Abstract
Background: Fibrinogen (Fib) as a separate factor and influencing the risk of Cardiovascular is associated with the development of coronary heart disease. On the other hand, intense exercise increases the rate of early heart attacks. Due to the increased risk of abnormal clotting of blood vessels by intense exercise and the role of fibrinogen in cardiovascular diseases, strategies such as cocoa consumption has become more widespread.
Materials and Methods: in a one-group double-blind experimental study, 11 elite male karateka (mean age: 21±2 years; height: 176.96± 3.41 cm) were participated randomly in two consecutive weeks (first week: placebo: six subjects and cocoa: five subjects, second week: placebo: five subjects and cocoa: six subjects) of exhaustive exercise (Bruce). Each athlete, after the first stage of blood sampling, the bottles contained placebo and cocoa into the mg.kg-1 5 will consume and two hours later did the Bruce test. Therefore, each athlete did the test tow order (1- after placebo consumption, 2- after cocoa consumption). Immediately before the test, immediately after and one hour after the test, a blood sample in the second, third and fourth were taken. Differences were examined using a two-factor analysis of variance (ANOVA) with repeated measures as appropriate.
Results: Significant differences in fibrinogen levels during different stages of the cocoa consumption were not observed. These results indicate no effect of cocoa consumption on indicators of fibrinogen (P
