The sports medicine field is central in preventing, diagnosing, and treating injuries related to sports/exercise. Some common sports injuries taken care of by sports medicine degree graduates include, but are not limited to, concussions, muscle cramps, ACL sprains, ankle sprains, and shin splints. A bachelor's degree in sports medicine is all about applying scientific knowledge about health toward physical fitness. Some of the courses sports medicine students should expect to take are classes in topics such as exercise science, anatomy, physiology, nutrition and weigh management, sports psychology, sports law, exercise in disease and health, injury and illness assessment, and injury prevention and care. Some popular career options after graduating are: personal trainer, condition and strength coach, sports nutritionist, group exercise, aerobics instructor, sports massage therapist, fitness director, exercise physiologist, etc.  Students can even choose to focus on just one of these areas as they begin to take more advanced courses toward a master's or doctorate, such as in an online PhD in podiatry program. Online sports medicine degrees are offered by community colleges and takes about two years to complete. Students are usually asked to have a "C" average in their sciences classes. The sports medicine degree graduates' goals should be, in the end, to prevent injuries from happening and also to educate those on how to heal them once they do. They are health coaches, regardless of which specific career they end up in.
