Abstract
Introducción: El propósito del presente estudio es analizar el modelo teórico, agentes, estrategias, duración, escenarios de implementación, grado escolar e indicadores de resultados, utilizados en los programas de promoción de la actividad física en el contexto escolar desarrollados en el ámbito internacional en los últimos veinticinco años. Método: Se realizó una revisión de los diferentes estudios que desarrollaron programas de actividad física encaminada a la salud en el contexto escolar. Se utilizaron y combinaron diversas estrategias de búsqueda, manuales y electrónicas. Resultados: Siete estudios utilizaron modelos teóricos para el diseño de los programas. Los principales agentes involucrados en la implementación de los programas fueron los docentes de educación física (EF), y los estudiantes. El escenario para la implementación se ubicó básicamente en la clase de educación física. Las estrategias estaban dirigidas principalmente a modificar el currículo de las clases de EF. Las intervenciones se orientaron fundamentalmente a niños de escuela elemental. La duración variaba entre 1 y 12 meses. Los indicadores utilizados para verificar el impacto del programa fueron: incremento en la cantidad de AF, IMC, y peso corporal. La mayor parte de estos estudios se llevó a cabo en escuelas de Estados Unidos, Canadá, India, Reino Unido e Irán. Conclusiones: A pesar de los resultados positivos obtenidos en cada una de las intervenciones, se identificó heterogeneidad: en la metodología, población, actores involucrados e indicadores de eficacia, lo cual no permite realizar comparaciones entre los diferentes estudios.

Method: It was made a review of different studies that developed physical activity programs aimed to health on school context. Were used and combined diverse search strategies, manual and electronic. Results: Seven studies used theoretical models for the design of programs. The main agents involved in the implementation of programs were the teachers of physical education (PE), and students. The space for implementation was located mainly in the physical education class. Strategies were directed to modify the curriculum of the physical education classes. Interventions were focused on children of elementary school. The duration ranged between 1 and 12 months. The indicators used to confirm the impact of the program were: increased in the amount of PA, BMI and body weight. Most of the studies were conducted in schools at United States, Canada, India, United Kingdom and Iran. Conclusions: Despite the positive results obtained in each of the interventions, heterogeneity was identified in: the methodology, population, involved actors and performance indicators, which does not allow comparisons between the different studies.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
