When energy is produced by in the presence of oxygen it is known as aerobic metabolism.
This system uses carbohydrates and fats. The only by-products of this process are carbon dioxide and water, which your body disposes of by breathing and sweating. Aerobic metabolism is important in everyday activities and long distance exercises.
Walkers and runners want to use aerobic metabolism for energy because it results in less muscle soreness afterwards and it makes the body dip into its stored sugar and fat to burn. Walkers achieve this zone by walking at a comfortable to brisk pace where you may be breathing a little hard but still able to speak in full sentences.
This is also known as the "fat-burning zone," as this system is the only one that uses fat for fuel. Runners use aerobic metabolism when they maintain a steady pace to complete there race. Here are some other activities that will help you get into your fat burning zone:
- Group exercise classes (step, low/high aerobics, boxing)
- Cross Training
It is also important to note how efficiently our body uses its fuel. Some people have a slower system and therefore burn less calories. Increasing you muscle mass will help this system run smoothly. Muscles help to burn calories even at rest and you will be better able to perform your daily exercises.
