Abstract

S obzirom da ne postoje istraživanja koja ispituju direktni utjecaj kofeina na plank test cilj ovog istraživanja je bio ispitati taj učinak kao test za izdržljivost i stabilnost te uz to testirati eksplozivnost putem skoka u dalj s mjesta, agilnost putem T – testa, ispitati postoji li utjecaj na percepciju napora nakon ingestije kofeina (RPE skala) te utječe li uobičajena konzumacija kofeina na sportsku izvedbu. Izvor kofeina korišten u istraživanju je energetski napitak Red Bull Sugarfree, a doze su 0 (placebo), 3 i 6 mg kg-1. Ispitanici su 16-ero mladih rekreativnih sportaša u dobi 18 do 35 godina. Metode za ispitivanje uobičajenog dnevnog unosa kofeina su trodnevni dnevnik prehrane i FFQ. Kofein (6 mg kg-1) značajno poboljšava izvedbu plank testa i skoka u dalj s mjesta u odnosu na placebo, a ne utječe na T – test i percepciju napora.

Abstract (english)

Considering there are no studies dealing with direct effect of caffeine on the plank aim of this study was to examine this effect (endurance and stability). The aim was also to examine explosivity (standing jump test), agility (T – test), examine is there any effect on perception of exertion after caffeine ingestion (RPE scale) and does habitually caffeine consumption affect sport performance. The source of caffeine is energy drink Red Bull Sugarfree, doses are 0 (placebo), 3 and 6 mg kg-1. Respondents are 16 young recreational athletes aged 18 to 35. Methods for testing habitually daily intake of caffeine are three-day diet diary and FFQ. Caffeine (6 mg kg-1) significantly improves performance of plank and the standing jump test in comparison with placebo, and caffeine does not affect the T - test and perception of exertion.
