Abstract
The goal of this transverse research was to establish the correlations between morphological characteristics, and identifying the latent morphological structure. In the morphological space, a group of 12 standard anthropometric variables was measured. The sample encompassed 158 female subjects, aged 12 to 14 years, from volleyball clubs of the Kolubara-Macva Inter regional Serbian league. Statistical data analysis was conducted using Pearson's coefficient of correlation and Principal component analysis (PCA). Results from the correlation analysis showed statistically significant linear correlations in almost all anthropometric variables of female U14 volleyball players. Using the method of Principal Component Analysis (PCA), together with the Kaiser-Guttman criteria and Varimax rotation, a threecomponent model was extracted which comprised 83,35% of proportion of the total variance of manifested anthropometric variables. This model was structured by the hypothetical factors with their characteristic roots (ƛ > 1), which were interpreted as: longitudinal skeleton dimensionality (F1), body volume and body mass (F2), and subcutaneous fat tissue (F3). The limitations of this study were discussed, as well as recommendations for future longitudinal research. Objectively, an insufficient amount of conducted empiric studies so far presents a motive for other authors to establish a relationship between morphological landmarks and defining the build of the morphological space in preadolescent population of female volleyball population.
Highlights
The morphological characteristics, as a compo nent of the anthropometric status, comprise a biologic and physiologic basis that elicits the exposition of anthropometric measures
Based on the common characteristics of manifested variables in the condensed structural matrix of principal components, only three well informative are kept, together with latent dimensions in zero inter-correlations between each other, which relevantly explain about 4/5 of the variability proportion. This points to the validity of the applied sample of variables and objectivity in the measure which varies in allowable limits, as well as the possibility that in the analysis, three latent dimensions instead of 12 manifested variables can be used, with a minimal loss of 16.65% of information, which are most likely caused by a lack of research of the specificity-factor
Longitudinal skeleton dimensionality as the optimal sign of growth of the organism of volleyball players, and it is a result of a complex process of ontogenetic development and the act of biotic and abiotic latent dimensions in a specific environment
Summary
The morphological characteristics, as a compo nent of the anthropometric status, comprise a biologic and physiologic basis that elicits the exposition of anthropometric measures. By factor-influenced procedures, they can transform into latent morphological dimensions. Information regarding body constitution can be a relevant indicator of an individual’s health status, and can serve in evaluation of their rate of growth and development, which is shown by Popovic in his research (2008). By analyzing the multidimensional morphological space, the fact that development of some of latent dimensions is substantially defined by the individuals’ structure both endogenously and exogenously stipulated factors is something that should be kept in mind
