One study found that exercise during pregnancy can protect children from obesity later in life.
Previous studies have already shown that exercise of obese women during pregnancy was beneficial for their offspring.
But a new study showed for the first time that it was the same when non-obese women are active during pregnancy.
We will tell you what is true. You can form your own view.

Jun Seok Son, a doctoral student at Washington State University, who conducted the study, said, "Based on our findings, we recommend to women – that they be obese or not with diabetes – to exercise regularly during pregnancy, as this benefits their children. metabolic health.
"Our data suggest that lack of exercise in healthy women during pregnancy can predispose their children to obesity and badociated metabolic diseases, including altering thermogenic function."
The researchers examined the offspring of mice who engaged in moderate-intensity physical activity for 60 minutes each morning of pregnancy.
Offspring born from mice that did not exercise were used as a control group.
At weaning, the offspring of the exercising mice had an increase in brown adipose tissue protein levels relative to the control group.
This type of fabric converts fat and sugar into heat.
The researchers also observed higher body temperatures in the exercise group, indicating that their brown adipose tissue was more effective – or had superior thermogenic function – which was proven that it could prevent cancer. Obesity and metabolic problems.

After weaning, the offspring followed a high-fat diet for eight weeks.
The mice in the exercise group not only gained less weight with the high-fat diet, but also exhibited fewer symptoms of metabolic diseases such as diabetes and fatty liver.
The researchers plan to conduct additional studies to better understand the biological mechanisms responsible for improving metabolic health in the children of mothers who have exercised.
Mr. Son was scheduled to present the research at the 2019 Experimental Biology Meeting in Orlando, Florida on Sunday.
