4 Common Misconceptions about Altitude Training

Altitude training has been around for a while – ever since the 1968 Mexico Olympics. Despite its long history, it remains relatively unknown, especially here in North America. This is because altitude training has been used only exclusively by the pros. Only recently has the technology become more accessible to everyday athletes. Because of how elusive it is, we have come across some misconceptions about altitude training. Here are 4 of the most common ones we’ve heard:

1. It’s only for people who are planning to race at altitude

No, altitude training is not just for people competing at altitude. It’s also for people looking to improve their athletic performance at sea level, specifically increase their VO2 max, aerobic capacity and power output.

Look at it like resistance training, but for your endurance. Reducing the oxygen percentage in the room is like adding resistance to your workout. And building that kind of training into your program will improve (or at the very least, maintain) performance at any elevation.

2. Altitude training is dangerous

We commonly get the question – “Is altitude training safe? There are risks associated with any form of physical activity – whether it be hot yoga, a high intensity spin class, or a run around the neighborhood. The same goes for training in a simulated altitude environment. To reduce risk as much as possible – members are assessed and screened before entering the altitude room. During training, members are given carefully regulated programs based on their conditioning. Additionally, members are always under supervision from trained coaches. Heart rate monitors and pulse oximeters are used regularly to monitor exertion.

Of course, not all forms of exercise are safe for everybody. And altitude training isn’t recommended for people who are pregnant, have breathing problems like asthma, have high blood pressure or other serious medical issues.

3. But I’ll lose strength and power exercising at altitude

Training in reduced oxygen typically means you are unable to reach the same levels of ‘intensity’ as you can at sea level. It is this stress of hypoxia on the body that stimulates it to be more efficient in using oxygen and providing energy to active muscles, improving aerobic conditioning and endurance. Continuous exposure to high altitude will cause you to lose power. But, when you combine simulated altitude training sessions (2-3 per week) with your regular strength and power sessions at sea level – you can maintain, and actually boost, your strength and power levels no problem.

4. I’ve heard that you are supposed to sleep in an altitude tent. Why exercise?

Altitude tents are designed for the “live high, train low” model. This method of training (sleeping at altitude) is commonly used by athletes to increase their red blood cell count and improve overall performance.

For those of us living at sea level, and who aren’t professional athletes – altitude tents can become impractical. We don’t have the benefit of naturally ‘living high’ and it can be hard to get the most out of an altitude tent – which you should be using for 4 weeks, 16 hours/day while maintaining training. See here.

A great alternative is simulated altitude training, which follows the “live low, train high” model. You already live low, and perhaps mostly compete low. Training high gets the job done quicker (2-3 sessions per week is usually recommended) and it’s much easier to convince your partner about heading to the gym than sleeping in a tent.

Altitude Training for General Health and Fitness: 3 Case Studies to Read

The recent literature on Intermittent Hypoxic Training (IHT) shows benefits that go beyond high performance for athletes. Indeed, we see benefits that extend to your average gym-goer training for improved fitness, overall health and disease prevention.

Today we’ll highlight some case studies that show the impact of hypoxic training on general health and fitness populations. The results are also helpful in comparing the outcomes of training at altitude vs. sea-level.

Altitude Training Benefits: Case Studies

1. Effects of systemic hypoxia on human muscular adaptations to resistance exercise training

Oxygen Level (%): 14.4%

Equivalent Elevation (m): 3000 m

Methods: Subjects performed resistance training 2x/week for 8 weeks

Results: IHT resistance training improved cross sectional area of muscles (muscle size), strength and muscular endurance and increased formation of capillaries (improved blood flow) to muscles. In comparison to sea-level training, a greater effect was seen specifically on muscular endurance and capillary density.

Summary:

  • Hypoxic training improved muscular endurance more than the same training sea-level
  • Hypoxic training increased capillary density more than sea-level training
  • Capillary density is important for delivery of blood and oxygen and removal of waste by-products from working tissues.

