title: Iranian adolescents' insufficient physical activity: a mixed methods explanatory sequential study.
abstract: BACKGROUND
  Adolescents' physical activity decreases from the stage of childhood to adulthood. This study was addressed to explain adolescents' insufficient physical activity (IPA) and its related factors. The subjects were 1201 adolescents in the quantitative phase and 25 adolescents in the quantitative phase.
  
  
  METHODS
  An explanatory sequential mixed methods design with follow-up explanations variant was used, which involved collecting quantitative data (1201 adolescents) first and then explaining the quantitative results with in-depth interviews and written narrative (25 adolescents) during a qualitative study.
  
  
  RESULTS
  The quantitative results showed that 98.8% of adolescents did not have the recommended physical activity. Five themes were extracted in the qualitative phase including the inhibitory effect of the school environment and peers, as well as the inhibitory effect of the family environment, lack of availability and cultural barriers for the presence of girls in the community, the effect of self-feeling and self-understanding, and physical and mental exhaustion and permutation. According to the qualitative findings of the study, physical and mental exhaustion expressed the fact that, although adolescents had an unfavorable sense of IPA, they were under the effects of the intrinsic and extrinsic factors.
  
  
  CONCLUSIONS
  The comparison of these themes indicates that this behavior is imposable but not optional.
