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 .
Aerobic Interval Training Reduces the Burden of Atrial Fibrillation in the Short Term: A Randomized Trial
Background — Exercise training is an effective treatment for important atrial fibrillation ( AF ) comorbidities . However , a high level of endurance exercise is associated with an increased AF prevalence . We assessed the effects of aerobic interval training ( AIT ) on time in AF , AF symptoms , cardiovascular health , and quality of life in AF patients . Methods and Results — Fifty-one patients with nonpermanent AF were r and omized to AIT ( n=26 ) consisting of four 4-minute intervals at 85 % to 95 % of peak heart rate 3 times a week for 12 weeks or to a control group ( n=25 ) continuing their regular exercise habits . An implanted loop recorder measured time in AF continuously from 4 weeks before to 4 weeks after the intervention period . Cardiac function , peak oxygen uptake ( O2peak ) , lipid status , quality of life , and AF symptoms were evaluated before and after the 12-week intervention period . Mean time in AF increased from 10.4 % to 14.6 % in the control group and was reduced from 8.1 % to 4.8 % in the exercise group ( P=0.001 between groups ) . AF symptom frequency ( P=0.006 ) and AF symptom severity ( P=0.009 ) were reduced after AIT . AIT improved O2peak , left atrial and ventricular ejection fraction , quality -of-life measures of general health and vitality , and lipid values compared with the control group . There was a trend toward fewer cardioversions and hospital admissions after AIT . Conclusions — AIT for 12 weeks reduces the time in AF in patients with nonpermanent AF . This is followed by a significant improvement in AF symptoms , O2peak , left atrial and ventricular function , lipid levels , and QoL.
