Both the shoulder and the elbow are susceptible to injury at this position. The biceps brachii and supraspinatus are shown to be initiated or excited by these mechanoreceptors and assist with prevention of anterior instability.
Injuries to the shoulder in the throwing athlete. That is usually the journal article where the information was first stated. Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare overhahd.

One essential property is the utilisation of a kinetic chain to generate and transfer energy from the larger body parts to the smaller, more injury-prone upper extremity.
Physiopedia articles are best used to find the original sources of information see the references list at the bottom of the article. Implicatiins Editors Categories Share Cite.
Simultaneously the pectoralis major, subscapularis, and serratus anterior are inhibited. Note the 15 degree angle of the foot away from the center of the mound . This finding is consistent with the anterior glenohumeral instability found in many throwing athletes and emphasizes the importance of proper mechanics throughout the entire kinematic chain .
The arm deceleration phase begins at ball release and ends at maximum shoulder internal rotation . Fleisig emphasizes the importance of these values by describing the change in force exhibited on the shoulder when they deviate from the norm.

The picture below depicts an overhead view of the alignment of the body during the acceleration phase of throwing. This kinetic chain in throwing includes the following biomehcanics of motions: Topics Discussed in This Paper.
Proper throwing mechanics may enable an athlete to achieve maximum performance with minimum chance of injury. During this phase the muscle activity is quite low and for these reasons risk of injury is low as well .
Typically the concern in this phase is safely decelerating the forward progression of the arm. Please note that decreasing the distance ovrehand from center or decreasing the angle did not result in increased anterior force on the shoulder. Shoulder and elbow muscles produce large compressive forces to resist joint distraction. Overtime the excessive utilization of the biceps brachii could lead to a superior labrum anterior to posterior Bimechanics tear.

When these actions cannot be preformed there is increase likelihood of anterior instability of the glenohumeral joint .
While quantifiable differences do exist in proper mechanics for various sports, certain similarities are found in all overhand throws. Showing of extracted citations.
