i'm at swansea in wales, which is pretty good for sport science. But i believe the best in the UK for sport science is Banga university, also in wales. I have to also say... other than the teaching i think you'd be gutted you went there, not a lot of people, and is in north wales which speaks for itself (no offense to anyone). It would really depend on what course you wanted to do. Find the uni rankings for that course. Also it depends on whether your course is specifically dependant for your job or not, and whether you just want the degree from the top overall universities, or one (which may not be overall considered a great uni) that is good for your course. Lots of options really
