Studies concerning some acute biological changes after endovenous administration of 1 g l-carnitine, in elite athletes.

Author information

Sports Polyclinic, Bucharest, Romania.


Acute effects of l-carnitine (vials of 1 g endovenous) were recorded in a group of elite athletes (17 swimmers) by a prospective double-blind placebo-controlled trial and cross over. Significant changes were registered after l-carnitine injection, compared to placebo, for FFA, triglycerides, lactic acid after exercise, evoked muscular potential, 90 to 120 minutes after injection. The authors explain these changes by the increase of free carnitine, which permits a larger quantity of FFA to enter the mitochondria and to be more extensively used as energy source.
