    Physical activity (PA) is necessary for young children. The new recommendations for physical activity in early childhood in Finland suggest that daily activity consists of at least 3 hours of light-to-vigorous physical activity (LMVPA). In this article, we report preschool children’s compliance with the recommendations, PA amounts at different intensity levels, the variation between genders, and the effect of weekend on PA. The data were collected from 172 children, aged 3 to 7 years, using accelerometers during January–March 2015 for 7 days, 24 hours per day. Results revealed that compliance with the recommendations is low: 43% of the boys and 32% of the girls engaged in LMVPA for at least 3 hours per day. The variation was remarkable. Moderate-to-vigorous physical activity (MVPA) averages ranged from 16 to 154 minutes in boys, and from 4 to 98 minutes in girls. The weekend decreased PA at all intensity levels and increased sedentary behavior by approximately 60 minutes (p < .001, = .39) in both genders. Interventions should focus on girls as a group, on boys with minimal amounts of MVPA, on reducing sedentary behavior, and on increasing weekend activity.

    Purpose The randomized controlled trial REACT (NCT03320746) examined the effect of a 12-month consumer-based activity tracker intervention on accelerometer-measured physical activity among recent retirees. Methods Altogether 231 recently retired Finnish adults (age, 65.2 +/- 1.1 yr, mean +/- SD; 83% women) were randomized to intervention and control groups. Intervention participants were requested to wear a commercial wrist-worn activity tracker (Polar Loop 2; Polar, Kempele, Finland) for 12 months, to try to reach the daily activity goals shown on the tracker display, and to upload their activity data to a Web-based program every week. The control group received no intervention. Accelerometer-based outcome measurements of daily total, light physical activity (LPA), and moderate to vigorous (MVPA) physical activity were conducted at baseline and at 3-, 6-, and 12-month time points. Hierarchical linear mixed models were used to examine the differences between the groups over time. All analyses were performed by intention-to-treat principle and adjusted for wake wear time. Results The use of a commercial activity tracker did not increase daily total activity, LPA, or MVPA over the 12-months period when compared with nonuser controls (group-time interaction, P = 0.39, 0.23, and 0.77, respectively). There was an increase in LPA over the first 6 months in both the intervention (26 min center dot d(-1), 95% confidence interval [CI] = 13 to 39) and the control (14 min center dot d(-1), 95% CI = 1 to 27) groups, but the difference between the groups was not significant (12 min center dot d(-1), 95% CI = -6 to 30). In both groups, LPA decreased from 6 to 12 months. Conclusion The 12-month use of a commercial activity tracker does not appear to elicit significant changes in the daily total activity among a general population sample of recent retirees, thus highlighting the need to explore other alternatives to increase physical activity in this target group.
