Caffeine and sport: the timeline effect on ADP receptors

 Caffeine improves performance through the blockade of ADP receptors.

The human body answer is to increase the number of receptors.

In this setting how long do you deprive your body of caffeine to get the maximum effect of it during a race?

We don't know.

It is probably wise to introduce a 2-4 weeks window of caffeine before a race.
