| Values | Supplementation of L-carnitine led to reduced respiratory quotient during aerobic-anaerobic threshold exercise compared to placebo |

In this crossover study, participants supplemented either 1.036g L-Carnitine or placebo three times daily for seven weeks leading up the testing period. Then, after a week long washout period, they took the other treatment. The test consisted of strenuous and anerobic/anaerobic threshold treadmill exercise in normoxic (20.9% oxygen) followed by hypoxic (13.0% oxygen) conditions.
