The American College of Obstetricians and Gynecologists (ACOG) recommended in 1985, that pregnant women should not exceed an exercise heart rate (HR) of 150 beats/min due to the potential dangers of fetal malformation, intrauterine growth retardation, and fetal distress.1 However, few investigations have measured fetal and maternal outcomes in female athletes who are well-conditioned before conception and continue to train during pregnancy.
