A new study has confirmed that babies born to healthy mothers who exercise during pregnancy carry a normalize weight in comparison to the mothers who do not opt for exercise.

Dr. Paul L. Hofman of the University of Auckland and his colleagues write, "The modest reduction in birth weight in this study may lead to a long-term reduction in the risk for obesity in offspring of women who exercised in pregnancy".

The research team chose 84 pregnant women and assigned them with at least five 40 minute session at home for a period of a week on an exercise bike, in order to do a comparison with a non - exercise group. The research was carried out at the starting of 20 weeks through delivery.

It was found after the study that the set of women who were subjected to exercise were fitter than the women who did not exercise and there was no noticeable difference between the mass indexes.

The babies who were born to the exercising mothers were approximately 140 grams lighter in weight than the control groups, though the average length was similar.

The researchers have concluded that sufficient amount of exercise during pregnancy is useful in maintaining the women's responsiveness towards insulin.
