摘要：This work is a result of our pedagogical research aimed at obtaining and enlarging the knowledge onevolution changes in the body posture of boys aged 11 - 15 and possibilities of influencing them by means ofcompensatory exercises within the framework of physical education (P.E.). and sport lessons. Object of thestudy were 17 boys attending elementary school in Nitra, who were observed in consecutive years (grades 6through 9). Totally 5 measurements of body posture were executed. Between the measurements 2 and 3experimental factor was implemented during a 4-month-long period. The method by Klein and Thomasmodified by Mayer (1978) was used for the assessment and classification of body posture. High incidence ofwrong body posture was found in all 11 – 15-year-old boys regarding their age. Results of the experimentshowed positive effect of application of aimed exercises within P.E. and sport lessons, focusing on influencingwrong body posture, which was significantly manifested by correct body posture. After finishing theexperiment without any adequate compensatory procedures the motor system of observed boys reacted bythe onset of reversible changes, thus increasing the incidence of indicators of the body posture. There was ashift from 2nd and 3rd qualitative grade into the 4th one in boys (p < 0.05).Based on the results we canstate that by early and suitable impacting of wrong body posture of children aged 11 – 15 years we canreach improvement.
