Aerobic interval training (AIT) at 85-90% VO2peak improves cardiovascular risk markers and coronary flow reserve in overweight patients with stable coronary artery disease (CAD).
If you have stable heart disease, high-intensity interval training (AIT) is more effective than moderate continuous exercise for improving your heart's health markers. The protocol involves supervised sessions at 85-90% of your maximum aerobic capacity, performed 3 times a week initially, then reduced to 2 times a week for maintenance.
Several smaller studies in patients with metabolic syndrome, CAD, congestive heart failure (CHF), hypertension and diabetes have shown that aerobic interval training (AIT) is superior to moderate continuous training in improving VO2peak and other cardiovascular risk markers such as endothelial function, glucose tolerance, hypertension and dyslipidemia.
Why this rating
The paper is a protocol describing a randomized controlled trial; it cites previous smaller studies but does not present the final results of this specific trial.

- Bariatric surgery (VSG and RYGB) is the most effective and sustainable treatment for obesity, producing marked and sustained weight loss that non-surgical interventions cannot match.Strong
- Severely protein-deficient diets (2–3% energy) induce lean body mass loss and metabolic imbalance, whereas adequate protein intake (0.66 g/kg/d minimum) is a prerequisite for maintaining muscle, bone, and physiological function.Strong
- For patients with Class III obesity (BMI >39.9 kg/m2), metabolic bariatric surgery (MBS) is significantly more effective than any currently approved medication, with BilioPancreatic Diversion (BPD) showing the highest estimated weight loss.Strong
