Caffeine ingestion attenuates the Vo2 slow component during intense exercise

The purpose of this study was to analyze the effects of caffeine ingestion on the slow component of oxygen uptake (ΔVO2) during high-intensity endurance exercise. 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...
