  1. Aerobic vs. Anaerobic exercise Exercise falls into two general categories: aerobic and anaerobic. Aerobic exercise is muscle movement that uses oxygen to burn both carbohydrates and fats to produce energy, while anaerobic exercise is muscle movement that does not require oxygen and only burns carbohydrates to produce energy. .

  2. Aerobic vs. Anaerobic • Aerobic exercise is muscle movement that uses oxygen to burn both carbohydrates and fats to produce energy • In practice, aerobic exercise means activities such as walking, bicycling or swimming that temporarily increase your heart rate and respiration. • Aerobic exercise (also known as cardiovascular exercise) builds your endurance.

  3. Anaerobic vs. Aerobic • Anaerobic exercise typically means activities such as weightlifting and push-ups and sit-ups, which builds muscle and physical strength through short bursts of strenuous activity. • An ideal exercise program should include both aerobic and anaerobic exercise.

  4. Anaerobic Metabolism • Fast twitch muscle operates using anaerobic metabolic systems. • Any recruitment of fast twitch muscle fibers lead to increased anaerobic expenditure. • Intense exercise lasting upward of about 4 minutes (e.g., a mile race) may still have a considerable anaerobic energy expenditure component.

  5. Anaerobic Exercise • In sports which require repeated short bursts of exercise the anaerobic system enables muscles to recover for the next burst. • Training for many sports demands that both aerobic and anaerobic systems are developed.

  6. Two types of anaerobic systems • ATP • Stored in limited quantities with the muscle cells • Up to 30 seconds • Anaerobic Glycolysis • Uses glucose (and glycogen) as a fuel in the absence of oxygen • Up to 4 minutes *When ATP is needed at rates that exceed those provided by aerobic metabolism; the consequence of rapid glucose breakdown is the formation of lactic acid (more appropriately lactate at PH levels)
