Plain-language summary
Aerobic exercise is an evidence-based approach to mitigate cognitive decline in older adults with mild cognitive impairment (MCI). Emerging evidence suggests that the cognitive benefits of exercise may be enhanced when performed in outdoor, natural settings, as compared to indoor or built settings. Thus, the investigators aim to compare the effects of outdoor versus indoor walking programs on cognitive function among older adults with MCI. Secondary outcomes are motor function, emotional well-being, health-related behaviours, and quality of life. Participants will be randomly assigned to a 12--week, 3x/week program of either outdoor walking on forest trails or indoor walking on a treadmill. A 3-month followup will also be completed after trial completion.
