Science | Inheriting Mom's exercise regime
Mounting evidence suggests that parents pass on more than just their DNA to their offspring. In the latest example, Eclarinal et al. examined the effect of exercise during pregnancy on the voluntary physical activity of the offspring in adulthood. The researchers kept pregnant mice in cages with either an unlocked or locked running wheel and monitored their physical activity. Daughters of moms who could exercise showed increased activity and voluntary exercise some 60 to 300 days after they were born. The findings complement others showing that in mice, the maternal environment can influence the metabolic status of progeny, and in humans, maternal exercise benefits offspring.
