HER-MUSCLE aims to unravel the mechanisms by which oestrogen enhances muscle growth, providing insights for targeted therapies to improve the health and physical function of postmenopausal females.\n\nFocusing on postmenopausal females, an increasingly at-risk demographic, HER-MUSCLE addresses a critical gap in understanding how oestrogen influences muscle mass and function during anabolic (exercise) conditions.\n\nThe project involves:\n\n1. Clinical Trial: Postmenopausal females will receive either oestrogen or placebo, twelve weeks of exercise training to detect oestrogen regulatory role on muscle mass and function.\n2. Molecular Analysis: Advanced techniques will study the muscle microenvironment, focusing on muscle stem cells (MuSCs), fibro-adipogenic progenitors (FAPs), and other cells critical for muscle regeneration and maintenance.\n3. Mitochondrial Function assessed in vivo via magnetic resonance spectroscopy: The impact of oestrogen on mitochondrial health will be examined, exploring how it preserves mitochondrial function and ability to recovery and resist fatigue in response to muscle contractions.\n\nOur preliminary data indicate that oestrogen can promote muscle protein synthesis. HER-MUSCLE aims to pave the way for novel therapeutic strategies to manage sarcopenia in postmenopausal women, ultimately leading to better health outcomes and enhanced well-being for this growing population segment.",[88,89],"Menopause Related Conditions","Exercise Training",[29,91,92,93,9,94,95,96,97],"Strength training","Cardiovascular training","Muscle hypertrophy","Mitochondria function","Muscle strength","Menopause","Muscle mass","2026-05-23",{"date":100,"type":101},"2026-06-01","ACTUAL",{"date":103,"type":101},"2026-02-01",{"date":105,"type":82},"2027-08-01",{"name":61,"class":6},1]
