Recently, some college games canceled the women’s 3000m and men’s 5000m projects, yet the Guangzhou Marathon long-distance run has just been held. Is it necessary to strongly promote the sport of long-distance running? What are the effects of cancelling long-distance running on students’ body? How should we deal with some accidents such as muscle strains during long-distance running? Let’s listen to the opinions of orthopedic experts. Long-distance running is good for the body, and it is not advisable to cancel the long-distance running program in colleges and universities. Director Xu Hongzhang said, long-distance running is a very beneficial sports, it is the minimum requirements for equipment, venues and other facilities, is the exercise of young people’s heart and lung function, enhance endurance, improve lung capacity, sharpen the quality of will one of the best methods, its effect is difficult to compare with other activities. It is also a better way to enhance the physical fitness of young people as soon as possible under the current conditions in China. The cancellation of long-distance running in colleges and universities will have a great impact on the improvement of college students’ physical fitness in the long run. Long-distance running has many benefits to the body: 1. it can improve the function of the respiratory system, make the lung function stronger and increase the lung capacity. 2, can improve the cardiovascular system function, promote blood circulation, lower blood lipids and cholesterol, is conducive to weight control. 3, conducive to disease prevention and treatment. It plays a cleansing role for harmful substances in the excretory system. 4, conducive to a relaxed mood, happy spirit, very useful for relieving study stress. 5, eliminate the fatigue of mental work, improve the ability to resist stress, is conducive to training students to overcome difficulties, sharpening the tenacity of hard work and endurance. 6.Increase the strength of muscles. Increase the flexibility of joints and strengthen bones. Therefore, long-distance running can promote the healthy and harmonious development of students in all aspects, such as physical, psychological and social adaptability. Long-distance running is regarded as “the king of aerobic metabolic exercise”, the amount of exercise is easy to control, suitable for people of different ages, genders and physical conditions, and in the process of running can regulate the physiological functions of the human body and the ataxic coordination of organs. The harm of canceling long-distance running: it is not conducive to the popularization of long-distance running, to the overall enhancement of students’ physical fitness, to the cultivation of students to overcome difficulties, to refine the hard-working will. 400-meter obstacle course, tornado, long braid, etc. Although the fun items such as “400m obstacle course”, “tornado” and “braid long braid” increase the fun, the exercise time is short and the whole body moving parts are limited, the benefits to students’ physical and mental health are not as comprehensive as long-distance running, they can improve the explosive power and strength of students’ organism. Life is a marathon, long-distance running should become a national sport Recently, the Guangzhou Marathon has just been held, the marathon fully exposed the problem of young people’s physique is not as good as the elderly, in various medical stations, falls, sprains, fainting are mostly young adults aged 20 to 35. Some athletes’ poor physical fitness is also surprising: “only after 10 kilometers of running, a large number of young people were helped off the field”, and there were even cases of sudden death. For the marathon, Xu Hongzhang, director of the sport, expressed great support, here Xu Hongzhang director quoted a proverb “life is a marathon”, the long life is compared to a marathon, so we can see how hard the marathon is a thing. To run such a long distance, you need to endure both physical and mental pain, and to win the race, you must have excellent physical and mental quality. Therefore the marathon race is a sport that gets exercise from the whole body and mind. The Guangzhou Marathon long-distance running activity is of great significance: to promote the good sport of long-distance running, to promote Guangzhou, to encourage outdoor sports, to encourage a healthy physical and mental lifestyle, to focus on sports to focus on health. We should not only carry forward and actively participate in it, but also organize it frequently to form the atmosphere of long-distance running or marathon running among all people. At the same time, Director Xu Hongzhang also reminded to the usual people to participate in the marathon, pay attention to good preparation. Generally to prepare for six months, six months during the exercise is slowly increasing. For the phenomenon of sudden death in the marathon, some experts have done monitoring, marathon inside an average of 50,000 people have 1 death. Theoretically, if the more adequate preparation, this accident rate will be reduced. So before the long run, be sure to do a good job of preparation. The public who usually lack exercise, should pay attention to the amount of strength. At the same time, the public must strengthen the awareness of exercise, enhance their physical fitness, and must strengthen the exercise in ordinary life. Long-distance running how to prevent muscle strain and muscle strain emergency treatment For long-distance