CONCLUSIONS Utilizing a consumer-based wearable activity tracker as either the primary component of an intervention or as part of a broader physical activity intervention has the potential to increase physical activity participation .
BACKGROUND The range of benefits associated with regular physical activity participation is irrefutable .
Despite the well-known benefits , physical inactivity remains one of the major contributing factors to ill-health throughout industrialized countries .
Traditional lifestyle interventions such as group education or telephone counseling are effective at increasing physical activity participation ; however , physical activity levels tend to decline over time .
Consumer-based wearable activity trackers that allow users to objective ly monitor activity levels are now widely available and may offer an alternative method for assisting individuals to remain physically active .
OBJECTIVE This review aim ed to determine the effects of interventions utilizing consumer-based wearable activity trackers on physical activity participation and sedentary behavior when compared with interventions that do not utilize activity tracker feedback .
Promoting physical activity using an activity monitor and a tailored web-based advice: design of a randomized controlled trial [ISRCTN93896459]
Background Ageing is associated with a decrease in physical activity . This decrease particularly occurs during specific transitional life stages . Especially during adolescence and young adulthood a steep decrease in physical activity is observed . Inactive people are often not aware of their inactivity . Providing feedback on the actual physical activity level by an activity monitor can increase awareness and may in combination with an individually tailored physical activity advice stimulate a physically active lifestyle . Methods In a r and omized controlled trial the effectiveness of providing an activity monitor in combination with a personal physical activity advice through the Internet will be examined . Outcome measures are level of physical activity , determinants of physical activity , quality of life , empowerment , aerobic fitness and body composition .  Participants are relatively inactive adolescents and young adults who are measured at baseline , after 3 months intervention and 5 months after the end of the intervention . In addition , facilitating and hindering factors for implementation of the intervention will be investigated . Discussion The use of a personal activity monitor in combination with web-based assisted individually tailored health promotion offers a good opportunity to work interactively with large groups of adolescents and young adults and provide them with advice based on their actual activity level . It has great potential to motivate people to change their behaviour and to our knowledge has not been evaluated before
