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

As the leaves begin to turn and temperatures begin to drop, for many people this time of year becomes staying indoors with Netflix. For the endurance athlete however, the time between November and April can represent a big wide window of opportunity. This is your opportunity to reflect on what went well in your season. You can also identify areas of focus for next season and develop a finely-tuned base-building plan to prep you to conquer the spring.
If your racing season took you into the fall, it’s always a good idea to take a few weeks, or even a couple of months, off of a structured training plan. Physically, this gives your body a true chance to recover. Recovery is needed because prolonged racing and training causes a substantial degree of muscle breakdown and a systemic inflammatory response. It can take up to 19 days after an Ironman-distance triathlon for inflammation and cortisol to return to baseline levels, even in a well-trained athlete. Mentally, endurance events require long term commitment, self-discipline, and a high degree of day-to-day planning and time management. It’s healthy to give yourself a break from the rigidity of this type of schedule.
So once you’ve refreshed your mind and body and as the mornings continue to get darker, here are 5 reasons why you should get yourself back in gear with off-season high altitude training over the colder indoor months.
Controlled environments let you hone in on specific weaknesses.
Did hills eat you up this year? Does your form start to fall apart at a certain speed? Now is the time to work on whatever’s holding you back from the next level. Not having a race schedule allows you to build training blocks and choose training workouts with these goals in mind. Try running or cycling workouts using the treadmills and indoor trainers at Altitude. These workouts can help you work on goals like building aerobic capacity, speed and endurance.
Altitude workouts give you more bang for your buck.
In the altitude chamber, the air contains less oxygen, forcing your body to work harder to meet its oxygen demands. This natural challenge triggers a cascade of physiological adaptations, resulting in increased red blood cell production, enhanced lung capacity, and improved overall endurance. Altitude workouts supercharge your cardiovascular system, making every breath count and maximizing your calorie burn. This is a good thing, since even the strongest mental game can go a little bananas when on a trainer for long periods of time. Which brings us to our next point…
Classes do the job, and they’re social.
Endurance sports can be a little lonely. Maybe you’ve got some friends in the summer that you can join for long runs or rides, but the winter can be much more isolating. Rather than hole up, try a class specifically designed to challenge runners or cyclists at high altitude. Whether you’ve got a friend to go with you or not, the time always passes much more quickly in a group setting, not to mention it’s way more fun. Check out Altitude’s classes here!
Hit March with a spring in your step.
Most athletes look to start racing again for March-April. Nothing feels worse than sitting on your couch for several months, only to blow the dust off of your shoes in spring and have to dedicate the first 6-12 weeks of training to just base build. Even doing a few key workouts per week can keep you from detraining. Or, even better, can help you beef up your base before the warm weather comes around again. You’ll see faster progress and better results with consistent off-season high altitude training.
Keeps the winter blues at bay.
SADS, or seasonal affective disorder syndrome, is a proven disorder that manifests as an increase in sleep, sedentary behavior, depression and sometimes weight gain that occurs during the fall/winter months and remits in the spring. Research has shown that light therapy and getting outside is helpful to combat symptoms, as well as aerobic exercise. Bonus points if you can grab a buddy to join you.
Don’t let the cold winter days get in the way of your progress. Off-season high altitude training can help you build strength and maximize your fitness gains for your next big race.
Training for your first triathlon can be an intimidating experience. From seemingly endless amounts of gear to scarily fast transitions, there can be a lot to wrap your head around leading up to the day. Here are some tips and tricks that will help you feel ready when it’s time to race.
Tip 1: KNOW THE COURSE:
Register for a race close to home, so that you can visit the course before your race to check it out. Take note of the current and terrain; have a sense of how hilly the bike and run will be. Have a sense of what the weather will be like around race day so that you can properly prepare for the appropriate conditions. Prepare at least 12 weeks before your race to give yourself ample time to get ready both mentally and physically.
Try practicing specific course sections you may find tricky; this could be a sharp U-turn on the bike, an uphill climb you are nervous about, or running through a transition zone so you don’t get lost or forget something. After all, transition time counts too and while we’ve all ran with that bike helmet on, it may be easier without!
Tip 2: KNOW YOUR GEAR:
You may feel pressured to have a lot of equipment from your online research or local triathlon group. The most important thing is to be comfortable and able to work with the equipment you have. Run through your gear the night before race day to avoid forgetting anything essential! Here are a few things you do need:
Shoes: Do NOT break in new shoes the day of the race. We often recommend getting running shoes that fit to your gait & tread pattern but go with what you’ve trained in and are most comfortable with. If you have cycling shoes and clipless pedals, be sure to be comfortable with clipping in and out.
Race Kit: You don’t NEED a tri suit for your first race, especially if it is a short course. Swimming in a swimsuit and quickly throwing on shorts and a t-shirt for the other two disciplines will work; I’ve done it and have even thrown on a hoodie for a rather windy bike ride. If you’re lucky enough to have a tri suit for your first race, do a training session or two with it before race day to avoid any surprises. All of these options including your wetsuit (if the race calls for one) can be sleeved or sleeveless. Don’t forget an extra layer if the forecast looks a bit cold.
Wetsuit: To prevent chaffing and to help with removing your wetsuit in the transition zone use petroleum jelly or Vaseline around key connection points like the neck, ankles, and wrists!
Bike: While there is technical assistance on each race, you should feel comfortable with basic maintenance (eg. fixing a flat). Bring a spare tube and CO2 or a small pump in the trusty bike bag. Be comfortable on the bike you are riding, and double check that the gears shift well the night before your race. Give it a test run if you are renting a road bike for your first race. Pump up your tires the morning of to avoid the awful, sluggish ride I endured on my first triathlon. Don’t forget your helmet, sunglasses, and a water bottle!
Your first triathlon is not a race to win: Triathlons are a test of mental endurance. Don’t forget this as you start training for your first triathlon. There are two common issues: struggling with a section too often or exhaustion from trying to keep up with someone else. A 5x Iron man once said: “Understand if the swim if your hardest leg; it is also the shortest a mere 20-40min of the +3hrs often spent on a course.
The bike is your time sitting, eating, drinking and drying off before you set out on a nice scenic run. Some people will beat you in the water but understand they won’t be as comfortable in their splits on land.” For training: BRICK workouts! Try riding your bike the length of the course, and then immediately going for a run. Time yourself and your split times of each kilometer to understand how you feel & where you can improve on your own time. You will encounter a jelly leg feeling and it’s better to encounter this in training than on race day.
TIP 4: START SHORT
While IRONMANs seem exciting to watch and read about, they are extremely taxing on the mind, body, and wallet. Starting with a sprint triathlon allows you to get the jist of a (potentially chaotic) open water swim start, learn how to navigate transition zones, while being able to make some forgiving mistakes. Avoid a race long enough that requires you to worry about fuel (besides a bottle of water on the bike) during your triathlon, as that is a whole other discipline in itself.
TIP 5: LEARN FROM OTHER ATHLETES
Finding a group to train with can boost confidence (and speed). A seasoned athlete can easily tell you what to look out for, and can give simple but important tips on your posture/form to help you be a little more aerodynamic. Plus, it’s always nice to have someone there for you on those bad weather training days to keep you motivated!
