The Science of Breath in Pilates: How Diaphragmatic Breathing Improves Oxygen Flow and Reduces Cortisol

Breathing is an essential, involuntary function that powers all bodily systems, but how we breathe can have a profound impact on our physical and mental well-being. In Pilates, breath is not only a means of sustaining life but also a crucial tool for enhancing performance, improving oxygen flow, reducing stress, and supporting recovery. The most significant breath technique used in Pilates is diaphragmatic breathing, which engages the diaphragm in a way that deepens each breath, maximises oxygen delivery, and helps regulate the autonomic nervous system.

In this blog post, we will dive into the physiology behind Pilates breathing techniques, with a particular focus on diaphragmatic breathing. We will explore how this breath technique reduces cortisol (a primary stress hormone), improves oxygen flow to muscles, and supports recovery. Additionally, we’ll look at specific Pilates exercises where breathwork can be used to enhance performance.

 

Understanding Diaphragmatic Breathing

Diaphragmatic breathing, also known as abdominal or deep breathing, involves the full engagement of the diaphragm, the large muscle located just below the lungs. When you inhale deeply using the diaphragm, your lungs expand fully, allowing for a greater intake of air and the delivery of more oxygen to the blood. This method contrasts with shallow chest breathing, which tends to be less efficient and can lead to increased feelings of stress or anxiety.

In Pilates, diaphragmatic breathing is integral to supporting movement and providing stability to the spine. When the diaphragm contracts, it creates intra-abdominal pressure, which helps stabilise the trunk and provides support for the spine during dynamic movements. This stabilisation is particularly important for exercises that engage the core, where breathwork supports both the muscles and nervous system.

The Physiology of Breathing in Pilates

Pilates breathing techniques are designed to activate the body’s natural breath patterns, improving both oxygenation and relaxation. Let’s explore how diaphragmatic breathing works from a physiological standpoint.

  1. Increased Oxygen Delivery
    Deep diaphragmatic breathing ensures that oxygen is efficiently delivered to the bloodstream. When we breathe deeply into the belly, we allow the lungs to expand fully, which increases the amount of oxygen that can be absorbed. This, in turn, enhances the body’s ability to perform during physical activities, as muscles require oxygen to function effectively. For Pilates practitioners, this means more sustained energy during sessions and improved endurance over time.

  2. Activation of the Parasympathetic Nervous System
    One of the most notable benefits of diaphragmatic breathing is its ability to activate the parasympathetic nervous system, often referred to as the "rest and digest" system. This part of the autonomic nervous system counteracts the "fight or flight" response associated with stress. By consciously engaging in deep, slow breaths, Pilates practitioners can reduce the production of stress hormones, such as cortisol, and promote a state of calmness and relaxation.

  3. Reduction of Cortisol Levels
    Cortisol is a hormone released in response to stress, and chronic elevated levels can have negative effects on health, including impaired immune function, increased fat storage, and disrupted sleep patterns. Studies have shown that diaphragmatic breathing reduces cortisol levels, promoting a more balanced hormonal environment. For Pilates practitioners, this means that the act of breathing deeply during exercises not only supports physical movement but also helps reduce stress and anxiety, creating a more balanced mental state.

  4. Improved Core Stability
    In Pilates, breath is closely tied to core stability. As the diaphragm contracts and expands, it creates pressure within the abdominal cavity that helps stabilise the spine. This is essential during core-focused Pilates exercises, where maintaining a neutral spine is key for both performance and injury prevention. Deep breathing enhances the effectiveness of these exercises by engaging stabilising muscles and providing additional support during movements.

How Diaphragmatic Breathing Enhances Pilates Performance

The integration of diaphragmatic breathing into Pilates exercises isn’t just about the act of breathing; it’s about synchronising breath with movement. The breathing technique should complement each phase of a movement, creating flow and efficiency. Here's how diaphragmatic breathing enhances Pilates performance:

  • Inhalation (Expansion): The inhale in Pilates is typically associated with lengthening, expanding the body, and preparing for movement. During an inhale, the diaphragm contracts downward, creating space for the lungs to fill with air and allowing the ribcage to expand. This action prepares the body for more challenging movements and increases flexibility by encouraging full expansion of the ribcage and torso.

  • Exhalation (Contraction): The exhale in Pilates is often linked with effort, control, and engagement of the core. During an exhale, the diaphragm relaxes, and the abdominal muscles engage to support the movement. Exhaling fully helps eliminate stale air from the lungs and reduces tension in the body, allowing for more controlled, fluid movement. A controlled exhale also helps activate the pelvic floor and deep stabilising muscles of the core, which are vital for maintaining spinal alignment.

