The Basics of Breathing and Pressure

Breathing is an amazing example of natural engineering. Every breath involves dynamic changes in the pressures within our thoracic (chest) and abdominal cavities:

• Inhalation: When you take a breath in, your diaphragm contracts and moves downward while the intercostal muscles (between the ribs) expand the ribcage. This expansion increases the volume of your chest cavity and creates a negative pressure (a slight vacuum) relative to the outside atmosphere. This pressure drop causes air to rush into your lungs.

• Exhalation: Conversely, during exhalation, your diaphragm relaxes and moves upward, and the ribcage returns to its resting state. This reduction in volume increases the pressure inside the thoracic cavity, pushing air out of your lungs.

These natural fluctuations in pressure are essential for efficient gas exchange and overall respiratory function.

 

What Are Hypopressive Exercises?

Hypopressive exercises are a series of postural and breathing techniques designed to reduce intra-abdominal pressure and subsequently re-programme the body’s core muscles, including the pelvic floor, to manage pressure both consciously and sub-consciously. They were created and designed originally for:

• Pelvic Floor Health: Reducing intra-abdominal pressure can relieve stress on the pelvic floor muscles, which is beneficial for preventing or rehabilitating pelvic floor dysfunction.

• Core Strength: By indirectly activating deep abdominal muscles, these exercises support overall core stability.

• Posture: The mindful awareness of the alignment of spine and pelvis during these exercises promotes better posture.

• Stress & anxiety: The rhythmical breathing calms the nervous system

A key element of hypopressives is the controlled apnoea (breath-hold) phase, which amplifies the pressure changes initiated during the normal breathing cycle.

The Apnoea Phase in Hypopressives: Creating a “Vacuum” Effect

1. Starting Position and Exhalation

The hypopressive technique begins with a slow steady exhalation. This is crucial because it minimises the volume of air in the lungs and sets the stage for a significant pressure change. Unlike typical breathing where you might take a deep inhale, here the focus is on holding the air out to decrease the baseline internal pressure.

2. The Breath-Hold (Apnoea)

Once you've exhaled gently, you hold your breath. During this you perform the unique breath - the apnoea:

• Diaphragm Movement: The diaphragm, no longer pulled down by the act of inhalation, moves upward slightly. This repositioning further decreases the intra-abdominal pressure.

• Pressure Differential: With the nose and mouth closed, no new air is entering or exiting the lungs. The resulting pressure differential creates a kind of “suction effect” within the abdominal cavity.

• Activation of Deep Muscles: This vacuum-like state gently pulls the internal structures—especially the pelvic floor and deep abdominal muscles—into action. Rather than contracting in a conventional way, these muscles are subtly activated as they respond to the reduced pressure environment.

3. Postural Alignment

Simultaneously, hypopressive exercises emphasise proper posture—often involving elongation of the spine and a neutral pelvic position. This alignment not only enhances the efficiency of the apnoea but also helps distribute the pressure changes evenly across the core and pelvic regions.

 

Why Does It Work?

The underlying physics of hypopressive apnoea is all about pressure differentials. When you hold your breath after a full exhalation, the internal pressure drops below atmospheric pressure. According to principles similar to those in fluid dynamics (think of how a suction cup works), this creates an inward pull. In the human body, this “suction” can:

• Reduce Intra-abdominal Pressure: A lower pressure within the abdomen decreases the load on the pelvic floor, potentially reducing issues like pelvic organ prolapse.

• Enhance Muscle Activation: The body naturally recruits stabilising muscles, including those deep within the core, to counteract and adjust to the pressure changes.

Over time, regular practice of hypopressive exercises can contribute to better core stability, improved posture, and enhanced pelvic floor health.

Putting It All Together

The interplay of breathing and pressure is a fundamental part of how our bodies function, and hypopressive exercises take full advantage of this relationship. By mastering the art of controlled breathing, slow breathing, and a mindful apnoea phase, you create a beneficial vacuum effect that helps tone the deep core and pelvic floor muscles.

Whether you’re looking to improve your core strength, enhance your posture, or address pelvic floor concerns, understanding these pressure dynamics can empower you to make the most of your hypopressive practice.

So who can benefit?

Anyone and everyone, especially with our prevailing sedentary lifestyles. However, people with the following specific conditions often experience immense benefits:

• All types of Incontinence including men post prostatectomy

• Pelvic organ prolapse

• Hernias

• Poor posture/back pain

• Leakage when exercising

• Sports people that want to increase their aerobic capacity/improve their sports performance

• Protruding stomachs that traditional abdominal exercises hasn’t addressed

• Promotion of healing of diastasis recti

• General enhancement of pelvic and core health

• Improvement in intestinal function

• Prevention of hemorrhoids

 

Final Thoughts

Breathing is something we do every day without a second thought, yet it holds incredible potential for health and wellness. The apnoea phase in hypopressive exercises is a powerful tool that harnesses natural pressure changes to benefit your body in subtle yet significant ways. With regular practice and mindful attention to your posture and breathing, you can tap into these benefits and support a healthier, stronger core.
