Abstract
[b]The goal of the researches[/b]. To find out what is the function of the particular morphological age components in diversification of the individual components of the physical activity according to the health convention and to describe, in the main periods of ontogenesis, the effectiveness limit of the relativeness methods of the physical activity convention’s basic components using the traditional formula estimating the morphological age.[b]The subject[/b]. Among 5229 girls at the age of 8–17, tested in 1996–2005 in Malopolska region, 150 individuals in three age groups of 8–9, 12–13 i 16–17 were chosen. In total, the results of the basic components of the physical activity elements (morphological, skeletal-muscular and circulatory-respiratory) deriving from 900 female individuals from primary and secondary schools of the Polish regions (Malopolska, Podkarpacie, and Świetokrzyski) were taken into consideration. Such selected community (each 150 individuals) was divided into three groups (each 50 individuals). The division criterion was the morphological age, which was the biological development measurement. To estimate the statistical analysis only subjects from two extreme variables ranges were considered. The other numbers of the tested located close to the median were not included in further statistical analysis.[b]Methods[/b]. In the age groups and the extreme fractions of the tested, chosen according to the morphological age, the SD value of the physical activity components enclosed in H-RF was estimated. It enabled to normalize the 0 and 1 level of the intergroups differences and to describe their statistical significance. To estimate the strength between independent variable (the morphological age) and dependent variables (the physical activity of H-RF components) Pearson’s correlation and part-correlation methods were used. The significance of the intergroups differences and correlation coefficients were tested by t-Student test. The arithmetic means, Pearson’s correlation and part-correlation coefficients’ values were described as the statistical variables with at least 5% (p < 0,05) importance level.[b]The results[/b]. The part-correlation was extremely helpful in claiming there was a great importance of the calendar age in determining the morphological age. The body mass age and body height age, as well as the calendar age, had a great influence on the numerical value of the tested female groups. The morphological age influenced mostly the kinetic and functional components especially among the individuals in the junior and puberty period.[b]Summary[/b]. The results of the advanced statistical method justify not always appreciated need of introducing the calendar age to the mathematical formula describing the biological age. The morphological age complying the body mass age, body height and the life length (the calendar age), can be a factor deducting the biological development from the kinetic and functional components of the physical activity in the health convension. From the adolescence period the morphological age influnece on described parameters suppresses.
