摘要:The effect of exercise on vitamin B6 metabolism and PLP-dependent enzymes was studied in rats fed a diet with or without vitamin B6. Metabolism of some amino acids (citrulline, arginine, ornithine and threonine) inhibited in the B6-deficient rats was normal-ized during exercise. Exercise was also effective in storing vitamin B6 in the body by lowering excretion of vitamin B6, when intake of vitamin B6 was restricted. Aspartatae aminotrans-ferase activity was higher in the red portion of the gastrocnemius muscle than that of the white one, whereas glycogen phosphorylase activity was vice versa and furthermore glyco-gen content in the white portion was very low in the vitamin B6-deficient rat. From the data obtained, it has been suggested that the red and white portions of the gastrocnemius muscle seemed to be more important in metabolizing amino acids and hydrolyze glycogen, respec-tively.
