Features of the child's body

1. A large value of the ratio of body surface area to body weight
2. A large amount of energy consumption during locomotives
3. Less sweating
4. Lower minute blood volume with an equal amount of metabolic demand
5. A large amount of heat exchange between the body and the environment
6. More heat generated during muscle work (in terms of kg of body weight)

According to the study of the state of the cardiovascular system, there was a clear pattern of changes in oscillography and seismocardiographic indicators depending on age and level of motor fitness. At the same time, there were no pronounced differences in the time and amplitude parameters of the seism cardiogram in different climatic seasons of the year.


Experimental studies on a contingent of young athletes have revealed that high external temperature significantly affects the activity of the cardiovascular system. Thus, in the hot season, there was a tendency to decrease the maximum arterial blood pressure and decrease the oscillography index up to filamentous records, while there was a decrease in the amplitude of systolic and diastolic cycles.
It should be pointed out that during the winter period of the training cycle of their preparation, the maximum arterial blood pressure increased in comparison with the data of the summer period in 40% of cases, it fluctuated within the limits of 145-155 mmHg, which in our opinion is due to non-compliance with the rest regime and irrational construction of the training load.
In order to favorably form, preserve and improve dynamic stereotypes when exercising in conditions of high external temperature, it seems rational to observe the regime of intermittent loads using rest pauses that preserve the hypothermic effect in conditions of overheating and prolonged muscle work.
