Objective: The work objective was to reveal a correlation relationship between the parameters of the cardiovascular system functional state and the trajectories of morpho-functional and Response Quality Indicators in 7 year old children.

Materials and methods: 303 first grade children at the age of 7 were involved in this prospective observational cohort study. PWC170 test has been performed, Body Tension Level (BTL) and Response Quality Indicator (RQI) have been computed as the parameters, closely linked to the Physical Working Capacity. The data have been analysed through ranking comprehensive estimates. Weighed Mean values (М), Standard Deviations (SD), and 95% Confidence Intervals (CI), correlation ratio (r) were computed.

Results: In 76% of first-grade pupils, a low adaptive reserve to exertion is seen. A significant correlation relationship between PWC170 indicators and BTL is shown. In the vast majority of cases, overweight is related to not only large fat folds, but also unsatisfactory RQI values. It indicates that physical education program is inefficient.

Conclusion: Incorporation of a complex indicator of the Physical Working Capacity into screening control of the child population health will enable unbiased evaluation of the efficiency of organising physical education, taking the functional state of the body systems into consideration.
