The aim of this trial is to compare the effectiveness of center-based versus home-based physical activity delivery among people with MCI and early dementia and to understand the influence of person and setting characteristics.
Primary: To compare the effectiveness of centre-based versus home-based physical activity delivery among people with MCI or early dementia, as measured by percent achievement of physical activity guidelines.
(i) To determine the influence of person- and setting-specific factors. (ii) To estimate the cost-effectiveness of centre-based and home-based physical activity.
i) To compare the effect of centre- and home-based physical activity on other outcomes.
ii) To explore whether participants consider certain aspects of the program to be important to program effectiveness.
The investigators will conduct a 3-month proof-of-concept, double-blinded randomized, parallel group trial to compare the effectiveness of centre-based and home-based physical activity in helping people with MCI and early dementia meet physical activity recommendations.
Participants will be randomized to one of two physical activity delivery options.The goal of both arms will be to have participants reach physical activity guidelines by the end of the 3-month intervention.
Participants who are randomized to centre-based physical activity will attend physical activity programming at a centre (University of Waterloo or Toronto Rehabilitation Institute) once per week for one hour. Additional physical activity will be prescribed at home.
Participants who are randomized to the home-based physical activity will received a physical activity prescription to be completed at home. They will also receive monthly support calls to assess achievements and barriers and to adjust the prescription.
All assessors will be blinded to group allocation.

Experimental: Centre-based physical activity
People with Mild Cognitive Impairment (MCI) and early dementia will receive centre-based physical activity for one hour each week for three months, plus at-home prescribed exercise.
Behavioral: Centre-based exercise
Participants will come to a centre (University of Waterloo or Toronto Rehabilitation Institute) for a one-hour, small group exercise class each week. The classes will include progressive aerobic and resistance exercise. They will be prescribed additional exercise to be performed independently (either at home or in the community).
Experimental: Home-based exercise
People with Mild Cognitive Impairment (MCI) and early dementia be prescribed at-home prescribed exercise and will received monthly support phone calls.
Behavioral: Home-based exercise
Participants will be prescribed aerobic and resistance exercise to be performed independently (either at home or in the community). They will receive monthly phone calls to discuss achievements and barriers and to tje adjust exercise prescription.
