AB  - Study of adaptive response of the 9 years old boys’ respiratory system to controlled isometric exercise in the course of the school year. The dynamics of the lung ventilatory capacity indices as defined at rest as well as the degree of their change due to isometric exercise had been analyzed during the school year in 38 sophomore boys. An automated cardiopulmonary facility AD-03M based on Pentium I processor was used for analysis of the respiratory system indices. Dosed isometric load was created by compression of a hand dynamometer (50% of maximum possible effort within 1 min). Statistical processing of the study results was performed using Student’s t-test. A comparative analysis of the external respiration system of the 9 years old boys during the school year showed positive age-related dynamics of the lung volumes indices and the lung ventilatory capacity at rest. Dosed isometric load results in unfavorable changes in the external respiration indices and reduction of the respiratory system reserve capacity. By the end of the second school year the 9 years old boys experience increase of reactivity and lowering of the respiratory system responses efficiency as a reaction to static exercise.