2. Effects of strength training under hypoxic conditions on muscle performance, body composition and haematological variables

Oxygen Level (%): 13.0%

Equivalent Elevation (m): 4000 m

Methods: Participants trained 3 days per week for 7 weeks (3 sets x 65−80% 1RM to failure).

Results: Both groups improved their strength performance and muscle perimeters, but the hypoxia group obtained a greater increase in muscle mass (hypoxia: +1.80% vs. normoxia: +0.38%; p<0.05) and decrease in fat mass (hypoxia: -6.83% vs. normoxia: +1.26%; p<0.05) compared to the normoxia group. Additionally, haematocrit values were also higher for the hypoxia group after the detraining period (hypoxia: +2.20% vs. normoxia: -2.22%; p<0.05).

Summary:

  • Hypoxic group had greater gains in muscle mass and greater decreases in fat mass.
  • For individuals seeking improved health and body composition, hypoxic training can increase muscle mass and decrease fat mass more effectively than normoxic training

3. The Effects of Aerobic Exercise at Hypoxic Condition during 6 Weeks on Body Composition, Blood Pressure, Arterial Stiffness, and Blood Lipid Level in Obese Women

Oxygen Level (%): 16.5% & 14.5%

Equivalent Elevation (m): 2000 m & 3000 m

Methods:

Subjects: Women, 30-55 years old, BMI > 30 and BF% > 30

Participants were divided into three groups: Sea-level (normoxic), 16.5% O2 (2000 m) moderate altitude, 14.5% O2 (3000 m) high altitude

Participants performed 30 minutes on the treadmill followed by 30 minutes on the bike, 5 times per week for 6 weeks

Results: Both hypoxic groups saw a larger reduction rate of fat mass and % body fat vs. the normoxic group. The 14.5% O2 group saw the most significant decrease in body weight.

Systolic blood pressure significantly improved in both hypoxic groups. Diastolic blood pressure improved in all groups, but more so in both hypoxic groups.

All groups had improvements in LDL (low-density lipoprotein, sometimes called “bad” cholesterol because it collects in the walls of your blood vessels, raising your chances of health problems). Hypoxic training groups improved more than the normoxic group.

Both hypoxic groups showed greater improvements in arterial stiffness compared to the normoxic group.

Summary:

  • Greater improvements in heart rate, blood pressure, cholesterol arterial stiffness and weight loss with hypoxic training compared to normoxic training
  • Both hypoxic groups saw a larger reduction rate of fat mass and % body fat vs. the normoxic group
  • Greater health benefits can be achieved with a lower exercise intensity at simulated altitude compared to sea-level training in overweight individuals

How difficult is the hike to Machu Picchu?

By this point, you’ve likely scrolled past your fair share of social media pics backdropped by the mysterious Peruvian city in the sky—aunts and uncles communing with shaggy llamas, friends clambering up dirt paths, workmates teetering on a stone outcropping, peering down at the ancient city.

Machu Picchu is one of the most visited tourism destinations in the world. On average, it attracts close to 1.2 million visitors a year and was voted one of the new seven wonders of the world in 2007. The site has become so popular that the Peruvian Ministry of Culture, in an attempt to preserve the site, has had to set a limit of 2,500 tourists entering the citadel a day.

The site’s popularity, however, significantly underplays the effort it takes to get there. At nearly 8,000 ft. above sea level, Machu Picchu is perched amongst one of Peru’s highest mountain ranges. Meaning whichever route you take to reach the Inca Citadel, you’ll have to deal with some major altitude adjustments.

Before embarking on your Inca adventure, check out these potential pitfalls to ensure you’re prepared for the trip.

Feeling funny?

The most pressing concern when ascending to high altitude—defined as any height above 8,000 ft.—is altitude sickness. This occurs when the body doesn’t have enough time to adapt to decreased air pressure and oxygen levels. Symptoms include dizziness, fatigue, shortness of breath, and loss of appetite.

