Video-supervised exercise improved movement tests, but not blood sugar
Among 33 adults with type 2 diabetes, those who trained remotely improved more on movement and sleep tests. Blood sugar did not differ.
The study, in plain language
Supervision took place by video while participants did aerobic and strength exercises. Over 12 weeks, a trial in Pelotas, Brazil, compared this approach with no program among adults with type 2 diabetes who did not use insulin and were not regularly active. The people assessing and analyzing the data did not know each participant's group.
The primary measure, which reflects blood sugar over the past few months, showed no convincing difference. Some movement tests favored the remote group: standing up from a chair, arm work, moving around, and completing a step test. Participants also reported improved sleep quality. These were secondary outcomes in a small, single-center study, and several people left the program.
The key idea
Average blood sugar did not change convincingly, but several movement tests and participant-reported sleep favored the training group.
Something to think about
When a study does not change its primary measure, what else changed? Here, blood sugar did not change convincingly, but some movement tests did. The group was small.
