Behavioral: Remote Low
Participants will attend 40 min remotely delivered group MVPA sessions once a week, receive a step counter, access to resources for increasing MVPA, and one 20-min remotely delivered individual support/education session/wk.
Behavioral: Remote High
Participants will attend 40 min remotely delivered group MVPA sessions 3x a week, receive a step counter, access to resources for increasing MVPA, and one 20-min remotely delivered individual support/education session/wk.
Behavioral: Personal Coach
Participants will receive a step counter, access to resources for increasing MVPA, and monthly remote individual support/education.
- Moderate to Vigorous Physical Activity (MVPA) [ Time Frame: Baseline to 12 months ]MVPA will be assessed at baseline (month 0), 3, 6, 9, and, 12 months, using an ActiGraph tri-axial accelerometer
- Cognitive Function [ Time Frame: Baseline to 12 months ]Working memory, processing speed, multitasking, and episodic memory will be assessed at baseline, 6 and, and 12 months, using tests selected from the widely used Cambridge Neuropsychological Test Automated Battery (CANTAB, Cambridge Cognition, LTD, Cambridge, UK) for Down syndrome. The CANTAB for Down syndrome uses a battery of tests including multitasking, episodic memory, executive function and processing speed.
- Cardiovascular fitness [ Time Frame: Baseline to 12 months ]Maximal treadmill tests (modified Balke protocol) will be completed at baseline, 6, and 12 months
- Change in Quality of Life [ Time Frame: Baseline to 12 months ]Quality of life will be assessed at baseline, 6, and 12 months with the Personal Well-Being Index Intellectual Disability, which contains 7 items, each corresponding to a quality of life domain: standard of living, health, life achievement, personal relationships, personal safety, community connectedness, and future security. Participants answer questions on a 0-4 scale, with 0 being least happy and 4 being most happy.
- Brain volume [ Time Frame: Baseline to 12 months ]Brain volume will be measured using structural MRI at baseline, 6, and 12 months
- Functional connectivity [ Time Frame: Baseline to 12 months ]Functional connectivity will be measured using resting state MRI (rsMRI) at baseline, 6, and 12 months.
- Cerebral blood flow [ Time Frame: Baseline to 12 months ]Functional connectivity will be measured using arterial spin labeling at baseline, 6, and 12 months
- Retention [ Time Frame: Baseline to 12 months ]Retention will be measured by the percentage of participants who complete the 12 month intervention, defined as completing the 12 month outcome assessments.
- Session attendance [ Time Frame: Baseline to 12 months ]Session attendance for both group MVPA and education/support sessions from baseline to 12 months will be obtained from records maintained by the health educator, and expressed as the percent of possible sessions. Attendance at group MVPA sessions will be defined as being logged in to the video conference and remaining on the screen for the entire 30-min session. Attendance at individual support/education sessions, for the both exercise and UC conditions, will be defined as answering the FaceTime call, and being present on screen for the entire session.
- Use of recorded exercise sessions [ Time Frame: Baseline to 12 months ]Use of recorded exercise sessions will be tracked using Dropbox which provides information on how many times each user watched a video.
- Reported Serious adverse event [ Time Frame: Baseline to 12 months ]Safety will be measured by number of participants reporting a serious adverse event, i.e., any untoward medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or results in persistent or significant disability/incapacity.
- Weight [ Time Frame: Baseline to 12 months ]Weight will be measured in light clothing on a calibrated scale (Model #PS6600, Belfour, Saukville, WI) to the nearest 0.1 kg.
- Height [ Time Frame: Baseline to 12 months ]Standing height will be measured with a portable stadiometer (Model #IP0955, Invicta Plastics Limited, Leicester, UK).
- Waist Circumference [ Time Frame: Baseline to 12 months ]Waist circumference will be assessed using a waist tape measure.
