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

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: () REST: rest for 45 min; () MIE: moderate-intensity exercise; and () HIE: heavy-intensity exercise. Experimental conditions were performed in the evening. On the following morning, blood samples were taken in the fasted state (0 h) and at 1, 3, and 5 h 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 1 h ( < 0.033) and IL-10 incremental area under the curve (iAUC) was greater in the MIE ( = 0.027) and HIE ( = 0.045) trials vs. REST. Lower levels of anti-coagulation factor VII (FVII) were observed at 1 h in the MIE condition vs. REST ( = 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. 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.
