Abstract Introduction:<\b>
Residential aged care facilities, care for a growing number of older adults experiencing significant dementia-related problems. There are insufficient scientifically tested, cost-effective, non-pharmacological, dementia-specific interventions designed to improve behavioural, psychological and physical symptoms of dementia. This study assesses the physical activity and sedentary behaviour outcomes of the aquatic exercise intervention – the Watermemories Swimming Club. Methods:<\b>
A feasibility study for a cluster-randomised controlled trial with two groups. The exercise participants undertook an aquatic exercise program in twice weekly, 45 minute sessions for 12 weeks, using trained accredited swimming/aqua aerobic instructors. Controls received usual care. At each data collection (pre and post intervention), participants wore a GT9X actigraph accelerometer on their non-dominant wrist. Raw data was processed using the GGIR R-software package. Outcome variables sedentary, light and moderate-to-vigorous physical (MVPA) were analysed using factorial ANOVA. Results:<\b>
Twenty-two participants (average age 83.9 years) provided physical activity data at both time-points (exercise n=11; control n=11;). There was a significant interaction for MVPA (f1,20=5.1, p=0.036). Participants in the exercise group significantly increased their moderate-to-vigorous physical activity (minutes) from baseline (mean 7.6, SD8.0) to post-intervention (mean 11.0, SD9.0; p=0.002). There were no significant differences for sedentary or light physical activity.Discussion: Although there were only small increases in MVPA for the exercise group, these small changes may be important as a non-pharmalogical aid to improve the health and behavioural symptoms of dementia. Further studies with larger samples sizes will provide further assessment of the effects of exercise interventions in this population. External funding details Queensland health
