The Claim

In trained adult males, high-intensity interval training and high-intensity circuit training result in significantly greater carbohydrate oxidation during the 60-minute post-exercise recovery period compared to moderate-intensity continuous training, with measured rates of 2.57 mg/kg/min and 2.89 mg/kg/min respectively, versus 1.25 mg/kg/min following moderate-intensity continuous training, suggesting sustained activation of glycogen resynthesis pathways after high-intensity exercise sessions.

Supports is higher

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

In plain English

After tough workouts like sprint intervals or fast-paced circuit training, fit guys burn more carbs in the hour after exercise compared to easier, steady workouts — which might mean their bodies are working harder to refill energy stores.
