Sažetak
Cilj istraživanja je bio da se utvrdi i uporedi nivo laktata u krvi seniora rvača, u odnosu na rundu u kojoj su završavali svoje finalne mečeve na zvaničnom prvenstvu države u rvanju grčko-rimskim stilom. Istraživanje je sprovedeno na 20 rvača, finalista državnog prvenstva Srbije. Takmičari su bili podeljeni u tri grupe prema kriterijumu u kojoj rundi su osvojili meč; G1 = 8, G2= 6 i G3 = 6. Procena laktata se vršila nakon zagrevanja, kao i u trećem minutu nakon završetka meča. Razlike između 3 grupe rvača su utvrđene primenom dvosmerne ANOVE i Fišerovovog LSD testa, dok je statistička značajnost podešena na p < 0,05. Vrednosti laktata dobijenih nakon zagrevanja između 3 grupe rvača su bile slične, dok su vrednosti laktata nakon meča kod rvača koji su osvojili meč posle treće runde pokazali znatno viši nivo laktata u odnosu na rvače koji su osvojili posle prve (7,45 mmol / l; p <0.001), ili druge runde (4,48 mmol / l; p = 0,014). Blizu statističke značajnosti su se našle vrednosti laktata rvača koji su osvojili meč nakon prve ili druge runde (2,97 mmol / l; p = 0,06). Rvači koji su finala završavali nakon treće runde su akumulirali i veće vrednosti laktata u krvi u odnosu na rvače koji su finala završili nakon prve ili druge runde, što bi moglo ukazivati na to da su ovi sportisti trenirani na visokointenzivni rad.
Abstract
The aim of the study was to determine and compare blood lactate levels by the round in which the senior wrestler ended the match in an official national Greco- Roman wrestling competition. The study was carried out on a sample of 20 male wrestlers, finalists of the national competition of Serbia. They were divided into three groups according to the round in which the athlete won the match: G1=8, G2=6 and G3=6. Lactate assessment was provided at two points; after the warm-up, and three minutes after the final match ended. The two-way ANOVA and Fisher's LSD statistic were used in order to compare the differences between the three groups (wrestlers who won after the first, second or third round). The level of statistical significance was set at 0.05. The results of the lactate values reported for the three groups of wrestlers after the warm-up was similar, whereas, after the match, the wrestlers who won after the third round showed significantly higher lactate levels compared to athletes who won after the first (7,45 mmol/L; p<0,001) or second round (4,48 mmol/L; p=0,014). The lactate values of wrestlers that won after the first or second round were close to significance (2,97mmol/L; p=0,06). Wrestlers that won their match after the third round accumulated higher lactate levels compared to those who won after the first or second round, indicating that these athletes seem to be trained to work at high intensity.
