What is the role of anaerobic exercise? Can anaerobic exercise increase muscle?

If you want to lose weight, you should do anaerobic exercise together with aerobic exercise, so that the weight loss effect will be better. So what is the role of anaerobic exercise? Can anaerobic exercise help you build muscle? Let's take a look below.

Anaerobic exercise doesn't burn fat, but it can build muscle and increase muscle mass. Even if the muscles are not exercising, they still consume energy to maintain body temperature and body function. Therefore, the higher the muscle content, the better the basal metabolism will be, and it will be easier to lose weight.

Among all anaerobic exercises, muscle training is the most effective in increasing muscle mass. This is because increasing the burden on muscles will cause substances such as lactic acid to accumulate in the muscles. At this time, the brain will receive this instruction and secrete growth hormones that promote muscle formation.

The biggest feature of anaerobic exercise is that the oxygen intake during exercise is very low. Due to the excessive speed and explosive power, the sugar in the human body does not have time to be decomposed by oxygen, and has to rely on "anaerobic energy supply". This kind of exercise will produce too much lactic acid in the body, resulting in muscle fatigue that cannot last long, muscle soreness and shortness of breath after exercise. In fact, a large amount of intermediate metabolites such as pyruvic acid and lactic acid are produced during fermentation, which cannot be eliminated through breathing. These acidic products accumulate in cells and blood, becoming "fatigue toxins", which will make people feel tired and weak, muscle soreness, and respiratory and heartbeat acceleration and arrhythmia. In severe cases, acidosis and increased liver and kidney burden will occur.

Common anaerobic exercises include: sprinting, weightlifting, throwing, high jump, long jump, tug of war, push-ups, diving, muscle strength training (prolonged muscle contraction), etc.
