The effect of endurance training on platelet function in men

Abstract

10 healthy, sedentary males were performed 30 minutes of cycling with a load corresponding to 75 % of max¬imal heart rate, 3 times a week, during 6 weeks. ADP and collagen-induced platelet aggregation, ATP release and platelet count were estimated before and after the first exercise and, the exercises that performed at the 3rd and 6th weeks of the training. , The ADP and collagen-induced platelet aggregation increased significantly after the first exercise. The aggrega¬tion responses to ADP and collagen did not alter in relation with the exercise at the 3rd and 6th weeks. No alteration was found in ATP release of platelets and platelet count during training. The platelet aggregation increased at rest by the training program. Our findings indicate that regular physica-l exercise results in an adaptation of platelet function.
