Summary
Changes of selected indicators of lipid metabolism in the liver of the offspring of rat mothers exercised during pregnancy and of control mothers were followed up. Male offspring of exercised mothers were heavier at the age of 35 days and lighter at the age of 90, 100, and 108 days. The concentration of total lipids and fatty acids was raised in female offspring at the age of 35 and 90 days, and did not differ or was reverse (i.e., lower) in male offspring of exercised mothers compared to controls. The cholesterol concentration in the liver was increased in both female and male offspring of exercised mothers. The liposynthesis (studied in vivo after injection of Na-acetate-1-14C) tended to be lower in female offspring, and varied in male offspring of exercised mothers. In a subsequent in vitro study (incubation of liver slices with Na-acetate-1-14C) a lower total lipid and fatty acid concentration in the liver of male offspring of exercised mothers (108 days old) was found together with higher level of serum free fatty acids and unchanged liposynthesis. Finally, a higher concentration of cholesterol, higher synthesis of fatty acids and lower cholesterogenesis in small intestine in male offspring of exercised mothers 100 days old compared to those of control mothers was shown. As follows, daily work load during pregnancy results in significant changes of lipid metabolism in the liver and small intestine of the offspring.
