Clinical Scorecard: The Impact of Sex Hormones on Physical Performance in Midlife Women: Insights from the Menarche-to-PreMenopause Research
At a Glance
Category
Detail
Condition
Decline in physical performance related to sex hormone changes in midlife women
Key Mechanisms
Sex steroids (estrogens and androgens) regulate muscle function via receptors affecting protein synthesis, mitochondrial function, and metabolism; hormonal declines during menopause impact muscle strength and balance
Target Population
Middle-aged women in their 40s undergoing menopausal transition
Care Setting
Clinical research and assessment in outpatient or community health settings
Key Highlights
Estrone (E1) concentrations negatively associated with chair rise performance in women aged ~44.6 years
Higher dihydrotestosterone (DHT) and sex hormone–binding globulin (SHBG) concentrations positively associated with better standing balance
No significant associations found between other sex steroids and handgrip strength after full adjustment
Guideline-Based Recommendations
Diagnosis
Assess sex steroid hormone levels (estrone, estradiol, testosterone, DHT, DHEA, SHBG) using sensitive assays such as liquid chromatography–mass spectrometry and immunoassays
Evaluate physical performance using standardized tests: handgrip strength, chair rise, and standing balance
Management
Consider hormonal status when addressing declines in muscle function during midlife in women
Monitor and support muscle strength and balance especially during perimenopause to mitigate fall risk
Monitoring & Follow-up
Regularly assess physical function performance tests to detect early declines
Monitor changes in sex hormone levels as part of midlife health evaluations
Risks
Sharp decline in estrogen during menopause may exacerbate muscle strength loss and increase fall risk
Lower androgen levels may contribute to reduced muscle protein synthesis and function
Patient & Prescribing Data
Middle-aged Australian women aged approximately 44–46 years in premenopausal or early menopausal transition
Sex steroid concentrations correlate variably with physical performance; estrone negatively impacts chair rise ability, while DHT and SHBG support standing balance, suggesting hormone-related targets for maintaining muscle function
Clinical Best Practices
Incorporate assessment of sex hormone levels when evaluating midlife women with declining physical performance
Use performance-based tests (chair rise, standing balance, handgrip strength) to monitor functional status
Recognize the multifactorial nature of muscle function decline including age, body size, and hormonal changes
Focus interventions on maintaining muscle strength and balance during perimenopause to reduce frailty risk
Women reported improvement across 6 cognitive domains during 12 months of estriol-based treatment, while murine models suggested a potential astrocyte-mediated mechanism.
So get this: sodium may track with memory decline (in men), steroids might not be “immunosuppressive” in the ICU, and second pregnancies reshape the brain differently than first. Same theme: biology is less binary than we teach it.
