Today’s episode brings back Rick Franzblau, assistant AD for Olympic Sports Performance at Clemson University.  In his two decades in athletic performance, Rick has worked with a wide variety of sports, as well as gained an incredible amount of knowledge in both the technology, and biomechanics ends of the coaching spectrum.  Rick, as with many other biomechanics topic guests on this podcast, has been a mentee of Bill Hartman, and has appeared previously on episode 94, talking about force/velocity metrics in sprinting and lifting.

There is a lot of time spent, talking about an “optimal technique” for various sport skills (such as sprinting).  We also tend to look for “optimal lifts” or exercises for athletes, as well as optimal drills athletes are supposed to perform with “perfect form” to attain an ideal technique.

What the mentality described in the above paragraph doesn’t consider is that athletes come in different shapes and structures, which cause what is optimal to differ.  Wide ISA athletes, for example, are fantastic at short bursts of compression, have lower centers of mass, and can manage frontside sprint mechanics relatively easily.  On the other hand, narrow ISA individuals use longer ranges of motion to distribute force, have a higher center of mass, rotate more easily, and can use backside running mechanics better than wide-ISA’s.  Additionally, there is a spectrum of these athletic structures, and not simply 2 solid types.

On today’s show, Rick goes into detail on the impact and role of compression in human movement and performance training, the strengths and weaknesses of the narrow vs. wide ISA archetypes, what differences show up in locomotion and sprint training, as well as how he approaches strength training for the spectrum of wide to narrow individuals.  Today’s show reminds us (thankfully) that there is no magic-bullet for all athletes, and helps us with the over-arching principles that can guide training for different populations to reach their highest potential.
