Activation of Thrombocytes and the Hemostatic System During Maximal Cycle Exercise in Healthy Triathletes

Physical exercise is widely regarded to be important for health. However, heavy physical exertion has been shown to be associated with a higher incidence of myocardial infarction (3, 13, 30). It has also been shown that physical exercise activates fibrinolysis, coagulation and thrombocytes (8, 9, 10, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 26, 27, 28). Methodological problems, such as in vitro activation of platelets, limited the value of earlier studies. Newly developed analytical tests for molecular markers of the hemostatic system (20) and flow-cytometric techniques for the detection of surface antigens on platelets (25) have enabled more detailed insights into the changes of the hemostatic system during exercise.
