A new study, published in the ACSM’s journal, Medicine & Science in Sports & Exercise, shows that coronary artery disease patients should replace their existing aerobic exercise programs with a combined resistance / aerobic training program.
The study looked at various markers of health important to individuals suffering from coronary artery disease.
These markers were:
- Vo2 peak
- Body Composition
- Anaerobic Endurance
- Muscular Strength
- Muscular Endurance
The cross training (combined Resistance and Aerobic training) group demonstrated greater improvements than the aerobic group in every single marker of health.
After 29 weeks:
- Vo2 peak – Improved 18% in the Cross-Training (CT) group and 11% in the Aerobic (AT) group (data)
- Lean Body Mass – The CT group gained close to 4x more muscle mass than the AT group (1.5 kg v.s 0.4 kg) (data)
- Body Fat – The CT group lost 2% body-fat while the AT group lost 0.1% (data)
- Anaerobic Endurance – Insignificant changes in both the AT and CT groups (data)
- Muscular Strength – The CT group increased their leg strength by 18%, while the AT group increased leg strength by only 6% (data)
- Muscular Endurance – Muscular Endurance (tested by Leg Press) improved 100% in the CT group and only 15% in the AT group (data)
The major findings of this study are that replacing two aerobic training (AT) sessions with two Resistance Training (RT) sessions (creating a Cross Training (CT) workout) each week elicited similar or higher changes in cardiovascular fitness (V⋅O2peak) than AT alone (5 sessions per week) with the added benefits of significant gains in muscle strength, local muscle endurance, lean mass accretion and reduction in percent body fat in CAD patients.
These data support the hypothesis that combined RT/AT training (or CT) was superior in eliciting physiological adaptations, with more substantial gains seen with increased volume of RT for lean muscle mass, lower body muscular endurance, VAT, and V⋅O2peak.