While not everyone who hikes to Machu Picchu will be afflicted by altitude sickness, those who are may see their Inca adventure come to an abrupt end. To prevent this from happening, take Diamox one to two days before starting your hike. The medication helps reduce symptoms and eases the adjustment to altitude.

It’s also a good idea to take the hike slow. Your body needs time to acclimatize to the altitude. To help with the acclimatization process and to make sure you have enough energy, keep yourself well hydrated and fed throughout the hike. The porters cooking your meals should help with this, but it’s still a good idea to throw a hydration pack in your bag and some high calorie snacks.

If you do start to experience symptoms, stop and rest for at least a day. If they don’t go away, it might be time for you to turn around.

Choose a trail, any trail

There are many ways to get to Machu Picchu. The most popular is the Inca Trail, a four-day, three-night hike through lush cloud forests, ancient Inca ruins, and majestic Andean peaks. In 2002, however, the Peruvian Ministry of Culture introduced permits for the trail, limiting the number of people to 500 a day (approximately 300 of those permits are allocated to cooks, porters, and guides, leaving only 200 for tourists).

To hike the Inca Trail, you have to book it months in advance. It isn’t a particularly long hike, spanning only 40 kilometres, but it is straight up some steep Andean paths. The trail hits its peak at Dead Woman’s Pass (named after the crests that resemble a woman’s supine body) standing 13,828 ft. above sea level.

If you weren’t able to secure a permit, don’t worry. There are other options. The Salcantay Route is much easier to book and just as scenic. Taking anywhere between five to eight days, this mule-assisted hike passes by the 20,500 ft. Mount Salcanty, one of the most sacred peaks in Inca religion.

You pass Mount Salcanty at an altitude of 15,000 ft. before plunging into a subtropical cloud forest, eventually passing the ancient Incan ruins of Llactapata, nearly as rewarding a sight as Machu Picchu.

If you’re looking for a more moderate hike—one that involves a train—try The Lares Route. Taking between three to five days, this trek leads you through the Lares Valley, home to Peruvian locals who still practice Inca traditions like raising herds of llamas and weaving cloth. Along the way, you pass by the 18,000 ft. Mount Veronica and a number of high-altitude Lakes. The trail ends near the Ollantaytambo ruins, only a short train ride away from Machu Picchu.

Dress for the weather…all of it

The higher you ascend, the more the air pressure decreases and the further apart the air molecules spread, causing the temperature to drop. Yet, in the case of Machu Picchu, you may also experience a scorching midday sun that has you sweating through your jacket. To deal with the swings in temperature, wear layers. This way you can shed them as you hike.

When you book your trip, be wary of the time of year. End of November to beginning of April is Peru’s rainy season. Many of the trails are closed between these months, but in case you do manage to book a hike during this time of year, bring a waterproof rain jacket and tent fly. You never know when you might get caught in a downpour. Starting each morning’s hike soaking wet is a surefire way to catch a cold.

Get in shape!

This one should be obvious, but if you’re going to attempt a four-day hike at high altitude make sure you’re physically prepared. You don’t want to be the person gasping for breath after the first couple hours. Not only will it ruin the experience but it will hold back the group.

In order to prepare for the hike, focus on cardio exercises like running, walking, and swimming. Try to introduce these exercises into your daily routine a few months before your trip. And if you really want to be prepared, come in for a workout at Altitude Athletic Training in Toronto.

 

We can help make sure you’re training effectively to resist fatigue and maintain high energy on your trek. Exposure to the altitude environment will help you pre-acclimate to reduce and prevent symptoms of altitude sickness. You can find some more benefits here: Hiking, Climbing and Mountaineering. Machu Picchu will feel like a walk in the park after working out with us.

Altitude for Rehab and Re-conditioning

Why altitude training will help your clients get better results during rehab?

