Abstract

Introduction & Objective: Atherosclerosis is one of the leading causes of cardiovascular disease  and research has shown that regular physical exercise with appropriate intensity and duration It can improve cardiovascular function, especially in patients with atherosclerosis, but little research has been done on the effect of different exercises (aerobic, resistance and strength) on arterial biomechanics (peripheral and central) and there are contradictory results. In addition, few studies have been done on middle-aged people. The main purpose of this study was to evaluate the effect of eight weeks of aerobic training on selected variables bilateral femoral artery biomechanics in middle-aged men, three to seven days after coronary angioplasty. Methodology: Thirty patients with coronary angioplasty who underwent coronary angioplasty, ranging in age from 45 to 60 years, were randomly selected from the patients referred to the Rehabilitation Clinic of Tehran Cardiac Center. Arterial resting lumen diameter(LD) in systolic and diastolic phases and intima-medial thickness(IMT) of bilateral femoral artery, compliance and ratio of intima-media thickness to lumen diameter(IMT/LD) were measured before and after exercise. The aerobic exercise program was performed for eight weeks and three sessions per week, each session lasting 40 minutes on three devices: treadmills, an arm ergometer and a workhorse, for each patient. In this study, analysis of covariance tests at the significance level of 0.05, paired t-test and Will Coxon test were used. Results: The results showed that aerobic exercise on selected variables of vascular biomechanics [resting lumen diameter in systolic and diastolic phase] , Was confirmed at the significance level of 0.05 and Although the effect of aerobic exercise was not significant in some variables of vascular biomechanics [compliance and ratio of intima-media thickness to lumen diameter] . in some angioplasty patients; But in general, all variables have improved in order to improve and reach the norm of normal people. Conclusion: The present study concluded that aerobic exercise improves the biomechanical condition of the arteries and suggests that performing consistent exercises having is of paramount importance in heart patients to prevent further heart attacksheart patients.
