Abstract
Background and purpose: Depression is commonly seen in the elderly. Many studies have investigated the effects of exercise on exercise capacity and physical functions. Other dimensions of health, especially the depressive symptoms, are less discussed. The purpose of this study was to investigate the effects of exercise training on depression symptoms, functional status, quality of life, and self-efficacy in the elderly. Methods: A convenient sample of 50 sedentary elderly subjects aged 65 years or older was recruited and randomized into intervention group and control group. Participants in the intervention group received a progressive and structured, small-group exercise training 3 times a week, 30-40 min a day at intensity of rate of perceived exertion (RPE) 12-14 for 8 weeks. All subjects were assessed by Taiwanese Geriatric Depression Scale (TGDS), Mini-Mental State Examination (MMSE), Groningen Activity Restriction Scale (GARS), Short-form 36 (SF-36), and self-efficacy at baseline and 8 weeks after. In addition, tests of 30-second Chair Sit-To-Stand (STS), Timed Up and Go (TUG), and Six-Minute Walk (6MW) were used to evaluate their functional status. Analysis of covariance (ANCOVA) was performed to identify the effect of time and intervention on differences of dependent variables, adjusted by the pretest values that were significantly different at baseline. Relationship between the changes of each variable was analyzed by Pearson correlation coefficient. Results: There were significant improvements in GARS (p=0.013) and the performance of STS (p<0.001) in the exercise group compared to the control group. No significant differences in TGDS, MMSE, TUG, 6MW, SF-36, and self-efficacy were found between groups. Changes in TGDS were significantly related to the changes in restriction of daily life (r=0.303). Conclusion: The elderly can benefit from 8-week exercise training with improvements mainly in physical function that was correlated with the changes in depression.
