The Claim

In young men with obesity, high-intensity interval running results in a significantly higher percentage of energy derived from lipids during the post-exercise recovery period (37.94 ± 14.21%) compared to isocaloric moderate-intensity continuous running (30.09 ± 13.54%), with a p-value of 0.020, indicating greater relative fat oxidation after high-intensity interval training despite equivalent total energy expenditure during exercise.

What the research says

Supports is higher

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

Challenges

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

When young guys with obesity do intense burst running, their bodies burn a bigger share of fat in the hours after the workout compared to when they do steady, moderate jogging—even if both workouts burn the same total calories.

See the scientific wording

In young men with obesity, high-intensity interval running leads to a higher percentage of energy derived from lipid during the post-exercise recovery period (37.94 ± 14.21%) compared to isocaloric moderate-intensity continuous running (30.09 ± 13.54%), with a statistically significant difference (p = 0.020), indicating a greater relative reliance on fat as fuel after HIIT despite equal total energy expenditure during exercise.

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

    The study found that after intense interval running, young men with obesity burned a higher percentage of fat during recovery compared to steady, moderate running—even though both workouts burned the same total calories.
