Why Do Swimmers Get Shoulder Pain?

Swimming may lead to shoulder pain due to repetitive overhead strokes, continuous rotational movement, and prolonged strain on shoulder muscles and connective tissues.

Key Takeaways

• Repetitive strokes can strain the shoulder.
• Continuous rotation places ongoing stress on tissues.
• High training volume may increase irritation.
• Muscle fatigue can affect shoulder stability.
• Proper recovery supports shoulder function.

Introduction

Swimming is a full-body activity that heavily engages the shoulders during nearly every stroke. Whether performing freestyle, backstroke, or butterfly, the shoulder plays a central role in movement and propulsion.

Because of this constant use, the shoulder is exposed to repetitive motion and sustained effort. Understanding what causes shoulder pain can help explain why swimmers sometimes experience discomfort.

Repetitive Overhead Strokes

Swimming involves repeated overhead arm movement.

Each stroke requires the arm to lift, rotate, and pull through the water. Over time, this repetitive motion may place strain on the muscles, tendons, and ligaments around the shoulder.

Frequent swimming sessions may increase this cumulative stress.

Continuous Rotational Movement

Swimming strokes rely on ongoing rotation.

Freestyle and backstroke involve repeated shoulder rotation as the arms move through the water. This continuous motion may place ongoing stress on connective tissues.

Without sufficient recovery, this may contribute to irritation or stiffness.

High Training Volume

Swimmers often train for extended periods.

Long swim sessions or frequent workouts may increase the workload placed on the shoulder. This sustained activity may lead to fatigue and strain in surrounding muscles.

Over time, this may contribute to discomfort or reduced mobility.

Muscle Fatigue and Imbalance

Fatigue can affect how the shoulder functions.

As muscles tire, they may provide less support and stability to the shoulder joint. This can alter movement patterns and increase strain on specific areas.

Imbalances between muscle groups may further contribute to stress on the shoulder.

Topical Recovery Support

Some individuals include topical therapies as part of their injury recovery approach to support tendons, ligaments, muscles, and connective tissues around the affected area.

For acute injuries such as a recent strain, sprain, bruise, or contusion, some people apply Acute Sinew Liniment to help relieve pain, reduce swelling and inflammation, and support the body’s natural healing response by helping disperse accumulated blood and fluids while increasing blood flow to injured tendons, ligaments, muscles, and surrounding tissues. Some people also use it alongside Sinew Herbal Ice during the early stage of injury to help reduce swelling and inflammation and stimulate circulation, further supporting the recovery process and helping to more quickly regain normal range of motion.

For chronic injuries that persist or linger, such as strains or sprains that are slow to heal, where swelling and inflammation have subsided but residual pain, stiffness, weakness, or sensitivity in cold weather remains, some people apply Chronic Sinew Liniment to help relieve pain, stimulate circulation and blood flow to affected tissues, and promote the healing of overstretched tendons and ligaments. Some individuals also use it alongside Sinew Injury Poultice to further stimulate circulation and promote deeper tissue recovery, particularly in areas affected by persistent stiffness or repeated strain.

For muscle preparation, performance, and recovery during exercise, sports, or strenuous activity, some people apply the Sinew Sports Massage Oil to help warm and stimulate muscles, increase circulation, and relieve muscle tightness.
