Athletic training is an allied health care profession recognized by the American Medical Association (AMA) that “encompasses the prevention, examination, diagnosis, treatment, and rehabilitation of emergent, acute, or chronic injuries and medical conditions.”
There are five areas of athletic training listed in the seventh edition (2015) of the Athletic Training Practice Analysis: injury and illness prevention, wellness promotion, examination, assessment, diagnosis, immediate and emergency care, therapeutic intervention, and healthcare administration and professional responsibility.
Athletic trainers (ATs) generally work in places like health clinics, secondary schools, colleges and universities, professional sports programs, and other athletic health care settings, usually operating “under the direction of, or in collaboration with, a physician.”
