From shooting a basketball to scoring a goal sports play a major role in many teens’ lives. People's teenage years are also the best time to play and participate in sporting activities. Schools make sports more competitive as teens enjoy the thrill of winning. But when teens start thinking about pursuing sporting careers, certain sports would result in training sessions daily and a higher intensity level. Teens account for an estimated 2 million injuries and 500,000 doctor visits each year. Injuries can affect anyone and there is no single sport that is specifically to blame for the increase in sport-related injuries however, sports are played to improve fitness, learn new skills, and to make friends. In conclusion, with the increased competition and intensity levels in today’s sports, injuries are rising immensely. We must be aware of prevention methods so teens could continue to play the sports they love and not get injured in the process.
