Swimming with Shoulder Pain

Swimming with Shoulder Pain: What You Need to Know

Swimming is a fantastic full-body workout, but if you’re experiencing shoulder pain in the pool, you’re not alone. Shoulder injuries account for a significant portion of swimming-related pain, often referred to as “swimmer’s shoulder.” Understanding the specific range of motion (ROM) and rotator cuff demands placed on the shoulder during freestyle swimming can help you manage pain, improve technique, and prevent further injury.

Why Does Your Shoulder Hurt When You Swim?

Freestyle swimming requires a large range of motion in the shoulder and places high demands on the rotator cuff. If mobility, strength, or control are lacking, the shoulder joint can become irritated, leading to pain and inflammation. Many swimmers develop issues due to overuse, poor stroke mechanics, or underlying imbalances.

Understanding Shoulder Mobility in Swimming

To perform an efficient freestyle stroke, your shoulder needs adequate mobility in several key movements:

• Flexion (~180°): This allows for proper hand entry and forward reach. Limited flexion may cause excessive lumbar extension or a dropped elbow catch, leading to increased drag and shoulder stress.
• Abduction (90°-120°): Important for arm recovery over the water.
• External Rotation (90°-100°): Essential for a high-elbow catch, which helps maintain stroke efficiency and reduces strain on the shoulder.
• Internal Rotation (45°-60°): Helps complete the pull phase efficiently without excessive stress on the joint.
• Horizontal Adduction (30°-50°): Required for proper hand positioning at entry.
• Thoracic Mobility: Though not a shoulder-specific motion, adequate thoracic extension and rotation (~10°-20°) are necessary for an efficient freestyle stroke and to prevent excessive shoulder strain.

If you lack mobility in these areas, your body compensates in ways that can overload the shoulder, increasing your risk of pain and injury.

The Rotator Cuff Role in Swimming

Your rotator cuff consists of four muscles: supraspinatus, infraspinatus, teres minor, and subscapularis. These muscles help stabilize your shoulder joint, allowing for smooth movement and force generation in the water.

Each phase of the freestyle stroke places different demands on the rotator cuff:

1. Entry & Reach Phase:
   • The supraspinatus, infraspinatus, and subscapularis work to stabilize the shoulder as the arm reaches forward.
   • Poor control can lead to excessive movement of the humeral head.
2. Pull Phase (Catch to Mid-Pull):
   • High eccentric load on the external rotators (infraspinatus, teres minor) to control internal rotation.
   • The subscapularis contributes to internal rotation and force generation.
   • Weakness in these muscles can lead to inefficient pulling and increased stress on passive structures like the labrum.
3. Mid-Pull to Finish:
   • The subscapularis works to generate force through internal rotation.
   • The supraspinatus and infraspinatus continue stabilizing the shoulder joint.
4. Recovery Phase:
   • High eccentric demand on the external rotators to control rapid arm movement.
   • Fatigue or poor control in this phase can lead to anterior instability.

How to Address Shoulder Pain While Swimming

If you’re dealing with shoulder pain, it’s important to assess both your mobility and strength to identify potential deficits. Here are some key strategies to reduce pain and improve performance:

1. Improve Shoulder Mobility

• Thoracic Extension & Rotation: Thoracic mobility drills can help improve posture and reduce shoulder strain.
• Posterior Capsule Stretching: Address internal rotation deficits that can contribute to impingement.
• Lat & Pec Stretching: Reduces tension that may restrict overhead mobility.

2. Strengthen the Rotator Cuff & Scapular Stabilizers

• External Rotation Exercises: Band-resisted external rotation to strengthen the infraspinatus and teres minor.
• Scapular Stability Work: Exercises like prone Y’s and serratus punches to improve upward rotation.
• Eccentric Training: Slow, controlled external rotation movements to enhance fatigue resistance.

3. Modify Your Swimming Technique

• High-Elbow Catch: Ensures proper engagement of larger muscles (lats) instead of overloading the rotator cuff.
• Avoid Crossing Midline on Entry: Reduces excessive internal rotation stress.
• Bilateral Breathing: Promotes symmetrical movement and prevents muscle imbalances.

4. Adjust Training Load

• Reduce total volume and intensity if pain persists.
• Incorporate land-based strength training to improve shoulder durability.
• Consider alternative strokes like backstroke, which places less strain on the anterior shoulder.

When to Seek Professional Help

If you experience persistent shoulder pain, numbness, or weakness, consult a physical therapist who specializes in sports or swimming-related injuries. A thorough evaluation can help identify movement dysfunctions and provide a tailored rehab plan to get you back in the water pain-free.

Final Thoughts

Shoulder pain doesn’t have to end your swimming routine. By optimizing mobility, strengthening the rotator cuff, and refining stroke mechanics, you can reduce pain and improve your performance. Implementing these evidence-based strategies will not only help you recover but also prevent future injuries. If you’re struggling with persistent shoulder pain, don’t hesitate to seek professional guidance—your shoulders will thank you!
