Aerobic exercise can enhance and improve heart and lung function, prevent osteoporosis, adjust psychological and mental state, and consume body fat, which is the main exercise mode of fitness. In short, the so-called "aerobic exercise" refers to a lasting exercise that can enhance the inhalation, transportation and utilization of oxygen in the body.

The opposite of aerobic exercise is anaerobic exercise, which means that muscles perform high-intensity strenuous exercise in a state of "hypoxia". Because the speed is too fast and the explosive force is too strong, the sugar in the human body cannot be decomposed by oxygen, so we have to rely on "anaerobic energy supply". This kind of exercise produces too much lactic acid, which leads to muscle fatigue and even muscle and joint damage, and is not suitable for daily fitness exercise.

Common aerobic exercises include jogging, brisk walking, skating, swimming, cycling, playing Tai Ji Chuan, dancing fitness dance, skipping rope, yangko and table tennis. Anaerobic sports include running, weightlifting, throwing, high jump, long jump, tug-of-war and muscle strength training.

Matters needing attention in aerobic exercise

1. Warm-up activities should be carried out before the start of exercise.

2. After the exercise, relax for 15 minutes, and don't stop exercising suddenly.

3. The amount of exercise should be gradual.

4. For some complications of myocardial infarction and heart failure, it is necessary to effectively control myocardial ischemia and heart failure. After the condition is stable, let the doctor evaluate his situation and then make his own exercise plan.

5. Patients with hypertension should start aerobic exercise after completely controlling their blood pressure.
