What is Adaptive Oxygen Training (AOT) ?

ChatGPT Image May 27, 2026, 02_57_03 PM_edited.jpg

Adaptive Oxygen Training (AOT) is Rosalba Courtney’s integrative program that combines Intermittent Hypoxic–Hyperoxic Training (IHHT) with tailored breathing therapy.

 

IHHT is delivered while you sit comfortably in a chair, so your cells can be gently “trained” to use oxygen more efficiently without physical exertion.

​

Alongside this, you receive individual breathing assessment and exercises to improve breathing patterns such as over‑breathing or shallow chest breathing. Together, these methods aim to support people living with chronic fatigue, dysautonomia and breathing-related conditions, as well as athletes wanting better performance, recovery and resilience.

.

How it works

IHHT works by giving you short, gentle “training sessions” with changing oxygen levels, a bit like interval training for your cells. This helps your body use oxygen more efficiently and refresh tired mitochondria, which can support better energy and resilience over time.

​

These same mechanisms can support people with long‑lasting fatigue, dysautonomia and breathing issues, and can also help athletes recover better and perform at a higher level. By improving oxygen delivery, circulation and stress tolerance, IHHT can help you do more with less strain on your body.

Who it helps

Whether you’re an athlete seeking performance gains, or you want to restore vitality, support longevity, or support the body's healing response, AOT helps develop resilience from the cellular level upward

​

For those seeking general wellbeing, IHHT can support energy, stress resilience, and overall vitality. Many people use it to improve how they feel day to day, enhance recovery from life’s demands, and support healthy ageing.

​

IHHT is also used in more complex or chronic conditions, including ME/CFS, Long COVID, post-viral fatigue, and autonomic disorders such as POTS. In these cases, it is applied carefully to support energy production, nervous system regulation, and gradual recovery.

​

For athletes and active individuals, IHHT offers a way to enhance endurance, improve recovery, and build physiological resilience. By supporting oxygen delivery and utilisation, it can help optimise performance without adding additional physical strain.

Our programs

We offer several pathways depending on your goals, current health and level of support needed.

Our programs are for you if you are managing a specific health conditions, if you are health-conscious and seeking to optimise your wellbeing, and also, if you are an athlete or seeking to improve your performance .

​

We welcome referrals and work closely with clinicians to ensure our AOT protocols align with existing care plans. We value a collaborative approach and recognise that individuals with medical conditions benefit most from well-coordinated, multidisciplinary care.

Initial Assessment

We recommend an initial assessment for anyone who would needing individualised program or added clinical support.

 

We will review your history, goals, current symptoms, and relevant medical or clinical information so we can recommend the most appropriate pathway for you. 

Wellbeing Program

This pathway is designed for people who want to improve energy, resilience, and overall wellbeing. It is suitable for those looking to restore vitality, build adaptive capacity, and support healthy reconditioning.

Program if you're managing a health condition

This program is designed to fits with your medical care and any current lifestyle, breathing, stress-management, or rehabilitation strategies. This is tailored to best complement your broader treatment plan.

Performance program

This is for you to work with your athletic performance, recovery or general optimisation - an initial assessment is usually not required. This is your programs if your goals include stamina, repeated-effort capacity and faster recovery between training sessions.

 

Goals: Stamina, recovery, repeated-effort capacity.


Focus: Oxygen efficiency, nervous system regulation, and faster recovery between sessions.

Why work with us?

Our work is grounded in the understanding that adaptive oxygen training is not simply a machine-based exposure.

 

Meaningful results depend on matching the stimulus to the individual, which is why every program is guided by careful assessment of physiology, breathing patterns, adaptive range, and clinical or performance goals.

 

When needed, we integrate breathing retraining and broader regulatory support so the process is not only effective, but appropriate, sustainable, and safe.

FAQ

Questions often asked..

Is it safe? 

IHHT supports the way your heart, blood vessels, metabolism and brain respond to everyday demands, helping the body adapt more efficiently to stressors. Adaptive hypoxic conditioning does not only act on individual cells; it also influences how the heart, blood vessels, metabolism and brain respond to everyday demands. When the dose and pattern are carefully controlled, it can help support more efficient cardiovascular regulation, better metabolic flexibility, improved energy and improved stress resilience. Intermittent hypoxia conditioning triggers a cascade of beneficial physiological adaptations spanning multiple organs and systems simultaneously — from the cardiovascular and respiratory systems to the brain and metabolic pathways. Rather than targeting a single condition, this makes IHHT a compelling non-pharmacological strategy with broad health potential, particularly when doses are carefully calibrated to remain in the therapeutic range.

Fatigue and reduced exercise tolerance

Intermittent hypoxia–hyperoxia training protocols in clinical studies have been associated with improvements in perceived fatigue, aerobic capacity, and exercise tolerance in individuals with low baseline energy or deconditioning. These changes are often described as gradual adaptations rather than immediate symptomatic relief.

A note on dose and context

 

The distinction between harmful and helpful intermittent hypoxia is primarily one of dose, pattern and duration.
 
The kind of chronic, uncontrolled, severe oxygen drops associated with obstructive sleep apnoea are very different from the brief, mild, structured exposures used therapeutically.
 
Well-designed IHHT protocols are monitored and individually adjusted — and the current evidence consistently supports safety and tolerability across a range of populations when delivered appropriately.
