I actually went to undergrad for athletic training, got my degree and passed my national exam. However, after 4 years of hard work I realized that the long, inconsistent hours, little pay, and time away from family just was not worth it for me. Now granted, I did learn a great deal about rehabilitation, patient interaction, gaining patient trust, forming a rapport with the patients, and obtaining a great deal of confidence in my ability to be a health care provider. I just knew I wanted a bit more.
Taking the pre-med courses simultaneously is possible (I had a few classmates who did it), but your time is very limited due to the great commitment to clinical work, travel time, and your AT classes. Not to mention trying to find time in there for yourself and friends.
I just finished all my pre-med classes in a post-bacc after graduation (took me 3 years due to working full time and supporting wife in law school), but it's been 100% worth it. I just got my MCAT scores back and expect to apply to pod school for 2010. So if sports medicine is something you want to do, then I suggest shadowing an athletic trainer for sometime to really get a feel for what the profession is like. FYI, we had 20 people my first day freshmen year and of those 20, only 2 people (including myself) made it all 4 years. Others came and went a long the way, so we ended up with a total of 7 in my class. But 2 surviving out of 20 is NOT a good number. Especially considering I don't practice and am preparing for another field.
This ended up being longer than expected, so PM me if you have any particular questions.
Hope this helps! 🙂
