Abstract
The aim of this research was to examine the influences of specially programmed physical education lessons on biomotor
development in boys, as well as the influence of those changes on relations between the set of morphological and motor
variables and athletic variables for the assessment of sprint and throw abilities. For this purpose, an overall sample of
325 primary school first grade pupils from the city of Split area, aged 6–8 years, was divided into control group of subjects
(N=140) attending regular physical education lessons and experimental group attending specially programmed
lessons based on athletics, sports gymnastics and games elements as well as on general preparatory exercises. The relations
between the predictor set of variables composed of 4 morphological measurements and 6 motor tests with the criteria
of sprint and ball throwing were established by the regression correlation analysis at the beginning and at the end of
the academic year. Both groups of subjects achieved positive quantitative resultant shift between the two points of measurements,
whereas this shift was more significant in the experimental group in relation to the control group, especially in
motor abilities coordination of flexibility, movement frequency and of explosive, repetitive and static strength. The number
of significant predictors for criteria variables of sprint and ball throwing increased in the final measurement in relation
to the first one in both groups of subjects. While in the control group the best results predictor in sprint were the motor
abilities of explosive strength and trunk strength, the best results predictor in sprint in the experimental group were
coordination, trunk strength, flexibility and explosive strength. As far as the morphological characteristics are concerned
muscle mass has a positive and body mass a negative effect on the sprint result. The best results predictor in ball throwing
are explosive strength and trunk strength which, in the experimental group of pupils are additionally followed by coordination
development as well as the overall body mass development. By comparison of these and the earlier obtained
results, a new work model for the disciplines of sprint and throws within the athletic sport school, has been proposed.
