Abstract
- Objectives To investigate the effects of multimodal supervised exercise on physical functioning, falls, and related injuries in older women. Design Two-year randomized controlled trial. Setting Tampere, Finland. Participants Women aged 70 to 80 who had fallen in the previous year (n = 409). Intervention Participants were randomly assigned to an exercise or control group ( NCT00986466). Exercisers participated in group exercise classes twice a week for 12 months and once a week for the subsequent 12 months and home exercises. Controls maintained their current physical activity. Measurements Physical functioning assessed at baseline and at 6-month intervals during the intervention. Falls and related injuries monitored with fall diaries. Results Intention-to-treat analyses showed that exercise led to significant improvements in physical functioning. Leg strength differed significantly between the groups (mean change: 14.1%, 95% confidence interval (CI) = 8.0 to 20.2 in exercisers; 1.6%, 95% CI = −4.5 to 7.7 in controls; P < .001). Chair stand time also differed significantly between groups (7.4%, 95% CI 3.8 to 10.8% in exercisers; 2.4%, 95% CI = −1.6 to 6.2) in controls; P = .02). Between-group differences were significant for fast walking speed ( P = .003) and probability of completing the backward walking test ( P < .001), favoring exercisers. Timed Up-and-Go and grip strength did not differ between groups. There was no difference in the total falls incidence rate ratio (IRR = 1.0, 95% CI = 0.79 to 1.26), but exercisers were less likely to have medically attended injurious falls (IRR = 0.45, 95% CI = 0.27 to 0.78; P = .004). Conclusion Twenty-four months of multimodal exercise enhanced physical functioning in women aged 70 to 80 with a history of falls. Although the total number of falls was not lower than in controls, the rate of medically attended injurious falls was more than 50% lower. [ABSTRACT FROM AUTHOR]
