Circadian rhythm of heart rate and heart rate variability in pregnancy [PDF]
npj Women's HealthThe autonomic nervous system (ANS) regulates physiological changes during pregnancy, supporting fetal development and homeostasis. Heart rate (HR) and heart rate variability (HRV) are well-established, non-invasive biomarkers of ANS function.

Bone mechanical loading reduces heart rate and increases heart rate variability in mice [PDF]
Bone ReportsCardiovascular disease and osteoporosis are clinically associated. Bone adapts to mechanical forces by altering its overall structure and mass. In response to mechanical strain bone cells release signaling molecules and activate the nervous system.
