Risk of movement of parallel bar support! Side bar support shoulder injury

The risk of movements of parallel bar support!

The parallel bar support has always been considered a good training movement. It can help us develop upper limb strength and improve the coordination of the whole body

However, many people also experience shoulder discomfort or even injury when doing parallel bar support

It is because the risk of shoulder injury is too high that many trainers and coaches do not recommend doing this movement often

Eric, a well-known physical fitness coach in Major League Baseball Cressey mentioned on his personal website that the parallel bar support is a sport he will never give to baseball pitchers or players who hold their hands above their heads (tennis, swimming, volleyball...).

The parallel bar support will put the humerus close to the limit of extension during the centrifugal decline phase, which will put the shoulders in a very unstable state, especially athletes in events with both hands above their heads, or baseball pitchers already have a lot of shoulder external rotation during the exercise. If the shoulder is repeatedly stretched in the parallel bar support, it will easily cause the so-called Anterior Shoulder Instability.

Anterior Shoulder Instability. When the stability of the cuff and scapula is not very good, you can only rely entirely on the biceps long-cep tendons and the protection of the glenohumeral ligaments to prevent the humeral head from causing the damage to the forward dislocation (Popping Forward;Anterior Dislocation). Under repeated parallel bar support movements, these tendons and ligaments will be forced to lengthen, which will cause the sagging of the Anterior Capsule and humeral tendons, or deterioration in excessive use.

The well-known major league pitcher Johan Santana caused the forward unstable shoulder joints and the relaxation of the joint capsules under long-term practice and competition, and then performed anterior capsule suture (Anterior Capsule). Plication) One of the very famous examples.

Although the tightness of the joint capsule was restored after the operation, in order to be able to pull the arch backwards with a large arch back when the pitching was pulled back, it still took a long-term path of rehabilitation. Or the situation was worse, it had caused the so-called terminally ill labrum joint tear (Labrum) Tear).

The extreme extension state of the humerus when the parallel bar support is centrifuged downward, which is very similar to the symptoms of the forward instability of the shoulder joint due to the long-term external rotation of the shoulder. However, if you use a stool to do the parallel bar support movement, the situation will be even worse, because before you start the centrifugation downward movement, the shoulder joint has been stretched out.

Conclusion:

1. Let players who are overshot in the parallel bar support movement are definitely not a good choice .

2. For general generals, if you do not have a good posture, excellent shoulder rotator sleeve function, and good shoulder belt stability, you may not be suitable for this action, let alone a history of shoulder injury.

3. Especially if people with acromioclavicular pain or chronic pain in this area should stay away from this action.

4. This action is not recommended to anyone, because if your purpose is to practice chest and triceps, you will have better choices of movement.
