Feedback and GMP of Squat

I will be making video explaining Feedback (internal and external) for a squat movement and General Motor Program. The video is not necessarily needed to write a short paper. Are you able to explain the below areas below of the squat? Do you need more information.

1. Feedback for a specific skill

-Knowledge of Results
-Knowledge of Performance
-Proprioception

2. General Motor Program choose one GMP and show it in action during two different motor skills. How do the following parameters change:

-Muscles used (will be very similar)
-Order of activation of muscles and de-activation
-Force of muscle contraction
-Duration of muscle contraction

with at least six scholarly APA references and documentation. The reference page is in addition to the five-page executive summary.
