Description
| - The purpose of this study was to determine the effect of different doses of caffeine on extending time to exhaustion in long-term endurance exercise. Using a placebo-controlled, double-blind crossover study design, 10 hobby male cyclists (30.3 ± 5.8 y; BMI = 23.5 ± 1.6, VO2max = 56.9 ± 6.6 ml x kg x min) completed three experimental tests. Each test consisted of 1-h steady-state cycling on static ergometer at 70% VO2max load immediately followed by graded exercise test to exhaustion (2.3 W x s). Either placebo or 0 or 7 mg x kg BM of synthetic caffeine with 0.5 l water and maximum of 0.5 mg x kg BM of carbohydrate gel were administered 70 minutes prior to the test. Total exercise time was significantly (p < 0.05) extended by the 7 mg x kg BM of caffeine compared with placebo. Significant (p < 0.05) extension of total exercise time was observed also by the 7 mg x kg compared with 2 mg x kg. No statistically (p = 0.97) significant differences were observed between 2 mg x kg compared with placebo.
