Does exercise during pregnancy help the baby? Babies of moms who exercise may have stronger and healthier hearts, according to recent research. Scientists found that women who were active while pregnant had babies with lower heart rates, both in utero and after birth, suggesting that a mom’s fitness was making her baby’s heart more fit, too.
What are the effects of exercise in pregnancy on the developing fetus? Maternal exercise also showed beneficial effects for the fetus. Low-intensity exercise in early pregnancy increases the umbilical blood flow and can improve placental circulation as well as the fetal cardiac adaptation to the environment.
