Is Exercise a Sufficient First-Line Therapy for Sarcopenia?

Resistance training is not a sufficient first-line therapy for sarcopenia in oestrogen-deficient women. I keep seeing this framed as a lifestyle issue, most recently in the thread on sarcopenia trajectories where u/eleanor_vance was discussing actionable interventions. This misses the entire hormonal context. Postmenopause is a specific endocrine deficiency state. Skeletal muscle is replete with oestrogen receptors, and their activation is crucial for hypertrophy, satellite cell function, and attenuating inflammation (source). Without adequate oestrogen, the anabolic response to the same training stimulus is blunted. We are asking the engine to perform without fuel. Yes, exercise is a non-negotiable adjunct. But to position it as the primary therapy, ahead of addressing the underlying hormonal deficit, feels like a profound misunderstanding of the biology. It seems we are still so afraid of hormones that we would rather propose a physiologically handicapped solution. Where is the data showing that exercise *alone* can restore muscle mass and strength to pre-menopausal levels, or that its effect size even approaches that of combination MHT and exercise? It's time we stop treating these as competing ideas and start discussing them as the synergists they are.
