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 .
Impact of increasing physical activity on cognitive functioning in breast cancer survivors: Rationale and study design of Memory & Motion.
INTRODUCTION Many breast cancer survivors experience problems with  cognitive functioning  that can persist years after treatment . Increasing physical activity has been shown to improve cognitive functioning in healthy and cognitively impaired adults , but has not yet been tested in cancer survivors . The primary aim of this r and omized controlled trial is to examine the effects of a 3-month physical activity intervention compared to a waitlist Control arm on neuropsychological outcomes and subjective cognitive concerns in breast cancer survivors . METHODS Eighty sedentary breast cancer survivors , self-reporting difficulties with cognition , will be r and omized into an Exercise arm or Control arm . The Exercise arm includes an activity tracker ( i.e. , a Fitbit ) , phone calls , plus tailored and non-tailored email content . The Control arm will receive emails on women 's health topics on the same schedule as the Exercise arm . Assessment s conducted at baseline and 3 months include : neuropsychological testing , cognitive concerns and other aspects of quality of life , and 7 days of a hip-worn accelerometer . Participants will also provide fasting blood draws to assess brain-derived neurotropic factor , Insulin-like growth factor 1 , insulin resistance , and C-reactive protein . Primary and secondary outcomes are changes in neuropsychological testing and cognitive concerns . Biomarkers will be examined to further underst and the underlying relationship between physical activity and cognition . CONCLUSION The Memory & Motion study is design ed to test whether increasing physical activity can improve cognitive functioning in breast cancer survivors . Results from this study could be used to guide development of interventions to improve cognitive functioning in breast cancer survivors
