摘要

Highly trained competitive swimmers (n=11) aged 18-21 participated in randomised experimental protocol including a washout period with no chocolate intake and a supplementation period with daily ingestion of 50 grams dark chocolate, of 10 days length each. Two submaximal tests on bicycle ergometer of 15 min each (10 min at 60% VO_2 max and 5 min at 90% VO_2max) were conducted to induce oxidative stress. Significant increase was found after the pre-supplementation submaximal test carried out at the end of washout period in leukocytes and lymphocytes by 24.6%, monocytes by 16.7%, neutrophils by 27.5% and platelets by 15.8%. C-reactive protein was elevated 2.3 times up to 3.44 mg/L. The submaximal testing performed after the chocolate supplementation period did not precipitate an increased response in these biomarkers No changes were recorded in the IgA and IgM. In conclusion, short-term dark chocolate supplementation may have an attenuating effect on the immune system by favourably improving C-reactive protein, leucocytes, neutrophils and platelets responses to oxidative stress induced by submaximal exercise.
