Male adolescents' reasons for participating in physical activity, barriers to participation, and suggestions for increasing participation.

This study explored male adolescents' reasons for participating in moderate and vigorous physical activity, perceived barriers to moderate and vigorous physical activity, and suggestions as to what can be done to increase participation in physical activity. A total of 26 male 15- and 16-year-old adolescents participated in focus group sessions, which were audiotaped and transcribed verbatim; qualitative software facilitated data analysis. A constant comparison approach was used to inductively develop themes. It was found that participants engaged in physical activity for both intrinsic and extrinsic reasons. Their perceived barriers to physical activity included both internal factors (individual characteristics, lower priority for physical activity, and involvement in technology-related activities) and external factors (the influence of peers and family, lack of time, and inaccessibility and cost of facilities). Participants suggested that physical activity be promoted more in the community and that an environment more supportive of physical activity be developed. Results suggest that a variety of strategies should be used to help male adolescents maintain or increase participation in moderate and vigorous physical activity.
