Mirror Muscles and Anterior Dominance

STRENGTH AND FORCE

Are you up for another stock take of your programming? Previously horizontal force production and orientation was a focus, so what say you critique how your program looks in terms of anterior vs posterior weighting of exercises.


I was talking about this with a friend Keith Roberts the other day and his observation was that many athletes are front side (mirror muscle) strong and the posterior chain in many was very weak. How balanced is your program? What is your anterior-posterior force symmetry like?


Sometimes we power up our front side agonist accelerators, with little thought given to our antagonist decelerators. This is remiss. Athletes need the eccentric decelerative strength to arrest the momentum of limbs and/or body. This becomes more important as we power up the prime movers. I often think this is where we need to start our programming, strengthening the antagonist decelerators for injury resistance. The added performance benefit of stronger antagonists could be that they become activated later in a movement meaning greater net agonist activation and enhanced performance gains. Your thoughts?
