Introduction to Aerobic Exercise

There are three kinds of fuel used during an aerobic activity: carbohydrates (become the principal source of fuel whenever the physical activity is high in intensity, i.e., over 85% of maximum heart rate, which only athletes usually reach), fat (used by the body during a prolonged work out, the one the majority of people use), and proteins (do not provide more than 10 to 15% of the total energy required during the activity).

Knowing that, we clearly see that the power of the aerobic system depends on the maximum rate at which the body can transport and consume oxygen. Therefore, an aerobic exercise helps you to use oxygen more efficiently by reaching and maintaining your Target Heart Range (THR), i.e., a safe range of heart beats per minute during exercise because it is the heart that pumps the blood.

Aerobics activities should be performed for a minimum of 20 to 30 minutes, at least 3 times a week to maintain a good body condition, more often in order to burn fat.
