Conclusion This review indicates that current research on activity monitoring devices may be overstated due to the variability in adherence .
Results showed that physical activity tracking in women and in young adults have been understudied
Background Activity monitoring devices are currently being used to facilitate and monitor physical activity .
No prior review has examined adherence to the use of activity monitoring devices amongst adults with cardiovascular disease .
Exercise-based cardiac rehabilitation increases daily physical activity of patients following myocardial infarction: subanalysis of two randomised controlled trials.
OBJECTIVE To assess the effects of an exercise-based cardiac rehabilitation programme on daily physical activity levels of patients following myocardial infa rct ion . DESIGN Sub analysis of two r and omised , prospect i ve controlled trials . SETTING Outpatient clinic of a secondary hospital . PARTICIPANTS Fifty consecutive patients r and omised to the exercise group { n=25 ; 23 males ; mean age 54 [ st and ard deviation ( SD ) 9 ] years } or the control group [ n=25 ; 20 males ; mean age 58 ( SD 9 ) years ] . INTERVENTIONS The exercise group participated in an 8-week aerobic exercise programme plus usual medical care and follow-up . The control group received usual medical care and follow-up . MAIN OUTCOME MEASURES The primary outcome measure was change in time spent undertaking moderate-to-vigorous physical activity per day , assessed by accelerometer over 7 consecutive days . Secondary outcome measures were cardiorespiratory fitness , body mass , and resting blood pressure and heart rate . RESULTS Moderate-to-vigorous physical activity levels increased significantly in the exercise group [ 43.2 ( SD 36.3 ) to 53.5 ( SD 31.9 ) minutes/day , P=0.030 ] , and remained unchanged in the control group [ 40.8 ( SD 26.2 ) to 36.8 ( SD 26.5 ) minutes/day , P=0.241 ] from baseline to the end of the programme . Cardiorespiratory fitness increased significantly in the exercise group ( mean difference 2.8 ; 95 % of the difference 1.3 to 4.4ml/kg/minute , P=0.001 ) after the 8-week programme . CONCLUSIONS In patients under optimal medication following myocardial infa rct ion , participation in an 8-week exercise-based cardiac rehabilitation programme was found to improve physical activity levels consistent with health-related benefits . Future studies are needed to determine whether the increase in physical activity is maintained in the long term
