20.500.12556/RUP-3756 Secular trends in body dimensions among young tennis players from 1992 to 2008 Several studies have examined both physical characteristics and fitness of children and youth. The aim of the study was first, to find the tendency of changes in selected morphological characteristics of young male and female tennis players of various ages in the periods 1992-2000-2008; and second, to find the changes in selected variables of young tennis players and to compare them with the results of boys and girls of same age from normal school population. Sample of variables included body height, body weight and body mass index (BMI). Multivariate analysis of variance revealed statistically significant differences in all main factors (group, age, gender and period) and additionally in interactions group*period, group*gender and age*gender. Univariate analysis of variance revealed statistically significant differences in body height and BMI between the groups of tennis players and the same age school population for both sexes and between three age groups (12-13 years, 14-15 years, 16-17 years) for body height, body weight and BMI. Differences between the sexes indicate statistically significant differences only in variables body height and weight. Changes in the observed morphological characteristics point to the increase in body height, body weight and BMI values in both school population and young tennis players tennis young players body weight body hight BMI secular trends tenis mladi igralci teža višina BMI true false false Angleški jezik Španski jezik Delo ni kategorizirano 2013-10-15 12:09:08 2013-10-15 12:09:08 2024-03-01 12:11:44 0000-00-00 00:00:00 2012 0 0 str. 1558-1568 no. 4 Vol. 30 2012 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 0717-9367 796.342.012.1 2377939 http://www.scielo.cl/pdf/ijmorphol/v30n4/art47.pdf 1 https://repozitorij.upr.si/Dokument.php?lang=slv&id=3756 Univerza na Primorskem 0 0 0
