Introduccion : Los cuestionarios de actividad fisica por lo general son los instrumentos mas sencillos y faciles de aplicar a grandes poblaciones, sin embargo, la capacidad de reproductibilidad varia entre las poblaciones. Objetivo : Analizar la fiabilidad de un cuestionario que valora la Actividad Fisica en una muestra de escolares adolescentes que viven a elevada altitud por medio de consistencia interna y test re-test. Diseno : Descriptivo-Transversal (Survey). Institucion : Universidad Nacional del Altiplano, Puno, Peru. Participantes : Adolescentes escolares de 12 a 17 anos. Intervenciones : Fueron seleccionados de forma sistematica 109 escolares de ambos sexos. Se valoro las medidas antropometricas de peso, estatura, estatura sentada y circunferencia del abdomen. Ademas se aplico un cuestionario de actividad fisica con 11 preguntas (test y re-test) con un intervalo de 7 dias. Principales medidas : Valoracion de la capacidad de reproductibilidad por consistencia interna y estabilidad. Resultados : Los valores de alpha de Cronbach (Consistencia interna) mostraron valores de 0,73 a 0,77 para ambos sexos. El Error Tecnico de Medida (ETM) fue de 0,50 a 1,61% y el coeficiente de correlacion de Spearman  oscilo entre 0,91 a 0,95. Conclusion : El cuestionario de actividad fisica muestra altos valores de confiabilidad, tanto en su consistencia interna como en la estabilidad de las medidas. Introduction: Physical activity questionnaires usually are the most simple and easy to apply to large populations, however, reproducibility capacity varies between populations. Objective: To analyze the reliability of a questionnaire to assess physical activity in a sample of school adolescents living at high altitude through internal consistency and test re-test. Design: Descriptive, transversal (Survey). Institution: Universidad Nacional del Altiplano, Puno, Peru. Participants: School Teens 12 to 17 years. Interventions: There were systematically selected 109 students of both sexes. We evaluated anthropometric measurements of weight, height, sitting height and circumference of the abdomen. In addition we applied a physical activity questionnaire with 11 questions (test and re-test) with an interval of 7 days. Main measures: capacity rating for internal consistency, reproducibility and stability. Results: Cronbach's alpha values ​​(internal consistency) showed values ​​from 0.73 to 0.77 for both sexes. Measuring technical error (SEM) was from 0.50 to 1.61% and the Spearman correlation coefficient ranges from 0.91 to 0.95. Conclusion: The physical activity questionnaire shows high values ​​of reliability, consistency both internally and in the stability of the measures.
