Could training with less oxygen help you prepare for your next race? Discover how simulated altitude training works, why athletes use it and what to consider before getting started.
Whether you're training for a marathon, HYROX, a triathlon or your next cycling event, you're always looking for ways to improve.
One method athletes explore is altitude training.
Traditionally, this means travelling to the mountains to train where less oxygen is available. Today, specialist equipment can create a similar low-oxygen environment without leaving your home or training facility.
But how does it work? Can it improve your fitness? And is it worth considering as part of your training plan?
Let's take a closer look.
1. What is altitude training?
At sea level, the air around us contains about 21% oxygen.
At high altitude, air pressure is lower. This means less oxygen is available with each breath, making exercise feel harder.
Your body must work to deliver enough oxygen to your muscles as you move.
Simulated altitude training uses specialist equipment to create air with a lower oxygen concentration. A hypoxic generator supplies this air through a compatible breathing mask while you exercise.
This allows athletes to explore training in reduced oxygen without travelling to a high-altitude location.
2. How Does Exercising With Less Oxygen Work?
Your muscles need oxygen to help produce the energy required for exercise.
When you train in a reduced-oxygen environment, delivering oxygen to your muscles becomes more challenging. Your breathing, heart rate and sense of effort may change, even if you maintain the same exercise workload.
Over time, the body may respond to repeated exposure in different ways. However, these responses depend on the person, the training method and the amount of exposure.
This is why altitude training needs a clear plan. Simply making a workout feel harder does not guarantee better results.
3. What is a hypoxic generator and training mask?
A hypoxic generator is a machine that produces air with a lower oxygen concentration than normal room air.
The generator connects to a specialist breathing mask through a tube. While you exercise, the system delivers reduced-oxygen air to the mask.
Depending on the equipment and the training plan, this setup may be used with activities such as treadmill running, stationary cycling or other suitable exercise.
There is an important difference between this equipment and the common training masks sold in gyms.
A standard resistance mask makes breathing harder by restricting airflow. It does not create the same reduced-oxygen environment as a hypoxic generator.
If your goal is to explore simulated altitude training, the type of equipment matters.
4. How Do Athletes Use Altitude Training?
Athletes use altitude training in different ways. The approach depends on their sport, goals and access to altitude-training facilities.
Live High, Train High
Athletes live and train at altitude. They experience lower oxygen availability throughout the day, including during exercise.
However, high-intensity training can become more difficult when less oxygen is available.
Live High, Train Low
Athletes spend time living or sleeping at altitude but return to lower altitude for key training sessions.
The aim is to gain possible benefits from longer altitude exposure while maintaining training quality at lower altitude. This approach has been studied in endurance sports.
Live Low, Train High
Athletes live at normal altitude but use simulated altitude equipment for selected exercise sessions.
A hypoxic generator supplies reduced-oxygen air through a compatible mask while the athlete runs, cycles or performs another suitable workout.
This allows athletes to explore hypoxic exercise without travelling to the mountains.
Can Athletes Alternate Between Normal and Reduced Oxygen?
Yes. Some training protocols alternate between normal and reduced-oxygen exposure, either during a session or across different sessions.
However, these methods are not interchangeable. Short periods of hypoxic exercise do not automatically produce the same adaptations as spending many hours at altitude.
Research results vary, and the benefits depend on the protocol and the athlete. Simulated altitude training should therefore be treated as a possible addition to a structured programme, not a guaranteed route to better performance.
5. Why Do Athletes Explore Altitude Training?
Athletes explore altitude training for different reasons, often as part of a wider performance plan.
Endurance and Aerobic Fitness
Runners, cyclists and triathletes rely on their ability to keep moving over long periods.
Some athletes explore hypoxic training to see whether it can support their endurance programme. However, improvements are not guaranteed, and research results vary between methods and individuals.
Race Preparation
If you're preparing for a marathon, triathlon or HYROX event, you may be interested in different ways to structure your training.
Simulated altitude training is one option to investigate, but it should fit around your existing plan rather than replace the sessions that matter most for your event.
Training Variety
Some athletes like to explore different training methods as they work towards a specific goal.
Hypoxic exercise provides a different challenge from normal training. But a harder session is not automatically a more effective one.
The important question is whether the method adds value to your programme, not simply whether it feels more difficult.
6. Can Altitude Training Improve Your VO₂ Max?
VO₂ max measures the maximum amount of oxygen your body can use during intense exercise. It is one measure of aerobic fitness.
A higher VO₂ max can be useful for endurance athletes, but it is only one part of performance. Your pace, power, movement efficiency, lactate threshold and ability to sustain effort also matter.
Some athletes explore altitude training to support their endurance training and performance goals. However, results depend on the method used.
Living or sleeping at altitude, exercising at real altitude and exercising with a hypoxic generator are different approaches. Research findings from one method cannot automatically be applied to another.
The honest answer: simulated altitude training may be worth exploring for some athletes, but it does not guarantee an increase in VO₂ max, faster race times or improved endurance.
Consistent training, suitable recovery, good nutrition and sufficient sleep remain the foundations of performance.
7. Is Altitude Training Suitable for HYROX, Running and Cycling?
Different sports place different demands on the body, so the role of altitude training may also differ.
Runners may be interested in how hypoxic exercise fits into their aerobic and interval training.
Cyclists may explore it alongside steady rides, structured intervals and power-based training.
HYROX athletes combine running with demanding functional exercises. They may be interested in how hypoxic exposure fits into their wider conditioning plan.
In every case, the priority should be to maintain the quality of the training programme.
If reduced oxygen causes you to lose control of your pace, technique or workload, the session may no longer serve its intended purpose.
Hypoxic training should be planned around your current fitness and goals, with suitable professional guidance.
8. How Should You Approach Training With Reduced Oxygen?
Training with a hypoxic generator is not something to approach by guesswork.
Before starting, consider the following:
-
Know your goal. Be clear about what you want to achieve and how the method fits into your training plan.
-
Understand the equipment. Learn how the generator and mask work, including their settings and limits.
-
Follow a suitable protocol. Exposure levels, session length and training intensity should be chosen with qualified guidance.
-
Monitor your response. Reduced oxygen can affect how you feel and how your body responds during exercise. Follow the monitoring and safety procedures recommended for your equipment.
-
Do not push through warning signs. Stop if you experience concerning symptoms and seek appropriate medical advice.
-
Check medical suitability. If you have a health condition or are unsure whether hypoxic exercise is suitable for you, consult a qualified healthcare professional first.
There is no single protocol that is right for everyone. More exposure is not necessarily better, and a training method should never come at the cost of your health or the quality of your overall programme.
9. Is Simulated Altitude Training Worth Exploring?
That depends on your goals, training history and expectations.
If you're already following a structured programme and want to understand more about hypoxic training, a generator and exercise mask offer a way to explore reduced-oxygen exercise without travelling to a high-altitude location.
Before committing, make sure you understand the equipment, the evidence behind your intended use and the practical requirements.
It is also worth remembering that simulated altitude training is not the same as preparing for the medical challenges of a real high-altitude expedition. It should not be relied upon to prevent altitude sickness.
For most athletes, the foundations remain the same: consistent training, sensible progression, good recovery and a clear goal.
Altitude training is an option to investigate, not a shortcut around those fundamentals.
