1.Why is the flyer’s Achilles tendon difficult to recover? Liu Xiang did the Achilles tendon reconstruction surgery in the United States and insisted on the difficult rehabilitation training, but his Achilles tendon part damage is a long-term accumulation of results, 110m hurdles for this part of the Achilles tendon requirements are very high. Achilles tendon reconstruction for ordinary people may meet the general life, or simple fitness recreation project, but for Liu Xiang competitive sports, high intensity exercise for the Achilles tendon this part of the challenge is very big. Injury is the biggest enemy on the road to success for athletes, but also plagued by many athletes. 2, sports enthusiasts do not pursue the limits of sports-loving young friends always want to go farther in the road of sports, but also very longing to break through the feeling of self-improvement, through hard work can indeed break through many physical limits, but when some limits are broken through will damage our limbs, go to the limit when everyone is very vulnerable. According to the concept of exercise physiology, everyone’s physiological conditions, and you match the sport is really different, to pay close attention to their own state, to be treated differently, and in the training process must be gradually and reasonably arrange their own exercise program, to put their own mind at peace, to find the most suitable for their role, not everyone has to rush to the first, you just need to be able to Mobilization of body functions to obtain health, is the most ideal state. 3, exercise is not to play with life real fitness method is not to say that every day desperately to practice, say I am very hard every day, a day can have 7, 8 hours in the gym, this is absolutely a very risky silly practice. The right way to work out must be a combination of work and rest, the amount of exercise is strictly gradual. There are some people who will have acute joint swelling and muscle congestion after practicing in the gym, which is practicing too much. Usually do not exercise, the occasional crazy climbing a mountain, but also the damage to the body. Without the usual accumulation, the body muscle energy has no basis, is the cause of injury. Work is good, it must be the first tool, many people will buy professional sports equipment, the movement has a certain protective effect. But the most joint equipment is the human body’s bones and muscle soft tissue! 4, exercise preferred to persistent aerobic aerobic exercise can not only exercise the coordination of the limbs, exercise the ability of each of your movement, strength, flexibility, etc., but also to strengthen the cardiorespiratory function, which is the best for fitness. Aerobic exercise is the first choice: jogging, swimming, flat even cycling, these exercises for joint damage is very small, but the exercise is very significant, as long as the weather conditions and site conditions allow, if you can participate in aerobic activities four to five times a week, each time the time in 30 minutes to 40 minutes or so, the total time control in about two hours, it basically reached the general population fitness The purpose. Aerobic exercise requires a long-term persistence, not a certain time of surprise training. 5, minor injuries do not necessarily go to the hospital just an inadvertent action led to joint discomfort, sprains lead to soreness, these feelings, most of them do not cause joint swelling, pain, limited movement. In this case, it is not necessary to go to the hospital, you can go through some simple treatment, such as the necessary rest, conditioning and recuperation. 6, pain caused by dysfunction, to seek medical attention if the injury after the discovery of the joint or limb parts of the swelling, pain, these symptoms affect the normal life, learning and work, and even the emergence of obvious joint dysfunction, such as ankle swelling, can not walk, the knee, ankle joint there is obvious pain, the joint can no longer be used normally. This time can need to go to a professional doctor to do some early examination, the purpose is to early detection of disease signals. 7, old injuries will become your weak link broken foot, ankle sprain history, will become an old injury. Play ball when the power has suffered a back injury, a power will flash the back. This kind of injury to say a little more elegantly called the accumulation of strain, is your weak link. After the injury, the body will go through a bleeding, swelling and then slowly swelling, inflammation dissipation and then improve the process, after the process is well, only means that this time the injury receded, but does not mean that the weak link does not exist, the weak link of the injury will always become your body’s weak link. For example, there are many friends, after the ankle sprain actually have ligament damage, ligament damage is not properly healed, after each movement occurs repeatedly joint dislocation, crooked foot and sprain, will seriously affect the health of the joint, need medical means. 8, especially to pay attention to the repeated accumulation of sports injuries Liu Xiang recalled in microblogging, in front of the achievements, he heard all the praise, he did not pay attention to his foot injury, the pursuit of speed, and constantly increase the training load to make the foot injury from light to heavy. For ordinary people, sports injuries if you do not pay attention to, or did not master the scientific training methods, the pursuit of the so-called breakthrough, then instead brought about by the damage to your body.
