Longitudinal study of the influence of corrective gymnastics on improving postural and motor status of children is a brief description of the topic of this research. The research sample consists of schoolgirls aged 11 years (plus or minus six months) at the initial measurement. Two groups of variables comprise: variables for determining of the spine deformities in the sagittal plane (kyphotic and lordotic bad body posture) and variables for determining the motor status of the researched subjects (nine motor tests for the assessment of theflexibility, explosive and repetitive strength of the body). Program of the corrective gymnastics was used as the extracurricular activities of schoolgirls; it lasted three school semesters, with two to three teaching hours per week. Initial, control andfinal tests gave results that were expressed through the canonical discriminative analysis and have showed that the applied program of corrective gymnastics contributed to the total rehabilitation of the kyphotic and lordotic bad body posture, and to the improvement of some dimensions of the motor status.
