The study received the approval of the University of Kristianstad ethical committee. Fifty-two percent of the girls exercised regularly, no significant differences were found between theoretical and practical programs. Many of the girls exercised together.

The girls’ exercise habits were influenced both positively and negatively due to supportive environments. The supportive environments were: family, friends and school.
