NCT03320746

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.

Study Arms (2)

Activity trackers

EXPERIMENTAL

The participants were requested to wear a commercial wrist-worn activity tracker (Polar Loop 2, Polar, Kempele, Finland) every day and night for 12 months.

Device: Polar Loop 2 activity tracker

No activity trackers

NO INTERVENTION

Control group members were requested to abstain from the use of any type of activity trackers and they were informed that they will receive the activity trackers and guidance for using them after the follow-up.

Interventions

Polar Loop 2 activity trackerDEVICE

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.
