I study in sport science. what field can i involve beside sport. i mean in medice field?

Follow your dream: I've known olympic athletes, fitness specialists, kinesiologists, and a host of other folks from the elite sports community who've gone on to become unusually interesting and colorful physicians. If you really enjoy science and are willing to make huge sacrifices in your personal life to help others, medicine may be for you.

Wide range: You could consider going into physical therapy, physical medicine & rehabilitation, orthopedics, occupational therapy. You could consider medical school, graduate school for physical/occupational therapy, advanced degrees in physiology or other science fields to go into research or an educational position.
