Their rating of the importance and likelihood towards physical activity was mainly influenced by intrinsic health (e.g., fit and healthy, losing weight, improving appearance) and social factors (e.g., having fun, spending time with friends) compared to extrinsic factors (e.g., change to win\/compete, others making fun of them). Males positively rated more extrinsic factors compared to the females, with the rating of intrinsic factors such as \u2018fit and healthy\u2019 and \u2018losing weight\u2019 stable between 14 and 17\u2009years. \u2018Appearance\u2019 was the only factor that increased in importance at 17\u2009years compared to 14\u2009years of age.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Greater awareness of the factors that young adolescents consider as important and likely for their physical activity is important.
