Sarcopenia is the loss of muscle mass and strength associated with physical disability during ageing. Here, the authors analyse muscle biopsies from 119 patients with sarcopenia and age-matched controls of different ethnic groups and find transcriptional signatures indicating mitochondrial dysfunction, associated with reduced mitochondria numbers and lower NAD+ levels in older individuals with sarcopenia.
