The aerobic energy system
It requires oxygen, which resynthesizes ATP to create the energy required. It is used in lower intensity exercise and provides the energy for most human activity during our lives it is also important in the recovery from exercise of all intensities.
Anaerobic exercise
It is a physical exercise intense enough to cause lactate (lactic acid). to form. It is used by athletes in non-endurance sports to promote strength, speed and power and by body builders to build muscle mass. Muscle energy systems trained using anaerobic exercise develop differently compared to aerobic exercise, leading to greater performance in short duration, high intensity activities, which last from mere seconds to up to about 2 minutes. Any activity lasting longer than about two minutes has a large aerobic metabolic component.
What is the difference between aerobic and anaerobic exercise?
In the simplest terms the difference comes down to the oxygen. With aerobic exercise oxygen is carried through your breath to the muscles giving them the energy needed to sustain the effort. Oxygen is not present with anaerobic exercise.
So, what is the main factor that determines whether our body uses aerobic metabolism or anaerobic metabolism in obtaining energy?
ReplyDeleteWhat are the advantages of aerobic metabolism over anaerobic metabolism?Explain them.
1.Anaerobic metabolism can only use glucose and glycogen, while aerobic metabolism can also break down fats and protein.
DeleteAerobic exercise: are medium or low intensity and long-lasting exercises, where the body needs to burn hydrates and fats to obtain energy and for this it needs oxygen. Examples of aerobic exercises are: running, swimming, cycling, walking, etc.
Anaerobic exercise: they are high intensity exercises and of short duration. Here oxygen is not needed because the energy comes from immediate sources that do not need to be oxidized by oxygen, such as muscle ATP, PC or phosphocreatine and glucose. They are examples of anaerobic exercises: doing weights, speed races and exercises that require great effort in a short time.
2.The usual aerobic practice provides the body with greater resistance, prevents obesity and is beneficial for the cardiovascular system. It allows you to lose weight by reducing body fat, improves cardiovascular function and lung capacity,decreases in the medium term, blood pressure in hypertensive patients and helps reduce cholesterol levels, positively influences mood, improving self-esteem, it improves the intellectual capacity, firms the tissues and skin and it increases the reabsorption of calcium by the bones, strengthening them and decreasing the risk of fractures.
