Summary: 
      The use of mobile applications to promote the practice of physical activity has begun to be
      used in the adolescent population in recent years. This has made it possible to carry out
      interventions inside and outside the educational setting, the latter being the ones that have
      brought the greatest benefits. Thus, it has been observed that the promotion of the use of
      mobile applications in out-of-school hours from the subject of physical education has
      reported significant benefits on body composition and fitness in the adolescent population.
      However, there is no known research that has analyzed whether the effect achieved with mobile
      applications when their use is mandatory disappears when they are no longer promoted from the
      physical education subject. Therefore, this project goes further and tries to find out
      whether after the ten-week period of mandatory use of the applications, adolescents continue
      to use the applications autonomously and the beneficial effects achieved are maintained or
      disappear due to the lack of use.

      For this purpose, a 10-week intervention was planned in which the adolescents used the mobile
      applications. Prior to the start of the intervention, the adolescents' body composition and
      fitness (pre) were measured. At the end of the intervention of mandatory use of the mobile
      applications, the adolescents were measured again (post). And after the post measurement, the
      adolescents were left for 10 weeks during which they could use the applications autonomously.
      A third measurement of the adolescents was performed after this 10-week period (post 2).

      The aim of this project was to find out the effects of stopping the use of the mobile fitness
      apps on body composition and fitness of the adolescents.
    


Intervention name(s): The use of mobile applications promoted from the physical education classroom to improve adolescent health.
Intervention type(s): Behavioral
Intervention description(s): Before starting the intervention, a total of 465 adolescents participated in pretest measurements (T1).
Researchers in charge of explaining how the apps worked were not involved in the measurements or subsequent analysis, as they knew which student belonged to each App and control group. Once each app had been described and its use explained, a training plan was drawn up to be followed during the period of mandatory use.
The adolescents were motivated to utilize the app for a duration of ten weeks, aiming for a minimum usage of three times per week.
After the mandatory intervention with the mobile apps, post-test measurements were carried out (T2). Then, a period of 10 weeks was provided in which the use of the app was neither mandatory nor promoted from the physical education subject, after which the post-test 2 measurements (T3) were taken.
