Abstract. The aims of this study were: a) to identify the anthropometric characteristics and agility abilities of 14 year-old elite male basketball players, and b) to investigate the influence of anthropometric characteristics on agility test results. The following 11 anthropometric variables were measured on a sample of 50 young basketball players, age 14,: four longitudinal measures, two transversal measures, body mass, four circumferences, six skinfolds and, also, 2 derived variables: the body mass index – BMI, and sum of skinfolds – SUM SKF (predictor variables). In addition, the participants carried out 3 agility tests: the agility T-test, zigzag agility drill and 4x15 m agility run (dependent variables). For the assessment of the influence of predictor variables on the dependent variables, a regressive analysis, the Stepwise method, was applied. The results of three regression analyses indicate a moderate, but significant influence of anthropometric variables on agility test results. Longitudinal and transversal measures, body mass, and circumferences had no influence on agility tests results. Only SUM SKF had a significant influence. This variable was extracted during the first step in all three regression analyses, and the circumference of the mid-upper-arm was extracted during the second step in the case of the dependent variable zigzag agility drill.

UTICAJ ANTROPOMETRIJSKIH KARAKTERISTIKA NA AGILNOST MLADIH ELITNIH KOŠARKAŠA UZRASTA OD 14 GODINA
Ciljevi ove studije su bili: a) identifikovati antropometrijske karakteristike i karakteristike agilnosti mladih elitnih košarkaša uzrasta od 14 godina, b) ispitati uticaj antropometrijskih karakteristika na rezultate u testovima agilnosti. Na uzorku od 50 mladih košarkaša, uzrasta od 14 godina, izmereno je 11 antropometrijskih varijabli: četiri longitudinalne mere, dve transverzalne mere, telesna masa, četiri obima, šest kožnih nabora, kao i dve izvedene varijable: indek telesne mase – BMI I suma kožnih nabora – SUM SKF (prediktorske varijable). Takođe su primenjena i tri testa agilnosti: test agilnosti T-test, test cik-cak u reketu and test trčanje 4x15 m (zavisne varijable). U određivanju uticaja prediktorskih varijabli na zavisne varijable primenjena je regresiona analiza - Stepwise metod. Rezultati triju regresionih analiza govore o umerenom ali značajnom uticaju antropometrijskih varijabli na rezultate u testovima agilnosti. Longitudinalne i transverzalne mere, telesna masa i obimi, nemaju značajan uticaj na rezultate testova agilnosti. Samo varijabla SUM SKF ima značajan uticaj i to negativan. Ova varijabla je ekstrahovana u prvom koraku u sve tri regresione analize, dok je kod zavisne varijable cik-cak u reketu u drugom koraku ekstrahovana i varijabla obim nadlaktice.
