Discussion
We observed a significant increase in LPA at the end of the training in the SE-UBR group compared with the two control groups. In contrast, the control groups decreased LPA by 22 and 26 minutes/day each. Changes in LPA were not accompanied by self-reported changes in functional performance. The gains in LPA for the SE-UBR group (relative to the control groups) were not sustained at 12 months after the end of training. There was no change in the time spent in MVPA or in sedentary activity.