How Diaphragmatic Breathing Reduces Stress and Enhances Recovery

Pilates is a low-impact exercise modality, but it can still put strain on the muscles, particularly when performed with precision and intensity. Recovery is essential to prevent overuse injuries and ensure that the body continues to function optimally. Diaphragmatic breathing plays a critical role in recovery by promoting relaxation, reducing muscle tension, and improving circulation.

When practising Pilates, taking time to focus on the breath can accelerate recovery in the following ways:

  1. Decreases Muscle Tension
    When the body is stressed, the muscles tend to tighten, which can lead to discomfort and fatigue. Deep breathing helps to reduce muscle tension by promoting relaxation throughout the body. By practising diaphragmatic breathing during Pilates exercises, individuals can maintain a relaxed and fluid state, allowing for smoother movements and better performance.

  2. Increases Circulation
    Diaphragmatic breathing also helps to increase blood circulation, which is essential for muscle recovery. As the diaphragm moves, it massages the internal organs and helps the heart pump blood more effectively throughout the body. This improved circulation aids in the delivery of oxygen and nutrients to the muscles while simultaneously helping to remove metabolic waste products, like lactic acid, which can build up after exercise.

  3. Supports Restorative Recovery
    Pilates sessions can also be used as a restorative practice, especially if diaphragmatic breathing is the focal point. By slowing the breath and focusing on deep, mindful inhalations and exhalations, practitioners can tap into the parasympathetic nervous system, helping the body shift into recovery mode. This promotes a state of relaxation and recovery, reducing the likelihood of overtraining or burnout.

Pilates Exercises That Integrate Diaphragmatic Breathing

Here are some Pilates exercises that can be enhanced by diaphragmatic breathing, promoting both oxygen flow and core stability:

1. The Hundred

This classic Pilates exercise is designed to build endurance and strengthen the core. The breathing pattern used here is an inhale for five counts and an exhale for five counts, coordinated with the movement of the arms.

  • How to do it: Lie on your back with your legs in a tabletop position and your arms extended by your sides. Lift your head and shoulders off the mat while engaging your core. Begin pumping your arms up and down in small, controlled movements while breathing deeply. Inhale for five counts, and exhale for five counts, maintaining a steady rhythm.

  • Breath benefits: The controlled exhale helps activate the core muscles, while the deep inhale ensures that the body remains oxygenated.

2. Pelvic Curl

The Pelvic Curl is a fantastic exercise for improving spinal articulation and engaging the core.

  • How to do it: Lie on your back with your knees bent and feet flat on the mat. As you inhale, prepare to lift your pelvis and engage your core muscles. Exhale as you slowly roll your spine off the mat, lifting your hips to create a straight line from your knees to shoulders. Inhale at the top, and exhale as you roll your spine back down, one vertebra at a time.

  • Breath benefits: Inhaling to prepare and exhaling during the roll-up ensures that the core is properly activated and the movement is controlled.

3. Swimming

This exercise targets the back muscles while enhancing balance and coordination.

  • How to do it: Lie face down with your arms extended overhead. Lift your right arm and left leg simultaneously while maintaining stability through your core. Switch sides, lifting your left arm and right leg, continuing in a flowing, alternating movement.

  • Breath benefits: Focus on inhaling deeply as you extend your limbs, and exhaling as you switch sides, engaging the core for stability.

4. The Saw

The Saw helps to stretch and strengthen the spine while also improving rotational mobility.

  • How to do it: Sit tall with your legs extended wide apart and your arms outstretched to the sides. Inhale as you prepare, then exhale as you rotate your torso towards your right leg, reaching your left hand toward your right foot. Inhale as you return to the centre, and exhale as you rotate to the left.

  • Breath benefits: Deep inhalations and exhalations allow for full spinal rotation while engaging the core to stabilise the torso.

Conclusion

Diaphragmatic breathing is a cornerstone of Pilates practice, offering numerous physiological benefits that enhance performance, reduce stress, and support recovery. By consciously engaging the diaphragm and breathing deeply, Pilates practitioners can improve oxygen delivery to the muscles, stabilise the core, and activate the parasympathetic nervous system, reducing cortisol levels and promoting relaxation. Integrating mindful breathwork into Pilates exercises not only helps to deepen the practice but also fosters greater mental clarity and physical resilience. With regular focus on diaphragmatic breathing, Pilates can become a powerful tool for both physical fitness and overall well-being.
