THE EFFECTS OF PROGRAMMED TRAINING ON CHANGES OF MORPHOLOGICAL CHARACTERISTICS IN SEVEN-YEAR-OLDS

The study was performed with the aim of determining the effects of additional 9-month programmed soccer training on changes of morphological characteristics in boys. The sample consisted of 90 seven-year-olds, divided into an experimental (N=40) and a control (N=50) group. The experimental group included subjects who, in addition to regular physical education classes, also had three training units per week of additional training during nine months, whereas the control group included subjects who attended only regular physical education classes. The variable sample for assessing morphological characteristics consisted of 14 standard anthropometric measures. Based on the obtained results of discriminant canonical analysis in the final measurement it is clear that measures of body voluminosity are more prominent in the experimental group, whereas measures for assessing adipose mass are more prominent in the control group. From the analysis of changes between the initial and the final measurement, it is inferred that additional training, in addition to physical education classes, prevented the accumulation of subcutaneous adipose tissue in the experimental group. When analysing the differences in means of the results from the initial to the final measurement it can be noticed that in the experimental group measures of transverse dimensionality of the skeleton were significantly more increased and body mass and subcutaneous adipose tissue were reduced in relation to the control group. The results indicate that the additional programmed training, as opposed to just regular physical education classes, by applying specific operators, led to greater changes of morphological characteristics, which is manifested in skeleton development, reduction of adipose tissue and increased muscle tissue.
