We are in pre-season physical preparation time for most sports teams. The demands of each session can be explained, is that the calendar is very long and fitness is crucial in achieving results. You’ve probably seen many teams go to distant countries at high altitudes, especially cyclists. Choosing these places is not random , it is done by a simple physiological reason. This form of training emerged from the Mexico Olympics in 1968, by which time it had to restate the fact train a departure from the usual altitude. We train to talk a bit more about the famous high altitude training.
At higher altitudes, less atmospheric pressure, that fact must start. When we change the height also varies the concentration of oxygen in our lungs and have a smaller amount for our body . Consequently our body triggers a series of reactions due to the automatic nature of survival we have, among which include:
Increased heart rate to meet the needs of oxygen to all tissues, even if they are under more physical effort.
Increased number of breaths per minute to capture more oxygen.
And most importantly, the increase in the hormone responsible for producing red blood cells: erythropoietin (EPO)
If the number of red blood cells also rises the amount of oxygen carried in the blood, and thus the performance is higher when returns to normal heights at which time these adaptations are stored in the body. This is the main reason the height training or also known as hypoxic conditions .
However it is not enough to go to a high altitude and train as in the place of origin. Experts set a height should be between 2000 and 2600 meters , discouraging exceed 3000 meters. You can also have consequences in technical and tactical players to train under strange conditions, but the benefits will be higher as long as it is strategically planned. According Bell in 1996, the process of increasing the EPO is produced from the 5 to 7 days . Another option used by elite athletes is the “live high, train low” using a hypoxia machines that simulate altitude conditions while sleeping.
Note that these situations change in a different physiology of each individual and, although there are general rules so you have to measure carefully what you do with these workouts. There are differences between doping and ergogenic , with altitude training a middle ground that can be legal if used correctly or transfusions punishable if not permitted by regulations occur.
