Rotator Cuff Training
Before we can understand the benefits of training the rotator cuff, it would be helpful to review which muscles we are actually talking about. The rotator cuff is composed of four muscles. These muscles are the subscapularis, teres minor, supraspinatus and infraspinatus. These muscles are responsible for internal rotation, external rotation and abduction of the shoulder. The rotator cuff also stabilizes the humerus in the glenohumeral joint (shoulder).
One of the main reasons that these muscles are prone to tears and overuse is that the blood supply is low. Blood carries nutrients which help muscles recover and rebuild. If the rotator cuff muscles are never trained, simple tasks such as painting could result in injury. To prevent and possibly avoid rotator cuff injuries, the muscles should be trained at least once per week.
Some of the benefits of this type of training include:
-Reduction in impingement syndrome
-Improving the stability of the shoulder joint
-Prevention from conditions like “frozen shoulder”
-Improving the mobility of the shoulder and arm
Some common exercises for the rotator cuff include:
-Lying external rotation
-Elbow on knee external rotation
-Arm abducted to side external rotation
