Shoulder pain in volleyball players: causes and prevention

Shoulder pain in volleyball players almost always comes from overload, not from a trauma. Thousands of spikes and serves ask the rotator cuff for the same thing: accelerate the arm, then brake it. Braking is the hard part, and that is where the damage piles up. You prevent it with two levers: keeping the volume of hits under control, and training the muscles that stabilize the shoulder blade and decelerate the arm, which are almost always the most neglected.

What causes shoulder pain in volleyball

Shoulders do not break all of a sudden. They wear out. In the vast majority of cases the pain is the result of several factors adding up over the same period.

Overload from hitting volume

This is the first cause, and the most underrated. The total number of attacks plus serves in a week — what in English is called swing volume — weighs more than anything else. A session of nothing but repeated attacks, a week with double practices, a long tournament: those are the moments when the rotator cuff gets more work than it can recover from.

Years of practice stacked up

The more years you play, the more hits your shoulders carry. It is not a sentence, but it changes the priorities: an athlete with many seasons behind them needs more prevention work and more recovery than a kid in their second year, with the same training load.

No real break

If you go from the indoor season straight into summer beach volleyball without ever stopping, you never give the shoulder a window to repair. Even a deload phase of a few weeks, where you cut down overhead hitting and keep only strength and mobility, makes a real difference.

Stiffness and loss of range of motion

The repeated braking movement after contact creates areas of shortening and tightness in the back of the shoulder. The result is internal rotation that shrinks over time. Less mobility means that, to make the same movement, the arm has to look for range somewhere else — and it finds it in places that should not be giving it.

Technique and execution errors

A serve or an attack hit with the arm too low, with little trunk rotation, or with the elbow dropping below the line of the shoulder, dumps tension where it does not belong. Even a messy jump that leaves you hitting off balance gets paid for by the shoulder.

Acute trauma

These are the minority of cases, but they exist: falls, contact at the net, sudden movements while diving. Sprains, dislocations, ligament injuries. Here the path is not prevention but medical diagnosis — if you have had an acute episode, the first stop is a specialist.

The biomechanics of the movement: five phases

The shoulder does not work alone. It is the middle link of a kinetic chain that starts at the feet and ends at the hand: legs, hips, trunk and arm fire in sequence, and each segment passes energy to the next. If a link upstream does not do its part, the shoulder has to produce force on its own that is not its job. Here is how the attacking movement breaks down.

1. Wind-up (swing and first loading). The shoulder rises into abduction and starts to externally rotate. The rotator cuff switches on to hold the head of the humerus in place.
2. Cocking (loading). The shoulder reaches maximum external rotation. Infraspinatus and teres minor produce the highest force peaks of the whole movement and protect the front of the capsule from the humerus translating forward. It is by far the most demanding phase.
3. Arm acceleration. The movement reverses: the shoulder internally rotates very fast and the arm accelerates towards the ball. This is the propulsive phase, the one that generates ball speed.
4. Contact. The arm is high and extended, the hand hits. The power released into the ball produces a high level of vibration that travels back up the limb.
5. Follow-through (deceleration). The arm has to stop. The cuff works eccentrically to brake it, and this is the phase where most of the chronic damage builds up. If you do not train deceleration, you are only training half the movement.

Prevention: what to actually train

You protect the shoulder by working on four fronts, in this order of priority.

Shoulder blade stabilizers. Lower trapezius, serratus anterior, rhomboids. If the shoulder blade does not move well on the ribcage, the head of the humerus loses its space and the cuff suffers. Rows, band pull aparts, suspension exercises.

External rotators and eccentric work. Band external rotations with the elbow fixed and at 90 degrees, with the emphasis on a slow return phase. It is the movement that mimics the arm braking.

Internal rotation and thoracic spine mobility. Sleeper stretch, cross-body stretch, thoracic extensions. Getting degrees of rotation back takes compensation away from the shoulder.

The chain upstream. Core, glutes, trunk rotation. A powerful attack starts from the legs: if the drive from below is missing, the arm tries to make up for it.

On top of that come the basic habits: a specific warm-up before you hit (not just a jog and some stretching), a sensible balance between strength and mobility work, proper shoes, and a load that grows step by step.

If the pain lasts for weeks, wakes you up at night or takes strength out of your arm, it is no longer something to manage on your own: see a doctor or a sports physio.

Measure first, then train, then measure again

The attacking movement is jump plus arm: the two travel together. When the shoulder starts to bother you, the first reaction is to change something in training — but without an objective reference you have no idea whether you are improving or just piling on load.

The fastest way to get that reference is the free jump test: you upload a two-second video of yourself jumping, the system works out the height from the flight time and gives you the number in centimetres. The video never leaves your device. Redo it every four to six weeks: if your jump drops while you are training the same way, that is often the first sign that you are accumulating more fatigue than you are recovering.

JHP programs for the shoulder and the attack
