Resistance Training Added to Aerobic Interval Training to Improve Aerobic Capacity and Muscle Mass in Women With Coronary Artery Disease

Summary

The goal of this clinical trial is to find out whether partly replacing aerobic interval training (AIT) with resistance training (RT) leads to greater improvements in physical fitness and muscle mass in women with coronary artery disease (CAD) during cardiac rehabilitation. The main questions this study aims to answer are: * Does combining RT (squats and pulling exercises with weights) with a reduced amount of AIT (cycling) improve aerobic fitness in the same way as AIT alone? * Does the combined training lead to greater improvements in muscle mass compared with AIT alone? * Does slow-speed RT (slower lowering phase) result in lower heart rate and blood pressure during exercise compared with normal-speed RT? Researchers will compare three exercise programs: * AIT only (control group), * AIT combined with normal-speed RT (1-second lifting, 2-second lowering), * AIT combined with slow-speed RT (1-second lifting, 5-second lowering). Participants will take part in a 12-week cardiac rehabilitation program and will train three times per week. At the start and end of the program, participants will complete a cycling fitness test, body composition assessment, blood sampling, two strength tests, and quality-of-life questionnaire.
