Maternal and fetal cardiovascular response to moderate-to-vigorous intensity exercise in singleton and twin pregnancies

The authors aimed to investigate the maternal and fetal cardiovascular responses to moderate-to-vigorous exercise in singleton versus twin pregnancies, addressing the lack of empirical evidence behind current exercise guidelines for pregnant individuals carrying twins. They found that while resting heart rate and mean arterial pressure were higher in women with twin pregnancies, the cardiovascular responses to submaximal exercise were similar between both groups, and exercise did not adversely affect fetal well-being.
