Adding resistance exercises to interval cycling to boost fitness and muscle in women with coronary artery disease
Resistance Training Among Women With Coronary Artery Disease
This trial will test whether swapping some cycling intervals for strength exercises helps women with coronary artery disease improve aerobic fitness and build muscle.

What this trial studies
The study first uses a crossover feasibility phase to compare immediate heart rate, blood pressure, and perceived exertion during two resistance training tempos (normal-speed vs prolonged-eccentric). After confirming short-term safety and feasibility, participants are randomized into one of three 12-week, parallel groups: aerobic interval training (AIT) alone, AIT plus normal-speed resistance training, or AIT plus slow-speed (prolonged-eccentric) resistance training. Interventions consist of three supervised sessions per week (36 total) with AIT performed on a cycle ergometer guided by heart rate reserve and resistance exercises including squats and pulling movements with weights. Primary outcomes include changes in aerobic capacity and muscle mass, with secondary outcomes of acute hemodynamic responses and perceived exertion.
Who should consider this trial
Good fit: Women with documented coronary artery disease who are clinically stable (at least 1 month since myocardial infarction or elective PCI and at least 3 months since cardiac surgery) and eligible for cardiac rehabilitation are ideal candidates.
Not a fit: People who are clinically unstable, have contraindications to resistance training per American Heart Association guidelines, are too early after cardiac events, or are pregnant are unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, combining resistance training with reduced aerobic intervals could improve aerobic capacity and increase muscle mass, potentially enhancing functional ability and quality of life for women with coronary artery disease.
How similar studies have performed: Previous research supports that appropriately prescribed resistance training is safe in cardiac rehabilitation and improves strength and quality of life, but combining reduced AIT with prolonged-eccentric resistance training in women is relatively untested.
