The Claim

High-intensity interval training leads to greater improvements in peak oxygen consumption (VO2peak) compared to moderate-intensity continuous training in patients with coronary artery disease, with a mean difference of 2.11 mL/kg/min (95% CI: 1.14 to 3.07), based on low-certainty evidence from randomized controlled trials.

What the research says

Supports is higher

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

Supports
42score
Challenges
0score

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

Quantitative
1 study reviewed
In plain English

Doing short bursts of intense exercise might boost heart fitness more than steady, moderate workouts for people with heart disease — on average by a small but measurable amount.

  1. Study: High-intensity interval training versus moderate-intensity continuous training on exercise capacity and health-related quality of life in patients with coronary artery disease: An updated systematic review and meta-analysis.

    The study found that high-intensity interval training improves oxygen use in heart patients more than moderate exercise, just like the claim says.
