Aging of the musculoskeletal system: How the loss of estrogen impacts muscle strength

Abstract

Skeletal muscle weakness occurs with aging and in females this is compounded by the loss of estrogen with ovarian failure. Estrogen deficiency mediates decrements in muscle strength from both inadequate preservation of skeletal muscle mass and decrements in the quality of the remaining skeletal muscle. Processes and components of skeletal muscle that are affected by estrogens are beginning to be identified. This review focuses on mechanisms that contribute to the loss of muscle force generation when estrogen is low in females, and conversely the maintenance of strength by estrogen. Evidence is accumulating that estrogen deficiency induces apoptosis in skeletal muscle contributing to loss of mass and thus strength. Estrogen sensitive processes that affect quality, i.e., force generating capacity of muscle, include myosin phosphorylation and satellite cell function. Further detailing these mechanisms and identifying additional mechanisms that underlie estrogenic effects on skeletal muscle is important foundation for the design of therapeutic strategies to minimize skeletal muscle pathologies, such as sarcopenia and dynapenia.

  • Data examining nucleolar adaptation in female cohorts, particularly considering ovarian hormone fluctuations, remain scarce.

    “Data specifically examining nucleolar adaptation in female cohorts, particularly considering the potential modulatory effects of fluctuations in ovarian hormones on mechanotransduction, remain scarce [213,214,215].”

    From Ribosome Biogenesis as a Putative Bottleneck to Skeletal Muscle Hypertrophy: Mechanisms, Human Evidence, and Practical Modulators (2026) · cites this paper as [215]

    The Introduction says aged female rodents are infrequently used to study how estrogen loss affects muscle strength. The muscle protein turnover section discusses menstrual-cycle hormone fluctuations, but neither passage addresses nucleolar adaptation or whether data on hormone-modulated mechanotransduction in female cohorts are scarce. Searches for nucleolar adaptation, ribosome biogenesis, and mechanical loading found no passage establishing that claim. (LLM, conf=0.74)

  • Sarcopenia is a critical determinant of frailty leading to loss of autonomy and functionality in daily activities, and it increases hospitalization, osteoarthritis, osteoporosis, and risk of institutionalization.

    “Furthermore, it is a critical determinant of frailty that leads to loss of autonomy and functionality in daily activities. Besides, sarcopenia increases hospitalization, osteoarthritis, osteoporosis, and the risk of institutionalization [30].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
