Abstract. The objective of this research was to verify the relationship between biological markers of performance of elite judo athletes and performance in different physical fitness tests. Twenty-one judo athletes were involved in the present observational and correlational study. Dermatoglyphic variables and the 2D:4D digit ratio were considered as biological markers, while the physical fitness variables analyzed were body fat, maximal strength, muscular power, the aerobic and anaerobic profile, and performance in specific tests. The statistics involved canonical correlations and a multivariate technique. A high and significant canonical correlation was observed between groups of variables, the first expressed by 1=0.999 (p<0.0001) and the second by 2=0.997 (p<0.001). It appears that, beyond height and body mass, total ridge count, pattern intensity for fingers and 2D:4D had more canonical loading. The physical fitness component of the first canonical variable incorporated, with high intensity: the sum of skinfold thickness, the bench press one-repetition maximum (1RM), upper and lower body aerobic power. In the second canonical variable, physical fitness was composed of the squat 1RM, suspension time on the bar, the SJFT-index, and mean power during the upper body Wingate test. The data of this investigation showed the interdependence between biological markers of performance and physical fitness in high level judo athletes.

KANONIČKA KORELACIJA IZMEĐU BIOLOŠKIH MARKERA PERFORMANSE I FIZIČKE PRIPREMLJENOSTI KOD ELITNIH DŽUDISTA
Cilj ovog istraživanja bio je da se potvrdi odnos između bioloških markera performanse eltinih džudista i njihovih rezultata na različitim testovima za određivanje nivoa fizičke pripremljenosti. Ukupno je 21 džudista učestvovao u istraživanju. Dermatoglifijske varijable i odnos 2D:4D smatrani su biološkim markerima, dok su varijable za fizičku pripremljenost koje su analizirane bile telesna masnoća, maksimalna snaga, mišićna snaga, aerobički i anaeorobički profil, i rezultati postignuti na pojedinim testovima. Statistička obrada podataka obuhvatala je kanoničke korelacije i multivarijantnu tehniku. Visoka i značajna kanonička korelacija utvrđena je između grupa varijabli. Prva je izražena kroz 1=0.999 (p<0.0001) a druga kroz 2=0.997 (p<0.001). Čini se da su, pored visine i telesne mase, sveukupni broj brazdi, intenziteta otiska prsta i odnos 2D:4D imali veći kanonički uticaj. Komponenta fizičke pripremljenosti prve kanoničke varijable je obuhvatala, sa visokim intenzitetom: ukupnu sumu debljine nabora kože, duboki pretklon na klupici sa (1RM), aerobičku snagu gornjeg i donjeg dela tela. U drugoj kanoničkoj varijabli, fizička pripremljenost se sastoji od čučnja 1RM, vreme visa u zgibu, SJFT-indeks, i srednje vrednosti snage tokom Wingate testa za gornji deo tela. Podaci prikupljeni tokom ovog istraživanja pokazali su međusobnu vezu između bioloških markera performanse i fizičke pripremljenosti kod elitnih džudoista.
