Summary

The purpose of this research study is to help scientists and health care providers learn more about preventing dementia and brain disease in older adults. There is an urgent need to develop strategies to prevent or slow down memory loss and brain function decline in the elderly. In this study, the investigators hope to learn how physical exercise and a brain training program work together to improve thinking and memory in older adults. Specifically, these aims include: * Learning whether physical activities (like biking or treadmill walking or Wii Fit games) will help improve the benefits of a brain training program. Based on preliminary results and that in the literature, the investigators anticipate greater cognitive benefits in the Exercise + Cognitive training groups than the Cognitive Training alone group. * To determine whether the benefits of adding exercise will occur quickly or develop more gradually over time. The investigators suspect that a major benefit of exercise pre-dosing will occur by the 12th week of the program. * To examine whether Wii-Fit exercise games cause similar effects on brain training as traditional exercise programs such as biking or walking. Although several recent studies have raised questions about the true aerobic benefit of exergames such as Wii-Fit Plus, other evidence suggests that these weaker aerobic benefits may be offset by the greater novelty and interest level afforded by exergames.

Detailed description

Research Participants take part in a 16 week Wellness Program, which includes either traditional physical exercise with brain training(Group A), Wii exergaming with brain training(Group B) or brain training alone (Group C). Participants are randomly assigned to groups. A comprehensive battery of neuropsychological tests, surveys and assessments are given prior to start of the intervention, at completion of the 16 weeks, and again 3 months post completion. The program involves 4 days of physical activity each week for groups A \& B. The physical exercise/activity portion will involve warm up stretching and then either Group A-traditional exercise (like riding a stationary recumbent bicycle or walking on a treadmill), Group B- playing Nintendo Wii Exergames with a television based video game, or Group C- NO exercise at all. Every 4th week the 16 week intervention period, all participants in all three groups will also complete 80 minutes of brain training activities each day of the week. This is in addition to the previously assigned physical activity for Groups A \& B. The brain training regimen consists of Posit Science Insight computer based brain games. The Insight program consists of five different modules that focus on visual processing, attention, and memory. Each of the modules are described below: 1. Bird Safari: This module involves identifying and ordering simple visual stimuli that flash on a screen. The goal is to improve ability to respond quickly to visual stimuli and to segment rapidly changing visual pictures. 2. Jewel Diver: This module involves tracking objects as they become hidden by distractors. The goal is to improve ability of visual system to rapidly identify and discriminate objects in the visual periphery. 3. Master Gardener: This module involves visual working memory and matching pairs of pictures. 4. Road Tour: This is a simulated driving exercise that involves divided attention to oncoming cars and road signs. The goal is to improve ability of visual system to continuously track multiple objects against a field of distractors. 5. Sweep Seeker: In this exercise, participants identify complex moving visual stimuli. The goal is to improve rapid, sequential eye movements to salient visual targets, process relevant information and then make rapid decisions to identify, discriminate and classify targets. Questionnaires regarding the participants mood before and after the brain training weekly are administered. In addition, brief questionnaires on attention and memory are given to measure thinking and memory progress.

Interventions

Type	Name	Description
BEHAVIORAL	Exercise	Participants will do physical activity that raises heart rate to a target heart rate (THR)zone which is pre-calculated using the Karvonen Formula: (THR={(max. heart rate- rest heart rate) x %intensity} + resting heart rate Participants begin exercise regimen starting at 50% THR for intensity and gradually increase by 5% up to a maximum of 75% THR. Activity duration begins at 10 mins./day and increases 5 mins. every week following to a maximum of 40 mins. Polar Heart Rate monitors are used to measure THR and save resulting data.
BEHAVIORAL	Exergames	Participants experience Wii Video Games in a standardized format, beginning with 15 mins of seated play per day on week one, and then increasing 5 mins./week on each week following up to a maximum of 40mins. of play. Participants are made aware of the Target Heart Rate Zone for the week, but are not required to reach that zone during play. The THR is calculated by the Karvonen Formula: THR={(max. heart rate- rest heart rate) x %intensity} + resting heart rate Polar Heart Rate monitors are used to measure THR and save resulting data.
BEHAVIORAL	Cognitive Training	Posit Science INSIGHT program games are used for all cognitive training. Participants are exposed to (2) forty minute game sessions per day, for the cognitive training weeks #4,8,12,16. INSIGHT Assessments are done at baseline, the start of each training week and at week 28.
