Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will complete an Expression of Interest Form. Potential participants will then be contacted by researchers who will apply the inclusion and exclusion criteria, explain the study and ask for verbal consent. Once written consent is obtained participants will enter the study and will be allocated to the 'exercise' group or the 'control' group. Allocation will be concealed using numbered sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation sequence will be generated using a web-based randomisation program (http://www.randomization.com)

Summary
Brief summary
Barrett’s oesophagus (BE) involves changes in the lining of the oesophagus and is a precursor for a type of oesophageal cancer. Obesity is a cause of BE and research suggests that certain hormones produced by fat tissue may be the mechanism through which obesity leads to cancer of the oesophagus.

Exercise training may be an effective intervention in reducing oesophageal cancer risk given the strong links between BE, obesity and metabolic disturbances.

There is some trial evidence that moderate-intensity exercise can improve obesity related hormone levels in overweight people without BE, but to date, no such evidence exists for patients with BE.

By randomising patients with BE to either an exercise regimen or a stretching regimen, we aim to determine whether 24 weeks of moderate-intensity exercise will lead to changes in levels of certain hormones associated with oesophageal cancer development.
