If you're shooting digitally, you can boost up your iso-levels; gaining more light-sensitivity.
The downside to this is that you'll get more and more digital noise as well.
Another way is to widen up your diaphragma (not sure if i spell it here correctly, it is the iris-like thing inside a lens). Close it you'll get razorsharp pictures all the way through, but you'll need a heck of a lot of light to do so.
Open it wide up you don't need alot of light, but you'll also have a huge loss of DOF.
Finally there is always the option to get a lens that is as light-sensitive as possible.
I'm fairly new to photographing moving objects as well though; my subjects (textures, objects) usually don't move that much.
A tripod or a steady spot to lean on is sufficient in that cases.
There are many good photography forums out there for if you really want to get to the bottom of this.
I can't name one though; the ones I visit are all in Dutch
