Background
As is well known, the hypoxia environment has damage to metabolic changes of physical skills and also has damage resistance, and the key points are factors such as the degree and duration of hypoxia occurrence, so that proper hypoxia training has very remarkable effects of improving the anti-hypoxia capability of organisms and strengthening physique. In the practice of sports physiology, the effect of the hypoxia training mode of plateau training or simulated plateau training on the aspects of improving the sports performance and the working capacity, building up body and losing weight and the like of special professionals (such as athletes, pilots, astronauts, divers, plateau workers, fitness personnel and the like) is proved to be effective, and some clinical medical practices in recent years also show that the hypoxia training can improve the number of red blood cells, hemoglobin, hematocrit, blood circulation and oxygen utilization capacity of a human body. The 'influence of high oxygen recovery on the activities of skeletal muscles SDH and MDH of hypoxia-trained rats' published in the journal of sports journal of 2009 7 by Pongyang Kanget al indicates that high oxygen can improve blood oxygen tension, increase blood oxygen content and tissue oxygen storage amount, improve the ischemia and anoxia state of an organism and improve tissue metabolism; high oxygen can rapidly improve the oxygen deficiency condition and the energy metabolism mode of the organism, thereby improving the metabolism condition of free radicals of the organism. Therefore, the oxygen supplementation can antagonize free radicals to directly attack the ultrastructure of the cell, and the integrity of the cell structure and the normal exertion of the functions thereof are ensured; and prevents free radicals from damaging the structure of the enzyme, resulting in a decrease in the activity of the aerobic metabolic enzyme. The 'influence of high oxygen gas supplement on relevant indexes of recovery after human body exercise' published in the journal of China sports coach (4 th year 2020) by Dianthus superbus et al indicates that high oxygen gas supplement has a certain positive effect on relevant indexes of recovery after human body exercise, and is a noninvasive and effective intervention means for recovery of organisms after exercise.
The intermittent high-hypoxia training utilizes the principle, requires the simulation of the environments of hypoxia and low pressure in high altitude areas to achieve the training effect of promoting cell perception and adapting to an oxygen change mechanism, effectively improves the body function, and improves the tolerance of the body adapting to the hypoxic environment. The current intermittent high-low oxygen training is proved by medicine and physiology, has obvious improvement effects on hypertension, hyperlipidemia, arteriosclerosis, cardiac muscle function, male sperm quality, hematopoietic capability and human brain cognition of partial crowds, and can be used for improving the functions of human bodies, enhancing the immune system, the nonspecific compensation capability and the aerobic output of the human bodies.
