Exercise: The intervention will involve online (via University of British Colombia (UBC) Zoom videoconferencing) 1-hour moderate to high intensity exercise classes 3 times a week for 6 months
Meditation: The intervention will involve 15 minute guided mediation following exercise classes as well as mindfulness classes.
Mindfulness classes will consist of 1.5 hour Mindfulness Based Stress Reduction (MBSR) classes for the first 2 months, followed by 1 month of 1 hour bi-weekly discussions and practice, then MBSR 2.0 for months 4 and 5, and 1 hour bi-weekly discussions and practice for the remaining month of the intervention.
Diet: The intervention will involve biweekly 1-hour nutrition and cooking classes with a dietician.
Study summary
The Impact 360 study will evaluate the effects of a combined intervention of exercise, mindfulness, and nutrition on 8 key indicators of health and the mechanisms that drive these changes. 60 subjects aged 50 to 75 without a current diagnosis of a brain disorder will be recruited. This study will follow a partial crossover design. All participants will receive the intervention. Participants randomized into the intervention group after their baseline screening will receive the 6-month intervention. Those randomized into the waitlist group will complete another assessment at the end of the 6-month care as usual phase before receiving the intervention.
