Purpose: Verify the effects of periodical multicomponent exercise training and detraining on the physical function in older adults with dementia. Method: Seventeen older adults with dementia (mean age 72, MMSE 17.8) performed multicomponent exercise twice a week for a total of 18 months. The assessment was made six times: 1) at the baseline, 2) 24 weeks of training, 3) 12 weeks of first detraining, 4) 12 weeks of retraining, and 5) 12 weeks of second retraining after second 12 weeks of detraining. Sit to stand, arm curl, 8 feet Time to up and go, 4-meter walk test, Short Physical Performance Battery were assessed. Nonparametric Friedman's test and Wilcoxon matched pairs signed rank test was conducted with an alpha-level of 0.05. Results: Significantly training-related improvements for the sit to stand, arm curl, 8-foot TUG, 4-meter walk, and SPPB. Following two times of 12 week-detraining and retraining, significantly enhanced performance (compared to baseline) was still presented in sit to stand and insignificantly maintained performance (compared to baseline) was presented in arm curl, 8-foot TUG, 4-meter walk and SPPB. Conclusion: The present study tested and confirms that the effect of periodical multicomponent exercise training and detraining improved or maintained physical function in older adults with dementia.
