The level of physical activity of school-aged youth as a determinant of their health. Purpose. Developing of the criteria for the physical activity of optimal level among school-aged youth. Methods. Analytical, epidemiological, sociological, physiological, clinical, mathematical, statistical. Physical activity (PA) was evaluated by the following criteria: type, multiplicity, duration, intensity using an adapted version of questionnaire "QAPACE, Quantification de L'Active Physique en Altitude Chez le Enfants". Children's health was assessed using direct, morbid and subjective indicators. Linear and polynomial regression models, as well as other types of statistical and mathematical analysis, were used to substantiate recommendations for the optimal PA level. Results. It was established that Optimal daily duration of general PA for wellness among school-aged youth is from 4.5 to 5.5 hours. Duration of optimal moderate and high intensity PA (more than 3 MET) is for boys 50-60 min / day or 1.5 hours 4 times / week, for girls - 40-50 min / day or 1.5 hours 3 times / week. Intensive physical activity in this case (more than 7 MET) should occupy not more than 80 % of this time. For the achievement a high level of health, the optimal multiplicity of sports is 3-4 times a week. Moderate and high intensity PA level equaled 40,6 % for urban children and inadequate level of general RA among children in this age group (equaled 64,5 %). Deficient RA has been found to decrease all health indicators of children: morbid, direct and subjective. Two methods of predicting the health risk evaluation for children were created, with using of the complex of determinants, including the level of RA per week. High individual risk of decrease health to level 52 % equaled among urban children in aged 12 to 15 years, according toour studies. The level RA in this group school-aged youth decreases in case of absence of motivation for sports or parents non-active PA, increase of the Product Description popup.authors Yelizarova Olena T.
