Abstract: The antifatigue effects of L-carnitine from mutton were determined by parallel and crossover experiments respectively. The effects on swimming time,body index,physiological and biochemistrical indices in serum,contents of L-carnitine and fragments of fatty acid in leg muscle was observed. The results showed that L-carnitine can prolong the average swimming time,decrease the body weight and abdomen fat weight,and decrease the contents of CHO,TC,urea nitrogen and lactic acid in serum. The content of L-carnitine is significantly related to the swimming time by results of HPLC. L-carnitine hsa significant antifatigue effect and can supply energy by participate in fatty acid metabolism.

Key words: L-carnitine, HPLC, GC-MS, fatty acid, antifatigue
