Physical Activity

As part of the INTERVAL study, we will be asking just over 7,000 randomly-selected study participants to wear a physical activity monitoring device for 7 days. The information we gather from these measurements will be added to other data we are collecting to provide evidence on the optimum donation intervals for donor well-being and blood supply.

If you are currently a participant on the Physical Activity Study, please see the relevant FAQs section to find out more about your participation in the study.
