We are looking for high school girls who have not participated in organized sport (sport with a coach or teacher present outside of typical school curriculum [not gym class]) in the last year and are not planning on participating in organized sport in the next year. Participants must be able to walk, run, and jump/hop on one leg. They must also have access to a phone or email to receive and complete weekly electronic surveys.
