CHAPTER 1. INFLUENCE OF REGIONAL FACTORS ON THE PHYSICAL FITNESS OF CHILDREN AND YOUTH STUDENTS
The vital activity of the organism is subject to the influence of climatic factors of the region of residence. However, the magnitude of this influence on the indicators associated with the motor capabilities of a person has not yet been studied fully enough.
1.1. THE PROBLEM OF THERMOREGULATION OF THE HUMAN BODY (basic theory)
Keeping the temperature of the core ("core") of the body at a constant level is an essential guarantee of normal functioning.
organism and even its existence. Humans can usually tolerate body temperature changes of up to 4°. Only for a very limited time can the internal temperature exceed 41°C. In essence, warm-blooded animals, including humans, maintain a temperature balance at a level very close to the maximum possible; only a few degrees of internal body temperature distinguish a person who is in conditions of thermal comfort, who is on the verge of death.
It is not surprising that with such stringent requirements for thermoregulation, as a result of human evolution, the finest mechanisms for maintaining a constant body temperature under various conditions have been formed. But, if when a person is in conditions of low external temperatures, his protection is mainly provided by warm clothes, being indoors and other activities, so to speak, of a social and behavioral nature, then in the case when a person is in conditions of high external temperatures, the main role in the regulation and maintenance of heat balance is played by physiological factors. That is why thermoregulatory mechanisms that provide a constant body temperature are mainly aimed at protecting a person from excessive overheating.
Naturally, this task becomes especially important when it comes to long-term residence of a person in conditions of high external temperatures. But the problem of thermoregulation acquires particular urgency in connection with the motor activity of a person and, especially, physical exercises. Therefore, the issues of thermoregulation during the performance of muscular work in conditions of high external air temperatures are of particular interest. In recent years, an exceptionally large number of studies have been carried out in this direction. Without pretending to be a complete review, we will describe below the main information accumulated to date and practical recommendations.
Let us turn, first of all, to the fundamental issues of thermoregulation of the body
