Caffeine (Caf) ingestion increases plasma
epinephrine (Epi) and exercise endurance; these results are frequently
transferred to coffee (Cof) consumption. We examined the
impact of ingestion of the same dose of Caf in Cof or in water. Nine
healthy, fit, young adults performed five trials after ingesting
(double blind) either a capsule (Caf or placebo) with water or Cof
(decaffeinated Cof, decaffeinated with Caf added, or regular
Cof). In all three Caf trials, the Caf dose was 4.45 mg/kg
body wt and the volume of liquid was 7.15 ml/kg. After 1 h of rest, the
subject ran at 85% of maximal O 2
consumption until voluntary exhaustion (~32 min in the placebo and
decaffeinated Cof tests). In the three Caf trials, the plasma Caf and
paraxanthine concentrations were very similar. After 1 h of rest, the
plasma Epi was increased ( P |

plasma Epi was increased ( P < 0.05)
by Caf ingestion, but the increase was greater
( P < 0.05) with Caf capsules than
with Cof. During the exercise there were no differences in Epi among
the three Caf trials, and the Epi values were all greater
( P < 0.05) than in the other
tests. Endurance was only increased
( P < 0.05) in the Caf capsule trial; there were no differences among the other four tests. One cannot extrapolate the effects of Caf to Cof; there must be a component(s) of
Cof that moderates the actions of Caf.
