Description
Kidney weight, body weight, body specific gravity, and body length were examined in five-week-old offspring of Wistar-Kyoto (WKY) dams that exercised during gestation. Nineteen female WKY's were randomly assigned to 1 of 2 groups: exercise (E), and sedentary (S). Kidney weight (KW), body weight (BW), body specific gravity (SO), and body length (BL) were measured at 5 weeks of age. SO was measured by hydrostatic weighing. A one-way ANOVA with Bonferroni indicated post hoc analyses the female E offspring had significantly lower SO (p<0.05) than female S offspring. The male E offspring had significantly larger BL (p<0.05) than male S offspring. There were not significant differences in BW or KW. These results demonstrate moderate gestational exercise may generate a long-term positive benefit in progeny of exercised WKY dams with respect to body density, and gestational exercise may generate increased body lengths in the progeny.
