Is color acceptable, or rangefinders?
Do you require B&W? Most of the 3200 or 1600 B&W emulsions are true 800 ASA films that need to be pushed or used with specific developers to achieve higher film speeds. Because of that, I've been shooting indoor soccer games for the last year with Fujicolor Superia 1600, which is fine at 1250 ASA for me. If you have to have B&W, you can scan color (sorry APUG) and convert to B&W. That also has the advantage of allowing you to convert different color layers to better distinguish team colors in B&W.
Also, (and I know this wasn't the question) if you have a choice, try a good rangefinder for this if you don't need really long lenses, say over about 90mm, which should be adequate unless you're shooting the length of the court. I've been shooting with rangefinders, the Bessa T and Bessa R3A, using lenses from 40mm to 90mm. The advantages of these particular cameras for sports are 1:1 finders that allow you to frame (and follow the action outside the frame) with both eyes open, a finder that doesn't disappear during the shot (so you know what you got _during_ the exposure), a lot less shutter lag than a typical SLR, and fast focusing (at least on the R3A... I prefocus the T). I haven't used the R8, but my R4s has more lag than my R3 Leica SLR (not to be confused with my Bessa R3A rangefinder). My R4s finder is actually 1:1 with a 50 Summicron, so you might try that on the R8. I don't know the relative magnifications of these finders off the top of my head.
When shooting a game with an SLR, I feel like I'm watching a fraction of the game through a tube. With the 1:1 rangefinders, I can watch the whole game with both eyes open and the frame lines floating in space, cropping to my shot. I can pan over to anticipated action and still watch the whole flow of the game come into frame, then shoot when the time is right. The Bessas also have a manual trigger winder for $160 that allows a steadier grip and at least 2 frames per second, no batteries needed.
If you don't have 35mm rangefinders, consider an older TLR with a sportsfinder built in for some of the same advantages, but a slower film advance, less grain, and a lot more film changing. You might have to hunt for high speed film in 120 too. You never know, Christopher Lloyd might even show up in a tricked-up Delorean and bring you back to the present.
Hope this is useful to someone, and that I haven't gone too far afield.
