Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1 intervention - ballroom dancing twice weekly for 1 hour over 9 months. A collection of dances such as Rock and Roll, Foxtrot, Waltz and some Latin (Salsa and Rumba) will be taught in the course. A common principle is that each dance can be taught at various levels of complexity (eg. Foxtrot: Basic steps, Promenade, Rock Turn, and Sway). The program will be held in a dance studio or community hall. Intensity levels during dance classes will be measured by accelerometers and the Perceived Physical Effort scale (PPE). The program will be standardised across all studios and will be delivered by accredited dance Instructors who will attend three 1-hour workshops, at start and two 3-month apart led by the program coordinator. In the workshops teachers will receive the program resources for the next two months (CDs and workbook, raise problems encountered in previous stage and discuss class progress).

Comparator / control treatment
Arm 2 – will receive a combination of a home and group-based walking program at the same dose of intervention (2 x 1 hour sessions) over 9 months. The walking program will involve some "cognitive tasks", using pedometers and accelerometers, and will provide opportunity to socialise by walking in teams.
The walking program consists of three stages, each stage last 12 weeks. Group meetings will be held once every fortnight in a designated park in the area, the complementary walks of the week can be done at different parks according to participants’ residential areas and will be encouraged to work in teams or pairs.
In the first stage participants will engage in short walk at a convenient pace with a focus on a pedometer. The intermittent walks (10min*3) or (15min *2) or (20min*2) during a session of an hour in which they observe: 1) the number of steps undertaken at each interval 2) distance of the intermittent walks at an easy pace using their stride length entered and saved in their pedometers and 3) the approximation of calories expended during those intermittent walks using their body weight saved in their pedometer. Participants will repeat without the instructor what they have done in the last fortnight session. In the second stage (week 13-24) participants will engage in longer walks (30 minutes -45minutes) without interruption at a convenient pace (with pedometers) and will learn the principles of assessing perceived effort using the Borg scale, heart reserve, and objective measurement of intensity of the walk by wearing accelerometers. They will receive personal feedback on the intensity measured during this walks. The aim is to maintain similar effort to dance classes. In the third stage (week 25-36) the focus of the program will shift to brisk walking (with pedometer & accelerometer) ; participants will practice increasing the number of steps undertaken in 10 minutes compare to first stage - establishing individual 's "brisk walk" equivalent steps per 10 minutes and will engage in intervals of walking at brisk and convenient pace for one hour.

Outcomes
Primary outcome [1] 289632 0
Trial Making Test part A (TMT-A) and part B (TMT-B): Part A measures processing speed and involves the participant connecting consecutive numbers. Part B is a measure of executive function of "task-shifting" and involves participant connecting a series of circles alternating between letters and numbers (e.g. 1-A-2-B-3-C). Time (seconds) to complete each test is recorded and the difference in time between TMTB and A will be used as indication of executive function .
Timepoint [1] 289632 0
The second baseline measurement (3 weeks from baseline) will be compared to 9 months measurement . This is to wash out the effect of improvement due to "learning" from repetition.
Primary outcome [2] 289674 0
The Stroop Color-Word Test is measuring the person’s ability to suppress automatic reactions in favour of alternative choice reactions, and is indicative of mental flexibility. It requires concentration and ability to ward off distractions. Participants are shown a page with Color-Word printed in non-matching ink (i.e. the word BLUE is printed in red). In the first part they are asked to read a list of words and the time it takes is recorded. In the second part they are asked to name the ink color in which the word are printed (i.e., ignoring the word itself). The score is the number of correct words

The second baseline measurement will be conducted 3 weeks following the initial baseline measurement and will be compared to 9 month measurement session.
Primary outcome [3] 289675 0
Digit Span Backward (DSB) will be used to measure working memory. The tests involved recalling digits in reverse order (DSB). Seven pairs of random number sequences are read to participants. The sequence begins with three digits and increase by one at a time up to 9 digits. The number of correctly recalling sets (range from 0-14) are recorded.

The second baseline measurement will be conducted 3 weeks following the initial baseline measurement and will be compared to 9 month measurement session.
Secondary outcome [1] 302896 0
Colour Choice Reaction Time (CRTC): The test involves the presentation of targets of different colours in one of four cells in a square grid. Participants respond to targets by using hand buttons or foot pedals. Blue target requires a response inhibition (i.e., not pressing any buttons). The computer recorded reaction times and accuracy for each of 60 trials.

Secondary outcome [2] 302983 0
Stroop Step Choice Reaction Time measures response inhibition and selective attention. For this test eight panels on the dance mat are used: 2 central stance panels, 2 front panels, 1 left panel, 1 right panel and 2 back panels. In the centre of the computer screen an arrow is presented pointing in one of four directions (up, down, left, right) that match the four possible step directions (forward, backward, left, right). Inside the arrow is a written word indicating a direction different to that indicated by the arrow. Participants have to step according to the word (ignoring the direction of the arrow) and then return to the centre panels. After 4 practice trials with one step in each direction, a random sequence of 20 trials in which the directions of word and shape never match commences. Participants step with the left foot to the left panel, with the right foot to the right panel and with either foot to the front and back panels. If participants step on a wrong panel they have to repeat the trial until they step correctly. In each of the three tests, reaction time measured from stimulus occurrence to movement initiation (lift off); movement time measured from movement initiation to step finalisation (step down) and stepping errors are measured.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
1. Determine if the participant is eligible for the study -
2. Participants at risk completes the consent form and gets GP clearance to participate in moderate physical activity
3. Complete first baseline measures - time_0 - baseline, time_1 - about 3 weeks following time 0 measurements.
3. Using sealed opaque envelopes eligible participants who completed two baseline measurements and consented will be randomized.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The group allocation scheme used randomized permuted blocks using computer –generated random numbers.

Efficacy
Statistical methods / analysis
Based on previous research, aerobic exercise with simultaneous cognitive stimulation achieved an effect size of 0.5 on executive functioning tests in comparison to aerobic training only. We assumed that Dance as aerobic and mental activity will achieved this effect over walking on the main executive functions tests. Power analysis was therefore based on this effect size and an attrition rate of 18%, yields a sample size of 126 (power=.80, alpha=.05). The difference in change in scores between the two groups will be initially tested by an independent t-test of the change scores (i.e., second baseline measurement to 9 months). Further analyses using linear mixed models for continuous outcomes and generalized linear mixed models for discrete outcomes with group allocation as the between-subjects effect will allow for simultaneous comparisons across all three time points with the inclusion of covariates. An intention-to-treat approach will be taken.
