The Claim

In trained adult males, total carbohydrate oxidation during a single session of high-intensity circuit training is significantly greater than during moderate-intensity continuous training, with measured rates of 32.92 mg/kg/min and 12.98 mg/kg/min respectively, indicating a greater reliance on glycolytic energy systems during high-intensity exercise.

In plain English

When fit guys do intense circuit workouts, their bodies burn way more carbs during the workout compared to when they do steady, moderate exercise — like 33 vs 13 carbs per minute for every kilo they weigh.

In trained adult males, the total carbohydrate oxidation during a single session of high-intensity circuit training is significantly greater than during moderate-intensity continuous training, with cumulative rates of 32.92 mg/kg/min versus 12.98 mg/kg/min, reflecting the greater reliance on glycolytic energy systems during high-intensity efforts.
