Fit & Active Seniors Trial (FAST)

21. února 2017 aktualizováno: Edward McAuley, University of Illinois at Urbana-Champaign

Influence of Fitness on Brain and Cognition II

The investigators propose to test the hypothesis that a six-month intervention of combined fitness and cognitive training in the form of dancing will have a significant positive effect on a variety of executive control and memory processes as well as brain structure and function as compared to a non-aerobic strength and balance control/comparison group. Additionally, these two groups will be compared to walking groups in which one of the walking groups will also be provided with a daily, liquid, milk-based nutritional supplement.

Detailní popis

Our previous trial (known as HALT, Healthy Active Lifestyle Trial) suggests that improvements in aerobic fitness have beneficial effects on cognitive function that are rather specific. That is, improvements in aerobic fitness appear to result in improvements in executive control processes such as scheduling, planning, coordination, inhibition, and working memory - some of the very cognitive abilities most affected during aging. Indeed, executive control processes and the prefrontal and frontal regions which support them have shown substantial and disproportionate age-related declines. The main hypothesis that the investigators test in the present project is that such deficits may be particularly benefited by improvements in aerobic fitness combined with cognitive training in the form of dance. Additionally, we will compare the outcomes of these interventions with an aerobic condition (walking) group and an aerobic condition (walking) group that also is provided with a daily nutritional supplement (walking + nutrition). The investigators will examine the relationship between aerobic fitness, physical activity, cognitive status, and brain function with this six-month aerobic training intervention study. The investigators will collect psychosocial data and functional fitness data to assess other relevant changes in psychological and physical function brought about by exercise training. Healthy, non-active older adults (60 to 79 years of age) will be recruited from the local community. Half One quarter of the older adults will be randomly assigned to an aerobic/cognitive combination group (dance), one quarter will be while the remaining half of the older adults will be randomly assigned to a non-aerobic control group (stretching, strengthening, and stability), one quarter will be assigned to the walking group, and one quarter will be assigned to the walking + nutrition group. The exercise interventions will be conducted by trained exercise staff. The participants will be assessed before and after the intervention (6 months). Assessments will include (a) cardiorespiratory testing, (b) physical activity monitoring (c) performance on neurocognitive tests of executive and non-executive function (d) measures of brain activation (fMRI) during cognitive tasks in a 3.0 tesla MRI system (e) a battery of psychosocial questionnaires (f) functional performance measures and (g) a mock street walking task.
