This dataset describes the results of the pilot study which was conducted between July and October 2022. This pilot study captured the views of participants on the study design protocol of the main study. This was made possible by recruiting 9-10-year-old children, their parents, and older adults (aged 54-57 years). We acquired the feedback from the participants on the main study design protocol using informal interviews. In addition, we assessed the potential exercise protocols, one on a treadmill and one on a bike, by asking children and older adults to undertake them and utilising their feedback.
