Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants in the intervention group will complete an 8-week, mentored physical activity program called Walkabout. They will undertake to complete 150 minutes of moderate intensity physical activity per week during the program. The first 2 weeks will be a familiarisation phase, to introduce the program to the participants and allow them to adapt to the program with the aim of building up to 150 minutes of moderate activity by week 3.

Each participant will be teamed with a student mentor who will be a physiotherapy student. The participant and their mentor will complete two walking sessions together each week (each session will be 45 minutes in duration). The other 60 minutes of activity will be individually tailored to the circumstances of the participant. A planning session on how to implement these additional 60 minutes of walking without the mentor will be conducted at the start of the intervention period with a member of the research team, and a second planning session will be undertaken after 4 weeks to review progress and to make changes if necessary. All participants will receive motivational prompts (postcard reminders). The participants will wear a pedometer while they are walking to measure the number of steps completed in each session. They will also be encouraged to walk briskly. Information about the activity they do will be noted in a log-book.

Lifestyle
Comparator / control treatment
Participants in the control group will complete an 8-week program of social activities with a student mentor. The program will comprise social and recreational activities that would not be expected to have a fitness or training effect, such as painting, printing, music or social activities that do not incorporate a physical activity component. Each session of the social program will run for 90 minutes, equal to the time spent in the 2 mentored walking sessions each week in the intervention group. The control group participants will also receive the same level of feedback as the intervention group; they will receive postcards with simple messages similar to the motivational prompts received by the intervention group. These messages will provide information that is not intended to be motivational to increase physical activity, such as weather reports, details of a topical news story or sports results.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be recruited to the study and undergo baseline testing before being randomly allocated to either the social or intervention group. using a concealed allocation, block randomisation method. Participants will be considered in blocks. The order of the blocks will be generated using the website randomization.org and assignments sealed in sequentially numbered opaque envelopes. Using 'randomization.org', a list of numbers from 1 to 20 will be randomly generated in 2 columns . These two columns will then represent the 'intervention' group (1st column) and 'control' group (2nd column). The relevant group name will then written on a piece of cardboard and placed in an opaque envelope with the number of the participant on the front. A researcher not involved in recruitment will allocate the participants by opening the next envelope in the sequence.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The website randomization.org will be used.

Summary
Brief summary
This randomised controlled trial will compare the effect of an 8-week mentored physical activity program called Walkabout compared with a social program for young adults with Down syndrome aged 18-35 years. Specifically, it will examine if Walkabout increases their level of physical activity.
