What are baseball, tennis, and softball have in common? They are all spring sports that require intense activity overhead. Whether it will throw or serve, there is the potential to overload and aggravation to the shoulder joint.

Shoulder injuries are the fifth most common injury in high school athletes. While many of them are collision injury, as much as 42 percent of those injuries non-contact.

The shoulder is the most mobile joint in the human body and because of this, there is a fragile equilibrium between stability and mobility. This is referred to as “the dilemma of the pitcher.”

To understand the shoulder injury, one of the first athletes to understand what it takes to make a throw or hit the serve. First, the shoulder blades should be strong and move correctly around the rib cage. Without a strong s platform from shoulder blade to shoulder arms to continue, you will not reach a maximum speed of. If the arm does not move properly, then you can set yourself up to the injury. The second is the actual shoulder flexibility and range of motion (ROM). There is a structure in the shoulder is called capsule which allows just enough motion but prevented a joint dislocation. But, when it was repeatedly traumatized by throwing or serving, it can become too tight or even too loose. It is noted, however, that if you’re someone who frequently participate in sport shoulder range of motion overhead, will change and not necessarily for the worse.

The last aspect of toss to understand is the kinetic chain. The kinetic chain basically referring to transfer troops from your feet to your wrist and everything in between. The kinetic chain can easily be overlooked when athletes shoulder pain, but many times the problem can be made or at least exacerbated by the weakness or loss of flexibility in the legs and trunk. Research has shown that 54 per cent of the throw or serve comes from the legs, hips and trunk.
