Primary sarcopenia is a geriatric syndrome characterised by age-related decline in muscle strength, mass, and quality. Our analysis of >430,000 UK Biobank participants between 40 and 82 years of age revealed a clear sexual dimorphism in arm muscle ageing. While age-related strength decline was broadly comparable between sexes, muscle mass loss was considerably more pronounced in males. As a result, age-related muscle quality decline was found to be substantially greater in females. These general trends held cross-sectionally and longitudinally, and persisted after accounting for systematic size differences between sexes. These findings have important implications for the diagnosis and management of primary sarcopenia, a syndrome associated with reduced quality of life and significant social burden.
