Altitude Tent
An altitude tent is a sealed tent used to simulate a higher altitude with reduced oxygen. Living or training at altitude causes the body to adapt to the lower oxygen content by producing more oxygen-carrying red blood cells and hemoglobin, thus causing the body to adapt to the higher altitude and enhancing performance when returning to a lower altitude. Mountain climbers can use them to avoid altitude sickness, and athletes can use them to enhance performance at lower altitudes. History Altitude tents were first marketed in the mid-1990s, and are provided by many different companies in a number of designs. Rationale Sleeping in a simulated altitude environment allows the body to achieve some of the positive adaptations to altitude while still permitting the athlete to perform workouts at an oxygen-rich lower altitude where muscles can perform at their normal work level. An altitude tent is one way to enable athletes living at any elevation to sleep in a high altitude-like envir ...

Tent
A tent () is a shelter consisting of sheets of fabric or other material draped over, attached to a frame of poles or a supporting rope. While smaller tents may be free-standing or attached to the ground, large tents are usually anchored using guy ropes tied to stakes or tent pegs. First used as portable homes by nomads, tents are now more often used for recreational camping and as temporary shelters. Tents range in size from " bivouac" structures, just big enough for one person to sleep in, up to huge circus tents capable of seating thousands of people. Tents for recreational camping fall into two categories. Tents intended to be carried by backpackers are the smallest and lightest type. Small tents may be sufficiently light that they can be carried for long distances on a touring bicycle, a boat, or when backpacking. The second type are larger, heavier tents which are usually carried in a car or other vehicle. Depending on tent size and the experience of the person or people in ...

Camping
Camping is an outdoor activity involving overnight stays away from home, either without shelter or using basic shelter such as a tent, or a recreational vehicle. Typically, participants leave developed areas to spend time outdoors in more natural ones in pursuit of activities providing them enjoyment or an educational experience. The night (or more) spent outdoors distinguishes camping from day-tripping, picnicking, and other similarly short-term recreational activities. Camping as a recreational activity became popular among elites in the early 20th century. With time, it grew in popularity among other socioeconomic classes. Modern campers frequent publicly owned natural resources such as national and state parks, wilderness areas, and commercial campgrounds. In a few countries, such as Sweden and Scotland, public camping is legal on privately held land as well. Camping is a key part of many youth organizations around the world, such as Scouting, which use it to teach bot ...

Oxygen Tent
An oxygen tent consists of a canopy placed over the head and shoulders, or over the entire body of a patient to provide oxygen at a higher level than normal. Some devices cover only a part of the face. Oxygen tents are sometimes confused with altitude tents as used by athletes and those looking to acclimatize to a higher altitude, but those contain a reduced oxygen content. This form of treatment is often prescribed in conditions where people have difficulty in breathing. An oxygen tent can be used in either a hospital setting or outside a health-care facility, and can be recommended for short- or long-term therapy. Typically the tent is made of transparent plastic material. It can envelop the patient's bed with the end sections held in place by a mattress to ensure that the tent is airtight. The enclosure often has a side opening with a zipper. Benefits Oxygen therapy often benefits patients by providing more oxygen to their lungs and consequently to their tissues. Typically ...

Hyperbaric Oxygen Therapy
Hyperbaric medicine is medical treatment in which an ambient pressure greater than sea level atmospheric pressure is a necessary component. The treatment comprises hyperbaric oxygen therapy (HBOT), the medical use of oxygen at an ambient pressure higher than atmospheric pressure, and therapeutic recompression for decompression illness, intended to reduce the injurious effects of systemic gas bubbles by physically reducing their size and providing improved conditions for elimination of bubbles and excess dissolved gas. The equipment required for hyperbaric oxygen treatment consists of a pressure chamber, which may be of rigid or flexible construction, and a means of delivering 100% oxygen. Operation is performed to a predetermined schedule by trained personnel who monitor the patient and may adjust the schedule as required. HBOT found early use in the treatment of decompression sickness, and has also shown great effectiveness in treating conditions such as gas gangrene and carbon mo ...

