Morphological characteristics and motor skills are closely related and jointly take part in solving motor tasks. Based on morphological characteristics, it is possible to determine the nutritional status of children and adolescents, which represents one of the more important indicators of health, psycho-physical abilities and the potential for normal growth and development. In addition, it may also serve as a leading factor determining their future state of health. The onset of obesity during childhood is related to a series of psycho-social problems, the loss of confidence, and depression. There are 1.7 million people in the world who belong to the atrisk group for obesity, while 310 million are already obese. In the region of Europe 50% of adults and 20 – 30 % of children and adolescents have excess levels of body mass. The prevalence of obesity among children and adolescents in Serbia is estimated to be at 19% and in constantly on the increase. The basic cause of obesity i...s the disproportion between dietary intake and energy expenditure. The subject matter of this research were the morphological characteristics and motor skills of younger school-age boys of various levels of nutritional status, while the research problem was to determine whether there are any differences in the morpho-motor skills of younger school age boys in terms of their nutritional status, and whether there was any significant dynamics of changes in the morpho-motor skills of younger school-age boys of various levels of nutritional status. Based on the defined subject matter and the research problems, we defined the goals of the research which refer to the determination of the differences in morpho-motor skills, as well as the dynamics of changes of the morphological characteristics and motor skills of younger school-age boys depending on their nutritional status. Based on the defined subject matter, research problem and set goals, we formulated three general hypotheses and ten sub-hypotheses which refer to the existence of statistically significant differences in the morpho-motor skills of young school age boys depending on their nutritional statues, as well as the existence of statistically significant dynamics of changes in the morphological characteristics and motor skills of young school age boys of various nutritional status. The sample of participants consisted of 1164 boys aged 7 to 10. The sample was divided into 4 sub-samples based on their age, as well as into 3 groups depending on their nutritional status (normal body mass levels, overweight and obese individuals). The nutritional status of the boys was determined based on the values of their BMI. The morphological characteristics were determined by measuring four morphological dimensionalities, while for the determination of the level of motor skills we used motor tests for the evaluation of explosive strength, coordination, and speed. The data were processed using the statistical program SPSS 21.0. For all of the data we calculated the parameters of descriptive statistics, and in order to determine the differences between the groups we used a one-way ANOVA and the LSD Post Hoc test. In order to determine the dynamics of changes in the increasing or decreasing continuum we used a trend analysis. All of the hypotheses were partially or completely accepted. The study has indicated the dynamics of changes in morpho-motor skills and at the same time indicated the differences in the morphological characteristics and motor skills of young school age boys, aged 7 to 10, depending on their nutritional status. The most balanced growth and development was noted for boys who were, based on their BMI, classified as belonging to the group of participants with normal weight. These data support the need to fight obesity, primarily through an increase in physical activity among young school age boys.
