Volleyball shoulder injury

Hello. This article about shoulder injuries in volleyball, it consists of two parts: from my personal experience, where I tell you what to do to at least reduce shoulder pain during an attack and to get rid of it completely. The second part is theoretical, which describes the principles of the shoulder cuff and how it is injured.

How I treated my sore shoulder
And so, how to treat a sore shoulder? First of all, you need to determine the cause of the pain. It is necessary to go to the doctor, do an ultrasound or MRI. Further action is necessary to rest the arm for a recovery period. If you do not remove the traumatic factor, recovery will go much more slowly.

At one time, the author of this site also received a shoulder injury – inflammation of the tendon of the infraspinatus muscle. Below I will write what I had to do with my shoulder – what helped, and what seemed pointless. (But, attention! This is a personal subjective opinion of the author. This does not mean that in your case it will be absolutely identical. If you experience pain, be sure to consult a doctor! Determining the initial stage of injury will give you a faster chance of recovery, as well as prevent serious complications.)

It helped

UVT – shock wave therapy (the most effective remedy for pain, it is worth using if the pain is very strong, but you need to play)
Gym (for a volleyball player – it is necessary to strengthen muscles and ligaments) + use of rubber to strengthen the ligaments
Shoulder Stretch
Warm ointments before training or playing
Massage, pool
Did not help

All kinds of ointments and compresses
Magnetotherapy and other physiotherapy

And what helps you, and what turned out to be useless? Write in the comments.

The second (theoretical) part. If you are familiar with the general structure of the shoulder joint, the mechanism of shoulder injuries will be clear to you. Consider some of the components of the shoulder joint in more detail.

Rotational cuff of the shoulder joint
Rotational cuff of the shoulder joint The rotational cuff is the combination of several muscle tendons that strengthen the shoulder joint. These tendons merge with each other and with the joint capsule, thus, in the region of the shoulder joint, a single connective tissue cover is formed. In front of this cuff is the tendon of the subscapularis muscle, and from the back, the tendon of the infraspinatus and the small circular muscle. In its upper part, the cuff is formed by the tendon of the supraspinatus muscle. The inside of the shoulder joint is lined with the synovial membrane. The same membrane forms two protrusions (“bags”), through them the subscapularis muscle and the tendon of the long biceps head penetrate into the cavity of the shoulder joint. In the area of ​​the shoulder joint there are also sub-fake and subacromial bags, they are not communicated with the joint cavity, but are interconnected.

The acromial-brachial joint, or “supraspinous exit,” is a key point in the physiology of many shoulder injuries. This is the only place in the human body with muscles or tendons located between two bones. In this place, with almost any physical activity, the supraspinatus tendon and muscle can be caught between the humeral head and acromion. Sometimes another pair of muscles is “trapped” – the infraspinatus and subscapularis.

Throwing Mechanism
With active physical activity, the athlete performs movements in the shoulder joint with maximum amplitude, and the angular velocity is extremely high. This predisposes the shoulder joint to injury – both acute and chronic.

In general, the shoulder joint in many sports disciplines is not subjected to such serious loads as the joints of the lower extremities when running and jumping. Nevertheless, with the abduction of the arm at 60-90 degrees, the reaction force in the shoulder joint can reach 90% of the athlete’s body weight. If at the same time the movements will be repeated many times – the load on the shoulder joint will be even more so.

The mechanism of propelling movements consists of three components: lifting, acceleration, tracking. When lifting, the athlete takes the humerus 90 degrees, while it turns out to be maximally bent in the horizontal plane, also turned outward. And it takes a tiny amount of time – about one sixth of a second. In this case, the torque that acts on the anterior capsule of the joint can reach 17,000 kg / cm. This movement is mainly the result of the work of the deltoid muscle, and the participation of the rotational cuff is minimal. This movement ends with the work of two more muscles – the pectoralis major and latissimus dorsi.
