Studies related to Rating of perceived exertion (RPE) and L-Carnitine

Chronic Oral Ingestion Of L-carnitine And Carbohydrate Increases Muscle Carnitine Content And Alters Muscle Fuel Metabolism During Exercise In Humans

Over 24 weeks, healthy male subjects (nonvegetarian) consumed 80g of carbohydrates with or without 2g L-carnitine-L-Tartrate. The carnitine group had 21% higher carnitine levels, showed a greater percentage of fat burning at 50% intensity exercise, and had a better energy production (80% intensity) and performance relative to control (+11%) and thought to be secondary to bioenergetic changes.
