ABSTRACT Background: Childhood and adolescence are key to the development of chronic disease stages, the distribution of fat an important factor in this regard. The aim of the study was to evaluate the effects on fat parameters of a high intensity program developed in adolescents during physical education classes. Methods: In 2013, 35 school-age children of Cáceres taken part in this study divided into two groups. The high-intensity group performed for 8 weeks, 4-6 sets of 20 seconds at maximal intensity with a ratio effort / recovery of 1: 3 to 1: 1. The other group, developed continuous aerobic exercise during the same time. It conducted an assessment of fat mass before and after the training program. Repeated measures ANOVA test was used to observe that there were no statistically significant differences. Results: Continuous aerobic training group showed statistically significant differences in intra-group analysis in the percentage of fat mass trunk (Pre: 15.66 ± 4.16 vs Post: 16.95 ± 4.03; +1, 29%; p = 0.04) and the percentage of total fat (Pre: 21.58 ± 3.93 / Post: 22.34 ± 3.70; p = 0.05). Statistically significant differences were not found in the analysis between-groups in any of the studied variables. Conclusions: The training program high intensity physical activity at school carried out during physical education classes did not improve fat mass parameters evaluated. However, maintaining these parameters could be a good result during the development of this stage, where an increase of these occurs. RESUMEN Fundamentos: La infancia y la adolescencia son etapas claves para el desarrollo de enfermedades crónicas, siendo la distribución de grasa un importante factor en este sentido. El objetivo del estudio fue evaluar los efectos sobre parámetros de grasa de un programa de alta intensidad desarrollado en adolescentes durante las clases de educación física. Métodos: Durante el año 2013, 35 escolares cacereños participaron en el estudio divididos en dos grupos. El grupo de alta intensidad realizó durante 8 semanas de 4 a 6 series de sprints de 20 segundos a máxima intensidad con una relación esfuerzo/recuperación de 1:3 a 1:1. El otro grupo desarrolló ejercicio aeróbico continuo durante el mismo tiempo. Se llevó a cabo una evaluación de la masa grasa antes y tras el programa de entrenamiento. El test ANOVA de medidas repetidas se usó para analizar si existían diferencias estadísticamente significativas entre ambos grupos. Resultados: El grupo de entren
