There is evidence that intense physical activity has a potential effect on thrombotic events due to catecholamine release. The hormones leptin and adiponectin have been used as markers of cardiovascular risk, but they are few and contradictory studies that relate physical training intensity and duration of high plasma concentrations of these hormones. The use of antioxidants, such as proanthocyanidins present in grapes, may help in reducing the undesirable effects of intense training.
Fifty four Brazilian healthy military without hyperglycemia, diabetes mellitus and endocrine disease were enrolled in this study. All subjects were high physically military trained. The Ethical Committee of the Universidade do Estado do Rio de Janeiro in Brazil (COEP008/2011) approved the study protocol. Informed consent was obtained from each subject after explanation of purpose and risks of all procedures used.
