Caffeine intake enhances endurance performance in sub-elite but not in elite athletes

Popis výsledku v původním jazyce

The aim of the paper is to evaluate the influence of caffeine (CAF) ingestion on maximal power output (MPO) during endurance performance. Two groups of men ? 10 sub-elite cyclists and 8 elite cyclists completed a randomized, crossover, double-blind study. The participants completed three identical experimental tests (60min cycling time trial on 70 % VO2max followed by test to exhaustion). Three experimental meals - combination of 500ml water, gel supplement and specific dose of CAF: placebo (PLA, no caffeine), CAF2 (2 mg/kg body weight (BW)) and CAF7 (7 mg/kg BW) were administered 45min prior to the start of the experimental tests. The mean MPO during expeerimental test in sub-elite cyclist, but not in elite, was significantly enhanced following caffeine ingestion. These findings indicate that caffeine intake at recommended levels is not associated with improved performance in professional level cyclist.
