What Is the Most Effective Oxygen Strategy for Athletes?
The most effective oxygen strategy depends on the goal.
Hyperbaric Oxygen Therapy (HBOT), hyperoxic training, Exercise With Oxygen Therapy (EWOT) and oxygen-enriched hydration all take different approaches to increasing oxygen availability.
While some interventions provide intensive oxygen exposure in controlled environments, others are designed to integrate naturally into everyday training and recovery routines.
For many athletes, the question is not simply which intervention delivers the greatest oxygen exposure.
It is which approach can be used consistently alongside training, recovery and everyday life.
Introduction
Oxygen sits at the centre of human performance.
Every training session, endurance effort and recovery process depends on the body's ability to deliver and utilise oxygen effectively. From energy production and cardiovascular function to recovery and adaptation, oxygen influences virtually every aspect of athletic performance.
For athletes, this ultimately comes down to three key outcomes:
-
Performance
-
Endurance
-
Recovery
This explains why oxygen-focused interventions have attracted growing attention across endurance, hybrid fitness and elite sport.
Athletes, coaches and researchers continue to explore whether increasing oxygen availability can influence training quality, recovery and long-term performance outcomes.
Today, there are several different approaches available, including:
-
Hyperbaric Oxygen Therapy (HBOT)
-
Hyperoxic training
-
Exercise With Oxygen Therapy (EWOT)
-
Oxygen-enriched hydration
Some require specialist facilities and equipment.
Others are designed for everyday use.
One example is KURE, an oxygen-enriched spring water developed to provide athletes with a practical way to incorporate oxygen-supported hydration into their existing training and recovery habits. (4)
In this guide, we'll explore how oxygen influences performance, compare the major oxygen-based interventions available today and examine why practical, repeatable solutions are becoming increasingly important within modern sport.
Why Oxygen Matters for Performance and Recovery
Oxygen and Energy Production
Every movement the body performs requires energy.
During exercise, oxygen plays a critical role in aerobic metabolism, the process through which the body converts carbohydrates and fats into adenosine triphosphate (ATP), the primary energy source used by working muscles.
This process takes place within the mitochondria and becomes increasingly important during sustained exercise.
VO₂ max, one of the most widely recognised measures of aerobic fitness, reflects the body's ability to consume and utilise oxygen during exercise. According to Harvard Health, higher VO₂ max values are generally associated with greater aerobic fitness and improved endurance capacity. (1)
For athletes competing in endurance, hybrid fitness and repeated high-intensity events, oxygen utilisation remains a key determinant of performance.
Does Oxygen Help Recovery After Exercise?
Oxygen remains important after exercise ends.
Recovery relies on a series of oxygen-dependent processes that help restore physiological balance following training stress.
Research into exercise metabolism has explored how oxygen availability may influence:
-
Lactate response
-
Energy metabolism
-
Substrate utilisation
-
Recovery dynamics
-
Perceived fatigue
Modern exercise science also recognises that lactate is not simply a waste product.
It acts as both a fuel source and a signalling molecule involved in energy regulation and physiological adaptation.
This has led researchers to investigate whether interventions that influence oxygen availability may also affect recovery-related processes.
For athletes, the practical question is not only whether oxygen matters.
It is whether oxygen-focused strategies can be used in a way that supports consistent recovery habits over time.
The Four Main Oxygen-Based Approaches Used by Athletes
Athletes currently have several options when exploring oxygen support.
However, these approaches differ significantly in accessibility, practicality and how they fit into everyday training.
1. Hyperbaric Oxygen Therapy (HBOT)
Hyperbaric Oxygen Therapy involves breathing oxygen inside a pressurised chamber.
The increased pressure allows greater amounts of oxygen to dissolve into the bloodstream and reach body tissues.
HBOT is most commonly used in medical settings and is approved for conditions including:
-
Decompression sickness
-
Carbon monoxide poisoning
-
Certain wound-healing applications
More recently, HBOT has attracted attention within elite sport, where researchers have explored its potential role in recovery, rehabilitation and tissue repair.
A review published in Frontiers in Physiology examined the potential effects of HBOT on exercise performance and recovery under specific conditions. (2)
Limitations of HBOT
Despite its clinical applications, HBOT presents several practical challenges:
-
Sessions can be expensive
-
Specialist facilities are required
-
Treatment protocols are time intensive
-
Access remains limited for many athletes
2. Hyperoxic Training
Hyperoxic training involves breathing oxygen-enriched air while exercising.
Researchers have investigated whether hyperoxia may help:
-
Reduce perceived exertion
-
Support higher training intensities
-
Influence repeated high-intensity performance
-
Improve exercise tolerance under certain conditions
Some studies have reported promising results, particularly within controlled training environments. (3)
Limitations of Hyperoxic Training
Hyperoxic training can be useful in specific settings, but it also presents practical barriers:
-
Specialist equipment is required
-
Controlled environments are often necessary
-
Sessions can be difficult to replicate outside performance facilities
3. Exercise With Oxygen Therapy (EWOT)
Exercise With Oxygen Therapy, commonly known as EWOT, combines physical activity with oxygen inhalation.
Athletes exercise while breathing oxygen-enriched air with the aim of increasing oxygen exposure during movement.
EWOT has gained popularity within wellness and performance communities because it attempts to combine exercise and oxygen delivery simultaneously.
Limitations of EWOT
EWOT still requires:
-
Dedicated equipment
-
Setup time
-
Structured sessions
-
Ongoing access to oxygen systems
For many athletes, these practical considerations can limit long-term adherence.
4. Oxygen-Enriched Hydration: A Different Approach
One of the biggest challenges with oxygen-based interventions is practicality.
HBOT requires specialist chambers.
