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.


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.


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.


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.
