Aerobic vs. Anaerobic

Aerobic vs. Anaerobic. Aerobic & Anaerobic = 2 different ways energy is produced. Energy produced aerobically so long as there is enough oxygen supplied to the exercising muscles by the cardiovascular system.

  1. Aerobic vs. Anaerobic

  2. Aerobic & Anaerobic = 2 different ways energy is produced • Energy produced aerobically so long as there is enough oxygen supplied to the exercising muscles by the cardiovascular system. • The higher the C.V. system, the longer the body will stay in aerobic mode during your workout. • When your muscles aren’t getting enough oxygen through aerobic, then you get energy anaerobically. • At a low rate of exercise, your muscles get plenty of oxygen. At some point between 50-85% of max. capacity, exercising muscles shift to anaerobic since oxygen is getting scarcer.

  3. The Difference • Anaerobic system burns glucose (from carbohydrates), and produces lactic acid which leads to burning and fatigue. • Aerobic system burns glucose and fat too. This combination produces energy. The waste product of aerobic exercise is carbon dioxide and water which don’t lead to quick fatigue.

  4. CONCLUSION • 1. Aerobic exercise will burn more fat and calories-you can do this for longer periods of time since no lactic acid accumulates. • 2. If you suddenly shift into anaerobic mode you will get lactic acid, thus quicker fatigue and small caloric expenditure.

  5. “The Anaerobic Threshold” • How will we know when our body shifts into anaerobic?? • 1. breathlessness • 2. talk, but not sing • 3. burning sensation

  6. Achieving Overall Fitness • Best way to achieve overall fitness (for general public) is to exercise to the anaerobic threshold, and then slow down and repeat cycle. For older people, exercising at a comfortable aerobic pace is fine. • Pro Athletes-college, competitive high school should exercise anaerobically as well.
