Background: No doubt that exercise plays an integral role in the protection against cardiovascular disorders, however decision for the proper exercise intensity may constitute the major challenging step in achieving that goal. Objective; to compare between the effect of different treadmill exercise intensities on selected cardiovascular parameters including; blood pressure , maximum and resting heart rate in addition to coagulation factors including; bleeding time, clotting time, prothrombin time, prothrombin concentration, and platelets count Subjects & Methods: Forty-five sedentary mild hypertensive women were recruited for the study their ages ranged from 30 to40 years old, subjects were divided into three study groups according to their exercise intensities: Group A (50%-65% of THR), B (65%-75% of THR) , and C (75% to 80% of THR) , they all participated in an exercise training program on treadmill for twenty minute three times per week for 12 successive weeks. Results: significant decrease in bleeding time, clotting time, in group (C) with significant increase in platelets count in the same group compared to group (A)&(B). For selected cardiovascular parameters, result showed significant reduction of systolic and diastolic blood pressure in both groups (A&B) compared to group (C) Conclusion: The walking exercises of low and moderate intensities have a positive effect on blood pressure with minimal impact in coagulation profile in mild hypertensive female.
