Abstract. The aim of this study was to establish the differences in lactate and glucose wrestling fight levels for the age categories of boys, cadets and juniors. Also, the aim was to explain lactate and glucose curves and adaptive changes caused by training. The study was conducted on a sample of 30 young wrestlers. The sample was divided into three age categories: boys n=10, cadets n=10 and juniors n=10. Every participant wrestled one match according to the FILA rules. Capillary blood samples were taken for the analysis of blood lactate and glucose before the fight, after each round and after 5 minutes of sedentary rest. The results confirmed that there are no significant differences in blood lactate and glucose dynamics between cadets and juniors. Furthermore, boys have a statistically different lactate level after the first, the second and the third round (p<0,01) than cadets and juniors. Boys also have a statistically different glucose level after 5 minutes of sedentary rest (p<0,001). Lactate dynamics and also glucose dynamics lead to the same conclusion: the best age to start with anaerobic diagnostics through lactate and glucose dynamics is the cadet age.

DINAMIKA POTROŠNJE LAKTOZE I GLUKOZE TOKOM RVANJA – RAZLIKE IZMEĐU MLAĐIH KATEGORIJA, KADETA I JUNIORA
Cilj ovog istraživanja bio je da se odrede razlike u laktozi i glukozi tokom rvanja za uzrasne kategorije mlađih rvača, kadeta i junior. Takođe, cilj je bio da se objasne krive laktoze i glukoze i adaptivnih promena koje su posledica treninga. Istraživanje je sprovedeno na uzorku od 30 mlađih rvača. Uzorak je podeljen na tri starosne kateogrije: mlađe dečake n=10, kadete n=10 i juniore n=10. Svaki ispitanik je učestvovao u jednom meču u skladu sa pravilima FILA. Uzorci kapilarne krvi uzeti su od učesnika radi analize laktoze i glukoze u krvi pre meča, nakon svake rudne i pet minuta nakon mirovanja. Rezultati su potvrdili da nije bilo statistički značajnih razlika u pogledu dinamike laktoze i glukoze u krvi između kadeta i juniora. Dalje, mlađi dečaci imaju statistički značajne razlike u nivou laktoze nakon prve, druge i treće runde (p<0,01) u odnosu na kadete i juniore. Mlađi dečaci takođe imaju statistički značajne razlike u nivou glukoze nakon petominutnog odmora (p<0,001). Dinamika laktoze i glukoze dovodi do istog zaključka: najpogodnije godine za početak anaerobne dijagnostike putem laktoze i glukoze je uzrasat kadeta.
