241: Michael Camporini and Justin Moore on Learning to Yield in the Gym, Clarifying “Stiffness”, and Understanding Stretch-Shortening Dynamics in Athletic Movement

Our guests today are Justin Moore and Michael Camporini.  Justin is a master instructor and the professional development manager at Parabolic Performance and Rehab.  Justin has been a popular guest on the podcast many times in the past, discussing advanced biomechanical principles in regards to things like breathing, positioning in strength training, and much more. Michael Camporini, "Campo", is a sports physical therapist in Phoenix, AZ, and previously worked with athletes of all different levels and ages with experience as a strength coach at Parabolic.  He has completed internships with Resilient Physical Therapy and IFAST, as well as completing a clinical rotation with Bill Hartman. You may have heard me speak on the drawbacks of doing too much strength and barbell training many times in the past.  Unless we have some ideas of the exact, negative structural changes that happen with excessive barbell lifting strain (and how to reverse them) we might potentially live in a world where heavy weightlifting is some sort of bogey-man we can’t quite define the effects of.  This is important because some athletes need heavier training, while others do not. Recently, Justin Moore (who has a long history of heavy strength training) had a significant knee injury that occurred while demonstrating a skipping exercise (he had injured his knee multiple times in the past), that led him to reach out to Mike Camporini to help him create an intervention program, which led Justin to playing flag football pain free and moving extremely well.  On the podcast today, Justin and Campo talk about the intervention, the issues Justin had from years of too much lifting strain, and how they reclaimed his range of motion and athletic ability.  This podcast goes into many concepts of human function, stretch shortening cycle dynamics, compression versus expansion, defining what “stiffness” really is in context of sport skill, and much more.

Timestamps and Main Points 6:35 Justin’s history of knee injury, and his athletic pursuits that contributed to not being an optimally functional athlete 21:35 How Justin would approach taking compressive lifting away from an individual, and what might warrant the need to avoid bilateral lifting in a program 30:35 What KPI’s in terms of range of motion are Justin and Campo looking at for field based athletes who need to run, jump and change direction 40:55 Thoughts on lifting strategies that produce excess stiffness in an athlete’s system, and how stiffness and stretch-shortening action can be specific to athletic action 52:25 Why being overly “stiff” in a standing vertical jump will negatively impact jump height and resiliency and topics on being “expanded” vs. “compressed” 1:13.45 Some of the tests and corrective strategies that Campo and Justin went through to help fix some of Justin’s faulty mechanics 1:24.35 The use of yielding and oscillating work to help improve the quality of Justin’s movement strategy “Those elements, those compressive training strategies that you do over years to build the strength, to build the muscle.  Those lead to structural changes and certain biases that you need to give time to create any adaptation in the other direction” Moore “When we look as an individual’s situation, we say, what does this person need to reach their goals, where is their endgame, and then we establish things we need to track and we don’t want to lose” Campo “There is a stretch shortening cycle in Olympic lifting or Powerlifting, it is just going to be different compared to throwing a baseball” Campo “How he is behaving and creating these motion deficits is also influencing how he is absorbing energy, or can potentially absorb energy within his elastic tiss...
