The aim of this study was to examine the effect of acute administration of L-Carnitine on blood energy metabolism, blood gases and performance. Thus, The comparative analysis on the effect of lactate, RER, NH_3, pH, pO_2, pCO_2, peakVO_2 and all out time during maximal graded exercise through the acute administration of L-Carnitine 3g(β-hydroxy-γ-[trimethylammonia]-butyrate; Vitamin BT. SIGMA, USA) was conducted to 5 male wrestlers. The obtained results are as follows: 1. In the reaction of blood energy metabolism, the reaction of lactate, RER, NH3 were no significant differences between L-Carnitine group and placebo group. But, There was significant change in two groups according to duration. 2. In the reaction of blood gases, the reaction of blood pH, pO_2, pCO_2 value were no significant differences between L-Carnitine group and placebo group. But, There was significant change in two groups according to duration. The value of pH and pCO_2 was significantly decreased after maximal exercise compared to before exercise and rapidly increased in the recovery phase. But, pO_2 was significantly increased after maximal exercise compared to before exercise and rapidly decreased in the recovery phase. 3. In performance indices, the reaction of maximal oxygen uptake(peakVO_2) and All out time were no significant differences between L-Carnitine group and placebo group. In conclusion, these results indicate that L-Carnitine acute administration does not provide an ergogenic effects related to fatty acid oxidation during graded maximal exercise.
