An interventional study of Polar Loop 2 activity tracker in Exercise, Aging and Retirement, sponsored by University of Turku. Completed at 1 site in Finland. Open to participants aged 60 Years to 65 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2020-06-30.
Sponsored by University of Turku · Not applicable, Interventional, and Treatment
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.
9,798 studies on the registry are indexed under Motor Activity; 1,910 are open to participants now.
This study's enrollment of 231 is above the median of 60 across 8,388 interventional studies indexed under Motor Activity.

Exclusion Criteria:
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
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.
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.
