Caffeine lowers perceptual response and increases power output during high-intensity cycling

The mechanisms by which caffeine exerts its ergogenic effect are unclear, but in long-duration activity a reduced perception of effort is frequently cited as a result of caffeine ingestion. In high-intensity exercise, caffeine is also ergogenic but its effects on effort-perception have not been reported prior to this study. This paper showed that caffeine’s ergogenic properties during constant-load, short-duration, heavy activity coincide with a reduced perception of effort, suggesting a common effect of caffeine ingestion during short- and long-duration exercise. Hughes assisted with the design of the study, the data collection and the editing of the manuscript.

Hewlett, Paul; Smith, Alyson (John Wiley & Sons Ltd., 2006-03-01)Rationale The effects of caffeine on mood and performance are well established. One explanation of these effects is that caffeine removes negative effects induced by prior caffeine withdrawal. This was tested here by ...
Effects of Reapeated Doses of Caffeine on Performance and Alertness: New Data and Secondary Analyses Hewlett, Paul; Smith, Andrew (Wiley, 2007)Rationale The effects of caffeine on mood and performance are well established. Some authors suggest that caffeine merely reverses effects of caffeine withdrawal rather than having direct behavioural effects. It has also ...
