In a rat model of menopause (ovariectomy), 8 weeks of treadmill exercise restored the expression of key brain angiogenesis-related factors that were reduced by estrogen deficiency. This suggests exercise may help counter vascular dysfunction in the brain associated with menopause.
This preclinical study investigated the effect of aerobic exercise on brain angiogenesis in an ovariectomized (OVX) rat model of menopause. Eighteen rats were divided into normal control, OVX control, and OVX with exercise groups. After 8 weeks, the study found that ovariectomy significantly decreased the expression of multiple angiogenesis-related factors (PDGF subunits, VEGF, Ang1, Ang2) in the cortex. The central result was that the exercise intervention significantly restored the expression of these factors in the OVX-exercise group. The authors speculate that exercise-induced hypoxia may upregulate these factors. The findings imply that exercise may help mitigate vascular dysfunction in the brain linked to estrogen deficiency, though direct translation to humans requires further study.
