Effect of Combined Resistive and Aerobic Exercise versus Aerobic Exercise Alone on Coronary Risk Factors in Obese Coronary Patients

Abstract

Objective: To study the effect of combined resistive and aerobic training versus aerobic training alone on coronary risk factors in obese coronary patients. Design: Randomized clinical trial. Setting: Outpatient setting, Cardiac Rehabilitation Unit, Montefiore Medical Center, NY. Participants: 50 coronary artery disease patients completed the study and were randomized to group I aerobic exercise (n=25) and group II combined resistive and aerobic exercise (n= 25). Interventions: All patients had dietary counseling, stress management and aerobic exercise 3 times per week for 36 sessions. Group II added resistive exercise from the 18th session. All exercises were telemetry monitored. Main Outcome Measures: Body weight, body mass index, percent body fat, lipid profile, 1 repetition maximum for muscular strength, and cardiovascular conditioning parameters were measured for all patients at baseline and at the end of the study. Results: Strength gains for group II were greater than for group I on the 3 resistance machines (P
