EFFECT OF TWO TAPERING METHODS ON INTERLEUKIN-6, CORTISOL AND PERFORMANCE IN ELITE MALE WRESTLER

The purpose of this study was to compare the effect of two types of tapering on interleukin-6(IL-6), cortisol and performance in elite male wrestler. After 4 weeks of progressive training, wrestler was randomly divided into three equal groups, 1-control group (N=10) continued performing progressive training for one week, 2-taper group 1 (N=10) continued with a 50% reduction in training volume for one week, 3-taper group 2 (N=10) continued with a 75% reduction in volume of training for one week. Plasma blood IL-6 and cortisol levels were assayed from analysis obtained via standard ELISA. Also general strength muscle was recorded as a performance test. All data were collected before and after progressive training and also after one week tapering period. Result: There were significant reduction IL-6 and cortisol levels among both tapering group with control group (P[< or =]0.05). There was significant reduction of IL-6 and cortisol levels among tapering 50% and tapering 75% after tapering period (P[< or =]0.05). Also there was significant increase in general strength muscle between tapering 75% and control group (P[< or =]0.05). Hence, one week tapering with 75% reduction in training volume after progressive training while the intensity kept high is effective strategy for reduction IL-6, and cortisol levels and also increase performance. It seems that higher reduction of training volume when the intensity kept high is a good strategy for wrestler before main competition.Original Abstract: Svrha ovog istrazivanja bila je usporediti ucinak dvije vrste koncentracije na interleukin-6 (IL-6), kortizol i izvedbu kod elitnih hrvaca. Nakon 4 tjedna progresivnog treninga, hrvaci su nasumce podijeljeni u tri jednake skupine, 1-kontrolne skupine (N=10) s nastavkom obavljanja progresivnog trening za jedan tjedan, 2-konus skupina 1 (N=10) s nastavkom ali uz smanjenje od 50% u volumenu treninga za tjedan dana, i 3-konus skupina 2 (N=10) s nastavkom ali uz smanjenje od 75% u volumenu treninga na tjedan dana. Plasma krvi IL-6 i kortizol razine su ispitane iz analize dobivenih standardnim ELISA postupkom. Takoder opca misicna snaga zabiljezenaje kao test izvedbe. Svi podaci prikupljeni su prije i nakon treninga i nakon tjedan dana. Rezultat: Bilo je znacajno smanjenje razina IL-6 i kortizola izmedu obje konusne skupine u odnosu na kontrolnu skupinu (P[< or =]0.05). Znacajno su smanjene razine IL-6 i kortizola izmedu 50% i 75% nakon analiziranog razdoblja (P[< or =]0.05). Tako
