Student Exchange Programs

im currently studying sports and exercise science in australia and i would love to go over and study in america for 6 months..
I was just wondering on how different it is from here to over there for uni life and living on college there?
What do you do for fun, spare time, play sports??
Yeah i pretty much just want to know the life of uni students that live on college over there.

And what universities are over there that study sport and exercise science or something along those lines

Thanks
