Effects of Low Pressure Hypoxia on Oxidation - Antioxidant System of Player

摘要

Purpose: To study the effect of hypobaric hypoxia on the oxidative-antioxidant system of volleyball players, and to provide a safe and reliable clinical treatment for cardiovascular disease. Method: Eight volleyball athletes trained on low altitude and low oxygen in a plateau on May 12, 2017 were listed as observation group, and 20 athletes trained in normothermic normoxia were selected. (P <0.05). The levels of superoxide dismutase (SOD) and catalase (CAT) in the brain tissue of the two groups were significantly higher than those in the control group (P <0.05), and the levels of mitochondrial malondialdehyde (MDA) And myocardial mitochondrial free Ca~(2 +) levels. Result: The levels of SOD and CAT in the observation group were lower than those in the control group (P <0.05), and the level of SOD and CAT in the observation group was the highest (P <0.05). The expression of Cygb in the observation group was higher than that in the control group. The level of Cygb in the observation group was higher than that in the control group (P <0.05, t = 2.8676). The myocardial mitochondrial free Ca2 + level in the observation group was lower than that in the control group, P < 0.05, t = 5.8190. Conclusion: Volleyball player's oxidation-oxidation system is related to the generation of oxygen free radicals. It can be judged by monitoring the parameters such as SOD, CAT, Cygb, MDA, ATP, Ca~(2 +) and other indicators in the brain tissue during the daily life signs of athletes. According to the principle of relevance, take CIHH for treatment.
