Abstract
Purpose. The purpose of this study was to examine the effects of chronic L-carnitine and carbohydrate supplementation on body composition, perceived exertion, and athletic performance in recreationally-trained female endurance runners. Methods. On three separate occasions, twenty-one days a part, seven recreationally-trained female endurance runners performed a timed progressive treadmill test to exhaustion as well as a body composition assessment using the Bod PodÒ. Participants were randomly assigned to one of two groups – L-carnitine (LC) or L-carnitine plus carbohydrates (LC + CHO). The LC group consumed 2 g of L-carnitine L-tartrate and the LC + CHO group consumed 2 g of L-carnitine L-tartrate with 10 g of flavorless dextrose powder. Rating of perceived exertion, time to fatigue, and body composition was recorded during each of the three visits. Results. The results of this study revealed no significant interactions or main effects for time and treatment (p = .11). In addition, no significant differences were seen between subjects for body composition (%FFM p = .54; FFM p = .17; FM p = .75; %FM p = .57) or RPE (p = .95). Conclusion. In conclusion, this study demonstrated that chronic carnitine and carbohydrate feeding likely does not influence RPE, time to fatigue, or body composition in recreational endurance-trained female runners.
