AbstractIntroductionIncreased physical exercise is linked to enhanced brain health and reduced dementia risk. Exercise intervention studies usually are conducted at facilities in groups under trainer supervision. To improve scalability, accessibility, and engagement, programs may need to be structured such that individuals can execute and adjust routines in their own homes.MethodsOne hundred eighty‐three healthy older adults from two sites (the United States and Sweden) were screened. One hundred fifty‐six subjects (mean age 73.2), randomly assigned to one of four interventions (PACE‐Yourself physical exercise program, mindfulness meditation, or Cogmed® adaptive or nonadaptive computerized working memory training) began the study. All interventions were structurally similar: occurring in subjects' homes using interactive, web‐based software, over five weeks, ∼175 minutes/week. In the PACE‐Yourself program, video segments presented aerobic exercises at different pace and intensity (P&I). The program paused frequently, allowing subjects to indicate whether P&I was “too easy,” “too hard,” or “somewhat hard.” P&I of the subsequent exercise set was adjusted, allowing subjects to exercise at a perceived exertion level of “somewhat hard.” Program completion was defined as finishing ≥60% of sessions.ResultsA high percentage of participants in all groups completed the program, although the number (86%) was slightly lower in the PACE‐Yourself group than the other three. Excluding dropouts, the PACE‐Yourself group had a lower adherence rate of 93%, compared with the other three (∼98%). Over the five weeks, PACE‐Yourself participants increased exercising at the highest intensity level, consistent with augmented aerobic activity over time. The number of exercise sessions completed predicted the postintervention versus preintervention increase in self‐reported level of physical activity.DiscussionThis study supports the feasibility of a home‐based, subject‐controlled, exercise program in which P&I is regulated via real‐time participant feedback, which may promote self‐efficacy. Further study is needed to determine if similar results are found over longer periods and in more diverse populations.
