Effects of 10 Weeks of Walking With Mobile Step-Tracking Apps on Body Composition, Fitness, and Psychological State in Adolescents Who Are Overweight and Obese: Randomized Controlled Trial.

Background: In recent decades, physical activity intervention programs have been developed to reduce overweight and obesity in adolescents. However, this population is considered hard to reach in physical activity programs due to lack of adherence and poor results. Interventions with mobile phones in the adolescent population with normal weight have shown benefits, so this line of research may provide benefits in adolescents with overweight or obesity, although it has not yet been explored in the scientific literature.

Assessment of Step Tracker Mobile Applications for the Promotion of Physical Activity by Adolescents Based on Their Weight Status.

The objectives of the present study were to analyze the adherence of normal weight and overweight/obese adolescents to intervention with mobile applications; to establish the differences in the evaluation of the mobile application and in the problematic use of the mobile phone between normal weight and overweight/obese adolescents; and to determine the relationship between the distance travelled, the evaluation of the mobile applications, and the conflictive use of the mobile phone. A quasi-experimental design was carried out with the participation of 70 adolescents between 12 and 16 years old (mean age: 14.25 ± 1.

Gender equity in sport from the perspective of European women athletes and sport managers, physical education teachers and sport coaches.

Introduction: For years, gender inequality has conditioned women's participation in sport, exposing them to difficult situations and numerous barriers to face. However, no previous research has analyzed the situation of women in sport from the perspective of the athletes themselves, or from the perspective of the coaches, teachers or managers who work with them.

Methods: This study examines the perspectives of European women athletes, sports managers, physical education teachers, and sports coaches, on gender equity in sports across six European countries: Greece, Ireland, Italy, Portugal, Spain, and Turkey.
