Ok...I've been thinking about this video a lot since I first watched it. I'm not a world class sprinter, and never was, but I do know my traps from my delts...so I'm going to go out on a limb and assume a level playing field of biomechanical knowledge for now.
This guy has some sick jumps. No question. But I don't think I agree with his logic. The part of the video where he's saying, "Sprinting is just this," and he's hopping his fingers across the box, that's not really true. When you're sprinting you want to stay low and use as little up and down movement as possible. Any movement up and down eats away at seconds you could be moving forward; it takes less space and more time to move up and down. So when you're sprinting it's like from one angle you're in a static contraction (crouched position) and from another angle your legs are pumping through that plane.
So my question is, why not train plyo/strength going forward in addtion to up? Especially if you're only going up for mental reasons?
Have any of you ever sprinted with a sled or a parachute? Or heavy clothing, hiking gear, etc? Notice how fast you feel when you take it off? It's like stepping off a trampoline and still feeling like you're jumping.
