Description
Summary:The work brings forward the results of our pedagogical research, the aim of which was to obtain and widen the knowledge on developmental changes of functional disorders of motor system of 11 to 15-year-old boys and possibilities of their remedy using compensation exercises during physical education and sport lessons. The objects of our observation were 32 boys of an elementary school in Nitra, who were subject to our observation in the consecutive 6th, 7th, 8th and 9th forms. Totally 5 measurements of muscular imbalance and gait were realized. Between measurements No. 2 and 3 an experimental factor was implemented during the period of 4 months. The experimental programme focused on three most frequently shortened muscles and the following muscle groups: knee flexors, musculus rectus femoris and m. quadratus lumborum. By an early and adequate impact of aimed exercises within the P.E. lessons it is possible to affect the incidence of shortened muscles in 11-15-year-old pupils.Original Abstract: Rad donosi rezultate naseg pedagoskog Istrazivanja, cilj kojega je bio dobiti i prosiriti znanje o razvojnim promjenama funkcionalnih poremecaja motorickog sustava kod djecaka uzrasta 11-15 godina mogucnostima njihove korekcije pomocu kompenzacijskih vjezbi tijekom nastave tjelesnog obrazovanje i sporta. Predmeti promatranja su 32 djecaka iz jedne osnovne skole u Nitri, koji su bili predmet promatranja u uzastopnih 6., 7., 8. i 9. razredima. Ukupno je provedeno 5 mjerenja misicne neravnoteze i hoda. Izmedu mjerenja broj 2 i 3 eksperimentalni faktor je proveden u razdoblju od 4 mjeseca. Eksperimentalni program usmjeren je na tri najcesce skracena misica i slijedece skupine: fleksori koljenas, musculus rectus femoris i musculus quadratus lumborum. Skraceni misici su ispitani pomocu metode po Jandi (1982), koja je bila modificirana radi prakse tjelesnog odgoja po Thurzovoj (1992). Kod prvog mjerenja visoke ucestalosti skracenih misica pronadene su kod svih ispitivanih ucenika. Godinu dana nakon toga, porast incidencije od 8 d 11 promatranih misica je zabiljezen. Nakon zavrsetka programa vjezbanja, kod djecaka je zabiljezena manja ucestalost pojavnosti nepravilnosti svih posturalnih misica po 6-41%. Rezultati eksperimenta pokazali su pozitivan ucinak primjene usmjerenih vjezbi unutar obvezne nastave tjelesnog odgoja, sto se znacajno odrazava na status posturalnih misica. Kad smo izostavili naknadu vjezbe nakon prestanka pokusa, znacajan porast incidencije skracenja muskul
