Both groups underwent a twice-weekly, 8-week center-based exercise intervention with aerobic and resistance exercises. EX+NEPA group also received a wearable activity tracking device along with behavioral monitoring and feedback throughout the study. Study outcomes were evaluated at 8 and 20 weeks.Results: Data are presented as adjusted mean change of the differences over time with 95% confidence intervals at 20 weeks. Relative to EX, the change in steps/day at 20 weeks was 1994 (−40.27, 4028) higher for EX+NEPA. For sedentary time at close-out, the EX+NEPA group was −6.8 (−45.2, 31.6) min/day relative to EX. The between-group differences for systolic and diastolic blood pressure were −9.9 (−19.6, −0.3) and −1.8 (−6.9, 3.3) mmHg, respectively.Conclusion: The addition of wearable technology intervention appeared to positively influence daily activity patterns and changes in blood pressure – potentially improving risk factors for CVD. A fully powered randomized trial is needed to ultimately test this hypothesis.Keywords: aging, cardiovascular, exercise, physical activity, activity monitorRoberts LMJaeger BCBaptista LCHarper SAGardner AKJackson EAPekmezi DSandesara BManini TMAnton SDBuford TWDove Medical PressarticleAgingcardiovascularexercisephysical activityactivity monitorGeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 14, Pp 1817-1828 (2019)
