Ninety-eight competitive tennis players (53 males, 45 females) of different age groups participated in the study. For validation, the adult male players completed three Hit & Turn tests, one on a clay court and two on a carpet surface, a tennis-specific ball machine test and an incremental treadmill run in a randomized order. A stronger correlation between maximal performance (r = 0.81, P < 0.01) and maximal oxygen uptake (r = 0.96, P < 0.01) was observed between the Hit & Turn test and the ball machine test, than between the Hit & Turn test and the treadmill test. For test-retest, we found a significant correlation between maximal performance on the same (r = 0.83, P < 0.01) and on different surfaces (r = 0.74, P < 0.01). During test evaluation, maximal performance was higher in males than in females (P < 0.01) and increased by consecutive age group in boys (P < 0.01) but not in girls (P = 0.97). In conclusion, Hit & Turn maximum test performance can be recommended as a valid and reliable indicator for tennis-specific endurance.

U analizu je bilo uključeno 1002 muškaraca i žena koji su prošli redovita testiranja slovenskog nacionalnog teniskog saveza te su bili pazicionirani na njihavoj rang listi u sezonama od 1993 do 2008. Odabir najvažnijih varijablia uz pomoć dvije automatske metode dao je slične rezultate, dok su se varijable odabrane od strane trenera bitno razlikovale. Dokazano je kako je uz pomoć klasifikacijskih metoda moguća dobra predikcija natjecateljske uspješnosti u uzrastima ispod 16 godina, dok je kod uzrasta starijih od 16 godina ta predikcija loša. Među regresijskim metodama, za razilku od linearne regresije koja je dala zadovoljavajuće rezultate, regresijsko drvo pokazalo se praktično neupotrebljivim. Automatske metode odabira najvažnijih varijabla morfoloških karakteristika i motoričkih sposobnosti pokazale su se superiornima u odnosu na metode odabira koje koriste teniski treneri. Ta je činjenica bila najviše istaknuta kod ženskih tenisačica i kod upotrebe metode linearne regresije. (Croatian) [ABSTRACT FROM AUTHOR]

The analysis included altogether 1,002 male and female tennis players who had undergone regular testing by the National Tennis Association and were positioned on the ranking list of the Slovene Tennis Association between the years 1993 and 2008. Selections of the most promising variables by means of the two automatic methods yielded similar results, whereas the selection performed on the basis of estimates made by coaches differed considerably. With regard to the analysis by means of classification methods, an accurate predictability of competitive performance for the age category younger than 16 years was observed, while the results of predictions for the age category older than 16 were poor. Among the regression methods, as opposed to the linear regression, which has yielded satisfactory results, regression trees served no useful purpose in practice. Automatic methods for identifying the most promising variables proved to be more successful than those of the coaches, which was most clearly noticeable with regard to the female tennis players and when linear regression was used.
