[Physiological hygienic characteristics of the teaching by the new educational programs for grade III].

The effect of the new training curricula and plans on the reactivity, health state and physical development of third-grade pupils is studied. Simultaneously with researches into the experimental class, investigations are conducted in a control class also. The working-capacity curve in the experimental-class pupils yields more clearcut fluctuations in a negative sense, interpreted as an expression of greater fatigue, as compared to the control class. This is confirmed by reliable data about the changes in the functional state of the higher nervous activity, hemodynamics and neuroendocrine regulation. It is concluded that the hygiene-physiological characteristics of the reactivity and health state of pupils, trained according to the new curricula, gives sufficient reason to stress the necessity of accurate assessment and rather prolonged medico-pedagogic observation with a view to obviate the cumulation of the described above negative effects on the organism of teenagers.
