Evaluation of Applications for Mobile Devices on the Practice of Physical Exercise in Adolescents

The use of mobile devices has changed the way we relate to each other, influencing teaching–learning processes and the motivation of adolescents towards these processes. One of the most developed tools has been applications (apps), which are software used on cell phones, tablets or computers. Hence, the aim of this study is to analyze the content of applications for mobile devices that is considered the most suitable complement to Physical Education (PE) classes for secondary school students. A retrospective descriptive study was carried out, collecting information on the main characteristics of 31 free fitness apps: the descriptive, technical, educational and psychological dimensions. The results of this study show that most of the apps for physical activity have recent updates and are mainly related to cardiovascular exercise or strength for two purposes: either for exercise accounting or the creation of training plans for the user. They are intended for users of very heterogeneous ages and, therefore, do not take into account their individual characteristics. They do not have an adequate design to facilitate their didactic use. Therefore, we conclude that the applications evaluated lack the necessary educational potential to be used in the PE classroom. Based on the content analysis carried out, we describe a series of criteria that allow teachers and adolescents themselves to select physical exercise apps, and we propose to carry out research to guide developers when developing digital training/physical exercise content with an educational component that can be used as a complement for adolescents in- and outside the field of PE.
