Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The exercise program will match participants with Down syndrome (DS) with a student mentor from their community to exercise together, one­-on­-one at their local gym. The program will be a 12­ week program, with two, one hour sessions per week (24 sessions in total). The exercise program will comprise progressive resistance training (weight training). Programs will be prescribed by a physiotherapist from the research team, according to international best practice guidelines from the American College of Sports Medicine. Participants and mentors will document programs and notes in an exercise logbook. Mentors will be recruited from Allied Health students at La Trobe University Bundoora (any discipline and any year). All mentors are paid employees, based on residential location and will hold a current police check and working with children's check.

An Experimental group will complete the 12-­week exercise program twice a week and will log the exercises performed and the intensity at which they are performed (e.g. weight/ resistance used, number of repetitions). A control group will continue with their usual activities for 12 weeks and receive the exercise intervention after their second assessment.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomly assigned using sequentially numbered sealed opaque envelopes prepared by an independent researcher with no role in recruitment or assessment;

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomly assigned using a permuted block design created by a computer random number generator

Statistical methods / analysis
A sample size of 30 participants will be recruited for this phase I feasibility trial. A sample size of n=30 would be sufficient detect a large effect of 0.55 at power of 0.8 and alpha level of 0.05. However, for this type of intervention it is not expected likely that a large effect of 0.55 favouring the intervention group will be found. However, a sample size of n=30 will enable estimates of the standardised mean difference to inform design of a phase II trial.
Data will be analysed depending on allocation (intention to treat analysis) using Analysis of Covariance (ANCOVA) with baseline values as co­variate. If more than 5% of data is missing, a multiple imputation process will be used, leading to the assumption that data are missing at random is met.

Summary
Brief summary
We want to determine the effect of regular exercise on cognitive functioning in young adults with Down syndrome. We will compare the effect of a 12-­week exercise intervention on cognitive function against a wait list control group.
Participants will complete a weight training program with a mentor to assist them, at a local gym. Exercise sessions will run for one hour, twice a week for 12 weeks.
We will recruit a 30 participants aged 15-35 years old with Down syndrome. Baseline data on Executive functioning, Short ­term Memory, Information processing speed and Intellectual ability will be collected at baseline (week 0). Executive functioning, Short ­term Memory and Information processing speed will be measured again during follow­-up (week 13) after having either completed the exercise program or doing their usual activities. We will also collect data on participant demographics.
