Abstract
Introduction. The aim of the research was to determine, which of the analyzed ways of carrying shows the strongest and the weakest correlations with the values after a 10-minute loading with a four-kilogram schoolbag after two-minute restitution. Material, method. The body posture research was carried among a group of 65 children aged 7 with the projection moiré in 4 positions: 1- habitual position, 2- position after a 10-minute loading, 3 – after one minute of the load removal and 4- after two minutes of the load removal. Results. There were analyzed correlations of the differences values of the frontal, sagittal and transversal plane features in a habitual position with the values after a ten-minute loading with a four-kilogram schoolbag as well as with values after two-minute restitution. Conclusions. (1) Carrying a four-kilogram loading in two equal containers on the chest and back or one on the back disturbs body posture statics the least of a 7-year-old student. (2) The fullest restitution of the values of body posture features takes place after carrying two equal containers on the chest and back or one on the back. (3) The most unfavourable changes of the values of body posture features during carrying and restitution appear when the schoolbag is carried on the chest and dragged with right or left hand.
