This page came about as a reaction to the observed concept of pinching back the shoulder blades. This is now commonly referred to as scapular loading (or scapula loading). However, there may be other factors to consider. WebBall is not going to tell anyone that scapular loading is wrong because the evidence we've seen clearly demonstrates that torque and momentum and loading up are key components of optimizing velocity. But you should consider all the facts. A note about language: this article tries to avoid medical-speak as much as possible. WebBall Team Players who want to know details about the glenohumeral joint and the glenoid fossa in particular can click on the image link, and anyone can purchase the Sport Injuries software and delve into this for themselves.
