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.

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 counselling, 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.

Results: Strength gains for group II were greater than for group I on the three resistance machines (P<0.01). Percent body fat was reduced for group II after training (P<0.01) with significant difference in between groups (P<0.01). The relative gain in lean mass was greater in group II (P=0.0006). Group II only had decreased cholesterol, triglyceride, and low density lipoprotein (P<0.05). High density lipoprotein significantly increased in both groups (P<0.05). All cardiovascular conditioning parameters significantly diminished in both groups after training (P<0.05). Group II had lower exercise systolic blood pressure (P<0.05) and relatively greater improvement in average work load (P=0.0000).

Conclusions: Combined resistive and aerobic training give better control of coronary risk factors particularly lipid profile and weight in obese coronary patients.
