Information on Kinesiology and More for USNA?!

I have recently gained interest in attending a US service academy and being stuck between USNA and USMA, I believe USMA would be a better fit because it has a major I am interested in, Kinesiology, unlike the USNA. Just for some extra information, I am a female and a current junior.
I did have a few questions, and I apologize in advance if they seem idiotic in any way because again, I have only done about a day of research thus far.
First of all, how would a kinesiology major serve in the army after achieving a bachelors degree? The reason I am choosing kinesiology is because I have always wanted to be a physical therapist and this dream still lies with me today. If not physical therapy, sports medicine and exercise psychology also interest me. My question is though, with this career path, how would I serve in the army as an officer?
My second question is that I do have a greater longing towards the USNA in terms of location and other aspects as well. I know there is not Kinesiology major offered there but are there any somewhat related majors?

I would really appreciate all input as I do feel very lost as of now and research has been coming to a bit of a halt. Thank you very much.

At the service academies, what you major in is not necessarily related to your service selection. That is, an English major could be an aviator as easily as a physics major. If your dream is to be a physical therapist (or similar), USNA is probably not the right place for you. Each year, 10-12 Mids choose medical corps after graduation - but that’s medical school for an MD, not for PT.

I agree that serviceacademyforums.com is the best source of information on all the service academies.
