Clinical Trial Summary

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.

Description:

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.

Intervention

Behavioral:
• Dance Group
Participants will be instructed and learn various forms of dance (i.e. English country, folk, ballroom) and will be led by trained dance instructors and exercise specialists. Participants will for one-hour sessions and meet three times per week for six months.
• Strength, Stretching, Stability
Exercises focusing on strength, flexibility and balance will be performed at one-hour sessions held three times per week for six months. Classes are led by trained exercise specialists.
• Walking
Participants in this moderate aerobic conditioning exercise program will be instructed in a walking program that focuses on having them walk within their target heart rate. They will be provided with heart rate monitors and pedometers for accurate record keeping. They will meet three times per week for one hour for six months. Warm up and cool down stretches will be a part of each walking session and sessions will be monitored and led by trained exercise specialists.
• Walking + Nutrition
Participants in this moderate aerobic conditioning exercise program will be instructed in a walking program that focuses on having them walk within their target heart rate. They will be provided with heart rate monitors and pedometers for accurate record keeping. They will meet three times per week for one hour for six months. Warm up and cool down stretches will be a part of each walking session and sessions will be monitored and led by trained exercise specialists. These participants will also be provided with a daily nutritionally balanced liquid, milk-based supplement formula.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline to month six in brain structure and function	Participants will undergo a neuropsychological battery of tasks assessing memory, attention and decision-making at baseline and month six. They will also undergo an fMRI during which images of brain structure and function (completing tasks during image collection) will be compared from baseline to month six.	Baseline and six months
Primary	Change from baseline to month six in cardiorespiratory fitness	We will conduct graded maximal exercise treadmill test measuring peak oxygen consumption at baseline and six months.	Baseline and six months
Secondary	Change from baseline to month six: Quality of life	We will assess multiple indicators of Quality of Life such as: depression; physical and mental health status; satisfaction with life; etc.	Baseline and six months
Secondary	Change from baseline to month six: Self-efficacy	We will examine the extent to which self-efficacy (e.g. barriers, adherence, function) changes as a function of participation in regular group physical activity training.	Baseline, three weeks and six months
Secondary	Program adherence over six month intervention	We will monitor attendance during the six-month intervention(program meets three days per week).	Six months
Secondary	Change from baseline to month six: Physical function	We will conduct functional fitness testing including tests of balance, strength, mobility and flexibility at baseline and six months.	Baseline and six months
Secondary	Change from baseline to month six: Psychosocial Outcomes	We will assess changes in psychosocial function (e.g. self-esteem; social support; anxiety) by written questionnaires.	Baseline and six months