Hyperoxic training requires dedicated equipment.
EWOT requires oxygen systems and structured sessions.
While these approaches may have value in specific settings, they can be difficult to integrate consistently into everyday training routines.
This is the challenge KURE was created to address.
KURE is an oxygen-enriched spring water designed to fit naturally into training, recovery and active lifestyles. (4)
Rather than requiring specialist facilities, appointments or equipment, KURE incorporates oxygen support into a behaviour athletes already perform every day: hydration.
This creates a fundamentally different proposition.
The goal is not to maximise oxygen exposure during a single session.
The goal is to provide athletes with a practical way to incorporate oxygen-supported hydration into an existing routine.
KURE can be used:
-
Before training
-
During training
-
After training
-
As part of everyday hydration habits
Research Into Oxygen-Enriched Hydration
As interest in oxygen support continues to grow, researchers have also begun exploring whether oxygen-enriched hydration may influence physiological responses during exercise.
A randomised, double-blind, placebo-controlled crossover study conducted by researchers at the University of Roehampton investigated the effects of KURE during steady-state aerobic exercise in trained female athletes.
Researchers observed:
-
Lower blood lactate concentrations during exercise
-
Lower carbohydrate oxidation at specific time points
-
Lower respiratory exchange ratio (RER)
-
Differences in fat oxidation during exercise
The researchers concluded:
"Acute oxygenated water ingestion altered selected metabolic responses during steady-state exercise."
Rather than measuring race performance or time-to-exhaustion outcomes, the study focused on how oxygenated water influenced selected metabolic responses during exercise.
Research conducted by London South Bank University has also explored KURE's effects on hydration and recovery-related markers.
Researchers reported:
-
Lower post-exercise lactate levels
-
Increased tissue oxygenation
-
Improvements in hydration status
-
Faster blood pressure recovery following exercise
While further research is required, these findings have contributed to growing interest in oxygen-supported hydration within performance and recovery discussions.
The Missing Piece: Why Practicality Matters
When athletes evaluate recovery strategies, the conversation often focuses on effectiveness.
But there is another factor that may be just as important:
Consistency.
The challenge with many oxygen-based interventions is not necessarily whether they work under specific conditions.
The challenge is whether athletes can realistically use them often enough to become part of their routine.
Performance is rarely built through isolated interventions.
It is built through habits.
Athletes improve because they consistently:
-
Train
-
Recover
-
Hydrate
-
Sleep
-
Refuel
-
Repeat
This philosophy sits at the heart of KURE's approach.
Rather than creating another specialist recovery intervention, KURE was developed around a simple idea:
Oxygen support should be easy to incorporate into habits athletes already perform every day. (4)
Comparing Oxygen-Based Approaches
These approaches are not necessarily direct alternatives to one another.
Many athletes use multiple recovery and performance strategies simultaneously depending on their goals, training environment and access to facilities.
The key difference is often not effectiveness, but practicality, frequency of use and how easily each approach fits into an athlete's routine.
Where Does KURE Fit Within Oxygen-Based Recovery Strategies?
Elite athletes often have access to:
-
Recovery clinics
-
Sports science teams
-
Recovery technologies
-
Physiotherapy support
-
Specialist performance facilities
Yet the foundations of performance remain remarkably simple:
-
Hydration
-
Nutrition
-
Sleep
-
Intelligent training management
-
Consistent recovery habits
KURE is designed to sit alongside these foundations.
It is not an oxygen therapy or medical treatment.
It is an oxygen-enriched spring water designed to integrate naturally into everyday training, recovery and active lifestyles. (4)
For athletes, the appeal is straightforward.
No appointments.
No specialist equipment.
No dedicated recovery sessions.
Just a practical hydration product that fits naturally into routines athletes already perform every day.
This reflects KURE's philosophy:
Perform. Recover. Repeat.
FAQs About Oxygen and Performance
Does oxygen help recovery after exercise?
Oxygen plays an important role in recovery-related processes after exercise, including energy restoration and metabolic regulation. Some oxygen-based strategies have been studied for their potential impact on recovery markers, but outcomes vary depending on the intervention and context.
What is oxygenated water?
Oxygenated water is water that contains added oxygen. In the context of performance and recovery, oxygen-enriched hydration is designed to provide a practical way to incorporate oxygen support into everyday hydration habits.
Is oxygen water the same as oxygen therapy?
No. Oxygen water is not the same as medical oxygen therapy. KURE is an oxygen-enriched spring water, not an oxygen therapy or medical treatment. (4)
What is the difference between HBOT and EWOT?
HBOT involves breathing oxygen inside a pressurised chamber. EWOT involves exercising while breathing oxygen-enriched air. Both use inhaled oxygen, but they differ significantly in intensity, setting and practical use.

Conclusion
Oxygen remains one of the most important factors influencing exercise performance, energy production and recovery.
Researchers continue to explore how different oxygen-based interventions may affect athletic performance, training adaptation and recovery dynamics.
Approaches such as Hyperbaric Oxygen Therapy, hyperoxic training and EWOT can provide meaningful increases in oxygen exposure.
However, they often require specialist equipment, dedicated facilities or significant time commitments.
KURE was developed around a different idea.
Rather than focusing on maximum oxygen exposure, it focuses on practicality and repeatability.
Designed to fit naturally into everyday training and recovery routines, KURE provides athletes with a simple way to incorporate oxygen-enriched hydration into habits they already perform consistently.
As research into oxygen-supported hydration continues to evolve, the opportunity may not lie in replacing more intensive oxygen interventions.
Instead, it may lie in making oxygen support more accessible, practical and repeatable.
Because ultimately, long-term performance is rarely built on what works once.
It is built on what athletes can consistently repeat over time.
