12 weeks of intense interval training significantly reduces the Visceral Adiposity Index (VAI) in women with Polycystic Ovary Syndrome (PCOS), but does not significantly alter serum adipose levels.

If you have PCOS, 12 weeks of high-intensity interval training (3x/week) can improve your visceral fat profile (VAI) without necessarily changing your serum adipose protein levels. Focus on the VAI improvement as a key health benefit, even if other blood markers remain stable.

ModerateQualifiesMEDIUM confidence
The results revealed no significant difference in adipose levels after 12 weeks of intense interval training in the study group (P < 0.05). But a significant difference was observed in visceral adiposity index before and after the intervention in the study group (P < 0.05).
