Effects of high altitude essay

Altitude training for sea-level competition In: Internet Society for Sport Science. Training near sea level while living at an altitude of m ft for a month enhances subsequent endurance performance, probably by increasing the oxygen-carrying capacity of the blood through an increase in production of red blood cells.

Share on Facebook The terrain and scenery at high altitudes can be incredibly beautiful and peaceful. It can also be tough on your body if you're not acclimated to it. The low levels of oxygen that high altitudes subject you to can make you feel tired, weak and can lead to severe altitude sickness in extreme cases.

If you're venturing to the mountains for some exercise, it's important to understand the risks of altitude sickness and the things you can do to make your acclimatization as comfortable as possible.

Physiological Response to High Altitudes There are several things that happen to your body when exercising at high elevations. Blood oxygen, blood plasma, blood volume and stroke volume are all reduced, while fluid loss, heart rate and metabolic rate increase.

Your breathing rate increases as your body attempts to get adequate oxygen. Increased respiration then raises the acidity of your blood. Because your oxygen intake is decreased, your VO2 max -- the maximum amount of oxygen your body is capable of utilizing -- is decreased.

All of these things combine to create a sensation of sluggishness and fatigue at high altitudes that you wouldn't experience at sea level.

Dangers of Altitude Sickness Whenever possible, you should slowly increase altitude to avoid acute mountain sickness, or altitude sickness.

Basic symptoms are common and include headache, nausea, dizziness, loss of appetite, shortness of breath and difficulty sleeping. Symptoms are often worse at night, but will usually begin to subside within 48 hours.

Moderate altitude sickness symptoms include severe headache, vomiting and lack of coordination.

Curing the symptoms of moderate altitude sickness requires descending to lower altitudes or medication. In severe cases, persistent coughing, bubbling sounds in the chest, convulsions and double vision can occur.

Medical attention must be sought immediately if any severe symptoms become present.

At elevations over 3, feet, your VO2 max will decrease about 2. Because your VO2 max is reduced, you won't be able to exercise with the same intensity that you can maintain at sea level.

Instead of performing long, endurance exercises, practice short, intense training sessions until your body adapts. Other Tips Nutrition and hydration are two other important considerations to make during high-altitude exercise.

Your resting metabolic rate increases and your body experiences an elevated demand for carbohydrates at high elevations, so calorie consumption should be increased.

Altitude Sickness

Up your fluid consumption before and during exercise to combat rapid dehydration, which can be caused by the dry air and increased respiration. Be sure to wear sunscreen when exercising outside, since UV exposure is increased at higher altitudes. Your body produces more free radicals when you exercise at higher elevations, so taking a daily antioxidant is also a good idea.Altitudes above 8, feet can cause major physiologic effects, including decreased oxygen delivery to tissues, increased pulmonary vasoconstriction, and increased sympathetic nervous outflow.

Responses to high altitudes differ among cardiovascular (CV) patients, but most will see an earlier onset of symptoms at higher elevations.

Effects of High Altitude Essay Hypoxia is the main physiological complication when ascending to high altitudes. The percentage of oxygen in the atmosphere stays the same, but the partial pressure and barometric pressure begin to drop on rising to a higher altitude.

A good compilation of high altitude cooking information that is not easy to find in one place. I recently was making caramels and at ft with my Thermapen and ruined a couple of batches until I realized that candy temperatures needed to be adjusted.

Second, people born and raised at high altitude appear to have a lower prevalence of tuberculosis than those living at sea level, but whether this is strictly a protective effect of low ambient oxygen tension related to a decreased rate of mycobacterial growth, transmission, and development of disease—or other factors—is debatable.

The effects of training and, more recently, sleeping at high altitude on athletic performance have been studied in the West for more than 30 years. During that time, these practices have become an almost essential aspect of the preparation of world-class competitors. Prolonged stay at high altitude significantly lowers the incidence of some of the diseases commonly encountered at sea level. This conclusion is based on a study involving , men stationed on plains between m and sea level and 20, men stationed at altitudes between and m during.
