Daily movement behaviours can be broadly classified into four categories, dependent largely on intensity, namely sleep, sedentary behaviour, light physical activity and moderate-to-vigorous physical activity. The government recommend children and young people partake in an average of 60 minutes of moderate to vigorous physical activity every day, in order to maintain good health. Whilst current research supports the need to improve physical activity engagement in childhood, interventions thus far have shown little to no significant improvement. Furthermore, whilst it is suggested that children with asthma follow the same guidelines in regard to engagement in physical activities, but no guidance is given as to the type of exercise, or whether different intensities are more suitable for different clinical groups.

The aim of this project is to characterise the composition, and level of, physical activity behaviours throughout the day, with specific interest in exploring whether those diagnosed with asthma show similar patterns to those without asthma. The data set will be combined with data from the Millennium Cohort Study and the Commando Joes/X4A Trial, and analysis will consider age, sex and asthma status.
