Can someone please explain to me what plyometric extension is in relation to kiesiology?
My kinesology teacher states that any time your body is bearing weight on one leg that you are in plyometric extension with that leg. She really doesn’t give a good explanation of what it is, even thought as a class we have asked many times.
So for example in the upward phase of the lunge she says your lead leg is in hip extension while your back leg (on the floor) is in plyometric extension. I have googled and searched on here for a defention. I am just confused.
Thanks.

Hmmm. I am self taught in Kinesiology so I can only speculate here, but to me the joint action at the hip for the lead leg during the lunge would be hip extension. It’s not the lead leg that’s in hip extension, it’s the hip joint (at the side of the lead leg) that is undergoing hip extension.
When she states that the rear leg is in plyometric extension, perhaps she is referring to the stored energy that the hip flexor muscles on the rear leg side would possess since they would be in a stretched position and would have the potential to lend themselves toward a powerful, explosive contraction if called upon. However, this joint action that the rear leg would execute would be hip flexion.
