Summary

The objectives of this study are to determine the feasibility and potential efficacy of remotely delivered group exercise sessions to increase daily moderate to vigorous physical activity in adults with Down syndrome, relative to a usual care control. Participants will be randomized to attend 40 min remotely delivered group moderate to vigorous physical activity (MVPA) sessions at low frequency (1 session/wk.,RL), high frequency (3 sessions/wk., RH), or usual care control usual care control (UC). In addition to the group MVPA sessions, participants in both the RL and RH groups will also receive a step counter, access to resources for increasing MVPA, and one 20-min remotely delivered individual support/education session/wk. Content for both the RL and RH arms will be identical with the exception of group session frequency (1 vs. 3/wk.). Participants in the UC arm will receive a step counter, access to resources for increasing MVPA, and monthly remote individual support/education).The primary aim is to Assess daily MVPA (min) in the RL, RH, and UC arms at baseline, 3, 6, 9, and 12 mos., and obtain effect sizes for change in MVPA over 12-mos.Secondary Aim 1 is to assess the impact of MVPA on cardiovascular fitness, quality of life, cognitive function, and brain parameters related to Alzheimer's Disease (whole and regional brain volume, functional connectivity, and cerebral blood flow) at baseline, 6, and 12 mos. Secondary Aim 2 will determine the feasibility (retention, session attendance, use of recorded sessions (RH/RL only) of RL, RH, and UC interventions.
