RE: What does it take to become a sport's physical ther...
I'm an occupational therapist (OT) not a physical therapist (PT) but work very closely with the PT and our university program was a joint program. When I graduated it was a Bachelor of Medical Rehabilitation with a major in occupational or physiotherapy. Most of the programs are moving to a Master's Degree so it's usually a 5 year program. You can not train to be just a sports physio you are trained to see all diagnoses (cardiac, neuro, respiratory, musculoskeltal injuries etc.) Most of your training will be a hospital setting, sports physiotherapy is a very small area of practice. You will have to be trained in ICU care, post op care, etc, etc. After graduation from your masters program than you can training extra training to become more specialized in an area.
At our university, athletic therapists are trained through the physical education department and I believe it is still a bachelor's degree. When I have spoke with athletic therapists (AT) many of them wish they had done the medical rehabilitation program instead. AT for the most part are outside the medical "team" and paid a fair amount less. They are very specialized in their area but do not have the training do see people with medical issues outside musculoskeletal injuries so are limited to the type of patients they can treat and where they can work. Athletic therapists are not hired here by hospitals. Job opportunities are more difficult to find.
I am in Canada so my knowledge of the USA programs is limited but I do sit on our national board of occupational therapists which has regular meetings with the American associations.
Hope that helps! Kim