running, Xu Hongzhang director revealed, generally do not advocate at once to run more than 3000 meters, the first jogging 1600 meters – 2000 meters is appropriate, with the body’s gradual adaptation, and then gradually increase to more than 3000 meters, it is advisable to jog first, to long-distance running ability has improved significantly, only gradually accelerate the speed of running. For long-distance running may encounter muscle strains, director Xu Hongzhang gave us some advice. Prevention of muscle strains: To avoid muscle strains during long-distance running, the following points should be noted: First, avoid wearing uneven socks, too small and too tight or hard-soled shoes. Second, try to choose a flat field for long-distance running. Third, do enough preparation activities before long-distance running. For example, joints, stretching ligaments of hand exercises, the first 400 meters of relaxed running, 400 meters after the acceleration can be run. Generally speaking, the warm-up exercise should be about 10-20 minutes, through the relaxation of muscle, pulling movement, light activity “remind” muscle immediately to carry out a large amount of activity. Fourth, long-distance running action should be correct, avoid doing some large amplitude jumping and vacating action, so as not to land unstable caused by joint and muscle sprains. To emphasize the foot landing technology to be correct, long run. To keep the body activities coordinated and smooth. With the forefoot or the forefoot outside the landing, and then transition to the full-footed landing. This can reduce joint and muscle damage. And can save energy. Improve the speed. Fifth, the amount of exercise should be gradual. Start jogging 1600 meters – 2000 meters is appropriate, with the body’s gradual adaptation, and then gradually increase to 3000 meters or more, it is advisable to jog first, to be a significant increase in long-distance running ability, only gradually accelerate the speed of running. Sixth, strengthen local protection. For example, wear protective gear to strengthen the local tissue warmth and protection. If the intensity of exercise or a longer period of time without exercise can be used leg guards, ankle protection and elastic bandages for simple protection. Seventh, appropriate supplemental energy and electrolytes before exercise. For example, eat something and drink some sports drinks. Eighth, after exercise should pay attention to finishing activities, such as jogging or walking slowly for a while, do a few deep breathing, etc., so that the body gradually calm down. According to the reaction of the body after long-distance running to increase or decrease the amount of load. Emergency treatment of muscle strain: When a muscle strain occurs, how should we deal with it urgently? There are 4 basic treatment measures that need to be paid attention to in the acute stage of muscle strain. Rest: that is, when a muscle strain occurs during exercise, the first thing to do is to stop the exercise and strengthen the rest. Ice: The best way to deal with a muscle strain in an emergency while exercising is to apply ice, because if there is bleeding when the muscle is injured, using ice can make the blood vessels constrict to reduce bleeding and reduce tissue edema. Compression: In addition to ice, the method of local compression can also reduce local bleeding and edema. Elevation: During recuperation, care should be taken to elevate the injured area so as to reduce local swelling. Muscle strain care precautions: try to brake and rest in the early stage, and it is advisable to apply ice to apply pressure and improve swelling in the early stage. After the acute period, the general muscle strain, available leg protection, ankle protection and elastic bandage for simple treatment, etc.. You can also apply some blood-activating internal and external drugs or local physiotherapy to reduce swelling and promote healing, and you can do some jogging without pain, and then participate in exercises after basic healing, but in a gradual manner. Finally, Director Xu Hongzhang introduced us to the small needle knife technique for sports strain injury. The small needle knife technique is a treatment method combining Chinese and Western medicine, which is formed on the basis of the incisional surgery method combined with the acupuncture method. It is a very good method for treating sports strain injury, which can effectively enter the local sports strain injury, to release the adhesions, hard knots, contractures and tensions between the muscle ligaments and fascia caused by the strain injury, in order to achieve a more thorough treatment effect. The advantage of small needle knife therapy is that the treatment process is simple and not restricted by any environment or conditions. The incision is small, no sutures are needed, the damage to human tissue is also small, and it is not easy to cause infection, no adverse reactions, and the patient has no obvious pain and fear, no need to rest after the operation, the treatment time is short, the course of treatment is short, and the patient is easy to accept. Therefore, the treatment of sports strain injury by small needle knife is generally not dangerous. After the small needle knife surgery treatment generally do not need to make special treatment, but after the treatment may have local swelling and pain, it is recommended to rest 3-5 days, if the pain is obvious, you can also temporarily take some oral anti-inflammatory and analgesic drugs.
