Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1. Cognitive training. This will be conducted in small groups by a research assistant, 1 hour sessions 3x per week for 4 weeks. It will involve tasks dedicated to executive function training, especially as it relates to driving ability. Most tasks will be computer-based. Goal: To provide training and strategies that focus on executive control of movement.
Arm 2. Physical activity. This will be conducted in small groups by a research assistant, 1 hour sessions 3x per week for 4 weeks. It will involved Jazzercise, a dance-based physical activity program specifically tailored to this age-group, and designed to be cognitively challenging exercise (e.g., remembering patterns and steps, pattern changes etc).

Study design
Purpose of the study
Educational / counselling / training
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Information forms about the project will be distributed to a retirement village. These information sheets will include contact details of researchers for those who wish to participate in the study. Once participants have indicated their interest, provided signed consent and found eligible for the trial according to inclusion and exclusion criteria, they will be randomly allocated to one of three conditions by an independent researcher.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by using a randomization table created by a computer software (i.e. computerised sequence generation). After administration of the baseline measures and providing consent to participate, each individual will be randomly assigned to one of the three conditions according to their sex. This stratification to condition will help to ensure approximately equal numbers of males and females in each group.
