title: [Factors determining the functional state of regulatory systems in athletes after return from altitude conditions].
abstract: We have studied a group of athletes who compete in speedpower disciplines. The athletes spent a period of time at the altitude of 2100 meters and the state of their regulatory systems was measured on their return to normal conditions. We have shown that training at the altitude improves the functional state, shifts the vegetative balance towards the prevalence of vagus influences, and improves stamina. The positive effects remain as long as 25-26 days after return from the altitude. At the same time for sportsmen after training at the level of sea in a state of relative rest and central and sympathetic influences prevail at the functional loading. In addition, the factor of the unstable states also begins to play a certain role forming of reaction of organism on loading.
