Participants either received 1000 mg l-carnitine or placebo, twice daily for two weeks. Participants in the groups were matched on the basis of VO2max, which was established using a 15 minute running test two weeks prior to the experiment. For the experiment itself, participants were asked to run 15 km at their maximum effort. Blood samples were collected immediately, 2, and 24 hours after exercise.
