The effect of an exhausting bout of aerobic exercise and consumption of cocoa on blood fibrinogen of elite male Karateka

چکیده مقاله

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<0.01). Therefore, the cocoa on blood fibrinogen of elite male
athletes immediately and one hour after an exhausting session of
aerobic exercise have no effect.
Conclusion: Cocoa, alone or combined with aerobic exercise
exhausting had no effect on blood fibrinogen index of men elite
karateka.
