My daughter isn't playing basketball thus year (senior year) but she did from 7th through 11th grade. She had to get a physical every year. Since she has been in good health all her life , the physicals have been really basic. They listen to her heart and breathing, check her reflexes that sort of thing. The entire exam takes about 10 minutes tops.
It's way more simple and less awkward than a regular physical. Basically they check your heart beat and your ears, etc. and then they tell you to touch your toes and they feel your spine, and check your breathing:)
