FIT-ATOMIC Exercise Feasibility Trial

The Exercise Training will follow a progressive interval-based training program designed for youth with MS. Participants will engage in three weekly exercise sessions. Participants will be given access to links to live virtual structured exercise sessions. The sessions will be scheduled weekly in partnership with a coach. A trained fitness instructor will lead the participants in a 10-minute warm-up, followed by 30 minutes of interval training, and a 10-minute stretching and cool down activity. Intervals will progress in intensity over the course of the 20-week program and progression will be based on individualized target heart rate zones. The session will be delivered via a live feed in order to foster social support from the participants peers enrolled in the program. Participants will have the option of completing the class in real-time and make up classes will also be available through a repository of sessions accessible through links to the repository cloud.

The Mobility and Flexibility Training will be focused on improving mobility and flexibility through three times a week stretching and mobility program. A 5-minute warm up will be followed by a series of stretches and mobility patterns that will be repeated as a circuit four times. Each session will focus on a specific muscle group - upper body, lower body or core. The classes will be led by a fitness instructor in the same manner as the exercise intervention arm with a virtual link sent to the participants.
