    Se pretende conocer si existen cambios en la cantidad de grasa corporal de los adolescentes durante el tiempo escolar y no escolar. Participaron 145 adolescentes de educación secundaria. El 54,5% fueron varones y el resto mujeres, con un peso medio de 59,67 ± 13,46 kg. y 60,53 ± 12,64 kg. respectivamente. Se realizaron medidas de bioimpedancia eléctrica en tres momentos diferentes (junio-septiembre-diciembre), utilizando para la obtención de resultados finales la ecuación de ajuste de Deurenberg et al. (1991). La variabilidad de grasa corporal fue tratada con análisis de varianza (ANOVA). Se encontró que existen diferencias estadísticamente significativas en la cantidad de grasa corporal de los participantes entre junio y septiembre, y junio y diciembre (p<0.001) pero no entre septiembre y diciembre, con un aumento del 4,72% durante el periodo vacacional, y de sólo un 0,41% durante el periodo escolar.

    This paper study objectives are the changes at the body fat of teenagers between the teaching and non-teaching period. 145 teenagers of two public high schools taken part in the research. 54.5% male his weight was 13.89 ± 0.80, and the female weight was 60.53 ± 12.64 kg. Measurements of the electrical bio impedance were made at three different dates at June, September and December of 2007. The results were obtained with Deurenberg et al.�s (1991) equation. Variance analysis (ANOVA) was used for body fat variability. Statistically significant differences in the sample�s body fat were found to exist between June and September, and June and December (p<0.001), but not between September and December, with a body fat increase of 4.72% during the non-teaching period and 0.41% during the teaching period.
