Hemodynamic, Autonomic, Ventilatory, and Metabolic Alterations After Resistance Training in Patients With Coronary Artery Disease
Key result
Combined resistance and aerobic training for 8 weeks increased load tolerance (P<0.01) and parasympathetic tone (P<0.05), and decreased hemodynamic response (P<0.01) versus aerobic training alone.
Why the study?
Does adding an 8-week resistance training program to aerobic training improve hemodynamic, autonomic, and metabolic responses during exercise in male patients with coronary artery disease?
Population
20 male subjects with coronary artery disease, mean age 61.1 ± 4.7 years.
Comparison
8-week resistance training program added to an… vs Aerobic training program alone.
Design
RCT, randomly assigned
Follow-up

Implication
Low-intensity resistance training added to aerobic programs may be feasible in CAD; leaves open effects on clinical outcomes in larger trials.

P
Population
20 male subjects with coronary artery disease (mean age 61.1 years) who underwent an 8-week training program.
I
Intervention
8-week resistance training program (low-intensity 30% of 1 repetition maximum, high-repetition 3 sets of 20 repetitions) added to an aerobic training program.
C
Comparator
Aerobic training program alone.
O
Outcome
Hemodynamic, autonomic, and metabolic responses (heart rate, stroke volume, cardiac output, minute ventilation, blood lactate, RMSSD, SD1) during exercise on a cycle ergometer and a 45-degree leg press.surrogate
Main Result
p-value: p=<0.01
Adding an 8-week low-intensity, high-repetition resistance training program to aerobic training attenuates hemodynamic stress and improves autonomic and metabolic responses during exercise in men with coronary artery disease.

Caruso et al. (2016) conducted an RCT in coronary artery disease (n=20). Combined training (resistance + aerobic) vs. Aerobic training was evaluated on Hemodynamic, autonomic, and metabolic responses during exercise (p=<0.01). Combined resistance and aerobic training for 8 weeks increased load tolerance (P<0.01) and parasympathetic tone (P<0.05), and decreased hemodynamic response (P<0.01) versus aerobic training alone.
