May warrant caution with maternal exercise or hyperthermia in small fetuses; leaves open need for prospective outcome trials.
How do maternal exercise, increased temperature, and circadian variation affect fetal heart rate in normal versus small for dates fetuses?
Maternal exercise and increased core temperature elicit normal heart rate increases in healthy fetuses but can cause concerning heart rate decelerations in small-for-dates fetuses.
Tuffnell et al. (1990) studied this question.
