Research on Low Oxygen Health and Training

Research on Low Oxygen Health and Training:

◆ Zhou Zhaonian, Hypoxia Cardiovascular Laboratory, Chinese Academy of Sciences, Shanghai Academy of Life Sciences, Research on Hypoxia and Health, China Basic Sciences, 2003 (5): 20-25 The article proposes that hypoxia is closely related to human health and has significant implications, involving economic development, disease prevention and control, and improvement of sports levels in western China. Low oxygen and health research is an important topic in the field of life sciences, which has aroused widespread interest among scientists and doctors at home and abroad. In recent years, hypoxia inducible factors, cell apoptosis, and intermittent hypoxia have become hot topics in the study of external hypoxia and health. Today, research on hypoxia and health should also receive attention from the biological and medical communities in China.

Zhou Zhaonian, "A Review of Low Oxygen Physiology Research", published as a special article in the first issue of the 43rd volume of the Journal of Physiology in 2012. Professor Zhou Zhaonian reviewed his journey of conducting research on hypoxia physiology since graduating from university in 1963 and entering a research institute. From the article, it can be seen how low oxygen is closely integrated with the construction of each stage in China, and how it plays a practical role.

◆ Zhang Yi et al., "Cardiac Protection in Intermittent Hypoxia Adaptation," Acta Physiologica Sinica, October 25,  2007, 59 (5): 601-613.  Research has shown that intermittent hypoxia adaptation (IH adaptation), similar to ischemic preconditioning (IPC), and long-term high-altitude hypoxia adaptation (long-term high-altitude hypoxia)

adaptation, LHA)， It has a significant cardioprotective effect, manifested as enhancing myocardial tolerance to ischemia/reperfusion injury, limiting myocardial infarction area and morphological changes, anti apoptosis, promoting the recovery of ischemic/reperfusion cardiac function, and anti arrhythmia.

Hu Yang, Vice President of Beijing Sport University and authority on low oxygen training in China, "Low oxygen Training and Health Promotion", International Symposium on High Altitude Training and Health in China, 2011. The article describes how while low oxygen training is gradually being accepted by athletes, it is also gradually approaching the lives of ordinary people, playing a role in improving their health. At present, low oxygen training is mainly used to improve cardiovascular function, exercise for weight loss, and high-altitude adaptation in promoting health.

Hu Yang et al A New Method of Endurance Training - High Stay Low Training (HiLo) "[J]. Chinese Journal of Sports Science, 2001.21: 66-70 The article explains the application significance of HiLo training method from the perspective of exercise physiology, and summarizes the development status of HiLo training method abroad and the research on the impact of HiLo training method on physiological and biochemical functions.

Zhao Peng, Feng Lianshi Research and Application Progress of New Low Oxygen Training Modes ", Sports Science 2005 (6) National Science and Technology Research and Development Program (2003BA904B03). This article reviews and summarizes the concept and development history of low oxygen training at home and abroad. It summarizes three new low oxygen training modes, namely intermittent low oxygen training, high living low training, and low living high training, and their concepts, principles, content arrangements, advantages, applications, and effects on body functions. It points out the problems in existing research and looks forward to the research prospects.

Wang Ningqi et al., "The Effect of 4-Week Low Oxygen Exercise Combined with Dietary Control on Weight, Blood Lipids, and Insulin Resistance in Obese Youth," Chinese Journal of Sports Medicine, Volume 31, Issue 4, April 2012. Their method involved dividing 18 obese adults into a low oxygen group of 11 and a normoxic group of 7, and conducting a 4-week weight loss training program for 6 days per week. The low oxygen group underwent low oxygen training three times a week, simulating an altitude of 2500-2800m, while the rest underwent normoxic training. The conclusion drawn is that compared with normoxic exercise, 4-week hypoxic exercise significantly reduces the weight and BMI of obese youth. Both 4-week hypoxic exercise and normoxic exercise can reduce the risk factors of type II diabetes such as glycosylated hemoglobin and insulin resistance in obese young people, and reduce the risk of disease.

◆ Huang Qingyuan et al., "Application of Low Oxygen Preconditioning Training in Rapid Advance High Altitude Troops," Chinese Journal of Applied Physiology, February 27, 2011 (3) Method: New recruits who plan to enter the 4300m plateau will undergo low oxygen pre adaptation training using a low oxygen respirator. The training will last for 5 consecutive days, with 1 hour in the morning and 1 hour in the afternoon. The participants will enter the plateau on the 2nd and 6th day after the training, and their acute high-altitude reaction symptoms and physical fitness will be measured. Result: Low oxygen preconditioning training can significantly reduce the incidence of acute altitude sickness; On the second day after training, those who entered the plateau showed a significant decrease in VO2max and PWC170, while those who entered the plateau on the sixth day showed no significant change in VO2max. Conclusion: Low oxygen preconditioning training for 5 days prior to entering high-altitude plateaus can significantly reduce the incidence of acute altitude sickness, and the training effect can be retained for at least 5 days.

Wang Maoye and Lei Zhiping, "Study on the Effects of Intermittent Low Oxygen Training on Aerobic Metabolic Capacity of the Body," Journal of Xi'an Sport University, 2001 (1). The author provides a literature review on the effects of intermittent hypoxia training (IHT) on the respiratory system, circulatory system, endocrine system, and aerobic metabolism enzymes of the body, demonstrating the impact of IHT on the body's aerobic metabolism ability. This provides valuable reference materials for conducting IHT and offers new ideas for the scientific development of exercise training.

Hypoxia Medical J . 1995 , (2) :282321.  The article shows that the IHT training method can enhance the body's compensatory ability, complement high-altitude training, and greatly accelerate the scientific pace of sports training.

J Appl Physiol , 2001 ,90(1) :1052113.  The article studied the effect of IHT on increasing load intensity. At a certain load, due to the displacement of actin and myosin, troponin coupled with myosin is activated, causing muscle contraction; The metabolic system corresponding to muscle contraction is activated. If aerobic metabolism is dominant at this time, anaerobic respiration is automatically inhibited.
