SHOULDER
IMPINGEMENT
Rotator cuff impingement in swimmers and triathletes — one of the most common and most mismanaged injuries in endurance sport. Swim-specific management at Five Dock, Inner West Sydney.
Swimmer's Shoulder — What's Actually Happening
Shoulder impingement in swimmers involves compression of the rotator cuff tendons — most commonly the supraspinatus — in the subacromial space during overhead movement. In swimming, this occurs at the catch and pull-through phases of freestyle and butterfly, where the shoulder is loaded in an internally rotated, elevated position.
The term "swimmer's shoulder" covers a spectrum of pathology — from early rotator cuff tendinopathy through to partial and full thickness cuff tears. The management depends significantly on which structure is involved and how severe the involvement is.
Critically, swimmer's shoulder is rarely just a shoulder problem. Technique, stroke volume, training load, and scapular mechanics are almost always contributing factors — and rehabilitation that doesn't address these will result in recurrence.
Why Swimmer's Shoulder Develops
Shoulder impingement in swimmers is almost always multifactorial. Identifying and addressing all contributing factors is essential for durable recovery.
Technique Factors
Hand entering across the midline increases internal rotation load on the shoulder — a very common technique fault that significantly increases impingement risk.
A low elbow position at the catch reduces propulsion efficiency and increases the compressive load on the rotator cuff during the pull-through phase.
Unilateral breathing creates asymmetrical shoulder loading — the non-breathing side experiences higher impingement forces due to body roll compensation.
Load & Strength Factors
Sudden increases in swim volume are the most common trigger for swimmer's shoulder — the rotator cuff has insufficient time to adapt to the increased repetitive loading.
Insufficient strength in the external rotators and lower trapezius allows the humeral head to migrate superiorly during overhead loading — compressing the subacromial structures.
Poor scapular upward rotation reduces subacromial space during arm elevation — a very common finding in swimmers with shoulder impingement that must be addressed in rehabilitation.
Swim-Specific Shoulder Rehabilitation
Generic shoulder rehab doesn't work for swimmer's shoulder. The management must account for the specific demands of the stroke, the volume of training, and the technique factors contributing to the injury.
Rotator cuff strength, scapular control, painful arc, impingement tests, and swimming history. Imaging referral where indicated to identify rotator cuff tears or other structural pathology that changes management. Dave's own swimming background informs how he assesses shoulder function in a swimming context.
Modification of swim volume while the shoulder settles. Specific strokes, sets, and hand paddles are modified based on which movements are provocative. Complete cessation of swimming is rarely necessary — but unmanaged continuation of high volume always prolongs recovery.
Progressive rotator cuff and periscapular strengthening — targeting the specific weakness patterns identified on assessment. Progressed from low-load through to high-load and velocity-specific exercises that reflect the demands of swimming.
Where technique factors are identified, we work collaboratively with the swimmer and their coach to address them — not through arbitrary restriction, but through practical modifications that reduce impingement loading while maintaining performance. Return to full training volume is graduated and monitored.
FAQ
Usually not — but the volume and the type of swimming needs to be modified while the shoulder is irritated. Continuing at the same load that caused the problem will prevent recovery. We'll work out a modified training plan that allows you to keep swimming while rehabilitation progresses.
Yes — running and cycling do not significantly load the shoulder and can be maintained throughout rehabilitation. Swimmer's shoulder doesn't need to derail your entire triathlon training — just the swim component requires modification.
Yes — Dave is an Ironman All World Athlete with extensive personal swimming experience in triathlon. He understands the specific demands of open water and pool swimming, how stroke mechanics affect shoulder loading, and how to manage shoulder rehabilitation in the context of a full triathlon training program.
