The Claim
In young men with obesity, high-intensity interval running leads to a significantly higher rate of lipid oxidation during the 30-minute post-exercise recovery period (1.01 ± 0.43 mg/kg/min) compared to isocaloric moderate-intensity continuous running (0.76 ± 0.46 mg/kg/min), indicating an acute enhancement of fat metabolism after exercise despite equivalent energy expenditure during the activity.
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.
When young guys with obesity do intense burst running, their bodies burn more fat in the half-hour after the workout than when they jog steadily — even if both workouts burn the same number of calories.
See the scientific wording
In young men with obesity, high-intensity interval running increases the rate of lipid oxidation during the 30-minute recovery period to 1.01 ± 0.43 mg/kg/min, which is significantly higher than the 0.76 ± 0.46 mg/kg/min observed after isocaloric moderate-intensity continuous running, indicating that HIIT acutely enhances fat-burning metabolism post-exercise despite similar total calorie expenditure during the workout.
What the research says
1 studyThe study found that short bursts of intense running burn more fat after the workout than steady, moderate running—even when both burn the same number of calories during exercise.
