Overweight adolescents’ views on physical activity – experiences of participants in an internet-based intervention: a qualitative study

Background Overweight and obese adolescents are reported to be less physically active than their peers. Research-based knowledge about their views may contribute to a better understanding of key factors that may foster or undermine motivation for physical activity, and provide knowledge for the future development of interventions. This paper explores experiences of physical activity among overweight adolescents, age 13-14 years, participants in Young & Active, a web-based controlled trial intervention to increase physical activity (ClinicalTrials.gov NCT01700309). The theoretical perspective is based on Self-Determination Theory.
