Its symptoms include headaches, nausea, fatigue, and dizziness, among others. This occurs because, at high altitudes, the thinner air contains less oxygen, making it harder for your body to function optimally if you are not adapted to it.

As you ascend to higher altitudes, the lower air pressure leads to an accumulation of CO2 in your bloodstream. This can trigger symptoms and exacerbate the effects of low oxygen, causing discomfort and distress. So, how does CO2 tolerance training come into play, and why is it crucial for high-altitude adventures?

CO2 tolerance training involves controlled breathwork techniques that help you build a higher threshold for CO2 buildup in your system. It enables your body to better tolerate elevated CO2 levels and facilitates the uptake of precious oxygen, ensuring that your muscles and brain receive the oxygen they need to function optimally.

Breathwork and CO2 tolerance training also contribute significantly to mental preparation. High-altitude environments can be physically and mentally taxing. By practicing controlled breathing, you can reduce stress and anxiety, which are common psychological challenges at high altitudes.

Calming the mind through breathwork can improve decision-making and overall emotional well-being. Oxygen Advantage is a leader in the field of breathing practices for altitude, and we recommend taking a look at their courses and products in advance of your adventure. This technique enhances CO2 tolerance while promoting efficient oxygen exchange.

Breath-holding exercises challenge your CO2 tolerance and help your body adapt to lower oxygen levels.

This modified box breathing technique places a strong emphasis on extended exhalations, which aids in expelling excess CO2 from your system. Gradual ascent and consistent breathwork training go hand in hand to enhance your high-altitude experience.

Breathwork during acclimatization ensures that your body and mind remain in sync with the changing environment. In addition to breathwork, physical and mental preparations are essential components of your high-altitude journey:.

The CO2 Tolerance Connection. Improved Oxygen Uptake: CO2 tolerance training involves controlled breathwork techniques that help you build a higher threshold for CO2 buildup in your system.

Reduced Stress and Anxiety: Breathwork and CO2 tolerance training also contribute significantly to mental preparation.

CO2 Tolerance Training Techniques. Here are a few other options:. Controlled Nose Breathing: Focus on breathing through your nose rather than your mouth. Inhale deeply through your nose for a count of four. Even getting used to breathing in a rhythm, taking deep, abdominal breaths, can help.

The more you understand about how to get in under control, the less panicked you may feel on the trek if it does happen. At altitude you should be drinking water more frequently than you would normally, no matter what activity you are undertaking.

Humidity is lower at higher altitudes, which means that sweat evaporates quickly and often without you noticing. Lower oxygen levels also make you breathe in and out faster, so you lose more water through respiration — sometimes twice as fast than at sea level.

Another effect of altitude sickness is the need to urinate more. All this means you need to drink much more as dehydration can mask or worsen the symptoms of altitude sickness.

It's important to check your travel insurance will cover you for the altitude you will be walking at. This doesn't always come as standard. Check the trip dossier to see your maximum altitude. If you are ascending rapidly to a starting point that is at altitude driving or flying you should spend a couple of days at your destination doing very little.

Don't over exert yourself and get used to moving at altitude. Doing this will greatly improve your condition on the trek. Part of the experience of your high altitude trek will be trying the local measures to combat the altitude alongside your careful preparation.

In the Andes they chew coca leaves and drink coca tea and in the Himalayas they eat chhurpi, a dried yak cheese. Many people experience symptoms of altitude sickness and in its milder forms it can cause breathlessness, headaches and nosebleeds.

Much more serious are the symptoms such as a cough, persistent severe headaches, nausea, loss of coordination and disorientation. You should tell your guide at any point if you feel unwell. The only measure to stop the sickness progressing is to stop at your current altitude and you may need to descend if the symptoms don't improve over a day.

Travel, experience, conserve with. Check with a doctor Speak to your doctor before you start a new training regime to ensure you have no pre-existing conditions that will stop you from walking at high altitude.

Aerobic training Your preparation should include a good amount of cardio at a sustained level to improve your aerobic fitness. Slowly increase the distance and altitude of any training treks Although it may be hard to increase the altitude of your training treks especially if you are training in Great Britain , you should increase the distance and time you walk as you train.

Learn yoga breathing rhythms At high altitude you may find yourself breathless after just a small burst of exertion. Get used to drinking a large amount of water At altitude you should be drinking water more frequently than you would normally, no matter what activity you are undertaking.

Insurance It's important to check your travel insurance will cover you for the altitude you will be walking at. Spend time acclimatising If you are ascending rapidly to a starting point that is at altitude driving or flying you should spend a couple of days at your destination doing very little.

Such simulated altitude systems can be utilized closer to competition if necessary. In Finland , a scientist named Heikki Rusko has designed a "high-altitude house. Athletes live and sleep inside the house, but perform their training outside at normal oxygen concentrations at Rusko's results show improvements of EPO and red-cell levels.

Artificial altitude can also be used for hypoxic exercise, where athletes train in an altitude simulator which mimics the conditions a high altitude environment. Athletes are able to perform high intensity training at lower velocities and thus produce less stress on the musculoskeletal system.

Hypoxia exposure for the time of exercise alone is not sufficient to induce changes in hematologic parameters.

