The Claim

In young men with obesity, high-intensity interval running at 90% of VO2max requires significantly less time (29.50 ± 3.04 minutes) compared to moderate-intensity continuous running at 60% of VO2max (37.60 ± 4.56 minutes) to expend approximately 300 kcal, indicating that high-intensity interval training (HIIT) is more time-efficient for achieving equivalent acute energy expenditure.

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

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 young guys with obesity, doing short bursts of intense running burns 300 calories faster than jogging steadily — about 8 minutes less effort for the same result.

High-intensity interval running at 90% VO2max requires significantly less time (29.50 ± 3.04 minutes) than moderate-intensity continuous running at 60% VO2max (37.60 ± 4.56 minutes) to expend approximately 300 kcal in young men with obesity, demonstrating that HIIT is more time-efficient for achieving the same acute energy expenditure.

1 study

  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 compared a short, intense workout to a longer, easier one, both burning about 300 calories. It found the intense workout took less time, which supports the claim.
