Anaerobic threshold

Anaerobic threshold. Muscles burn energy in two ways, aerobically (with oxygen) and anaerobically (without oxygen). Your body's anaerobic threshold represents the point at which you begin working your muscles without oxygen, usually in response to bursts in activity such as a fast sprint. Anaerobic threshold varies but is generally lower for less active people versus more active people.
