Popis: Abstract Background Amongst healthy older people, a number of correlates of impaired skeletal muscle mass and function have been defined. Although the prevalence of obesity is increasing markedly in this age group, information is sparse about the particular impacts of obesity on ageing skeletal muscle or the molecular mechanisms that underlie this and associated disease risk. Methods Here, we examined genome‐wide transcriptional changes using RNA sequencing in muscle biopsies from 40 older community‐dwelling men from the Hertfordshire Sarcopenia Study with regard to obesity (body mass index [BMI] >30 kg/m2, n = 7), overweight (BMI 25–30, n = 19), normal weight (BMI
