| Popis | The aime of our contribution 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 the randomized, crossover, double-blind study. Duringthree daysparticipationcompleted three identical experimentaltests (60 min cycling time trial on 70% VO 2max followed by test to exhaustion). Three experimental meals - combination of 500 ml water, gel supplement and specific dose of caffeine: placebo (PLA, no caffeine), CAF2 (2 mg/kg BW) and CAF7 (7 mg/kg BW) were administered 45 min prior to the start of the experimental tests. Results show significantdiferences (0,018 and 0,019) between MPO PLA and MOP CAF7 and maximal MPO CAF2 and MOP CAF7 (p=0,05) only in group sub-elite cyclists. These findings indicate that caffeine intake at recommended levels is not associated with improved performance in proffesional level cyclist. |
