Acute Strength Exercise Decreases Satiety by Modifying Blood Cytokines Levels in Physically Active Men

Abstract Aim: Exercise elicits adaptations in several physiological systems, such as the gastrointestinal tract. We evaluated the effects of an acute strength exercise (acute-SE) on gastric satiety and its correlation with creatinine kinase (CK), lactate, and plasma cytokine levels in humans. Method...

Description
Summary:	Abstract Aim: Exercise elicits adaptations in several physiological systems, such as the gastrointestinal tract. We evaluated the effects of an acute strength exercise (acute-SE) on gastric satiety and its correlation with creatinine kinase (CK), lactate, and plasma cytokine levels in humans. Methods: Anthropometric parameters, body composition, muscular strength, and satiety (drink test protocol) at rest and exercise were assessed. Results: In the squat, bench press, and T-bar row exercises, we observed a significant decrease (p<0.05) in muscular strength in the second, third, and fourth sets compared with that in the first set. Compared with rest, we observed a significant increase (p<0.05) in CK and lactate levels after acute-SE. In the drink test, acute-SE significantly increased (p <0.05) the total intake, calories ingested, and a total time of ingestion. Concerning cytokines, there was a significant increase (p<0.05) after acute-SE of IL-1β and IL-6 levels at the beginning of the test and a decrease in IL-6, -10, -13, and TNF-α levels after acute-SE at the end of the test (p<0.05). There was a correlation between CK, lactate, and total intake after acute-SE (p<0.05) as well as between IL-6, 13, TNF-α, and volume ingested in the last score of the drink test after acute-SE (p<0.05). Conclusion: Acute-SE decreases satiety associated with changes in lactate, CK, and plasma cytokine levels in healthy humans.
