Swimming is a low-impact, full-body workout enjoyed by people of all ages. For most recreational swimmers, the risk of injury is low. However, competitive swimmers or those who train for long periods can develop overuse injuries, especially shoulder labral tears.
At Southlake Orthopaedics, we help swimmers stay healthy by explaining why these injuries happen, how to prevent them, and when to seek care before the damage becomes more serious.
What Is a Shoulder Labral Tear?
The labrum is a ring of cartilage that surrounds the shoulder socket. It serves two important purposes:
• It deepens the socket to help keep the arm bone in place
• It provides attachment points for ligaments and tendons
Repeated overhead movements—like swimming strokes—can gradually wear down this cartilage. Over time, that stress can lead to a tear. Labral tears may also happen suddenly after a fall, collision, or shoulder dislocation.
Tears can occur in different areas of the labrum. The most common types include:
Posterior Labral Tear: The rarest type, usually caused by a direct blow to the back of the shoulder. This injury requires prompt medical evaluation.
Bankart Tear: Often seen in younger patients or after a shoulder dislocation. This tear affects the lower part of the labrum.
SLAP Tear (Superior Labrum Anterior to Posterior): The most common labral tear. It runs from the front to the back of the top of the labrum and may involve the biceps tendon. SLAP tears are frequently seen in swimmers and other athletes who use repeated overhead motions, such as baseball players, tennis players, weightlifters, and gymnasts.
Why Swimmers Are at Higher Risk for Labral Tears
Swimming places unique stress on the shoulders. Unlike runners, who rely mostly on their legs, swimmers generate nearly all forward movement with their upper body. In fact, up to 90% of propulsion comes from the shoulders and arms.
Each stroke forces the shoulder through extreme ranges of motion while pushing against water resistance. During freestyle, butterfly, and backstroke, the arm rotates under load while the shoulder joint works to stay stable. This creates repeated strain on the labrum.
The risk of injury rises when swimmers become fatigued or use poor technique. For example, crossing the hand too far across the body when entering the water can pinch the shoulder joint and increase stress on the labrum. Over time, the muscles that normally protect the shoulder can tire out. When this happens, the arm bone moves more loosely in the socket, which can cause the labrum to fray and tear.
How to Prevent Shoulder Labral Tears in Swimmers
Labral tears are not inevitable. Swimmers can lower their risk by taking a few key steps:
Warm up with movement: Use dynamic warm-up exercises before swimming instead of long, held stretches. Arm circles and upper-back twists help increase blood flow and prepare the shoulder joint for activity.
Strengthen the shoulder muscles: The rotator cuff and shoulder blade muscles help keep the arm bone centered in the socket. Resistance band exercises and controlled shoulder raises can improve stability.
Increase training gradually: Avoid sudden jumps in distance or intensity. A good guideline is to increase training volume by no more than about 10% per week to give the shoulder time to adapt.
Maintain proper technique: Good form reduces unnecessary stress on the joint, especially when fatigue sets in. Paying attention to hand entry and body position can protect the shoulder over time.
Symptoms of a Shoulder Labral Tear
Early detection of a shoulder labral tear can make recovery easier and faster. Warning signs may include:
Deep, hard-to-locate shoulder pain: This pain feels buried inside the joint rather than on the surface and does not improve with massage or stretching.
Clicking or catching sensations: You may feel popping, locking, or a brief “catch” when moving your arm overhead.
Shoulder instability: The shoulder may feel loose, weak, or like it might slip out of place during the pulling phase of a stroke.
Loss of strength or motion: You may notice reduced power in your stroke or difficulty lifting your arm fully.
Need for medical evaluation: If these symptoms appear, prompt evaluation is important. Early treatment can help prevent long-term damage and shorten recovery time.
When to See an Orthopaedic Specialist
Shoulder labral tears should never be ignored. Persistent shoulder pain, weakness, or instability deserves professional attention, especially for swimmers who want to stay active long-term.
If your shoulder pain is keeping you out of the pool or affecting your performance, don’t wait. The team at Southlake Orthopaedics is committed to providing compassionate, expert care to help you heal and return to the activities you love.
