As the US open approaches, and captures the attention of tennis fans around the world, it’s easy to marvel at the speed and power generated by the game’s top players.
Modern professional serves can exceed 140mph (225km/h), with players producing extraordinary forces through the shoulder, spine, hips and legs.
In fact, many sports scientists consider the tennis serve to be one of the most powerful and complex movements in sport.
But with that power comes a price.
Whether you’re a competitive player, club member, weekend warrior or someone who enjoys a social hit with friends, the serve places enormous demands on the body; particularly the shoulder. It’s no surprise that shoulder pain is one of the most common reasons tennis players seek medical and physiotherapy advice.
So what makes the serve so challenging, what injuries can occur, and what can you do to protect your shoulder?
Why Is the Tennis Serve So Demanding?
The serve is often described as a full-body kinetic chain movement.
Power is generated from the ground up:
- Legs drive force into the court
- Hips and trunk rotate explosively
- The shoulder accelerates the arm
- The forearm and wrist transfer energy into the racket
- The body rapidly decelerates after ball contact
During the acceleration phase of the serve, the shoulder rotates at speeds exceeding 2,000 degrees per second. Very few sporting movements place such extreme stress through a single joint.
The shoulder is capable of this because it sacrifices stability for mobility.
Unlike the hip, which sits deeply within a socket, the shoulder resembles a golf ball balanced on a tee. This allows exceptional movement but also increases the risk of injury if the surrounding muscles are not functioning optimally.
Understanding the Shoulder – Why Stability Matters
The shoulder is made up of several joints working together, including:
- Glenohumeral joint (ball and socket joint)
- Acromioclavicular (AC) joint
- Sternoclavicular joint
- Scapulothoracic articulation (the shoulder blade moving over the rib cage)
A group of four muscles known as the rotator cuff helps keep the humeral head centred within the socket during movement.
These muscles include:
- Supraspinatus
- Infraspinatus
- Teres minor
- Subscapularis
However, the rotator cuff cannot work effectively without a stable foundation.
That foundation is the scapula – the shoulder blade.
The Often Overlooked Role of the Scapula
The scapula acts as the platform from which the shoulder operates.
During a tennis serve, the shoulder blade must rotate, tilt and stabilise in a highly coordinated manner. If this movement becomes altered due to weakness, fatigue or poor movement patterns, excessive stress can be transferred to the rotator cuff, labrum and surrounding tissues.
This phenomenon is often referred to as scapular dyskinesis.
Research has shown that altered scapular control is associated with many shoulder injuries seen in overhead athletes.
In simple terms, if the shoulder blade isn’t doing its job properly, the shoulder itself often pays the price.
Common Tennis Shoulder Injuries
Rotator Cuff Tendinopathy
This is one of the most common causes of shoulder pain in tennis players.
Repeated serving and overhead strokes can overload the rotator cuff tendons, leading to pain, weakness and reduced performance.
Symptoms often include:
- Pain when serving
- Discomfort reaching overhead
- Night pain
- Reduced power
Shoulder Impingement
Impingement occurs when structures within the shoulder become compressed during movement.
Players may experience:
- Pain during the serve
- Pain when lifting the arm
- A painful arc of movement
Modern understanding suggests this is often linked to movement control and loading issues rather than simple structural narrowing.
SLAP Tears and Labral Injuries
The labrum is a ring of cartilage that deepens the shoulder socket.
The extreme external rotation seen during serving can place stress on the labrum, occasionally resulting in tears.
Symptoms may include:
- Deep shoulder pain
- Clicking or catching
- Loss of power
- Feelings of instability
Shoulder Instability
In some players, repeated serving can contribute to excessive shoulder laxity or instability.
The shoulder may feel loose, weak or vulnerable during overhead activities.
Why Recreational Players Are Often More Vulnerable
Many amateur players assume these injuries only affect professionals.
In reality, club and recreational players are often at greater risk.
Unlike elite athletes, most recreational players:
- Play infrequently
- Have limited strength training
- Spend long hours sitting at desks
- Lack structured conditioning programmes
- Increase playing volume suddenly during summer months
A common scenario is someone who plays once a week but then spends an entire weekend tournament repeatedly serving at maximum effort.
The shoulder is rarely prepared for this sudden increase in load.
Scapular Stability and Rehabilitation – The Cornerstone of Recovery
While rest can temporarily reduce symptoms, successful long-term recovery usually requires addressing the underlying causes.
For most tennis-related shoulder injuries, physiotherapy remains the cornerstone of treatment.
A comprehensive rehabilitation programme often focuses on:
Improving Scapular Control
Key muscles include:
- Serratus anterior
- Lower trapezius
- Middle trapezius
- Rhomboids
Exercises may include:
- Wall slides
- Serratus punches
- Scapular push-ups
- Prone Y and T raises
Rotator Cuff Strengthening
Targeted strengthening helps improve shoulder stability and resilience.
Common exercises include:
- External rotation exercises
- Internal rotation exercises
- Isometric loading
- Progressive resistance training
Thoracic Spine Mobility
Restricted upper back movement can increase stress on the shoulder during serving.
Improving thoracic mobility often forms an important part of rehabilitation.
Kinetic Chain Training
The shoulder does not work in isolation.
Effective rehabilitation also addresses:
- Core strength
- Hip mobility
- Lower limb strength
- Whole-body movement patterns
Shoulder Stability Rehabilitation Programme
If you’ve experienced shoulder pain, instability or recurrent tennis injuries, a structured rehabilitation programme can make a significant difference.
Our dedicated shoulder stability rehabilitation programme has been designed to help improve scapular control, rotator cuff strength and overall shoulder function.
Whether you’re recovering from injury or looking to prevent future problems, progressive exercises and expert guidance can help you build a stronger, more resilient shoulder for sport and everyday activities.
Can Shoulder Injuries Be Prevented?
While not every injury can be avoided, the risk can often be reduced through sensible preparation.
Key strategies include:
- Strength training throughout the year
- Gradually increasing playing volume
- Regular shoulder conditioning
- Adequate recovery between sessions
- Maintaining thoracic and shoulder mobility
- Addressing symptoms early rather than playing through pain
Many players wait until pain becomes severe before seeking help. Early assessment and intervention often lead to faster recovery and a quicker return to the court.

Frequently Asked Questions
Is the tennis serve bad for your shoulder?
Not necessarily. A healthy shoulder can tolerate the demands of serving well. Problems typically arise when there is a sudden increase in load, poor technique, inadequate conditioning or underlying weakness.
What is the most common shoulder injury in tennis players?
Rotator cuff tendinopathy is one of the most frequently diagnosed shoulder conditions in tennis players, particularly those who perform large volumes of serving.
Why does my shoulder hurt after serving?
Pain after serving may result from overload of the rotator cuff, shoulder impingement, labral irritation, instability or poor scapular control. A proper assessment can help identify the underlying cause.
What exercises help tennis shoulder pain?
Exercises targeting scapular stability, rotator cuff strength, thoracic mobility and whole-body conditioning are often effective. The most appropriate exercises depend on the specific diagnosis.
When should I see a specialist about shoulder pain?
If shoulder pain persists for more than a few weeks, affects your performance, causes night pain, or is associated with weakness or instability, it is worth seeking professional assessment.
