Overview

Cross-sectional study explores gut microbiota impact on physical activity and function in older adults, suggesting implications for healthy ageing.

Key Points

  • This research aims to investigate the relationships between gut microbiota and movement behaviours in community-dwelling older adults.
  • Cross-sectional study involving 101 older adults aged 65-85
  • Participants wore accelerometers for 7 days to assess physical activity levels
  • Anthropometric measures and functional tests were conducted
  • Faecal samples were collected and analysed using 16s rRNA sequencing
  • Results were adjusted for diet, age, and activity levels
  • Prevotella copri was positively associated with moderate-to-vigorous physical activity and physical function
  • Negative associations were found between sedentary behaviour and gut microbiota composition
  • Roseburia species correlated with better mobility and strength measures
  • Pathogenic taxa like Bilophila wadsworthia were negatively linked to physical activity and handgrip strength
