| Description |
This study is based on the results of the trans-sectional experiment, conducted during March, 2013/2014 school year with older preschool children (preparatory group) in the City of Niš (Serbia). The sample includes 49 respondents, of both genders, and was implemented in accordance with the principles of the Helsinki Declaration on the Rights of the Child. The main objective of the study was to determine the status of physical development of the older preschool children (preparatory), up 6+ to 7 years old, divided by gender in two sub-samples: boys (n=20), and girls (n=29). For this purpose, the basic morphological parameters were measured: BH (body height) and BW (body weight) as well as the BMI (Body Mass Index) was calculated, according to the formula and OMRON scale, proposed by the WHO (World Health Organization). The specific aim of this study was to determine possible gender differences (between sub-samples of boys and girls) in total, as well as intergroup differences, according to the type of physical activity (PA) in which the subjects were involved. Respondents of both genders were divided into three groups of elective activities, and a control group of children (without additional physical activity). The girls were involved in RG (rhythmic gymnastics), SW (swimming), PF (Physical Fitness) and Control group. The boys were involved in FB (football), JU (judo), SS (sports school) and the Control group. Based on the measured body composition parameters, the basic statistical data were calculated: MIN and MAX, Average, and Interval. The obtained results are presented in tables and graphs. A comparative analysis of the results was performed to estimate between groups differences (by gender), and within groups differences (by the type of preferred PA), separately in boys and girls, as well as determining possible contribution of individual physical activities to these differences. Due to the small size of sub-samples, estimated numeric walues are presented in the form of the tables and histograms.
