Breathing & Swimming – A Deeper Look at Performance and Imbalance

Swimming is one of the most beautiful displays of human movement—graceful, rhythmic, and powerful. But beneath that fluid exterior lies a unique set of physical demands that can lead to deeply ingrained imbalances if not properly addressed. This blog explores how breath, posture, and muscle coordination affect swimmers, and how a better understanding of breathing mechanics can help swimmers (and the rest of us) move and live better.

What Is Swimmer Dyssynchrony Syndrome?

Swimmer Dyssynchrony Syndrome describes a breakdown in the coordinated timing and function of muscles due to poor postural alignment and repetitive movement in compromised positions. In swimmers, this often stems from:

Forward head posture
Rounded and uneven shoulders
Weak or underdeveloped glutes
Tight low backs
Elevated ribs and hyperinflated chests

All of this is driven by thousands of repetitive strokes each week and the breathing demands of being face-down in water. Over time, these patterns create a predictable set of muscle imbalances.

Common Muscle Dyssynchrony in Swimmers:

Latissimus dorsi: Becomes a dominant internal rotator and restricts shoulder mechanics and rib cage mobility
Scalenes & SCMs: Take over as primary breathing muscles, increasing neck tension
Interscapular muscles: Become long, weak, and prone to fatigue, leading to shoulder issues
Back extensors & hip flexors: Become short and tight, overused for postural support and kicking

Why Breathing Is the First Fix

Breathing well out of the water is the gateway to performance in the water. A swimmer’s postural alignment and muscular firing sequence are directly influenced by diaphragm position. If the ribcage and pelvis are out of sync, the diaphragm becomes inefficient, forcing other muscles (like the neck, back, or hip flexors) to compensate.

When that happens, rotation suffers. So does shoulder function, spinal alignment, and ultimately stroke efficiency.

"Your breath is the rhythm that organizes your movement."

Here’s what every swimmer (and their coach or therapist) needs to prioritize:

Balanced Airflow & Rib Mobility:

Swimmers often become stuck in a hyperinflated chest posture
They must learn how to exhale fully, allowing the ribs to drop, then expand in all directions with inhalation

Anti-Gravity Strength for Stability:

Train hamstrings, glutes, abdominals, low traps, triceps, and internal rotators
These muscle groups form the foundation for joint health and power transfer

Restore Diaphragm Position & Function:

Use postural breathing exercises to anchor the ribs and train diaphragmatic inhalation from a state of exhalation

Release Tight Chains:

Focus on flexibility for hip flexors, pecs, paraspinals, scalenes, and external rotators
Dryland work should address full-body muscle balance, not just stroke-specific strength

Promote Reciprocal Movement Patterns:

Breathing only to one side while swimming reinforces postural asymmetries
Encourage bilateral breathing and exercises that promote rotation in both directions

Breathing Dysfunction = Movement Dysfunction

Breath holding, hyperinflation, and mouth-dominant breathing are common in swimming. But if these patterns follow swimmers onto land, they can wreak havoc:

Poor breathing habits out of the water limit rib mobility, spine rotation, and shoulder elevation
Accessory breathing overuse (neck and back) increases injury risk
Imbalanced muscle use leads to chronic pain or plateaus in performance

The Starting Point: Can You Exhale?

To start correcting these imbalances, begin with a simple question: Can you fully exhale and breathe in without lifting your shoulders or arching your back?

If not, that’s where your dryland training needs to start. Exercises like the 90/90 hip lift with balloon, All 4 belly lifts, or supported squats with breathwork help retrain the diaphragm, reposition the ribcage, and restore proper muscular coordination.

Final Thoughts

Swimmers may be amphibians in spirit, but they’re humans first—subject to the same postural patterns, asymmetries, and compensation strategies as the rest of us. A breath-centered approach to dryland training can help unlock better recovery, reduced injury risk, and more efficient movement in the water and out.
