A recent study investigated the fetal responses to acute high-intensity exercise during pregnancy among healthy pregnant athletes. The study observed that high-intensity interval training wasn't associated with lasting harm to fetal well-being, as the cases of prolonged fetal bradycardia that occurred during exercise sessions resolved within 8 minutes post-exercise without lasting effects. The study provides valuable data for informing evidence-based exercise guidelines for pregnant athletes.
