Hi Sally

I also had the same problem. I was using the Nikon D60 at the time and was trying to take photos of Judo in action. I ended up using my 50mm 1.4 but I suppose you are limited by lighting (fluro lights) and white walls, and white judo outfits. It is a challenge. I also had increased my ISO to 1600. I also used flash but felt bad "flashing" everyone all of the time.