Most of us expect to lose some level of conditioning when we get injured. But that doesn’t have to be the case.

Altitude training for sports rehab can be used to create a stimulus that maximizes aerobic output, while reducing training intensity and load on recovering tissue.

Therefore, sessions at simulated altitude (i.e a walk on the treadmill in a simulated altitude chamber or a spin on the bike with an altitude mask) can be done at lower intensities with greater benefit and help recovering clients maintain cardiovascular fitness while injured.

The goal is to mitigate the de-conditioning effect and accelerate the re-conditioning process, providing maximum aerobic adaptations during recovery.

Injuries are never easy, but with intelligent program design and training, clients can get back to full fitness faster and stronger than before.

Minimize De-conditioning, Maximize Re-conditioning

Altitude Athletic can facilitate the return-to-fitness process using specific altitude protocols designed to maintain cardiovascular fitness during injury.

Protocols can be either passive (Intermittent Hypoxic Breathing*) or active and built for varying levels of exercise tolerance.

*Intermittent Hypoxic Breathing (IHB) consists of breathing very low oxygen air from a stationary position (seated) in a series of intervals interspersed with sea-level breathing.

altitude training for sports rehab

Altitude Training for Sports Rehab: Training Recommendations

  • “My client is recovering from an injury and can still exercise.”

If you have a client who can still train actively, use an active intermittent hypoxic training protocol.

For instance, a protocol that has been used for this scenario is 30 minutes of continuous aerobic exercise as close to 75% of max heart rate as possible at 14.5% O2. The goal is to ease the client into a reconditioning program that still elicits a greater performance adaptation. Therefore, reconditioning is more effective and faster than it would have been at sea level.

  • “My client is recovering from an injury and cannot tolerate exercise.”

If your client is struggles to exercise – for example an elderly individual or someone with cardiovascular disease – use a passive breathing protocol. These protocols are based on a tolerance test, for example: 4-6 rounds, 3-5 minutes ON 3-5 minutes OFF at 14.5%-10% O2.

With severely de-conditioned individuals, passive exposures can increase fitness level, aerobic capacity, exercise tolerance, performance and quality of life. Passive exposures can also offset some level of de-conditioning.

Opportunities for Physios and Clinics

By building altitude training into your client’s rehabilitation, you now have a solution to minimize unnecessary de-conditioning and maximize re-coniditioning at the acute and post-injury stages. The result is happier clients, better results achieved faster and greater success for your practice.

You’ve also opened the door to populations with low-exercise tolerance who previously had few solutions for re-conditioning. Intermittent Hypoxic Breathing is game-changing for their health and quality of life. The opportunities provided from this new market will offer a huge boost to your business.

See Results Faster – Why Altitude is Great for the Busy Professional

altitude training for the busy professional

With many of us back to the office – we can no longer be as generous with our lunchtime workouts. If you can squeeze a lunchtime workout in, often it’s less than an hour — which isn’t much if you factor in transit time to the gym and showering after the workout. So, how do you get the most out of your workout in the shortest amount of time and see faster results? Training at altitude presents an ideal solution to this dilemma.

It's What's in the Air That's Different

Efficiency is one of the greatest assets of altitude. Training in an environment with less available oxygen triggers physiological adaptations (changes in the body) that can lead to fitness and performance benefits. And due to the unique demands altitude puts on the body, results can be seen in less time than the same workout at sea-level. Adaptations include: 

  • Increased Mitochondrial Density: Hypoxic conditions stimulate the production and density of mitochondria within muscle cells. Mitochondria are responsible for aerobic energy production. With more mitochondria, muscles can generate energy more efficiently, leading to improved endurance and performance. This efficiency means athletes can achieve the same or greater physical output with less effort and in less time compared to training at sea level.

