Analysis of high-intensity physical activity biological feasibility within the framework of children health training

Abstract

Epidemiological surveys reflect a negative trend in functional indicators for children’s physical health. In recent surveys it is experimentally proved that unlike other methods of training, high-intensity interval training (HIIT) produces prevailing positive effect onto the indicators of physical and functional condition of children with poor health. However, the review of studies suggests that the stated idea turns to be controversial. There is the evidence of possible negative effects of intense physical activity due to the low level biological reliability of adaptation mechanisms and other anatomical and physiological characteristics of children. Therefore, it is necessary to provide a scientifically based conceptual model of timeline for children’s health training in which the central health impetus will be HIIT.
