“Misery acquaints a man with strange bedfellows.”
A while back, the site Straight to the Bar featured this clip of Scott Jackson bustin’ off some phenomenal, Parkour-inspired moves. Seeing this clip again recently got me to thinking about a few of things. First, I wonder if each individual is limited by some inherent power/bodyweight ratio? Actually, I know a mechanical limit exists — structurally, our bones, ligaments, tendons and musculature can only handle so much stress — I’m referring here to practical limits. And how would one go about figuring that limitation? Would we even want, in a psychological sense, to know that limitation? And second, this got me to thinking about the intersection of power generation and MetCon work; specifically, exercise selection. And not just exercise selection alone, but exercise selection with an eye toward targeting an identified energy system. Most sporting endeavors require a highly tuned and efficient combination of energy systems to “fuel” the participant through the event. Identifying and training these systems properly is, or should be, the lone goal of MetCon work. You might want to read this post first, if you haven’t already. Then come back here and check out some of Scott’s unreal moves. As you watch, ask yourself (1) what energy systems does Scott rely on mostly, and (2) how would you go about training him without diminishing, in any way, his form, technique and skill? Just a few things to ponder while you watch:
Another thought that bubbled-up in my mind while watching this clip is just how “springy” Scott is. What do I mean by that? Well, there’s a subtle, but huge, difference between the body’s levers acting as a spring, as those same levers acting in the manner of a piston. Good sprinters quickly transition from the “piston” action of the start, to the “spring” action of the stride; good jumpers come off the floor like a spring, jumpers who need work “piston” themselves up and airborne. But more on that in a later post.
