Brief summary
This is a 6 month randomized clinical trial comparing video dance, brisk walking and delayed entry controls. The interventions have two phases; a 12 week initiation phase with substantial structure and supervision, followed by a 12 week transition phase, with reduced structure and supervision. Participants are 168 overweight or obese, sedentary postmenopausal women aged 50 to 65; 60 in each exercise arm and 48 in the wait list control group. The following research questions will be assessed: 1. Is exercise adherence at 6 months better with video dance games compared to brisk walking? 2. Does video dance game exercise compared to wait list controls, induce beneficial changes in physical and mental health? 3. Does video dance game exercise compared to brisk walking better promote balance, attention and visual spatial skills, without loss of benefit to cardiovascular fitness? 4. Is video dance preferred to brisk walking for exercise among postmenopausal women? If so, who and why?
Interventions
BEHAVIORALdelayed entry control
Participants who are randomized to the delayed entry non-exercise control group receive the American Heart Association pamphlet, but no direct support for exercise implementation. After they have completed six months of follow up, they are invited to select any combination of dancing and walking that they prefer and then receive support and instruction according to the protocols described above. \--------------------------------------------------------------------------------
BEHAVIORALvideodance
Using a commercially available product called Dance Dance Revolution (DDR) this video-game based dancing system uses a game player, force sensing pad and software. The step sequences are set to a wide range of music and become more complex and frequent as the dancer gains skill. Participants are oriented over 2 weeks. For the rest of the first 3 months, the participant attends at least one supervised session per week. Participants may use the center for additional, unsupervised sessions and/or they can take a dance system home. They also receive brief behavioral intervention sessions for safety orientation, exercise education and adherence promotion. For the following 3 months, the participant enters the transition phase in which she is encouraged to continue to exercise but no formal supervision is provided.
BEHAVIORALBrisk Walking
The overall goal is to increase the duration and speed of walking, using structure and supervision for the first three months, followed by reduced support in the second three months. For the first two weeks, each participant comes to the center at least twice a week to walk.They are encouraged to gradually increase effort and duration to a target of 150 minutes per week of brisk walking.Participants are taught to use Borg's ratings of perceived exertion and self-monitored heart rate to target their level of activity. The next 10 weeks include once weekly supervised sessions and additional sessions either at the center or in preferred community settings. The recommended goal is a minimum of 150 minutes per week of exercise in sessions of at least 10 -15 minutes duration.Participants are given pedometers in order to help them monitor their progress. After 12 weeks, the participant enters a transition phase for a further 3 months.
