Exercise adherence in mild cognitive impairment was reported inconsistently
A review examined how exercise participation was defined and tracked, finding varied reporting and differences across program characteristics.

The 30-second takeaway
The review found substantial inconsistency in how exercise adherence was defined and reported among people with mild cognitive impairment. It summarized participation alongside supervision, incentives and program duration, but these summaries do not establish which feature improves adherence. The outcome was engagement with exercise, not a change in memory or cognition.
Definitions were inconsistent, and the abstract presents average adherence and its confidence interval on different scales. It also gives no direct tests isolating the effects of supervision, incentives or program length.
What adherence meant
Only a small subset of studies explicitly defined adherence as the share of sessions attended. Without a consistent definition, reported adherence rates cannot automatically be interpreted as the same measure of participation across programs.
Duration comparisons need care
Studies of longer programs reported lower average adherence than the shorter-duration groups described in the abstract. These were summaries across different studies, so they do not prove that extending a program causes people to participate less.
