Hypertensive patients are at high risk for the development of cardiovascular diseases. The aim of this study was to comparing the fibrinogen, prothrombin time, Partial thromboplastin time and Platelets number and d-dimerin aerobic, control and resistance groups.This study subjects included 36 apparently healthy elderly men. The protocol used in this study was reviewed and approved by Sari University’s Institutional Review Board prior to participant recruitment and all participants provided written informed consent prior to beginning the study.Blood samples were drawn after fasting overnight, after a resting period of 20 min. Fibrinogen was determined by the clotting assay of Clauss. The von Willebrand factor was quantities with an ELISA test kit of Boehringer Mannheim Corp. there are significant differences on fibrinogen, prothrombin time, Partial thromboplastin time and Platelets number and ddimer between aerobic, control and resistance groups.We were therefore interested in possible interactions between themore resistant vessel wall and platelets and coagulation/fibrinolysis factors circulating in the blood.
