What are the indicators of aerobic exercise?

Everyone exercises to keep their body strong and healthy. However, everyone should be careful about aerobic exercise. There are certain indicators. You cannot exercise without control every day, as this will cause a large loss of water in the body, thus causing certain harm. This makes everyone very distressed. What kind of indicators are not excessive? Let me explain it to you below.

Many people know that "aerobic exercise" is good for the body, but most people cannot clearly explain what "aerobic exercise" is. Some people even intuitively think that aerobic exercise is exercising in an environment with sufficient oxygen. In fact, the standard for measuring whether it is "aerobic exercise" is heart rate.

Professor Zhao Hongbin, former director of the diet therapy teaching and research department of the China Tourism College and lecturer of the International Advanced Acupuncture Class of the Esperanto Association of the Chinese Academy of Sciences, told reporters: Exercise when the heart rate is maintained at 150 beats/minute is aerobic exercise, because at this time the blood can supply enough oxygen to the myocardium; if the heart rate reaches 150-160 beats/minute, the blood is no longer supplying sufficient oxygen to the myocardium, and it is semi-aerobic exercise; if the heart rate reaches above 160 beats/minute, it is anaerobic exercise, that is, the oxygen in the blood is no longer in short supply for the myocardium.

Metabolism requires the participation of oxygen. Aerobic exercise, due to the sufficient oxygen, can completely metabolize the nutrients in the body, that is, to achieve the final metabolism - the nutrients are decomposed into carbon dioxide and water. Carbon dioxide is expelled from the body through breathing, while water enters through the mouth and exits through breathing, sweat, urine, and defecation. Due to lack of oxygen, anaerobic exercise cannot completely break down substances in the body into carbon dioxide and water during metabolism. Instead, it produces ethanol, acetic acid, lactic acid and many other acids that are harmful to the human body. People feel sore legs when they go up stairs or walk, which is caused by the body being in an anaerobic state and excessive lactic acid.

The pH value of healthy human body fluids is slightly alkaline, at 7.4. Large amounts of ethanol, acetic acid and lactic acid can make body fluids acidic, causing acidosis, and in severe cases even death. Anaerobic exercise not only harms the heart, but also causes metabolic problems throughout the body. One of the reasons for sudden death during intense exercise is the damage that anaerobic exercise causes to the body. In addition, phenomena such as "death from overwork", overuse of the brain, and fatigue syndrome that occur in the workplace are all related to this insufficient oxygen supply to the body.

It is often said that "exercise should be moderate" is based on the above reason, and the amount of exercise also varies from person to person. For ordinary people, how to grasp this degree? Professor Zhao Hongbin tells readers that to maintain an "aerobic" state during exercise is to stop when you sweat slightly, but not to sweat profusely. In addition, whether the fatigue caused by exercise can be eliminated the next day is also a criterion for measuring whether it is aerobic exercise: if you feel tired after exercise but can recover the next day, it is normal; if the fatigue cannot be eliminated on the second day, it means that the exercise is excessive and has exceeded the scope of aerobic exercise.

The above is the editor’s explanation of the indicators of aerobic exercise. So everyone must remember that even if you love sports, you must control the amount appropriately and not do too much intense exercise that will overwhelm your body. There is another point that the editor would like to remind everyone not to forget to replenish water after sweating a lot. There must be gains and losses, otherwise your body will feel tired and unmotivated.
