Physical activity zltitude high considegations is often done by endurance athletes to improve their sporting performance. Because of this, we often have to extrapolate from data obtained at higher altitudes when seeking to establish recommendations about training at mid-range altitude. DHM along with the plant it's extracted from, Hovenia Dulcis, is a herb that has been used for hundreds of years in traditional Chinese medicine.

Nutritional considerations for high altitude training -

Athletes competing in this environment should try to spend at least four days in this environment prior to competition.

This allows the body to make appropriate adaptations to resolve acute mountain sickness. The high-altitude environment is lower in oxygen, so assuring good iron status with no sign of iron deficiency or anemia is important.

If performing endurance activity in this environment, spending even more time at high-altitude is important to improve red-cell concentration and oxygen-carrying capacity. Of course, increasing red-cell concentration increases the requirement for selected nutrients, mandating a diet rich in high-iron, high-vitamin B12 foods red meats, etc.

Frequent eating at planned timed intervals, with a focus on high carbohydrate foods is important because carbohydrate requires less oxygen to metabolize for energy than either protein or fat.

Insufficient energy intake reduces both strength and endurance, both critical factors in athletic performance. Frequent eating requires advanced planning to make certain there are planned eating times during the day about every three hours and available foods that can be easily accessed.

Because of the nausea commonly experienced at the beginning of the adaptation process, eating smaller amounts with greater frequency may be a useful strategy to help assure adequate intakes.

Athletes should monitor how much fluid was consumed and add an amount needed to sustain body weight. If the athlete cannot carry fluid with them, there should be known and available hydration stations that the athlete can access with ease and in high frequency.

It is important to focus on the consumption of high carbohydrate foods to help optimize glycogen stores, which are used at a higher rate in cold and high-altitude environments.

Having frequent carbohydrate consumption will also help to sustain blood sugar and, therefore, mental function the brain is a high consumer of blood sugar. It will also provide a source of fuel to working muscles that does not require oxygen to metabolize.

Plan so that the athlete never gets hungry or thirsty and has enough available energy to compensate for the extra that must be used at high-altitude.

RELATED: Altitude Acclimation: 5 Tips for Optimizing Performance. As with any environmental condition, there is a range of nutritional demands. A mildly warm day will require different nutritional strategies as compared with one of searing heat and humidity ; similarly, with rising altitude there will be greater effects.

For the most part, when endurance athletes talk of moderate altitude, they are talking somewhere in the range of 5, to 8, feet 1,, meters. Extra fluid intake is vital. Rising altitude means that breathing is shallower and more frequent; this increased ventilation along with dry air leads to greater fluid losses through the respiratory system.

Additionally, sweat evaporates quickly, which can lead you to believe you are not losing much fluid and are less inclined to drink. When training or competing at altitude, carry more fluid than you would regularly and keep drinking to avoid dehydration.

Even on shorter runs that you would complete at sea level without water, it is a good idea to use something such as a hydration belt or a handheld quick draw when training at altitude; you are more likely to drink often when fluid is readily available.

RELATED: Are You Doing Thirst Right? The Science Says Probably Not. Basal metabolic rate BMR increases at altitude, especially in the first couple of days. Appetite is also suppressed by hypoxia, so to minimize reduction in body mass and loss of muscle, take care to match your caloric needs.

With time to acclimatize, BMR drops again, but not quite to base level sea level rate. There also seems to be a shift in fuel utilization toward a greater reliance on carbohydrate as opposed to fat stores.

If flying in for a race, you might consider frequent small meals that are carbohydrate-rich to maintain energy levels. Carbohydrate-rich sports drinks would also be beneficial in meeting both increased fluid and carbohydrate needs.

As the body tries to adapt to a lower oxygen concentration in the air, greater numbers of red blood cells, which transport oxygen to working muscles, are produced by the bone marrow. In fact, this is the primary reason why endurance athletes train at altitude; to achieve the increase in oxygen-carrying capacity and the associated improvements in endurance capacity.

