Sažetak

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 kategorije: 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 uzrasta kadeta.
