Quickly eliminate fatigue; (1) Organizing activities is a good way to eliminate fatigue and promote physical recovery. Coaches and athletes should pay enough attention to it. After strenuous exercise, finishing activities can keep the cardiovascular system and respiratory system at a high level, which is conducive to repaying the oxygen debt owed during exercise. Completing activities can relax muscles and avoid affecting metabolic process due to local circulation disorder. Finishing activities should include jogging, breathing gymnastics and stretching exercises of various muscle groups. Stretching exercise after exercise can eliminate muscle spasm, improve muscle blood circulation, reduce muscle soreness and stiffness, eliminate local fatigue, and also play a good role in preventing sports injuries. (2) Sleep is a good way to eliminate fatigue and restore physical strength. During sleep, the excitement process in the cerebral cortex is reduced, and the catabolism in the body is at the lowest level, while the anabolic process is relatively high, which is conducive to the accumulation of energy in the body. Adult athletes sleep 8-9 hours a day during normal training. During heavy exercise and competition, sleep time should be appropriately extended. Teenagers' sleep time is longer than that of adult athletes, and they must ensure 10 hours of sleep every day. If the training is arranged in the morning and afternoon, take a nap at noon (1.5 ~ 2 hours). (3) Taking a warm bath after warm bath training is the easiest way to eliminate fatigue. Warm water bath can promote blood circulation, regulate blood flow and strengthen metabolism, which is beneficial to the transport of nutrients and the elimination of fatigue substances in the body. Water temperature 42℃ time 10 ~ 15 minutes, no more than 20 minutes. After half an hour of training, you can also take a cold and hot bath. Cold water temperature 15C, hot water temperature 40C. Cold shower 1 min, hot shower for 2 minutes, alternating 3 times. (4) Sauna bath is also called hot air bath or Finnish steam bath. It is produced in China, so it is often used. Sauna is to heat the air with an electric stove in a special cabin to create a high-temperature and dry environment. In addition to calming and congestion of muscles and joint tissues, it can also promote a lot of perspiration. Athletes in wrestling, weightlifting and other events often lose weight before the game. The method of sauna bath is as follows: 1. Stay at 54 ~ 7 1C for 10 ~ 20 minutes. 2. Stay in the environment of 100 ~ 120c for 5 ~ 7 minutes. Repeat 4 ~ 5 times. Take a cold shower 10 ~ 15 seconds at intervals, or take a warm shower for 2.5 ~ 3 minutes. After that, rest in the locker room for 5-7 minutes. (5) Steam margin This is to introduce steam into a special cabin or closed room to create a high temperature and high humidity environment. Its function is similar to sauna, but it is more likely to cause physical fatigue than sauna. The method is as follows: stay at 40.5 ~ 46C for 20 ~ 30 minutes. (6) Massage is an important means to eliminate fatigue. Among them, manual massage is the most popular method for athletes to relieve fatigue, but due to the limitation of manpower, it can not meet the needs. Now various methods have been developed to replace manual massage, such as: 1. Mechanical massage includes massage chair, belt massager, massage bed, roller relaxer and small massage device. 2. Hydraulic massage, such as pulse hydraulic massage machine. 3. Air pressure massage such as air pressure massage clothes, air pressure massage pants, foot air pressure massager, high and low pressure cabin, negative pressure cabin, etc. (7) Physiotherapy uses phototherapy, wax therapy and electrotherapy to act on the part or the whole, which can promote blood circulation, accelerate fatigue elimination and functional recovery, and also has the effect of treating injuries. (8) Using hyperbaric oxygen boat to absorb oxygen, the effect of oxygen absorption at 2 ~ 2.5 standard atmospheric pressure was preliminarily confirmed. Hyperbaric oxygen can increase blood oxygen content, reduce blood carbon dioxide concentration, raise PH value and improve tissue oxygen reserve, and has obvious curative effect on extreme fatigue, muscle soreness, stiffness and acid-base imbalance caused by training. Especially for boxing, wrestling, judo and other athletes who are often hit by the head, it has the effect of relieving headache and dizziness and improving sleep. Negative oxygen ions are also used to eliminate fatigue. Some people observe the effect of negative oxygen ions plus playing music to eliminate fatigue. It is found that it can improve the muscle strength of back muscles, improve cardiopulmonary function and increase hemoglobin concentration. (9) The consumption of various nutrients increases during nutritional exercise, and timely supplementation after exercise is helpful to eliminate fatigue and restore physical strength. Sugar, vitamin C, vitamin B, water, etc. Should be fully supplemented. (10) Drugs In order to eliminate fatigue as soon as possible, some drugs can be used appropriately. Such as Huang Mao, Du Wujia and Shen Sanqi. All of them have the functions of regulating central nervous system, dilating coronary artery, invigorating qi and strengthening tendons, and have a certain effect on eliminating fatigue. Royal jelly, ginseng and pilose antler have good effects of nourishing blood and invigorating qi. (XI) Psychological recovery is to eliminate fatigue by regulating the function of cerebral cortex. Qigong, ideas, relaxation exercises, etc. They all belong to this kind of timekeeper, timekeeper, timekeeper, single wing drop tester, Sony carbon ribbon magnetic stirrer image measuring instrument, ultraviolet lamp weather-resistant test box, rigid slide wire, outdoor photo machine, orifice plate temperature sensor, pressure gauge, compressive strength ring pressure gauge, LED electronic display screen, Omron thermostat, switch rain-proof test box, explosion-proof safety cabinet, hollow coil dielectric loss tester, pressure transmitter and ammeter.
