Abstract

Introduction: Nowadays, non-communicable diseases due to technological advancement and lifestyle changes in a sedentary, inactive and inactive manner have caused health and wellness problems such as cardiovascular diseases, especially coronary artery diseases. The aim of the present study was to investigate the effect of combined exercise (endurance-resistance) on selected hemodynamic indices, ejection fraction and functional capacity of cardiovascular patients.
Methods: In this study, which was conducted with a pre-test and post-test design with a control group, 24 volunteer patients were randomly divided into 2 combined exercise groups (12 people) and control (12 people). The combined exercise group performed 3 sessions of aerobic and resistance exercises per week for 3 months. The measurements of the variables were performed 24 hours before the first exercise session and 48 hours after the last exercise session. In the inferential statistics section, paired t-test was used to compare intra-group differences and analysis of covariance was used to compare inter-group differences using SPSS version 26 software.
Results: Based on paired t-test, a significant decrease in systolic and diastolic blood pressure, systemic vascular resistance, and a significant increase in ejection fraction, functional capacity, stroke volume, cardiac output, cardiac output index, blood velocity index, and blood acceleration index were observed in the combined exercise group after training (P<0.05). This decrease was not significant in the control group. Covariance analysis showed that the levels of these variables had improved significantly compared to the control group (P<0.05).
Conclusion: In general, the results showed that performing combined endurance and resistance exercises can improve hemodynamic indices, ejection fraction, and functional capacity in cardiovascular patients.
