Background:There is a great deal of variability in the cortisol level with regard to type, intensity, volume and frequency of exercise. Purpose:to determine the difference between aerobic and resistive exercises on cortisol level in hypertensive patients.Methods: Forty mild essential hypertensive patients from nonsmoker men with age range from 40-50years, with SBP ranges from (140-159) mm Hg and DBP from (90-99) mm Hg, participated in this study .They were chosen from External clinic of faculty of physical therapy, Cairo University .All patients were assigned randomly into two groups, equal in number. Their cortisol level was measured before , after two hours from 1st session and after 8 weeks of training program for both groups. Group A :20patients performed aerobic exercises in form ofTreadmill walking exercisefor 40 minutes atIntensity detected according to ''karvonen equation'' Group B :20 patients performed resistive exercises at intensity : 40 %to 60% of 1-RM..Patients performed 3 sessions per week for 8 weeks.Results:Serum cortisollevel before training in comparison to post1 (after 1st session) show no significant difference in both groups. Serum Cortisol levelafter training (post2-after 8 weeks) in comparison to before training was significantly decreased in Group A and in Group B , this decrease in favor of group A so there was significant difference in post training serum cortisol level between two groups.Conclusion: Aerobic exercise can lower serum cortisol level more than resistive exercise in hypertensive patients after 8 weeks of training and both of them has no effect on acute response of cortisol in hypertensive patients
