Text 3 Injuries can happen at any time, any place. When they do occur everyone likes to get the best treatment to help them heal quickly and properly. For athletes, the need to receive proper medical care is crucial in order for them to continue their sports careers. Athletes depend on the knowledge of doctors who are specially trained in sports medicine, which is a field of medicine that has grown rapidly since 1950s. Sports medicine is more than just the treatment of injuries. It is also concerned with the prevention of injuries, the maintaining of a proper diet, the creation of individual exercise programs for an athlete and the mental preparation of the athlete. In general, sports medicine is relevant to all aspects of monitoring athletes while they are in training. The field of sports medicine includes nutrition, surgery, physical therapy, research, and orthopedics, which is the correction or cure of disease or deformities of bones, joints and muscles. The doctors who specialize in sports medicine are called sports traumatologists. These experts’ specialize in the care of injuries to the musculoskeletal system. They do physical examination, diagnose injuries, and refer patients to surgeons if necessary. Although people have been interested in sports medicine for many years, it actually became more specialized after World War Ⅱ, with great developments in the 1960s and 1970s. The modem idea of complete care for the athlete emerged from the widespread surge in sports participation over this time period. The field of sports medicine is very broad because there are so many types of sports injuries and because each individual athlete’s body is different-their make-up, build, immune system, etc. Because of this, virtually every injury is treated in a different way. As injuries continue to occur and the sports medicine field grows, recovery methods are becoming more advanced. Two of the more modern methods of treatment are the hyperbaric chamber and magnetic resonance imaging. A hyperbaric chamber is a cylindrical steel tube into which a person can enter. Inside the chamber, the athlete is exposed to high levels of oxygen. This promotes oxygenation of the blood and speeds recovery time. Use of magnetic resonance imaging (MRI) in medicine began in the early 1980s. MRI presents a hazard-free way to get images of thin slices of the body and a reliable method of detecting injuries. It is a superior imaging technique because it doesn’t use radiation or need any special dyes. MRI uses magnets to concentrate and focus on small areas of the body, which produces detailed images. Besides being used to diagnose sports injuries, MRI is capable of producing high-contrast pictures of the brain, heart, liver, kidneys and can detect things such as tumors. It is quite possible that with the increased interest in sports, the field of sports medicine will become even more specialized. Sports medicine continues to grow and take care of the needs of athletes from the professional playing in front of a stadium full of people to the person working out at their local health club. MRI can be used for

A. diagnosing patients who are not athletes.
B. promoting oxygenation of the blood.
