REACT is a randomized intervention to examine the benefits of African Dance as a method to increase physical activity behaviors in older adults. In this 6- month intervention, older African Americans will be randomly assigned to either an African Dance or an Africana Culture class. Both before and at the completion of the intervention, the investigators will collect a comprehensive neuropsychological battery and MRI scans of brain health and function to better study how physical activity influences neurocognitive health in African Americans.

---|---|---|---|---|
Other | Cardiorespiratory fitness | The investigators will conduct a sub-maximal fitness test before and after the intervention in order to calculate each participant's fitness level (via estimated V02 max). The investigators will examine group differences in fitness following the intervention. | Changes from baseline to 6-months | |
Other | Actigraphy steps per day | The investigators will collect objective physical activity levels via wrist-worn accelerometers every 6 weeks throughout the intervention. Steps per day will be a primary outcome from the actigraphy. The investigators will examine changes in physical activity over the intervention. | Changes from baseline to 6-months | |
Other | Weight | Participants will be weighed on a calibrated stadiometer both before and after the intervention. The investigators will examine percent changes in body weight in the groups before and after the intervention. | Changes from baseline to 6-months | |
Other | Loneliness | The investigators are collecting a questionnaire measuring self-perceived loneliness, the University of California Loneliness Scale (UCLALS). This is a 20-item scale in which participants rate frequency of feelings of loneliness and social isolation on a 4 point scale ranging from "never" to "often". A total score is computed which can range from 20- 80. Higher scores indicate more loneliness. The questionnaire will be assessed at baseline as well as at the 6-month followup. | Changes from baseline to 6-months | |
Other | Depression | The investigators are collecting a questionnaire measuring depressive symptoms, the Center for Epidemiologic Studies Depression Scale (CES-D). The CES-D is a 20-item measure that asks caregivers to rate how often over the past week they experienced symptoms associated with depression, such as restless sleep, poor appetite, and feeling lonely. Response options range from 0 to 3 for each item (0 = Rarely or None of the Time, 1 = Some or Little of the Time, 2 = Moderately or Much of the time, 3 = Most or Almost All the Time). Scores range from 0 to 60, with high scores indicating greater depressive symptoms. The questionnaire will be administered at baseline as well as at the 6-month followup. | Changes from baseline to 6-months | |
Other | Functional magnetic resonance imaging (fMRI) task activation | Participants will complete an N-back task while in the scanner. Task-evoked activation will be the primary outcome. The investigators will examine whether the pattern of task activation changes following the intervention. | Changes from baseline to 6-months | |
Other | resting state functional connectivity | The investigators will examine changes in resting state functional connectivity using a region-of-interest-based approach centered on the hippocampus. The investigators will examine whether the strength of connectivity (z) of the hippocampus changes following the intervention. | Changes from baseline to 6-months | |
Other | Stroop Performance | A Color-Word Stroop will be administered at baseline, and then following the intervention (6-months). The main outcome from this task is the Stroop effect (in ms). A higher Stroop effect indicates worse executive functioning. Group differences will be tested on this outcome. | Changes from baseline to 6-months | |
Primary | Flanker Performance | A Flanker task will be administered at baseline, and then following the intervention (6-months). The main outcome from this task an interference effect (in ms) which indicates how much longer it takes for a participant to make a directional response to a center arrow when the flanking arrows are arranged in congruent vs. incongruent direction from the center stimulus. A higher interference effect indicates worse executive functioning. Group differences will be tested on this outcome. | Changes from baseline to 6-months | |
Secondary | Hippocampal volume (mm3) | Structural scans will be collected at baseline as well as following the intervention. Hippocampal volume will be calculated in mm3. The investigators will examine group differences in size of the hippocampus following the intervention. | Changes from baseline to 6-months |