Hematocrit and hemoglobin concentrations remain in general unchanged. who pioneered the artificial altitude training systems in the mids. A South African scientist named Neil Stacey has proposed the opposite approach, using oxygen enrichment to provide a training environment with an oxygen partial pressure even higher than at sea level.

This method is intended to increase training intensity. Altitude training works because of the difference in atmospheric pressure between sea level and high altitude. At sea level, air is denser and there are more molecules of gas per litre of air.

As the altitude increases, the pressure exerted by these gases decreases. Therefore, there are fewer molecules per unit volume: this causes a decrease in partial pressures of gases in the body, which elicits a variety of physiological changes in the body that occur at high altitude.

The physiological adaptation that is mainly responsible for the performance gains achieved from altitude training, is a subject of discussion among researchers. Some, including American researchers Ben Levine and Jim Stray-Gundersen, claim it is primarily the increased red blood cell volume.

Others, including Australian researcher Chris Gore, and New Zealand researcher Will Hopkins, dispute this and instead claim the gains are primarily a result of other adaptions such as a switch to a more economic mode of oxygen utilization.

At high altitudes, there is a decrease in oxygen hemoglobin saturation. This hypoxic condition causes hypoxia-inducible factor 1 HIF1 to become stable and stimulates the production of erythropoietin EPO , a hormone secreted by the kidneys , [24] EPO stimulates red blood cell production from bone marrow in order to increase hemoglobin saturation and oxygen delivery.

Some athletes demonstrate a strong red blood cell response to altitude while others see little or no gain in red cell mass with chronic exposure. While EPO occurs naturally in the body, it is also made synthetically to help treat patients with kidney failure and to treat patients during chemotherapy.

Over the past thirty years, EPO has become frequently abused by competitive athletes through blood doping and injections in order to gain advantages in endurance events.

Abuse of EPO, however, increases RBC counts beyond normal levels polycythemia and increases the viscosity of blood, possibly leading to hypertension and increasing the likelihood of a blood clot , heart attack or stroke.

The natural secretion of EPO by the human kidneys can be increased by altitude training, but the body has limits on the amount of natural EPO that it will secrete, thus avoiding the harmful side effects of the illegal doping procedures. Other mechanisms have been proposed to explain the utility of altitude training.

Not all studies show a statistically significant increase in red blood cells from altitude training. One study explained the success by increasing the intensity of the training due to increased heart and respiration rate. Another set of researchers claim that altitude training stimulates a more efficient use of oxygen by the muscles.

In a study comparing rats active at high altitude versus rats active at sea level, with two sedentary control groups, it was observed that muscle fiber types changed according to homeostatic challenges which led to an increased metabolic efficiency during the beta oxidative cycle and citric acid cycle , showing an increased utilization of ATP for aerobic performance.

Due to the lower atmospheric pressure at high altitudes, the air pressure within the breathing system must be lower than it would be at low altitudes in order for inhalation to occur. Therefore, inhalation at high altitudes typically involves a relatively greater lowering of the thoracic diaphragm than at low altitudes.

When preparing for a high altitude trek, you must consider the physical toll the trek will take on your body. Weight, aerobic fitness, and overall strength will all factor into how your body responds to the large demands of trekking at altitude.

Strength training will help prepare your leg muscles and upper body for shouldering a heavy load, as will core exercises. Aerobic activity is another key component for preparing your body for high altitude adventures. While running and hiking might be the closest approximation to your eventual trek activities, there are other options too.

Swimming or biking can also be great ways to condition your body for those long days on the mountain. Of course, the best aerobic preparation would be training in similar conditions that you will encounter on your trek; ideally you can find mountain trails and hike with a backpack carrying build up the weight you carry from 10lbs to possible 25lbs.

We can help you develop a plan for your specific trip. One of the key components for preparing for high altitude is hill training.

Whether or not you can train at altitude, hill training should be a central part of your exercise plan. Therefore, hill intervals or steep hikes are so important to your preparation.

Why not try running stadiums at your local school or climbing the stair-master at the gym. It might feel repetitive, but hill training exercises will not only prepare your muscles for the trek but will also help to improve your VO2 max — helping you function better at altitude.

It will help your body become accustomed to trekking and mountain climbing. For those with a history of acute mountain illness or undertaking a trek with a faster than recommended ascent rate, it could be prudent to consider asking a physician about taking a prophylactic medication such as acetazolamide.

These medications can reduce the risk of developing an acute mountain illness, or reduce the severity of symptoms. A high altitude adventure is an incredibly demanding but equally fulfilling undertaking. Understanding the potential risks and preparing to the best of your ability will put you on the right track for having a safe and successful trek.

There will be no substitute for hours training. It is important to build slowly over months of preparation. You need to build up the weight you carry and hours of training per week. This will vary for trip to trip.

It is best to contact us and we can guide you on training for the specific trip you are planning. Just as important as leg strength and specific endurance training, your lungs need to be trained as well.

So training in specific heart zones and time and hours spent in these correct zones is extremely important as you build your training to be as efficient as possible. There you have it.

Yes, it is easier to get these adaptations by living at altitude—just not practical. Let us help you gather all the information you need to be safe and successful. We hope this post on how do you train for High Altitude and Low Oxygen Environments was useful.
