Od naših plavalcev poleg Tjaše Vozel, še kakšen plavalec to uporablja? Ali samo ona?

Mislim, da je višinski šotor uporabljal tudi daljinski plavalec Rok Kerin.

Še moje mnenje.

Tjaša tega šotora ne bi uporabljala, če bi bilo to po pravilih mednarodne zveze definirano kot doping. Poleg tega tudi ne bi kar spustila novinarjev v sobo in povedala kaj počne, se vam ne zdi? Wink

Če gredo športniki na višinske priprave, je ok, če pa uporabljajo šotor, ki jim nudi podobne pogoje v domačem kraju pa ni ok? Smile

Ne vem, če je zdravo, ampak ocitno sta Igor in Tjasa preucila prednosti in slabosti in ugotovila,da je vec prednosti.
Je mogoce za telo dobro, da se toliko trenira? Saj tudi to pusca posledice. V vrhunskem sportu je pac tako, da moras veliko zrtvovat.

Tudi višinskih priprav si ne morejo vsi privoščit. Ali pač? Smile

Vem, da ste vsi zelo proti dopingu, tudi sama ga ne podpiram, ampak počasi bi lahko ugotovili, da tale šotor ni najhujši problem športa.

Svoje mnenje sem podala, ker se mi zdi nesramno kako ste se spravili na Tjašo in se mi ni zdelo fer. Jo je kdo sploh vprašal/prosil za mnenje? Smile

Čist vsi športniki na svetu lahko gredo na višinske priprave v hribe. Simuliranje višinskih priprav je pa drugo. To ni enako Snežak. In tega si ne more privoščit vsak.

Se ti zdi nesramno, da smo se spravili na Tjašo. Kdo se je spravil na Tjašo? Mi govorimo o športnikih, ki uporabljajo te naprave. Med njimi je tudi Tjaša Vozel tako, da je čist normalno, da se večkrat zasledi v tem primeru njeno ime.

V Italiji je uporaba višinskega šotora prepovedana. Za njih je to doping.

V moji buči se pol jaz vprašam, da če morda imajo Italijani v tem primeru prav.

Zdaj pa ti meni prosim razloži, kje ti vidiš tukaj nesramnost?

Drugače pa je čist jasno kako to deluje.

Altitude tent

An altitude tent is something that stimulates the body to an existing altitude. Red blood cells carry oxygen to the body; athletes benefit from increased delivery of oxygen to the muscles, and mountain climbers can avoid altitude sickness by better utilizing the diminished amount of oxygen found at higher altitudes.
The basic concept of living or training at altitude is to cause the body to adapt to the lower oxygen content by producing more oxygen-carrying red blood cells and hemoglobin. This improves the athlete’s ability to perform work, because more oxygen is available to the working muscles.
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 sleep in a high altitude-like environment. A more expensive option gaining popularity amongst professional athletes is to convert their entire bedroom to altitude.
Rather than simulating altitude with actual low air pressure (which would require substantial engineering and the use of an airlock to prevent implosion), the altitude tent remains at normal air pressure, substituting low concentration of oxygen for low pressure. While normal air contains 20.9% oxygen independent of altitude, the air in an altitude tent contains as little as 12% oxygen (the remainder being nitrogen). The partial pressure of oxygen inside the tent is the same as it is at the natural elevation that the tent is simulating.
Most altitude tents create the low-oxygen environment with a “hypoxic air generator” outside the tent pumping the hypoxic (low oxygen) air into the tent. This displaces the more oxygen-rich air inside the tent and with it the excess carbon dioxide exhaled by the occupant(s). Most athletes use altitudes between 8,000 and 15,000 feet. To cause a physiological response, the altitude must be sufficient to reduce blood oxygen saturation (sometimes measured by a pulse oximeter) to approximately 90%.
The tents themselves come in several styles. Unlike camping tents, altitude tents cannot have much ventilation, and often substitute clear plastic windows for the typical nylon and mesh vents. Displaced air escapes the tent through small outlets, seams, or zippers. Air delivery can be through hose long enough to allow the generator to be placed in a different room, reducing noise. Tents are typically placed on the bed, with the floor of the tent between mattress and box springs.
One challenge with altitude tents is the build up of heat and humidity. Because of the use of plastic panels to reduce exchange with the room, heat and humidity can build up in an altitude tent. Some tents allow the use of air conditioners to maintain comfortable conditions. Carbon dioxide from exhaled air can also build up to uncomfortable levels if air exchange is too low. In recent years, advances in altitude tent design, and in the performance of the hypoxic air-supply units, have all resulted in greater air-exchange and significantly lower noise levels.
An alternative to the sealed altitude tent is the altitude canopy, which drapes over the user's bed, and features a weighted edge instead of a tent floor. The canopy maintains high altitude even though there may be small gaps around the edge by maintaining a high flow rate of hypoxic air through the canopy, effectively preventing room air from entering the gaps. By virtue of smaller internal volumes, canopies come to altitude faster than conventional altitude tents.

The ethics of the use of these devices by athletes has been discussed by the World Anti-Doping Agency (WADA), which claimed that it could be equivalent to blood doping and therefore they should be banned; however, on September 16, 2006, Dick Pound of the WADA announced that "...the overwhelming consensus of our health, medicine and research committees – was that, at this time, it is not appropriate to do so," [1] No explanation was given as to how WADA would have enforced a ban.
The USADA report on doping in the Lance Armstrong case also indicates that sleeping in an altitude tent can be used to hide doping using EPO, as natural Erythropoietin production is increased, confusing the tests.

Kaj zdaj, hipoksični šotor je doping ali ni? Kako ste se odločili? ssn
