According to an article published in the New York Times, “Does Exercising During Pregnancy Lead to Exercise-Loving Offspring?” scientists speculate whether a growing baby’s body and its DNA can be changed by the environment it experiences in the womb before and after birth. Researchers speculate that after a number of studies identified various snippets of DNA, a person carrying them predisposes that person to be active, while other gene variations may result in a person being inactive.
Researchers at Baylor College of Medicine andRiced University in Houston crossed two genetically identical females with two genetically identical males. Half of the mice had a running wheel and half did not during their pregnancy. The second generation mice were removed from the first and kept in a cage without a running wheel or visual ability from their mothers running on the wheel. The results were that the second generation mice from the active running mice during her pregnancy were also active. The second generation mice from the in-active mother was not as active as well.
From these results scientist concludes that there is a clear implication “that a mother’s activity during pregnancy likely affects the physical activity of her offspring.”
I found this article to be a bit random, because there are so many factors that prevents physical activity during a pregnancy. Also, during the first year of youth, a baby goes through many growth spurts and a significant change during the fourth and fifth year. How can a child’s future activeness or inactiveness be dependent on a mother’s pregnancy process? Although, these are studies based on mice experiments and scientist hope to find a link between mother’s activeness during pregnancy to her offspring’s future in humans; I don't feel that a mothers physical activeness dictates her child's future activeness.
