More often than not, the people you see hanging off pull-up and dip bars have not earned the rights to perform resisted variations of either movements. These individuals are likely candidates of upper extremity issues in the near future.
Why is this?
Insufficient scapular control is a typical culprit and wreaks havoc on the glenohumeral (shoulder) joint. The ability to move the shoulder through all of it's possible ranges of motion also elicits the potential for injury when individuals put themselves in vulnerable positions.
Shoulder Controlled Articular Rotations (CARs) can help you assess what limitations you have with shoulder mobility.
Just like the hip and ankle CARs we've previously touched on, shoulder CARs are a great way to maintain the current ranges of motion you have. When bringing joints through their end-ranges of motion under controlled tension, joint mechanorceptors receive sensory feedback. This sensory input on a consistent basis allows us to preserve the mobility that we have obtained. In folks with extreme range of motion limitations, constant CARs practice can even help improve the restrictions at hand. Moral of the story: do you CARs every damn day.
In the coming weeks, I'm going to dive deeper into the shoulder complex and supply you with drills that can help improve the way you feel and move. Dysfunction dictates discomfort; even though every case of injury is different, if we can improve the way we move and control joints the better chance we have of staying pain-free.
