Previous research from the University of Connecticut has shown that supplementation with Carnipure, a very stable salt form of L-carnitine, beneficially affects markers of oxidative stress following resistance exercise. However, the mechanism for this response remained unclear.
In this recent Lonza-sponsored study, changes were found in tissue oxygenation response of the thigh muscle in resistance-trained athletes during the recovery periods following squat exercises. This led to the conclusion that the Carnipure-supplemented group had higher muscle oxygen consumption than the placebo group.
This research is supported by another study actually published at the same time by an Indian research group led by Arkadeb Dutta in Experimental Physiology. In this study, rats were exposed to hypoxia-induced oxidative stress and supplementation with L-carnitine was found to reduce oxidative damage and thereby delay muscular fatigue.
