Interval Training and Cardiometabolic Health in Reproductive-Aged Females

This review examines the benefits of interval training, particularly high-intensity interval training (HIIT), for improving cardiometabolic health in reproductive-aged females, especially those with polycystic ovary syndrome (PCOS). HIIT is more effective than moderate-intensity exercise in enhancing cardiorespiratory fitness, reducing fat mass, and improving insulin sensitivity. It may also improve metabolic, hormonal, and cardiovascular indices, potentially aiding fertility and overall health. However, factors like oral contraceptive use can affect its effectiveness, and more research is needed to establish comprehensive exercise guidelines for this demographic. While HIIT appears safe during pregnancy and may benefit women with obesity, PCOS, diabetes, and gestational diabetes, further studies are necessary to confirm its safety and efficacy during pregnancy and postpartum.
