What about using this as an other option for building Quads? It looks effective since sprinters have hugh legs. It utilizes fast twitch 2B`s. I take it that this would also burns a lot of glycogen that would have to be replaced soon after.

Yep, right on! Sprinting is very anaerobic. It actually hits the hams and calves harder than glutes and quads, but definitely awesome for legs. Try substituting sprinting for leg day as a shock! Walk-back sprints work great - sprint all out for 15 seconds, then walk back to your starting line (about 45 seconds) and do that 5 times. Work up one more each time.
Since that type of exercise is at such a high intensity, you're right, it burns mostly glycogen for fuel. So, after you're done, you'd probably want to eat some high GI carbs or a Post workout shake similar to after a weight training workout [img]/forum/images/graemlins/cool.gif[/img]
