The Claim

In patients with coronary artery disease, total energy expenditure is a more important determinant of improvements in peak oxygen consumption (VO2peak) than the exercise intensity pattern (high-intensity interval training vs. moderate-intensity continuous training), as differences in VO2peak improvement between HIIT and MICT are no longer observed when exercise protocols are matched for caloric expenditure.

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 heart patients, how much total energy you burn during exercise might matter more than whether you do intense bursts or steady workouts — when both types burn the same calories, they seem to help your fitness just as much.

See the scientific wording

Total energy expenditure may be a more important determinant of improvements in peak oxygen consumption (VO2peak) than exercise intensity pattern (HIIT vs MICT) in patients with coronary artery disease, as the apparent superiority of HIIT disappears when protocols are isocaloric.

    When both workouts burn the same number of calories, intense short bursts of exercise aren't better than steady, moderate exercise for improving heart fitness in heart disease patients.
