The exercise performed during pregnancy can be of great help to obese mothers according to a new study published in Physiological Reports and conducted by researchers at the University of Cambridge.
According to the researchers, in particular, physical activity would help mothers to restore key body tissues during pregnancy.
It is well known that physical exercises can help manage sugar levels in the blood and generally reduce health problems even in pregnant women, however the beneficial effects on tissues have never been well analyzed.
To overcome this shortcoming, researchers at the English University carried out experiments on mice: they fed various females with a diet rich in sugars and fats to make them obese.
They then subjected the rodents to various sessions of exercise on rolling carpets for 20 minutes a day for at least a week before conception and then for 12.5 minutes a day until the 17th day of pregnancy (the entire pregnancy of a mouse lasts about 20 days).
The researchers discovered beneficial effects concerning the metabolic health of obese mouse mothers, effects that were due to the changes with which the molecules and in general the cells communicated with maternal tissues during pregnancy.
In particular the key organs affected were the white adipose tissue, the skeletal muscles and the liver.
According to Amanda Sferruzzi-Perri, researcher at the Department of Physiology, Development and Neuroscience of the University of Cambridge, one of the authors of the study, “A moderate level of physical exercise immediately before and then during pregnancy leads to important changes in the different tissues of the mother obese, effectively making the tissues more similar to those seen in non-obese mothers “.
