Description
More show notes at https://www.just-fly-sports.com/podcast-290/ Today’s show is with coach and inventor Adarian Barr.  Adarian has spent decades coaching in the college and private sector, and currently consults with a variety of coaches in multiple sports.  Adarian has been a guest on this podcast many times, and has a unique, connected, and incredibly detailed perspective on the drivers of human movement. One piece of movement that we haven’t made a theme for this show yet is getting into rotational, “tumbling” actions of joints.  When we think of “rotational force” in movement, we often just think of “twisting in the weight room”, or training “transverse plane”.  When it comes to “front to back” movements, it is common to simply think in terms of perpendicular forces in terms of movement.  With perpendicular actions, think of a coach telling an athlete to stab or drive their shin straight down to the ground in acceleration, for example, or any coaching cue that has to do with “pushing the ground away”. In any sport movement, however, the tumbling, or “pitching” motion of body segments (such as the shins) are going to be massively important when it comes to speed.  It’s easy to load hundreds of pounds on a calf raise (a perpendicular force) but to be fast, think sprinting and throwing, rotation is inevitable, so it pays to be familiar with it to make better sense of movement coaching, and building better drills and constraints for athletes. On today’s episode, Adarian will speak on perpendicular versus rotational aspects of movement, and what it means for exercises, especially common sprint drills.  He’ll talk about the actions of the various lever systems in the body, and how to optimize the way we load these levers for a variety of movements (with sprinting as the primary example) as we use rotation to move with speed.  Adarian will talk about the ideas of “big and small wheels” as well as how not to make the wheel action of limbs a square one, as well as other interesting universal movement concepts.
