Relations of Morphological and Motor Skill Predictors in Children Using Linear and Nonlinear Regression Model : Masters Thesis

Cilj ovog rada je identificirati i objasniti morfološke i motoričke prediktore potkožnog masnog tkiva kod djece korištenjem linearnog i nelinearnog paraboličnog modela. U skladu s ciljem na uzorku od 34 ispitanika proučavalo se relacija izdržaja u visu, tjelesne mase i nabora nadlaktice. Korištenjem linearnog i nelinearnog paraboličnog modela povezanosti višestrukom regresijskom analizom ispitala se promatrana povezanost. Rezultati ukazuju da je kod nelinearnog paraboličnog modela uočena značajna povezanost između tjelesne mase i nabora nadlaktice, te izdržaja u visu i nabora nadlaktice, a kod linearne metode All effects da postoji značajna povezanost između navedenih varijabli, dok metoda Forward stepwise anulira povezanost izdržaja u visu s naborom nadlaktice. Rezultati ukazuju na mogućnost programiranja efikasnih trenažnih procesa i to s ciljem transformacije nekih karakteristika i sposobnost utjecanja na poboljšanje drugih.The aim of this paper is to identify and explain the relations of height endurance, body weight and upper arm fold. The study was done on 34 children. A nonlinear correlation model and a multiple regression analysis were used and the data were processed in the program Statistica 13. Tables and graphs show that there are statistically significant correlations between predictors and criteria. In the kinesiological interpretation, a certain correlation is found between the progress in endurance in height and that a decrease in body weight and an increase in endurance in height will lead to a decrease in the folds of the upper arm, which was the criterion. However, one analysis shows that endurance in height does not have significant correlation on the upper arm fold. It is important to note that a professional program of effective training process can lead to a change in some characteristics and abilities that can influence the improvement of others
