Many sports enthusiasts have heard of "altitude training", which is widely used in the training process of many athletic events such as middle and long distance running, swimming, cycling, cross-country skiing, and water sports. A large number of experimental studies and exercise practices have proved that exercise training under high altitude hypoxia is beneficial to improve the body's ability to resist hypoxia.
Recently, the “low-oxygen training†applied to the gym has been improved by “altitude training†and has attracted the attention of people inside and outside the industry. A few days ago, at the Xiangshan Science Conference and the Cross-Strait Hypoxia Symposium held in Wuwei, Gansu, experts at the meeting suggested that the low-oxygen fitness should be popularized.
Although the traditional plateau training can promote the athletes' oxygen and oxygen-enhancing ability, in the anoxic environment, the recovery of fatigue is slower and the muscle working ability is reduced.
The “hypoxia training†introduced in the gym simulates the low-oxygen environment of “plateau trainingâ€. The artificially manufactured low-oxygen environment or inhaled low-oxygen gas in the plain area makes the oxygen content of the gym lower than normal. Hypoxic air has a good health care effect on the human body, can improve the body's immunity, increase oxygen transport and liver detoxification, and improve athletes' training ability. Former Soviet medical experts have invented "hypoxia therapy", allowing patients to repeatedly inhale only 10% oxygen content of hypoxic air, to activate the potential of the human hypoxic self-defense system, to achieve the purpose of disease treatment, disease-free and physical. This method has a significant effect on the treatment of cardiovascular, respiratory and nervous system diseases, as well as relieve pain and eliminate fatigue.
Hypoxic fitness can achieve the effect that ordinary outdoor sports can't achieve. The fitness person either goes to the gym or climbs the plateau to experience the feeling of "low oxygen" exercise.
In the fitness industry in New York, USA, hypoxic fitness is not a new concept, it has long been the most popular fitness exercise. Since hypoxic fitness must be carried out in an artificial hypoxic gym, the price is naturally higher than that under normal conditions. In general, the cost of hypoxic exercise is about double that of normal fitness ; however, with the rapid increase in the number of people participating in hypoxic fitness and the continuous expansion of the fitness range, the cost of hypoxic fitness is also decreasing.
The first advantage of hypoxic fitness lies in the fact that when it is in a "low oxygen state", the human body adapts to a hypoxic, low-pressure living environment, the heart rate is correspondingly accelerated, the blood output of the heart is increased, and the red blood cells and hemoglobin in the blood are also increased. This enhances the ability of the blood to transport oxygen, and the function of blood to the body's tissues is bound to increase. As a result, the body's utilization of oxygen is correspondingly increased. The exerciser is exercising under hypoxic conditions, and the amount of activity of the lungs becomes large, which can expand the arteries and accelerate the blood circulation of the whole body. Therefore, the fitness under hypoxic conditions has the advantages of increasing the number of red blood cells, enhancing the function of the immune system, and enhancing the utilization of oxygen by brain tissue and muscles, compared with the fitness in the normal state. It takes only half of the time to obtain The same fitness effect.
Second, hypoxia can accumulate the necessary carbon dioxide in the body. Human blood must have 2% oxygen and 65% carbon dioxide. If the body's carbon dioxide content is too low, it will cause imbalance of gas in the body, causing alkalemia with more acid and alkali. This will destroy the normal metabolic process, damage the human nervous system and immune function, and ultimately lead to the loss of self-defense ability against the disease.
Overview of the advantages of hypoxic training:
1. Strengthen cardiopulmonary: initial stress rate can be accelerated, chronic hypoxic exposure can reduce heart rate, improve cardiac contractility and diastolic function, and lower blood pressure ; effectively increase maximal oxygen uptake, improve lung ventilation capacity and vital capacity ; improve heart and lung capacity transport system for oxygen.
2 , accelerate fat burning: increase the basal metabolic rate, promote fat, protein metabolism, increase energy consumption ; reduce appetite.
3 , improve function: enhance muscle strength, stimulate muscle cell capillaries, mitochondria proliferation, activate oxidase activity.
4 , physical training: hypoxia makes the oxygen transport system more effective, can increase muscle strength and endurance up to 40%; make effective training time up to 50% .
5 , optimize blood: promote EPO synthesis and release, increase RBC ( red blood cell ) count, Hct ( hematocrit ) , that is, the amount of HbO ; promote the synthesis and release of human growth hormone.
6. Enhance immunization: In the treatment of cardiopulmonary diseases and cardiovascular diseases or other difficult medical conditions in Europe, hypoxia training is often used as an effective means to improve the function of the human immune system.
