Chenopodium ambrosioides associated with whole body vibration exercises alters the feed intake in Wistar rats

The consequences of treatment involving the use of a natural product and whole body vibration (WBV) exercise have been investigated. The aim of the present study was to evaluate the effects of the joint treatment with an aqueous extract of Chenopodium ambrosioides and WBV on physiological parameters in rats. Wistar rats (n=20) were divided equally into four groups: control group (CG), treated with C. ambrosioides (CHE) group, exposed to 50 Hz of mechanial vibration (VBR), and treated with C. ambrosioides and exposed to 50 Hz of mechanical vibration (VBR + CHE) daily for 6 weeks. The body mass of the animals was determined weekly, the feed intake and the stool consistency were measured daily. One day after the 6 weeks of treatment, samples of blood were collected and used for biochemical analysis. Along 6 weeks, there was an increase (P<0.001) in the feed intake in VBR group and a decrease in the CHE group in comparison with other groups. The levels of the enzyme aspartate aminotransferase (AST) in VBR + CHE group decreased (P<0.05) in comparison with other groups. No differences were found in body mass and stool consistency. WBV altered the feed intake without directly affecting the body mass. Moreover, WBV in association with C. ambrosioides caused alteration in the enzymatic activity of AST.
