Movement Disorders Clinical Trials

Experimental: Forced Exercise (FE)

Participants in the forced exercise group will complete an eight-week control period where they will be asked to maintain their usual activities and wear an activity monitoring device. This will be followed by an eight-week cycling program using a stationary bike equipped with a motor that assists pedaling. The motor helps maintain a cadence higher than the participant's voluntary pace, typically around 80-90 revolutions per minute, while the participant continues to actively pedal. Each session lasts about 40 minutes and occurs three times per week under supervision of an exercise professional. Heart rate will be monitored to ensure safety and maintain aerobic intensity. The goal is to provide consistent, high-rate cycling that participants likely could not achieve on their own.

Experimental: Voluntary Exercise (VE)

Participants in the voluntary exercise group will complete an eight-week control period where they will be asked to maintain their usual activities and wear an activity monitoring device. This will be followed by an eight-week cycling program on a standard stationary bike. They will cycle at a self-selected pace while maintaining a target heart rate to ensure aerobic intensity. Each session lasts about 40 minutes and occurs three times per week under supervision of an exercise professional. Heart rate will be monitored for safety and consistency.
