Influences of taste preference learning on swimming exercise ratsπ branchedchain amino acid and neurotransmitters |

| Abstract: | The purpose of this paper was to investigate the relationship of swimming ratπ s BCAA ,GABA , Trp concent ration and metabolism in blood and CSF af ter amino acids preference learning so that a new method to delay or eliminate exercise fatigue could be found. Changes of BCAA and neurot ransmit ters were observed in blood and CSF af ter CTP and 7d swimming t raining by using HPLC method. It was shown that in blood ,BCAA concent ration in exhaustive swimming group was higher than that of the cont rol group ( P < 0. 05) . In CSF ,amino acid preference and suitable swimming af ter amino acid preference group was lower than that of the cont rol group ( P < 0. 01 or P < 0. 05) . Bloodπ s 5 - HTP concent ration in amino acid preference and suitable swimming af ter amino acid preference group increased significantly ( P < 0. 05) . However ,CSFπ s 5 HTP and Trp decreased ( P < 0. 01) . CSFπ s GABA decreased in all groups except the swimming group af ter amino acid preference group ( P < 0. 05 or P < 0. 05) . The blood GABA remained relatively stable. It was concluded that amino acid preference learning and suitable swimming could modu2 late BCAA ,GABA ,Trp and 5 HTPπ s concent rations in blood and CSF. They had the same effect s in the body stimulation. However , there were lit tle effect s in promoting each other . Preference learning could weaken exhaustive swimming exercise induced stimulation on the body ,which was significant for maintain2 ing homeostasis in the body and delaying fatigue. |
