Aerobic and Anaerobic Exercise

Welcome to 5.14 Fitness,

This post will be again another from the Back To Basics series, in which I describe and explain basic ( as you could have guessed) must know factors on health and fitness. The foundation blocks of what fitness and health is, this post in particular will be based on aerobic and anaerobic exercise.


Aerobic essentially means exercising with oxygen

The scientific equation for this is :

Oxygen + Glucose --> (Energy) + Water + Carbon Dioxide

When you exercise over a long period of time and are constantly breathing you are exercising aerobically. Your muscles are performing an activity that requires stamina, therefore testing the targeted areas muscular endurance so they will require oxygen all the time to be able to respire in order to produce the energy they need to keep moving and to stop lactic acid from building.


Anaerobic means the opposite of aerobic; exercising without oxygen

The scientific equation for this is :

Glucose --> (|Energy) + Lactic acid

It is only possible to perform exercises that last a short periods of time. If your body does not have enough oxygen to respire efficiently, the lactic acid formed begins to poison muscles causing them to become fatigued resulting in you having to slow down or stop exercising. Consequently anaerobic techniques are far more common in sports relying on power or muscular strength, as breathing is said to slow down the body and break up fluid motions.

Oxygen debt

Oxygen debt is the amount of extra oxygen that is owed to the body after you have finished exercising anaerobically. Restoring oxygen debts back to a normal amount after a shortage due to the high heart rate is completed by taking in heavy or deep breathes to ensure as much oxygen is inhaled as possible. By getting oxygen back into fatigued muscles will remove the poison in the muscles ( lactic acid) helping to stop them from aching whilst the body recovers.


The vast majority of sports are a mixture of both types of exercise. You may use maximum effort in a sprint in a sport like football, to receive the ball (anaerobic) but then slow down again when you are tracking back or getting back into position (aerobic). It is necessary to study your sport to see what method of exercise is needed, so you can then adjust your training accordingly.