Hypoxicator
A hypoxicator is a medical device intended to provide a stimulus for the adaptation of an individual's cardiovascular system by means of breathing reduced oxygen hypoxic air and triggering mechanisms of compensation. The aim of intermittent hypoxic training or hypoxic therapy conducted with such a device is to obtain benefits in physical performance and wellbeing through improved oxygen metabolism. There are several commercial systems available. Most of these systems have not been cleared for medical applications by the FDA and are used by athletes for altitude training. Advanced hypoxicators have a built-in pulse oximeter used to monitor and in some cases control the temporary reduction of arterial oxygen saturation that results in physiological responses evident at both systemic and cellular levels even after only a few minutes of hypoxia. Hypoxic Training Index (HTi) can be used to measure the delivered therapeutic dosage over the training session. The underlying mechanism ...

Altitude Training
Altitude training is the practice by some endurance athletes of training for several weeks at high altitude, preferably over above sea level, though more commonly at intermediate altitudes due to the shortage of suitable high-altitude locations. At intermediate altitudes, the air still contains approximately 20.9% oxygen, but the barometric pressure and thus the partial pressure of oxygen is reduced. Depending on the protocols used, the body may acclimate to the relative lack of oxygen in one or more ways such as increasing the mass of red blood cells and hemoglobin, or altering muscle metabolism. Proponents claim that when such athletes travel to competitions at lower altitudes they will still have a higher concentration of red blood cells for 10–14 days, and this gives them a competitive advantage. Some athletes live permanently at high altitude, only returning to sea level to compete, but their training may suffer due to less available oxygen for workouts. Altitude training ...

Gamow Bag
A portable hyperbaric bag, of which one brand is the Gamow () bag, is an inflatable pressure bag large enough to accommodate a person. The patient can be placed inside the bag, which is then sealed and inflated with a foot pump. Within minutes, the effective altitude can be decreased by 1000 m to as much as 3000 m (3281 to 9743 feet) depending on the elevation. The bag is pressurised to ; the pressure gradient is regulated by pop-off valves set to the target pressure. History The Gamow bag was named after its inventor, Igor Gamow, son of George Gamow. Igor Gamow originally designed a predecessor to the Gamow bag called "The Bubble" to study the effect of high altitude on stamina and performance in athletes. Gamow later re-designed "The Bubble" into a bag that could be used in high-altitude wilderness. Application It is primarily used for treating severe cases of altitude sickness, Gov't Doc # USARIEM-TN94-2. high-altitude cerebral edema, and high-altitude pulmonary ed ...

Erythropoietin
Erythropoietin (; EPO), also known as erythropoetin, haematopoietin, or haemopoietin, is a glycoprotein cytokine secreted mainly by the kidneys in response to cellular hypoxia; it stimulates red blood cell production (erythropoiesis) in the bone marrow. Low levels of EPO (around 10 mU/mL) are constantly secreted in sufficient quantities to compensate for normal red blood cell turnover. Common causes of cellular hypoxia resulting in elevated levels of EPO (up to 10 000 mU/mL) include any anemia, and hypoxemia due to chronic lung disease. Erythropoietin is produced by interstitial fibroblasts in the kidney in close association with the peritubular capillary and proximal convoluted tubule. It is also produced in perisinusoidal cells in the liver. Liver production predominates in the fetal and perinatal period; renal production predominates in adulthood. It is homologous with thrombopoietin. Exogenous erythropoietin, recombinant human erythropoietin (rhEPO), ...

Blood Doping
Blood doping is a form of doping in which the number of red blood cells in the bloodstream is boosted in order to enhance athletic performance. Because such blood cells carry oxygen from the lungs to the muscles, a higher concentration in the blood can improve an athlete's aerobic capacity (VO2 max) and endurance. Blood doping can be achieved by making the body produce more red blood cells itself using drugs, giving blood transfusions either from another person or back to the same individual, or by using blood substitutes. Many methods of blood doping are illegal, particularly in professional sports where it is considered to give an artificial advantage to the competitor. Anti-doping agencies use tests to try to identify individuals who have been blood doping using a number of methods, typically by analysing blood samples from the competitors. History Blood doping is defined as the use of illicit products (e.g. erythropoietin (EPO), darbepoetin-alfa, hypoxia-inducible factor (H ...
