![]() ![]() In PROMOTE II, participants were randomized to either (1) a print-based intervention or (2) a web-based intervention, whereby 30% of the web-based intervention group (selected at random) also received an activity tracker. Participants of PROMOTE I were randomized to either (1) a web-based intervention, (2) a web-based intervention plus self-monitoring via wearing an activity tracker to track and evaluate their own daily PA, or (3) a waitlist control group (CG). PROMOTE, one of the network’s six subprojects, aims to promote a physically active lifestyle the subproject was conducted in two study phases with similar community-based interventions (PROMOTE I, 2015–2018 PROMOTE II, 2018–2021 ). One aim of the network is to develop, implement and evaluate PA interventions to prevent chronic diseases in community-dwelling older adults (60 years or older). ![]() This study is a subproject of the two PROMOTE studies (PROMOTE I and PROMOTE II), which belong to the larger research network “Physical activity and Health Equity: Primary prevention for healthy aging” (AEQUIPA) funded by the Federal Ministry of Education and Research (BMBF) in Germany. In sum, evidence about the impact of PA interventions conducted at home (e.g., print- or web-based programs) supported by activity trackers on the cognitive and physical function of older community-dwelling adults is limited. Few studies have investigated the additional effect of activity trackers, and those that have tend to report PA behavior as the main outcome, not physical and cognitive function. However, the impacts of PA interventions conducted at home (e.g., print- or web-based interventions) compared to interventions that also include objective PA monitoring (i.e., via activity trackers) on cognitive and physical function in community-dwelling older adults have not yet been systematically examined. Indeed, other studies examining the effects of activity tracker interventions on health outcomes in older adults or patients indicate positive effects (e.g., on body mass index (BMI), blood pressure, muscle strength, physical function, LDL cholesterol levels). These results suggest that, via increases in PA levels, activity trackers may have an additional impact on health outcomes, such as cognitive and physical function. In another study, Muellmann and colleagues investigated the benefit of using activity trackers in addition to a website to monitor PA in German older adults they found that in the group using an activity tracker for three months, compared to the non-tracker group, there were slight, though non-significant, increases in moderate-to-vigorous PA (MVPA) and decreases in participants’ sedentary time. ![]() For example, in a study by Compernolle and colleagues, a combined computer-tailored, pedometer-based PA intervention increased objective and subjective PA levels in working adults (≥18). Activity trackers might be an effective interventional approach, in that their usage can improve PA behavior. Findings suggest that a combined web-based and activity tracker intervention may improve physical functions, physical self-concept, and cognition in community-dwelling older adults.Īdditionally, objective monitoring instruments, such as activity trackers, are becoming increasingly popular and have been used for interventions in both younger and older community-dwelling populations. We found the highest effect sizes in all measured dimensions for AG (grip strength, endurance, gait speed, reaction time, physical self-concept), followed by IG (endurance, gait speed, reaction time, physical self-concept) and CG (endurance, gait speed, BIS). Measured parameters were grip strength, endurance (two-minute step test), gait speed (four-meter walk test), cognition (Simon task balanced integration score (BIS), reaction time and accuracy) and physical self-concept (Physical Self-Description Questionnaire (PSDQ)). Data of participants ( n = 551, 60–80 years) were analyzed after being randomly allocated to a waitlist control group (CG), a web-based or print-based intervention group (IG) or a web-based intervention group that also included the use of an activity tracker (AG). web-based plus the use of an activity tracker) on cognitive and physical health parameters in older adults. Thus, we aimed to compare the effectiveness of two physical activity interventions primarily conducted at home (print-based or web-based vs. Regular physical activity (PA) is of central importance for healthy aging and has a well-known impact on helping older adults maintain their cognitive and physical health. ![]()
