Investigating Gains in Neurocognition in an Intervention Trial of Exercise
Abstract
This randomized control trial will examine whether a 12 month monitored exercise intervention improves brain health in cognitively normal older adults. This trial will also address several important unanswered questions: (1) Are the recommended public health guidelines of 150 minutes/week of exercise sufficient for improving cognitive performance? (2) Does exercise influence brain structure and/or function? (3) Is there a dose-response effect of exercise on the above variables such that greater amounts of exercise brings about greater benefits in cognitive and brain health? (4) What are the mechanisms by which exercise influences brain health? and (5) What factors attenuate or magnify the effects of exercise on brain and cognitive health and contribute to the individual variability in intervention outcomes?
Conditions: Healthy, Cognitive Function 1, Social.
Primary outcome: Change in Cognitive Function.
Enrollment: 648 participants.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 648 participants or records.