  • Enhanced Capillary Density: Exposure to hypoxic environments promotes the growth of new capillaries that deliver oxygen-rich blood to muscles. This increase in capillary density enhances oxygen delivery and nutrient exchange, improving muscle endurance and recovery. As a result, athletes can sustain higher-intensity efforts for longer periods without experiencing as much fatigue, ultimately making their workouts more productive in less time.
  • Improved Muscle Buffering Capacity: Muscles adapt to hypoxic stress by improving their ability to buffer and remove metabolic byproducts like lactate. This adaptation delays the onset of muscle fatigue during intense exercise, allowing athletes to maintain higher workloads and intensity levels throughout their training sessions. By reducing the recovery time needed between sets or intervals, athletes can complete more effective workouts in a shorter total time.
  • Enhanced Oxygen Extraction and Utilization: The body becomes more efficient at extracting oxygen from the bloodstream and using it within muscle cells. This efficiency improvement supports higher aerobic capacity and optimizes energy production during exercise. Athletes experience improved stamina and can perform more work per unit of oxygen consumed, maximizing the effectiveness of each training session.
  • Increased Respiratory Efficiency: Training in hypoxic conditions strengthens respiratory muscles and enhances lung function. This improvement in respiratory efficiency allows athletes to breathe more effectively during exercise, taking in more oxygen and expelling carbon dioxide more efficiently. As a result, athletes can sustain higher-intensity efforts for longer periods without becoming as breathless, ultimately improving overall workout efficiency.

You will be working harder at altitude. For instance, your heart rate will be elevated and your cardiovascular, pulmonary and oxygen utilization systems will be working harder to meet the energy demand required with less oxygen available.

Higher Efficiency, Lower Impact

Despite being harder in some aspects, people are often surprised to learn that altitude training is much easier on the joints. You can work at a lower impact with less wear and tear on the body, and get the same if not better benefits than sea-level training in less time.

While commonly praised for its physiological benefits among professional athletes, an adaptive approach to exercising at altitude can enhance anyone’s overall fitness. Efficient in burning more calories during a given amount of time than at sea level, the time-crunched gym-goer can get a great workout completed in as little as 30 minutes — a reasonable amount of time to squeeze in to busy days.

Simulated Altitude Training

This all sounds great – but this whole time you may have been wondering how on earth you are going to get up to altitude if you live in a sea-level city, like Toronto. That’s where simulated altitude training comes in.

Altitude training is exercising in, sleeping in, or simply inhaling the oxygen-reduced air that you find at high altitudes. Simulated altitude gyms are one of the best methods for replicating high altitude conditions at sea-level. Picture a gym that is fully-equipped with treadmills, bikes, squat racks and dumbbells but encased in a high-altitude chamber.

personal training, science and analysis

It's All in The Science

The latest research on simulated altitude training shows greater improvements in body composition, overall fitness and health factors for the same amount of training at sea-level. In one study, participants saw a greater increase in muscle mass with 7 weeks of altitude training compared to participants doing the equivalent sea-level training. The altitude group saw an increase in muscle mass of 1.80% compared to the sea-level group, which saw an increase of just 0.38%. Also, the altitude group saw a significant decrease in fat mass of 6.83% compared to the sea level group, which actually increased their fat mass by 1.26%.  To read the full study, click here.

By leveraging these physiological adaptations through hypoxic training, busy professionals can achieve greater fitness gains and performance improvements in less total workout time. The combination of enhanced energy production, improved endurance, and reduced fatigue translates into more effective training sessions that yield measurable results sooner than traditional sea-level training methods.

Climbing Kilimanjaro? Here’s Why You Should Be Doing Simulated Altitude Training

Kilimanjaro Summit Image

You’ve decided to climb Kilimanjaro. At 5,895 m, you’ll be tackling the tallest mountain in Africa. Are you ready?

Being physically prepared is critical to a successful climb. You want to think back on your trip with fond memories of reaching the summit and feeling good, not turning back early. For most of us, these trips are an expensive, once-in-a-lifetime kind of thing. Having to cut your trip short due to altitude sickness, lack of fitness or both is a shame. Especially because there are tools out there to help prevent that from happening.

