| Abstract |
The aim of this study was to investigate the effect of carnitine supplementation on blood lipid profiles and respiratory exchange ratio. Each subject performed maximal exercise testing on a treadmill and the exercise intensity was determined based on the testing. All subjects were orally ingested both placebo and carnitine (3.3 g) at an interval of 1 week. Carnitine treatment group showed a significant change in serum FFA and lipase compared to pre carnitine treatment group. However, other variables showed no differences. Also, the RER was reduced by an average 0.02 and it was notably reduced by 0.05 at 10 min after exercise. These results indicate that acute supplementation of L-carnitine had the effect on an increase of FFA and activation of lipase. But the supplementation of L-carnitine had no effect on the other lipid metabolic indices in the serum and glycogen sparing effect. |
