The Restitution of the Body Posture Values in the Sagittal and Transversal Plane after Carrying a Schoolbag on the Chest and its Correlations with Physical Activity Among 7-Year-Old Children of Both Sexes |Biomedgrid

Introduction: The analysis of the student's environment is a set of stressors in the field of human ecology. Material and Method: The body posture tests were carried out in a group of 65 students aged 7 years, using the moiré projection method in 4 positions: 1st-habitual posture, 2nd-posture after a-10-minute of axial symmetrical loading, 3rd-one minute after the load removal, 4th-two minutes after the load removal. Physical fitness was measured with the Sekita test, completed by an endurance test. Results: The significance of differences between 1st and 3rd, 1st and 4th, 2nd and 3rd as well as 3rd and 4th measurement were analysed to determine the restitution of the features values after loading and their correlation with physical fitness. Conclusions: a) After the load removal of carrying school supplies from the chest, there was an incomplete restitution of almost all values of the diagnosed posture features after the first and second minute. b) The relationships between the examined determinants of physical fitness and the restitution of the values of posture features are much more frequent among boys than girls. The most frequent correlation was between endurance and speed among boys, whereby agility, strength and overall fitness appeared among girls. Restitution of the values of posture features that most often showed relationships with physical fitness features among boys were asymmetry of the pelvis tilts to the left (KSM-) in the transversal plane, and convexity of the lower angles of the shoulder blades, where the left one was more convex (UB-), and, asymmetry of verticality of the torso bend in the sagittal plane (KPT-) and the sum of the piecemeal angles (Delta), among girls. c) There should be actions taken to promote a healthy lifestyle for children, including physical education.
