Abstract
Children’s sprinters running differs from the adults’ one primarily in their motoric abilities, anthropometric characteristics,
physiological and biochemical characteristics, as well as psychological and sociological characteristics. This
research’s aim was to examine the infl uence of anthropometric characteristics on kinematic parameters of children’s
sprinter’s running. The sample of variables consisted of variables which determine anthropometric characteristics (14
anthropometric characteristics) and of 5 kinematic parameters’ variables of sprinter’s running. Kinematic parameters of
sprinter’s running in the phase of maximal speed have been collected by applying the Optojump technology (Microgate,
Italy) and the sprinter’s running times were measured every 5 meters on a 50 m lap. The results obtained from the multiple
regression analysis between the group of anthropometric characteristics and the 50 m running results indicate that
the percentage of fatty tissue is a statistically signifi cant variable with boys, while the same variable with girls is near the
limit of statistical signifi cance. In the factor structure of anthropometric characteristics two factors have been set apart
with boys and three with girls. The fi rst factor set apart with both boys and girls is the factor of body voluminosity, the
second factor with boys is the factor of longitudinal dimensionality, while with girls it is the factor of fatty tissue quantity.
The factor of longitudinal dimensionality is the third girls’ factor. For most variables a negative correlation has been
determined with a higher percentage of fat or a higher quantity of subcutaneous fatty tissue with both boys and girls. Boys
having a lower quantity of subcutaneous fatty tissue achieve better results in 50 m running, they have a shorter duration
of contact with the pad, a longer duration of the fl ight phase and a longer step length when compared to boys with a
higher quantity of subcutaneous fatty tissue. Boys with a bigger body muscular mass achieve a shorter duration of the
contact, a longer duration of the fl ight and a longer step length. Girls who have a lower quantity of subcutaneous fatty
tissue achieve a better 50 m running time, have a shorter duration of contact with the pad and a longer step length. It has
been established that taller boys have a longer step length, and longer feet signifi cantly infl uence the longer duration of
contact with the pad and the lowering of the step frequency.
