Topic: Risk, prevention and care in population studies
Objective We evaluated the effects of exercise on neurobehavioral function in healthy older people more than 75 years of age. Design A randomized controlled trial with 6-month follow-up was conducted. Setting The study was performed in the rural town of Kahoku, Japan, the population of which is considered representative of the older population of Japan. Participants We studied 42 healthy volunteers (18 men and 24 women; mean age, 79 years (range 75 to 87 years)) who were randomly assigned to one of two groups, exercise or control. Intervention Subjects assigned to the exercise group were instructed to exercise for 60 minutes twice a week for 6 months. Subjects in the control group were not instructed to engage in an specific exercise regimen. Measurements The following measurements were recorded for both groups at baseline and at 6-month follow-up: (1) Neurobehavioral function as determined by the following tests: Mini-Mental State Exam (MMSE), Hasegawa Dementia Scale Revised (HDSR), Visuospatial Cognitive Performance Test (VCP-test), Button score, Up & Go test, and Functional Reach; and (2) Body mass index and blood pressure. Results The effects of exercise were shown in the Up & Go test, and Functional Reach (ANOVA with repeated measures). Conclusion This study demonstrates the acceptability and effectiveness of exercise on neurobehavioral function, even in older people more than 75 years of age.
Key findings
- Results The effects of exercise were shown in the Up & Go test, and Functional Reach (ANOVA with repeated measures).
Why it matters
In this small randomized trial of 42 healthy volunteers over age 75, exercise showed effects on the Up & Go test and Functional Reach. The study did not report effects on the cognitive test measures, so it does not show that exercise improves cognition or prevents dementia.
