My advice if you are considering this career is to talk to an athletic trainer and find out more about it. You better have a love for sports, and you better have a desire to help others and not mind long hours. If you fit the above, then yes, I would reccomend it. And if I had to do it over, I would do it in a heartbeat becasue I love what I do and I have a passion for it.
The pros would be the fact of how rewarding it is when you see someone accomplish their goals after an injury, and being on the sidelines of sporting events, and being part of the team. The only con some people may have, is the hours. Many times ATC's have to work afternoonrs and evenings since that is the time most practices and games occur. Another may be the travel associated with professional and collegiate athletics.
You should know ahead of time the amount of dedication it takes in college to major in athletic training. You will be assigned to a team, and basically become a part of that team as a student. There you will see what goes on behind the scenes of a practice or game from the pre-event treatments, to the coverage, to the post event treatments. You will be there when the team is there. Additionally is the National Athletic Trainers Association Board of Certification Exam. This exam must be completes in order to become a Certified Athletic Trainer and be able to practice the profession. Also, many states have licensure or state certification in order to practice in that state.
