L-carnitine is a natural amino acid derivative that is important in energy and fat metabolism
On three visits (before, 3 months in, and after 6 months of supplementation), subjects exercised for 30 min on a low intensity (50% Wmax), 30 min on a higher intensity (80% Wmax), and finally performed a 30 min all-out time trial test
Therefore, a coupled assay containing carnitine monooxygenase, MSA-DH and 5 M MDH in the presence of the respective cofactors NADH (10 mM) and NAD + (10 mM) was performed (Figure 4A)
