However these races should not be trivialized, because depending on the altitude, the dangers due to the changes of atmospheric conditions can become suddenly very important.<\/p>\n<p>These climbs require good stamina, altitude tolerance and training in basic safety techniques and progression to glacial terrain. This experience is acquired by the practice of high mountain races, and we advise you by participating in a preparation day.<\/p>\n<p><strong>Mont Blanc is not recommended for young people under 18 years old.<\/strong><\/p>\n<h2>Loan, equipment rental, buying tips<\/h2>\n<p>During the preparation of your race, I can lend you some materials.

This acute exposure to hypoxia causes the body to increase its cardiac and ventilatory output.<br \/>\nThese reactions are beneficial since they allow an increase in the amount of oxygen supplied every minute to the cells.<\/p>\n<p><strong>Acclimatization and acclimatization<\/strong><br \/>\nIf exposure to altitude continues beyond a few hours, the body initiates more economical coping mechanisms that will gradually take over from hyperventilation and tachycardia.<br \/>\nThese mechanisms will only be effective if the exposure is progressive and sufficiently prolonged. All these mechanisms constitute the phenomenon of acclimatization which, once well established, leads to a state of acclimatization.<br \/>\nThis state allows a native seaside subject to have physical activity at altitude. The speed and quality of adaptation vary by subject.<\/p>\n<p><strong>Physical performance at altitude<\/strong><br \/>\nLiving at altitude does not pose too much of a problem, but as soon as the body increases its energy expenditure as during an ascent, the lack of oxygen becomes a factor limiting performance.<br \/>\nAt the top of Mont Blanc a subject only has 70% of his sea level capacity.<\/p>\n<p><strong>The importance of hydrating in the mountains<\/strong><br \/>\nIn order not to transform the backpack into a tanker truck, without fear of the terrible &#8220;heat stroke&#8221; so much feared by soldiers in forced march, the old experienced guide has a well-honed strategy:<\/p>\n<ul>\n<li>give up any idea of \u200b\u200bperformance, the mountain is not a stadium! ;<\/li>\n<li>adjust the pace of progression and clothing to avoid excessive sweating;<\/li>\n<li>take the time to take a break to remove the gourd from the bag, a privileged moment of conviviality.<\/li>\n<li>&#8220;Drink before thirst&#8221;, these are the commercials of the two major manufacturers of hydration pockets systems &#8230; If the message is sometimes disturbing, it is nevertheless clear: drink or weaken, you must choose.<\/li>\n<\/ul>\n<p>Any practicing endurance or resistance sport must hydrate as soon as the duration of this effort exceeds thirty minutes, except to suffer from a decrease in physical performance. The practice of mountaineering or climbing is no exception to this rule because climatic conditions, generally hot (it is rarely &#8211; 2 \u00b0 C in Algeria, except at night, or in Libya), reinforce or increase water losses.<\/p>\n<p>The body is essentially (for 2\/3) water and the energy plant does not support the lack of water. However, our body loses about 2.5 liters of water at rest and sometimes much more effort, exposing itself to dehydration (or lack of water).<\/p>\n<p>Any loss of 2% of the body weight, less than 1.5 kg for an individual of 70 kg, results in a decrease in physical performance of 20%! It is understandable that the climber who hydrates by compensating for his losses, gains considerably in relation to the one who neglects this state of affairs.<\/p>\n<p><strong>How does one lose water?<\/strong><br \/>\nDehydration: The drop in hygrometric pressure associated with hyperventilation increases water losses through the respiratory tract and promotes dehydration.<br \/>\nby breathing: the exhaled air with each respiratory movement is saturated with moisture; by perspiration: through the pores of the skin, even at rest; by sweating: under stress or in a hot environment, the armpits, the forehead, the back sweat profusely according to the intensity of the effort, the ambient temperature and individual variations.<\/p>\n<p><strong>What to replace lost water?<\/strong><br \/>\nBy pure water more or less added sugar in small quantity (50 g per liter) so as to constitute an isotonic liquid (of the same concentration as the liquids inside the body). Why sugar? Because it is the basic fuel of the cell. And, in such a situation, glucose, fructose or maltose are particularly suitable.<\/p>\n<p>The optimum concentration of diluted sugar is 50 g per liter of water because it is close to that of the plasma (internal environment in which the cell is immersed): it is isotonicity.<\/p>\n<p><strong>What are the signs of dehydration?<\/strong><\/p>\n<ul>\n<li>weightloss ;<\/li>\n<li>thirst for &#8220;late onset, delayed in time&#8221;;<\/li>\n<li>intense tiredness;<\/li>\n<li>dryness of the mucous membranes;<\/li>\n<li>loss of elasticity of the skin. If it gets worse:<\/li>\n<li>consciousness disorder &#8220;lethargy type&#8221;;<\/li>\n<li>fast and shallow breathing;<\/li>\n<li>pulse small and fast;<\/li>\n<li>arterial hypotension (less than 10);<\/li>\n<li>hyperthermia<\/li>\n<\/ul>\n<p><strong>Which gourd system to use?<\/strong><br \/>\nStandard or insulated gourd or Camel bak?<br \/>\nBeware the typical Camel back systems have the disadvantage of freezing at altitude or very cold.<br \/>\nPreferably take an insulated flask above 3500 M.<br \/>\nFor those who prefer to use a backpack with built-in hydration pocket of sufficient volume (2 to 3 liters) and with a mouthpiece. The two best-performing manufacturers in terms of price-performance ratio are Hydrapak\u00ae and Camel bak\u00ae, the first manufacturer to appear on the market. Both offer complete, technical ranges, including bags with complete devices.<br \/>\nIn practice, only permanent hydration is the only way to compensate for losses and have enough reserves!<br \/>\n1 to 2 liters of drink being the minimum for a race in the mountains. (keep the champagne for the arrival)<br \/>\nA good evaluation of an optimal hydration is the proof of the existence of diuresis (every two &#8211; three hours, one wants to piss!), Proof of the conservation of an optimal blood circulation of the kidneys, therefore key organs of dehydration. Unfortunately not practical for you ladies.<\/p>\n<p><strong>Acute mountain sickness (MAM)<\/strong><br \/>\nAcute mountain sickness is neither a curse nor a blemish. This is a sign of incomplete acclimation to altitude.<br \/>\nOne out of two subjects has MAM beyond a certain altitude.<br \/>\nThe disorders occur 4 to 8 hours after arrival at altitude and most frequently from 3500m.<br \/>\nThe clinical signs are characterized by a set of disorders associating:<\/p>\n<ul>\n<li>Headache 96% of cases<\/li>\n<li>Insomnia 70% of cases<\/li>\n<li>Anorexia 38% of cases<\/li>\n<li>Nausea 35% of cases<\/li>\n<\/ul>\n<p>Often dyspnea, dry cough, and sometimes dizziness are associated.<br \/>\nEven the best mountaineers can feel the MAM. If you feel any of these disorders your acclimation is incomplete.<\/p>\n<h2>3 RULES OF GOLD<\/h2>\n<ul>\n<li>Do not climb too fast too high.<\/li>\n<li>Climb high enough to acclimatize.<\/li>\n<li>Do not stay too high for too long.<\/li>\n<\/ul>\n<p><strong>Your guide will advise you on the best technique for acclimating to altitude as well as the appropriate treatments to help you adapt.<\/strong><\/p>\n<\/div><\/section><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v16.9 -
