Secular trends in body dimensions among young tennis players from 1992 to 2008
Aleš Filipčič, Bojan Leskošek, Nejc Šarabon, Tjaša Filipčič, 2012, original scientific article

Abstract: 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

Različni vidiki vrednotenja uspešnosti profesionalnih teniških igralcev
Andrej Panjan, Aleš Filipčič, Nejc Šarabon, 2013, original scientific article

Abstract: Cilj članka je predstaviti prve rezultate dolgoročno zasnovane študije, kjer obravnavamo tenis z vidika kakovostnih skupin profesionalnih igralcev, teniške uspešnosti posameznih držav in kontinentov ter kazalcev uspešnosti. Na temelju zbranih podatkov o ATP tekmovanjih in igralcih, uvrščenih do tristotega mesta na profesionalni jakostni lestvici v obdobju 1975-2008, smo ugotovili, da lahko igralce glede na število ATP točk razdelimo v pet kakovostnih skupin, in sicer na način, da so razlike med skupinami čim večje. Analiza sprememb v teniški uspešnosti držav in kontinentov kaže, da je v sedmih časovnih obdobjih prišlo do velikih razlik v odstotkih igralcev, ki zastopajo posamezen kontinent. V Evropi, Aziji in Južni Ameriki je teniška uspešnost v vzponu, v Severni Ameriki, Oceaniji ter Afriki pada. Povezanost med teniško uspešnostjo in številom ATP tekmovanj ter vrednostjo nagradnih skladov se znižuje. Kazalci uspešnosti so dovolj občutljivi, da ločujejo bolj in manj uspešne igralce. Profesionalni igralci so vedno bolj vsestranski in uspešni v vseh igralnih situacijah. Prve ugotovitve študije kažejo, da se tenis stalno spreminja in razvija, kar zahteva stalno spremljanje, sledenje ter iskanje novih trendov.
