The Effectiveness of Teaching the Teacher Interventions in Improving the Physical Activity among Adolescents in Schools: A Scoping Review

Abstract

Physical inactivity is a leading risk factor for global mortality as it increases the risk of non-communicable diseases and decreases overall health. Therefore, increasing physical activity (PA) is strongly recommended, particularly in adolescents. The Teaching the Teachers (TTT) approach is a prominent example of an intervention that could enhance PA levels in adolescents. However, available evidence on the efficacy of TTT interventions in promoting PA among adolescents is either limited or inconclusive. Therefore, a scoping review was conducted to provide an overview of the current state of knowledge regarding the effectiveness of TTT interventions in improving the PA of adolescent students. The PRISMA-Scoping methodology was employed, and articles in the Medline database were searched. We screened 2357 articles for inclusion, and finally included 16 articles. Most articles were conducted in European countries. The TTT interventions appeared to positively affect various aspects of PA. These aspects include support for personal autonomy, intent to engage in PA, improvements in body composition and fitness level, social support, enjoyment of Physical Education (PE), and positive attitudes towards PE. Consequently, policymakers could utilize TTT interventions to improve the physical activity of adolescents, which may reduce the burden of non-communicable diseases and foster healthier societies.
