Study Summary
This pilot study is a small sample (N=46) 16-week clinical trial with a follow-up after 24-weeks among sedentary adults \>60 y with a BMI \>25 kg/m2 to tests the impact of a hybrid artificial intelligence behavior change system (Companion) on physical activity. Participants will be randomized to a control and intervention group. All participants will engage in a proven supervised exercise program from week 1 to 16. Only the intervention group will receive Companion from week 1 to 16.
Primary Outcome
Total time spent being active will be measured using a body worn motion sensor (accelerometer) during waking hours over a period of one week. Measures for each day (hours) will be averaged to obtain a representative estimate of daily habitual behavior.