What Happens to Your Body When You Adapt to Training at Altitude? There are physiological adaptations that happen at altitude that are beneficial for endurance, high intensity team sports, and anaerobic sports. Benefits of acclimatization include:. Increased oxygen capacity of blood by way of increased production of red blood cells. The demands Nutritional considerations for high altitude training on trainign body during fof altitude training require endurance athletes bigh give extra attention to nutrition. There are no precise rules aktitude Nutritional considerations for high altitude training, as several factors come into play, including climate, workout intensity and needs of the individual. However, there are a number of general guidelines that endurance athletes such as triathletes should follow. High altitude training induces an increased breathing rate, which in turn causes a faster loss of fluids through the respiratory system. It is therefore necessary for a triathlete to drink more at high altitudes than he or she would for the same quantity of training at sea level.

However, iron is required to manufacture hemoglobin the oxygen-binding portion of red blood cells and consequently, any iron deficiency can reduce the benefits of altitude training. Before you go to altitude, consider having a blood test to ensure your iron stores are adequate.

Talk to your doctor about your plans to train or race at altitude and if you should consider taking iron supplements. Otherwise, include iron-rich foods in your diet animal sources such as lean red meats are best absorbed. RELATED: How to Optimize Your Iron Levels — Besides Just Eating Red Meat.

Altitude places stress on the body, which might affect your immune system when combined with hard training. A diet rich in natural antioxidants is perhaps even more important to help the body cope, adapt and stay healthy. Along with a healthy diet, good hygiene habits and plenty of recovery will also help.

Often altitude goes hand in hand with either hot, dry climates or cold conditions. Keep this in mind when it comes to changing nutritional needs.

Remember, too, that individuals adapt to altitude differently. If you can understand some of the changes that happen in your body at altitude, you can understand how nutrition can support how you function.

Before we do so, I want to be clear that the degree to which you experience the changes laid out below depends on the heights you reach and the time you spend at them. Red blood cells contain haemoglobin, a protein that helps transport oxygen to your cells, supporting energy production.

As iron is needed to make haemoglobin, you need to consume more iron at altitude. This will give time to optimise your iron status before entering high altitude, but please note that if you want to adapt to altitude then the most important thing is your iron intake while at altitude, not your iron status before you go.

How much iron should you take? To maximise the effects of altitude on your haemoglobin, taking to mg elemental iron per day usually works well, and m ost studies showing this have had people consume iron salts e.

Digestive discomfort is perhaps the most common side effect people get when supplementing iron, and you might be able to reduce this by splitting your daily dose in two , with half your supplemental iron in the morning and half in the evening. The only downside to this is that consuming all your supplemental iron as one dose might be slightly better at boosting your haemoglobin.

To enhance how well you absorb iron, take it with a rich source of vitamin C , such as a citrus fruit. Note also that certain plant-borne chemicals e.

Finally, as haem iron found in animal foods, such as red meat is much better absorbed than non-haem iron, the above is likely especially relevant to vegans and vegetarians! As a result, many people struggle to meet their energy needs at altitude, making them prone to injuries and the other problems Emily Jevons outlined in this blog.

You might be wondering whether altitude will change how much carbohydrate and fat you burn. Muscle protein breakdown goes up too, so since it can be hard sourcing high-quality protein at altitude, snacks such as Rebuild Long Range Fuel come into their own.

All of this means you probably just need to eat more in general at altitude, which you can make easier by choosing more calorie-dense foods e. How did I get my energy? The combination of low humidity, little oxygen in the air, and increased breathing rate all increase how quickly you lose fluid, and this is compounded by increased urination diuresis on initial exposure to altitude.

Of the different substances that counter the performance-impairing effects of being at altitude, nitrates might be particularly helpful for some of us. Commonly consumed in the form of concentrated beetroot juice, nitrates are a precursor to nitric oxide, a gas that improves blood flow and oxygen delivery to cells.

Through these mechanisms and others, nitrate supplementation can increase the oxygen content of blood in arteries and improve exercise economy , meaning that less oxygen is needed to complete a given endurance task.

It is clear that any competition at altitude will benefit from acclimatization, or adaption to changes in physiological and metabolic demands. Systems that react to altitude and changes in oxygen pressure include cardiovascular, pulmonary and endocrine and the central nervous system, meaning changes in resting and maximal heart rate, rates of ventilation, blood pressure, VO2 max and oxygen transport. Nutritional support of these adaptations and systems during altitude acclimatization is crucial.
