There are many schools that require Exercise Physiology, although the majority do not.
UM Flint requires, as per someone else's post.
Others I'm looking at that require it are Boston U, MGH, and Ohio State.
UNC requires it AND also requires it to be COMPLETED before the end of the school term in which you submit your application. Which makes it more challenging, and doesn't seem to make sense anyway as their program does not start until Fall. (Leaving Spring and Summer available to wrap up any pre-reqs.)
UNC and OSU both suggested USSA (United States Sports Academy) but this seems to cost a lot of money.
University of New Mexico has offered it online before. And for just one class they do not charge out-of-state tuition, so it's very cheap!

I contacted the prof who said it might be available this Fall (depending on interest) and to contact him in August.
So maybe folks needing the class can contact him now so he knows there is a need for the course?
There is an e-mail for the prof in the brochure posted above.
