5. (2 pts) Based on the introduction section of the article, what was the research question that prompted this study? It may not be explicitly stated, and there may be more than one; you will have to read the introduction and interpret what question is driving the study. The question that prompted this study came from several studies. There have been several studies with positive results of I.V. infusion of carnitine and the delay of depletion in muscle glycogen but none from ingesting carnitine. Through ingestion of carnitine, if there was an increase of carnitine in the muscle, it will increase muscle fat oxidation which would then lead to a delay of depletion in muscle glycogen.
6. (2 pts) What did the authors hypothesize? The authors hypothesized four things. First, the authors wanted to see if constant feeding of L-carnitine and carbohydrates to the participants would increase the muscle TC content just as they observed from I.V. infusion of the L-carnitine.…
