Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The taiji sessions will take place for the first six weeks and during these six weeks there will be five taiji
sessions per week (one hour each) available for participants to attend. It is required that participants must
complete at least five hours of taiji training a week (minimum 1800 minutes during the initial six weeks) and at least two of these must be in the contact sessions. The contact session will be conducted as a group with a trainer and non contact practice will self practice and monitored by a log book. There is no limit on how many contact taiji sessions any individual attends, but the minimum of two contact sessions must be completed per week. Remaining hours of taiji training (non contact) must be recorded in log book with reflections on each non contact practice to ensure sufficient hours are completed.
After the initial six weeks there will only be one contact session a week for the remaining six weeks to revise any forgotten movements and check completion of log books. The emphasis on home taiji practice (non contact) will be strongly reinforced and the minimum of five hours of taiji training a week still applies. Participants will be asked to follow the DVD they were given at the commencement of the trail in regards to the training.

Comparator / control treatment
This is a three arm study and the three groups are A: Tai Chi (intervention) B: Gym (active control) and C:Wait list (non active control).
The gym group (B) will be the active control group and they will be provided with gym membership for the
duration of the trial (twelve weeks). As with the intervention group they will be given a journal to log
the amount of time and frequency of their exercise. It is also expected that they complete a total of
five hours of exercise per week including at least two hours at the UTS Fitness Centre. The participants will be assessed by the staff at the UTS Fitness centre and will be required to attend at least one of the scheduled exercise classes inclusive in the two hours they spend at the UTS Fitness Centre. There will be a weekly meeting with this group to check progress of journals.

The waiting list (C) will form the non active control and will be idle for the twelve weeks of the trial; however they will be given six weeks of taiji practice and the DVD after the twelve weeks as appreciation for their involvement in this trial.

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)
Once screened and consent form signed, partipants will be allocated an ID number Permutated blocks will be used to allocated individuals to one of the three groups. ID number will be sent to an off site individual who will randomly allocated particpants. The person who determined if a subject was eligible for inclusion in the trial was unaware, when this decision was made, to which group the subject would be allocated. Allocation was concealed if it was done by the off site individual using sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permutated blocks will be used to randomise particpants to one of three groups. An envelop method will be used.
Masking / blinding
