Annotation. Purpose: substantiate the results of theoretical and practical investigations aimed at improving the health of students. Material: the study involved 187 children including 103 boys and 84 girls aged 7-10 years. Results: through a rapid assessment of physical health it was found that pupils of primary school age have an average level of the functional state of the organism, with a minimum resistance to risk factors (chronic non-infective diseases, etc.). For the first time, a

... ue for determining the level of adaptation and reserve capacity of school students proposed by Ukrainian hygienists was used in physical culture and sports practice. Conclusions: the technique reveals strain in adaptation mechanisms that corresponds to donozological condition. An idea is proposed that Nordic walking, through the positive impact on the body of aerobic mode of energy supply, is able to increase the reserve-adaptive capabilities of primary school students by improvement of their health as well as to solve the problems of health formation and health care in the physical education of youth. Introduction 1 Generation that was born and is growing now in difficult technology related situation, increased by anthropogenic problems, shall have much more reserve of health for resisting to stressful challenges of society. Junior school age is the period of socialization's completion, when a child adapts to interaction with external factors and, on this base, starts to form internal beliefs. It is not occasional that physical culture specialists determine this age as "dynamic state, characterized by reserve of functions and systems and is the base of individual's fulfillment of his (her) biological and social functions. Integral indicator of reserves of organs' and systems' functions is energetic potential of bio-system (reserve of energy creation)" [6, Pg. 17]. The problem of formation of positive and, what is the most important, efficient attitude of junior schoolchild to valuelogical values of physical culture acquires special importance; here great attention shall be paid to formation of dominant, even biased belief that it is impossible to have good health without own efforts and personal motion functioning. In family and on first school (pre-school) lessons of physical culture it is necessary to educate children's wish to endure physical loads, cognitively supporting it by knowledge about usefulness of such motion functioning. It is not occasional that foreign specialists call physical inactivity a leading risk factor in global prevalence of diseases [15] . To day not infectious diseases together with hypodynamia are the most serious problem in developed countries of the world, because their after effects undermine the strength of country. Owing to absence of sufficient motion activity of mature people they start suffering from chronic diseases, reducing efficiency of their labor and worsen quality of life. Competitiveness of a person also reduces and adding to this factor mass character of this problem, we receive economic stagnations. Some countries, UN and WHPO understood this fact very well and recent decades they have been investing recommendations and practical measures just in struggle with non infectious diseases. At ninth European conference of Ministers of health protection, devoted to health protection in countriesmembers of EU a declaration was adopted, according to which investments in children's health and welfare ensure improvement of results during all life and can reduce the burden, endured now by health protection and social provisioning authorities. It was conditioned by the fact that a lot of physical and social-psychological problems could have been avoided, because their roots are in baby and infant age. [Information about ninth European conference of Ministers of health protection of EU, devoted to health protection problems//Modern pediatrics.-2011. -№ 5(39). -Pg. 13]. However, no positive results are possible without orientating of children on axio-sphere of physical culture [8]. G.L. Apanasenko considers physical loads to be the best mean for increasing of health's reserve potentials [2]. It means that health level, stress-resistance, ability to endure psychic problems depend on charge and quantity of mitochondrion, deposited in the process of physical trainings. M.M. Bogen, basing on literature data and own practice formulates a hypothesis: "Mitochondrion component of energy generation, ensuring energy supply for life functioning and, consequently, for cells' work in alive organism,is an essential mechanism of development of general endurance and a form of its manifestation -special endurance" [3, . Profound foreign researches [9] found that under condition of purposeful (pedagogic) physical loads (with active muscles' work, resulting in tiredness) mitochondrion in tissue of skeleton muscles are quickly and specifically change; owing to this fact mitochondrion volume can reach up to 50% during several weeks and even more in organisms of not trained earlier persons. Aerobic loads "charge" cells in the best way, creating efficient reserve of health, while practicing of Scandinavian walking is the best way for solution of health related tasks.
