title: The biological age of prepubescent and pubescent children with low and high motor efficiency.
abstract: The aim of the study was to analyze the relations between some criteria of the biological age (growth age, biological proportional age) and motor efficiency in school-aged boys and girls (8-9 and 12-13 years old) with considerably above-average and considerably below-average total score of the test battery UNIFITTEST (6-60). The growth age results of 8 chosen groups (17-25 individuals in one group) showed that classifying the selected individuals into the normative height bands was in no relation to their age, sex or level of motor efficiency. As for the height-weight proportionality, the older the individuals were, the more of them belonged to the bands with relatively bigger weight. Analyzing the results of the biological proportional age, we did not find any significant differences between the groups of identical sex, age and different motor efficiency. Boys and girls with either low or high motor efficiency were mostly biologically average and biologically accelerated in the growth and development.
