced IL-10 in the postprandial state. Regardless of the exercise intensity, aerobic exercise mitigates the deleterious consequences of an HFM. Novelty: Prior aerobic exercise at moderate-intensity attenuates next day's postprandial FVII and IL-10 levels whereas exercise performed at heavy-intensity increases IL-10 levels. Moderate-intensity exercise may be more beneficial to improve hemostatic (FVII) and anti-inflammatory (IL-10) responses while heavy-intensity exercise may improve anti-inflammatory (IL-10) levels only.
