dc.description.abstract-1To determine the effects of low doses (1, 2, and 3 mg·kg) of caffeine on cycling performance, differentiated ratings of perceived exertion (D-RPE), quadriceps pain intensity, and metabolic responses to cycling exercise, 13 trained athletes cycled on a .stationary ergometer for 15 min at 80% VO2peak, then completed a 15-min performance -1ride 60 min after ingesting caffeine or placebo. Work production (kJ·kg) during this ride was the performance outcome measure. D-RPE, pain ratings, and expired gas data were obtained every 3 min, and blood lactate concentrations were obtained at 15 and 30 min. Caffeine had no effect on work production, D-RPE, pain or most metabolic variables. In conclusion, low doses of caffeine do not affect cycling performance or perceptual responses to exercise. Athletes seeking performance benefit should ingest larger doses for which advantageous ergogenic and perceptual effects have been established.
