abstract = {Although the health benefits of physical activity (PA) are well known, the majority of adolescents are not sufficiently physically active. New innovative ways to promote active lifestyles are needed. This study aimed to evaluate the effectiveness of a wrist-worn activity monitor (Polar Active) and a gamified web-based mobile service in promoting PA in young men. The study also examined the convergent validity between three different accelerometer-based PA measurement methods.
In this study, two randomized controlled trials (RCT) were conducted in Oulu, Finland among 18-year-old men. The three-month RCT (n=276) was conducted in fall 2012 and the six-month population-based RCT (n=496) between September 2013 and March 2014. In both trials, participants were randomized to an intervention and a control group. The intervention group was given the wrist-worn Polar Active monitor with PA feedback. In the six-month trial, the intervention group also got access to a mobile service developed in this study. During both trials, PA was continuously measured in both study groups. In the control group, PA was measured with an otherwise similar monitor but which provided only the time of day and no feedback. The convergent validity was examined between the agreement in time spent at different PA levels using Polar Active, mean amplitude deviation (MAD) of raw acceleration, and Actigraph with the Freedson thresholds. In the validation study, all three activity monitors were continuously used for two weeks by 41 volunteers.
The three-month trial had a short-term positive effect on daily moderate-to-vigorous PA (MVPA) and sedentary time in the intervention group. The positive change in sedentary time was sustained for longer. During the six-month trial, a positive trend in favor of the intervention group was observed in daily MVPA. Low amount of daily vigorous PA at baseline was associated with the increase in MVPA. The functionalities of the mobile service related to PA were perceived as important and motivating, but the overall compliance with using the service and activity monitor remained low. In free-living conditions, the agreement between Polar Active, MAD, and Actigraph was dependent on the activity thresholds used and PA intensity. The information provided by this study can be utilized in future development of technology-based health services for activating young people.},

abstract = {Physical inactivity and sedentary behaviour (SB) are harmful to health, but both globally and in Finland, 80% of adolescents are not physically active enough and they sit too much. Unhealthy behaviour seems to accumulate in young men. Factors underlying unhealthy behaviour should be identified, and based on these, effective interventions for health promotion should be developed. In this study we aimed to clarify the determinants of physical activity (PA) and SB in young men. In addition, we studied the effects of a gamified, tailored, mobile PA intervention on PA and subjective wellbeing.
Population-based data were collected in call-ups organized by the Finnish Defence Forces in 2010, 2012 and 2013 in the Oulu area, Finland. Altogether 2526 approximately 18-year-old men filled in a questionnaire, attended physical performance tests and went through a medical examination. In 2013, all 811 men who attended physiological measurements were invited to participate in a six-month randomized controlled trial, and 496 (61%) of them agreed to do so and were randomized into intervention (n=250) and control (n=246) groups. The intervention group got access to a mobile service developed in this study. PA and SB were continuously monitored during the trial. The PA and SB of the controls was measured without feedback on behaviour.
The profiles “exercising but sitting”, “feeling unhappy”, “symptoms of disordered eating”, “being unfit with appearance-related motivation” and “gaming” were found among the sedentary young men. The men living in both built and natural environments were equally physically active. The mother’s PA was associated with PA in men living in the built environment and the father’s PA with PA among natural environment residents. The intervention had a borderline positive effect on moderate-to-vigorous PA, but there was no change in SB or light PA. Life satisfaction improved both in the intervention group and the control group. Various functionalities related to the PA of the mobile service were considered important. However, the compliance in using the service was limited. Improvements in PA, self-rated health and life satisfaction were seen, especially among the men in the intervention group with low levels of PA and poor subjective wellbeing at baseline.
This study complements existing knowledge on the PA and SB of youth and the findings on the effects of technology-based PA promotion. The study adds to literature on individual, environmental and parental factors underlying SB and PA in young men.
