Recruitment status

COMPLETED

Study phase

Participant Flow

Volunteers were recruited from students, faculty, and staff at the University of Wisconsin - Madison to participate in this study.

Volunteer eligibility was determined through a preliminary phone screen, participants were randomly assigned to receive the experimental task (Yoga) or the control task (quiet rest) first. Participants will then cross over 2-5 days after their first task to act as their own controls.
