Popis: The aim of this study was the effect of endurance exercise and probiotic supplement enriched with amino acid leucine and vitamin D on the gut-muscle axis in aged male rats. For this purpose, 25 male Wistar rats (5 rats in each group) in two age groups of 8 to 12 weeks (young) and 18 to 24 months (elderly) were randomly divided into 5 equal groups of old control (OC), young control (YC), endurance exercise (OE), supplement group (OS) and endurance exercise plus supplement (OES) were divided. The results showed that 8 weeks of endurance training (three times a week) and supplemental oral gavage (5 times a week) caused a significant change in postbiotics (decrease of indoxyl sulfate (IXS) and increase of Short-chain fatty acids (SCFAs)). The role of OS in reducing IXS was more prominent than OE and OES variables; of course, the synergistic effect of OES (P=0.000), caused a greater improvement in the amount of SCFA. Also, Administering the supplement alone and at rest (without exercise) could not cause a significant increase in VO2max (P=0.449). But, the effect of exercise on increasing VO2max index was more effective than OS and even OES. Eventually, the independent variables made a significant difference on the Villus height (VH) (except for the OS group) and number of goblet cells (GC) compared to the OC group (P
