Spolne diferencijacije morfološkog i posturalnog statusa učenika nižih razreda osnovnih škola
Sexual Differentiation of Morphological and Postural Status of Lower Grade Primary School Students

Summary/Abstract: A system of fifteen variables (7 morphological and 8 variables for assessing postural status) was applied to a sample of 284 male and female students from the first to the third grade of primary school, with the aim of determining the differences between boys and girls. The results showed that there were statistically significant differences between the examined samples in the following morphological variables: in the first class (body weight and skin fold of the triceps), in the second class (body height, body weight, skin fold of the triceps and skin fold of the biceps) and in third grade (body height, skin fold of triceps, skin fold of back, skin fold of biceps, and skin fold of lower leg). Statistically significant differences in the variables for assessing postural status exist in the following variables: in the first grade (head posture, shoulder posture, shoulder posture, chest shape and leg shape), in the second grade (shoulder posture, chest shape, and spinal deviation in frontal plane) and in the third grade (deviation of the spinal column in the frontal plane, holding the anterior abdominal wall and the shape of the legs). Based on the obtained results, it can be concluded that in the younger school-age in morphology there is a significant sexual dimorphism and with it in connection with the change of postural status.
