[Hygienic and physiological evaluation of the instruction during a 5-day school week].

A longitudinal study of development, reactivity and health state of the students from the initial course, trained during five- and six-day school week was carried out under conditions of full-day organization of the training-educational work. Deviations in the hygienic norms of some moments of daily regime, some results from the dynamics of working capacity and high neurotic morbidity with both forms of organization of trainingeducational work, necessitate essential corrections for its rationalization. Apart from all that, the parallel between the results from the examination of the students, trained during five- and six-day school week in the course of three school years, definitely indicate the following: better working capacity towards the end of school day and week, circulation, realized on a more rational base, better strength indices, lower moment somatic affection and acute morbidity, low number of often-sick-students and more completely healthy students, twice lower neurotic morbidity in favour of the students with a five-day school regime. The results obtained from the complex study, determine the effect of five-day school week on working capacity, development and health of the students to be more favourable from health-hygienic positions.
