Nine subjects (8 male and 1 female; age: 21±1 years; VO2max: 57.9±l.5ml kg-1min-1) performed two 9-min tests on a treadmill at a running velocity eliciting 90% of their VO2max, 60 min after ingesting either a placebo capsule (PLAC) or a capsule containing a caffeine dose of 5 mg (kg body mass)-1 [CAFF]. The mean values of ΔVO2 were significantly lower in CAFF than in PLAC (83±31 ml min-1 vs. 167±26 ml min-1, respectively; p<0.05). These findings suggest that the ergogenic effect of caffeine in a high-intensity endurance exercise shown in previous research may be partly mediated by a possible attenuation of the VO2 slow component.
