The Claim

In patients with coronary artery disease, when high-intensity interval training and moderate-intensity continuous training are matched for total energy expenditure, there is little or no difference in the improvement of peak oxygen consumption (VO2peak), with a mean difference of 0.72 mL/kg/min (95% CI: −0.03 to 1.48), based on low-certainty evidence.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

For people with heart disease, short bursts of intense exercise don’t seem to work much better than steady, moderate exercise when both burn the same number of calories — both help a bit, but the difference between them is tiny.

See the scientific wording

When high-intensity interval training and moderate-intensity continuous training are matched for total energy expenditure (isocaloric protocols), there is little or no difference in improvement in peak oxygen consumption (VO2peak) in patients with coronary artery disease, with a mean difference of 0.72 mL/kg/min (95% CI: −0.03 to 1.48), based on low-certainty evidence.

    The study found that when both workouts burn the same amount of calories, high-intensity and moderate-intensity exercises improve heart fitness equally in heart disease patients, just like the claim says.