 

Simulated Altitude Training for Climbing Kilimanjaro

If you live at sea-level and can’t easily access the mountains, you may want to consider what’s called ‘simulated altitude training’. Simulated altitude training is exercising in or breathing air with less oxygen to replicate the thinner air you find up in the mountains. Simulated altitude is created by decreasing the percentage of oxygen in the air below 20.9% oxygen (the amount of oxygen in the air at sea-level).

From sleeping in an altitude tent to lifting weights at an altitude gym, simulated altitude training methods can be used to get you ready for Kilimanjaro. We break down the two most commonly used methods below:

 

Method 1: Intermittent Hypoxic Training

Intermittent Hypoxic Training (IHT) is living at sea-level and exercising at altitude. If you’ve got a stationary bike or treadmill at home, you can use a simulated altitude training mask to breath hypoxic air while you’re training. Otherwise, there are special gyms that can actually simulate altitude with no masks needed. 

These shorter duration workouts at simulated altitude are designed to provide a greater training intensity. They trigger physiological adaptations that can improve overall health and performance. These adaptations require a minimum training period of 4-6 weeks, 3-4x per week. Sessions should last around 60 minutes.

 
Simulated Altitude Gym – Intermittent Hypoxic Training

Perform Better at High-Altitude

IHT optimizes the body’s ability to use and process the oxygen available to it. Why does that matter to you as a hiker preparing for Kilimanjaro? Because when your muscles and tissues use oxygen more efficiently, you can sustain longer periods of exertion. This becomes especially important when there is less oxygen available to you at high altitudes.

Another good thing about training your body to use oxygen more efficiently? You’ll reduce reliance on supplemental oxygen. Usually, climbers do not need supplemental oxygen to climb Kilimanjaro or reach the summit. But, if you find yourself in a position where you do need it, training at altitude can help extend the life of your oxygen tank.

 

Delay Fatigue and Recover Faster Between Treks

The more you can push away the start of fatigue during your trek, the better. In altitude environments, metabolic by-products associated with fatigue build up quicker with less oxygen available to the muscles. (Think of that burning feeling in your legs during a hard spin class). Training at simulated altitude can reduce and delay the onset of fatigue during physical activity by increasing the buffering capacity of metabolic by-products. We’re essentially making our bodies better at pushing away these fatigue-causing by-products.

 

Method 2: Live High, Train Low

Live high train low (LHTL) is living at high altitudes and training at lower altitudes (close to sea-level). Living in an altitude environment stimulates changes in the blood that can lead to improved performance and help with pre-acclimation.

If you live at sea-level, it’s not easy to just pack up and move out to a place like Flagstaff, Arizona where you can live at 2100m and a short 30-minute commute can get you to 950m. An easier option? Sleep tents and larger altitude tents can be set up at home, so you can get 6+ hours of high-altitude exposure and then be back down to sea-level in seconds. This strategy requires a minimum of 3-4 weeks. However, 6-12 weeks is better so that the altitude can be ramped up slowly.

 

Reduce Risk of Acute Mountain Sickness

LHTL can lower the age of red blood cells and increase hemoglobin mass (hemoglobin is an oxygen-carrying protein). These changes in the blood can help reduce and prevent symptoms of Acute Mountain Sickness (AMS). Also, many people struggle when sleeping at altitude. Fatigue will increase the risk of something going wrong on the mountain. Sleeping at altitude in the weeks leading up to your trip will help your body get used to the reduced oxygen and improve quality of sleep.

 

Final Thoughts

Climbing Kilimanjaro is a physical challenge. Many people underestimate the fitness required for this mountain. (Or say they would have enjoyed the trip more had they been in better shape). Simulated altitude training will not only help you get in shape for the climb, but also prepare you for the altitude. Then, your hard work will be rewarded by a beautiful, peaceful and enjoyable climb.
