Abstract
The aim the work. Perception and a motor ability are two main activities, which determine orientation in the surrounding reality and responding to it. The visual-motor coordination is a skill that enables defining a body position and its changes during a movement in space and time, referring to an area of activity or a moving object.The material and methods. The aim of this research was to evaluate postures of girls aged 14-16 measured with Moiré's photogrammetric method, evaluate the visual-motor coordination measured with the cross-matching test and show the connection between a body posture and the visual-motor coordination. The visual-motor coordination was tested by using the computer and a standard keyboard as well as a black and white screen (VGA). 153 girls took part in the research, including 52 14-year-olds, 50 15-year-olds and 51 16-year-olds from the Grammar School number 3 in Starachowice. The research was done in May 2004.The results. The lateral curvantures of the spine were the most common - 80 (52%). There were 72 cases (47%) of posture asymmetries. Concave backs dominated among defects in the sagittal plane-51 (33%). There was one case of rounded back in the group of 16-year-olds. There were 23 cases (15%) of flat backs. The best result in the cross-matching test was obtained by 16-year-old girls (102,30s), and then there were 15-year-olds (105,4s) and 14-year-olds (113,20s).The conclusions. The analysis of correlation coefficients does not make it possible to state clearly that there is an essential dependence between some posture characteristics and the time of a visual-motor coordination simple. The issues connected with body postures and elements of movement coordination need further examination.
