How to Assess Elastic Asymmetry

No items found.

Wow this resource https://lnkd.in/gEY6AzRi seriously messed up my thinking and took my learning to new levels as my understanding around elastic asymmetry and jump height, velocity, power and work was really challenged. Check it out to see if I have it right?

But let’s back up the bus. What’s going on in that diagram? What has that got to do with assessing elastic asymmetry? Well the signals are of a squat jump (SJ) and a countermovement jump (CMJ), which you can use to provide insight into active force capability from the contractile component (CC) and passive or elastic force capability from the parallel (PEC – mysial tissues) and series elastic components (SEC - tendon).

Single leg comparisons of these jumps can provide you with insights into.
·      Concentric only contractile asymmetry (SJ)
·      Stretch-shorten cycle asymmetry (CMJ)
·      Elastic enhancement asymmetry (CMJ/SJ) otherwise known as an eccentric utilisation ratio

Many athlete’s elastic capability is sub-optimal, especially when returning back from injury. Check out this free resource to sharpen your understanding of elastic asymmetry and so much more.
