The Claim

Excess post-exercise oxygen consumption (EPOC) results in a sustained elevation in metabolic rate for several hours following a short, high-intensity exercise bout.

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.

How it works
2 studies reviewed
In plain English

After a short, high-intensity workout, the body continues to burn calories at a higher rate than at rest for several hours due to increased oxygen consumption.

See the scientific wording

The afterburn effect (EPOC) keeps metabolism elevated for hours after a short, high-intensity workout.

Why this might work

After a short, intense workout, the body uses extra oxygen to rebuild energy stores and reset ion levels in muscle cells, which keeps metabolism high for hours.

What the research says

2 studies

  1. Study: Isocaloric High-Intensity Interval and Circuit Training Increases Excess Post-Exercise Oxygen Consumption and Lipid Oxidation Compared to Moderate-Intensity Continuous Training

    After intense short workouts, your body keeps burning more calories for up to an hour because it needs extra oxygen to recover — this study proved that better than easy workouts.

  2. Study: Acute interval running induces greater excess post-exercise oxygen consumption and lipid oxidation than isocaloric continuous running in men with obesity

    After a short, intense workout, your body keeps burning extra calories for a while—even after you stop exercising. This study found that high-intensity running made people burn more extra calories afterward than a longer, slower run that used the same amount of energy during the workout.
