Via the NY Times Well Blog, an explanation of “how chocolate can help your workout:”

Mice given twice daily doses of epicatechin, a purified form of a flavanol found in cacao, were able to run longer than those given just water. But, of course, mice are not people, and processing cacao into chocolate can diminish or even destroy the epicatechin contained within.

Still, small amounts of dark chocolate could be helpful!
