Brief summary
The purpose of REACT project is to provide cost-effective way to promote physical activity and reduce sedentary time among older adults. This is done by examining the efficacy of activity tracker based intervention on wake-time physical activity, sedentary time, sleep and other health outcomes among recent retirees. REACT study will be the first randomized physical activity trial targeted to time window right after retirement.
Interventions
DEVICEPolar Loop 2 activity tracker
The participants were instructed to aim to reach the daily activity goal, initially set at stage 1 as per the goals set by the trackers' manufacturer. The daily activity goal was based on user's typical daily activities, gender and age. The stage 1 daily activity goal corresponded to \ 1h/day of jogging or \ 2h/day of walking or \ 7h/day household activities or a combination of these activities. The tracker gave an inactivity alert as a vibration and text it's time to move on the screen of the tracker if the user has been still for 55 minutes.
