Abstract
Cilj ovog randomiziranog, dvostruko slijepog, placebom kontroliranog istraživanja s ukriženim ustrojem bio je utvrditi akutni utjecaj kofeina na prosječni i vršni izlaz snage u testu na veslačkom ergometru kod ispitanika iskusnih u treningu sa otporom. Istraživanje je provođeno na uzorku od 25 muških ispitanika (dob ( aritmetička sredina ± standardna devijacija) 23 ± 2,0 godine, visina 181,5 ± 7,3, masa 83,2 ± 11,3) koji su kroz 3 dolaska u laboratorij prošli upoznavanje sa testiranjem, te testiranje izvedbe nakon konzumacije 6 mg/kg placeba (dekstroza) ili 6 mg/kg kofeina. Zadatak ispitanika je bio izvesti šest zaveslaja s maksimalnim ulaganjem sile i brzine na veslačkom ergometru uz prethodno zagrijavanje. Varijable koje su proučavane bile su prosječni izlaz snage (prosjek svih 6 maksimalnih zaveslaja) i vršni izlaz snage (najjači pojedinačni zaveslaj). U uvjetima konzumacije kofeina dobivena je statistički značajna razlika u vršnom izlazu snage u odnosu na placebo (p=0,02) dok je za prosječni izlaz snage konzumacija kofeina u odnosu na konzumaciju placeba rezultirala ne postojanjem statistički značajne razlike (p=0,19) iako se i tu u prosjeku postižu bolji rezultati. Zaključeno je kako kofein ima ergogeni učinak na vršni izlaz snage u kompleksnom motoričkom zadatku. Temeljem rezultata može se preporučiti konzumacija kofeina prije kratkotrajnih kompleksnih motoričkih zadataka u svrhu akutnih poboljšanja izvedbe, specifično, poboljšanja u izlazu snage.
Abstract (english)
The aim of this randomized, double-blind, placebo-controlled, cross sectional study was to determine the acute effects of caffeine on average and peak power output on a rowing ergometer in individuals experienced in resistance training. The study was conducted on a sample of 25 male subjects (age ( mean ± standard deviation) 23 ± 2,0 years, height 181,5 ± 7,3, weight 83,2 ± 11,3) who were through 3 visits to the laboratory passed familiarization with testing, and performance testing after consumption of 6 mg / kg placebo (dextrose) or 6 mg / kg caffeine. The task of the respondents was to perform six "all-out" strokes on a rowing ergometer with pre-heating. Variables studied: average power output (average of all 6 strokes), peak power output (strongest single stroke). In the conditions of caffeine consumption, a statistically significant difference was obtained in the peak power output in relation to placebo (p = 0.02), while for the average power output, caffeine consumption in relation to placebo consumption resulted in no statistically significant difference (p = 0,19) although on average better results are achieved here as well. It was concluded that caffeine has an ergogenic effect on peak power output in a complex motor task. Based on the results, caffeine consumption may be recommended prior to a complex motor task for the purpose of acute improvements in performance.
