Anaerobi c High-intensity, short duration activity such as heavy weight training (maximal load). Up to approximately 10 seconds of activity Glycolysis: Uses the breakdown of carbohydrates (glucose). Anaerobi c Moderate to high-intensity, moderate duration activities such as running a 400m or 800m race. 30 seconds to 3 minutes of activity Oxidative: Relies primarily on carbohydrates and fats.
