Physiological and hygienic characteristics of children's motor regime

In primary school age, it is important to take into account the age characteristics of children. The process of ossification of various parts of the skeleton is still far from complete. Due to their high elasticity, they are not capable of significant stress and are malleable to stretching. A group of authors express the opinion that the functional capabilities of the vegetative systems of the body of children are characterized by the following signs, a larger lung surface than in adults, a large amount of blood flowing per unit of time through the lungs and the amount of minute volume of respiration, a large minute volume of blood as at rest and during muscular activity, with high vascular elasticity.
