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).

Secondary outcome [1] 299520 0
Useful field of view test (UFOV). This is a measure of the extent to which individuals are capable of extracting visual information in a given moment without movement of the eyes or head, as an indicator of driving skill.

At pre-intervention and post-intervention (4 weeks)
Secondary outcome [2] 299521 0
Forced Expiratory Volume. This measures lung capacity to examine relative physiological effects of the interventions. It is measured using a device called a spirometer.

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.

Summary
Brief summary
Normal cognitive ageing is characterised by slowing of information processing and a decline in a range of cognitive abilities that involve problem solving, attention, working memory, episodic memory and executive function. Cognitive ageing only interferes with daily activities when there are complex cognitive demands occurring jointly with sensory and physical demands.

In order to improve everyday function in older adults, we aim to develop an intervention targeting both complex cognitive demands and physical demands. As a pilot study, we aim to compare executive function training with a physical activity intervention (Jazzercise), compared with a comparison group receiving no intervention, on everyday function outcomes including a driving simulator task.
