Sprinters are muscular and usually a little on the bulky side.

Muscle is what makes you move, and the more of it you have, the more powerful it is. If your muscles are developed properly, and you train to develop proper technique and muscle memory, you can be fast and powerful. I know my jab feels very fast compared to a lot of boxers that I've seen. And with a single quick jab, I can make my 70 lb. bag go flying like nobody's business.

I'm not a boxer as much as a combat sport enthusiast and I haven't sparred with a live opponent in a long time so I'm no expert in this area. But if you want to see some real speed and power from a "heavyweight", check out somebody like Vitor Belfort from the UFC.... unbelievable handspeed and knock out power from a guy that weighs around 225.
