Comparison of different regression models between coordination and selected variables of anthropological status

The aim of this study was to apply and compare linear, parabolic and logarithmic regression models between coordination as criteria and the selected variables of anthropological status. The subject sample included 40 male fourth grade primary school pupils (age 10.3±0.5 years) who were measured in the following variables: obstacle course backwards (MPOL), seated straddle stretch (MPRR) and triceps skinfold (ANN). All the applied regression models indicate a positive correlation between the ANN variable and the MPOL variable, with the MPOL variable being negatively scaled. In the parabolic model, the regression parameter of ANN variable, although non-significant, has negative sign. Also the MPRR variable has a negative coefficient only in the parabolic model, more precisely in the linear term, while it has a positive coefficient in all other models. Finally, the results indicate the fact of complex and non-linear correlations between the selected variables and point to the necessity of development and application of non-standard methodological tools as a very important aspect of kinesiological science.
