dc.description.abstract This study examined the effects of 14 days of L-carnitine supplementation on blood and muscle lactate concentrations, and carnitine fractions, during high intensity sprint cycling exercise. Eight subjects performed three experimental trials - control I (CON I, 0 days), control II (CON II, 14 days), and L-carnitine (LCN, 28 days). Each trial consisted of a 4 min ride at 90% VO2max, followed by a rest period of 20 min, and then 5 x 1 min rides at 115% VO2max (2 min restbetween each). Following CON II, all subjects began dietary supplementation of L-carnitine for a period of 14 days (4 g/day). L-carnitine supplementation had no significant effect on either muscle carnitine or lactate concentrations following the 4 min 90% ride. Plasma total acid soluable and free carnitine concentrations were significantly higher at all time points following supplementation. Differences observed in blood hydrogen ion and lactate concentrations between CON I and CON II appear to be the result of an order effect. The data from the present investigation indicate that L-carnitine supplementation has no significant effect on blood or muscle lactate accumulation following high intensity sprint cycling exercise.
