Humans organize themselves in 2 ways with regard to gravity & this plays an important role in movement and technique. 

If COG passes ⊥ through the hip joint, it would be difficult to move. 

We always need balance consolation, some prefer to do this by bringing COG to the front & others by bringing it back!

The posterior muscle chain is more active in athletes whose COG is in front of the hip joint

They have a higher starting position & the shoulders/head will initiate movement while the pelvis tilted backwards in the preperation phase.

Example:

BLAKE SNELL & RANDY JOHNSON = PM muscle Chain Athletes 

* Generates power from bounce (leg extension – back muscle chain)

* Supinator

* Plyometric

* Muscle lengthens

* Energy recovery

* Catabolic

* Needs more recovery.
