Measure
Phase 1
Will collect in-depth gait assessments under single and dual task conditions. This is a non-interventional group, with all outcomes collected during a single visit.
Phase 2: Dual Task
This group will complete an exercise intervention that involves performing dual tasking activities (simultaneously performing 2 things at once). This group will exercise 3x/wk for 8 weeks.
Phase 2: Single Task
This group will complete an exercise intervention that involves performing single task activities. The participant will perform motor tasks and cognitive tasks individually. This group will exercise 3x/wk for 8 weeks.
