Abstract
Introduction & Objective
A sedentary lifestyle leads to cardiovascular disease including atherosclerosis. Despite the application of therapeutic interventions such as angioplasty on these patients recurrence of stenosis is possible. Therefore, to prevent of the arteries occlusion, the study of the effect of rehabilitation exercises can improve the function, structure of blood vessels and their blood flow by modifying the biomechanics of blood flow. In this study, the effect of eight weeks of aerobic exercise on selected biomechanical variables of bilateral femoral artery blood in middle-aged men up to seven days after coronary angioplasty was investigated.
Methodology
This research is quasi-experimental, prospective with pre-test and post-test design. Thirty patients with coronary angioplasty who underwent coronary angioplasty, ranging in age from 45 to 60 years, were among the patients referred to the Tehran Cardiac Rehabilitation Clinic in two experimental and control groups (15 people in each group). Systolic and diastolic blood flow velocity, pressure, and intensity were measured before and after exercise. The aerobic exercise program was performed according to ACSM instructions for eight weeks and three sessions per week, each session lasting 40 minutes on three treadmills, an arm ergometer and a workhorse, for each patient. The control group was selected from those who did not want to do a rehabilitation program and during the program they were asked not to do any specific sports activities and were only advised to walk three days a week. To determine the normal distribution of data from Shapiro-Wilk test and Leven test to examine the variance of the data and the homogeneity of the data of the subjects in the experimental and control groups and Analysis of covariance, paired t-test and Will Coxon at the level of 0.05 were used for significance.
Results
The participants in the experimental and control groups were slightly overweight and the body surface area of the participants in the experimental group was larger than the control group. In these subjects, resting heart rate and systolic and diastolic blood pressure were at the same level in both groups; But the maximum heart rate of the control group was lower than the experimental group.The results showed that there was no significant difference between the experimental and control groups in the effect of aerobic exercise on the variables of blood flow velocity, blood pressure and blood flow intensity in the systolic and diastolic phases.
Conclusion
The effect of exercise on the experimental group was not confirmed, this could be due to heart disease and structural changes in the arteries due to their nature (increased vascular stiffness and decreased elasticity of arteries, especially in peripheral arteries) due to heart disease. Vascular as well as the effect of aging on blood function and consequently its biomechanical variables. It can be concluded that in order to increase the effect of rehabilitation exercises on peripheral arteries than central arteries, more intensity and duration of training is required to achieve the desired result.
