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.
