Abstract :
Cardiovascular disease is regarded as the main indicator of cardiac arrests and the leading cause of mortality. Platelets, as the blood factors, play an important role in the etiology of cardiovascular diseases and its associated risk factors. According to the increased risk of abnormal clot formation in main artery by intense exercises and the Platelets role in the promotion of cardiovascular diseases, strategies including cocoa (flavanol-rich foods) consumption has become more widespread. In this semi- experimental study, 20 healthy male soccer players with a mean (22±1years, Vo2max=53.70±1.5) participated randomly in an exhaustive exercise (Bruce) in two consecutive weeks. After the first stage of blood sampling, each athlete consumed around 5 mg kg of the bottles containing placebo or cocoa and two hours following that performed Bruce test. Before, immediately and one hour after the test, blood sampling stages II, III and IV were taken. Data were analyzed by a two- factor analysis of variance (ANOVA) with repeated measures at p < 0.01. The results have shown that cocoa consumption solely or in combination with exercise influenced on Plt, MPV and PDW markers and resulted into the decrease of them (P < 0.01). And also there was a significant difference between the values of research parameters in stages two and three. These findings indicate that one session of exhaustive aerobic exercise may have an influential effect on blood Plt, MPV, and PDW levels of male soccer players.
