The CHAIN Study looks to investigate the chronic effect of physical activity and inactivity.
Life expectancy has been increasing for the last 150 years, but the maintenance of health has not kept pace with increased lifespan and, on average, UK adults spend the last decade of life in poor-health, which can have a major impact on the individual and society. Persistent physical inactivity is thought to be a key factor contributing to the risk of poor health and physical decline occurring in middle-aged and older adults. However, the biological mechanisms causing the health issues which develop with long term sedentariness are poorly understood.
This study aims to understand the effects of physical activity and inactivity on body functioning across a six-month period. Before and at several points during the intervention period, participants will be asked to make some measurements at home and attend the University of Nottingham to have multiple assessments made. These include fitness, muscle strength and function tests, computer-based brain puzzles, and having muscle and fat tissue biopsies, bloods taken and MRI scans.

Frequently Asked Questions
How long are you recruiting participants for the CHAIN studies?
Participant recruitment for the CHAIN studies will end in May 2027.
Can I participate in the study if I am going on holiday during the study period?
Going on holiday whilst participating in the study does not necessarily exclude you from taking part. This will be assessed on a case-by-case basis and will require a discussion with the invesitgators.
