Advances in our understanding of the biology of skeletal muscle ageing are being made at pace, with great potential for these findings to inform the identification of novel treatments for sarcopenia. However, translation of findings from animal models to humans has been hampered by limitations of existing human muscle biopsy studies. Devised to directly address this challenge, the Muscle Ageing and Sarcopenia Study (MASS) Lifecourse is a unique resource for the study of human muscle ageing across adulthood. This deep-phenotyped observational study of 260 community-dwelling men and women aged 18 to 85 years living in North East England includes muscle biopsy samples and detailed characterisation of physical function, health status and sociodemographic and behavioural risk factors. Underpinned by broad interdisciplinary research and clinical expertise this study is catalysing cutting-edge translational research on human muscle ageing across the adult life course.
