Introduction: Technological evolutions in the modern world have caused significant changes in the way children and adolescents perform their amusements and leisure, leading to a reduction in the level of physical activity and impairing the formation of healthy habits. There is evidence that the level of physical fitness of children and adolescents has declined over time. In this sense studies that verify the secular trend of growth and physical fitness gain importance. Objective: to analyze, through a secular tendency, changes occurred in parameters of physical fitness related to health in schoolchildren from 7 to 12 years of age in the city of Taguatinga- DF, from 1992 to 2015. Materials and Methods: The study addresses With a sample of 2,281students (1,114 males and 1,167 females), from 2001 to 2005 (years 2000) with 774 students (348 boys and 426 girls) and Year of 2015 with 370 students (187 boys and 183 girls), totaling 3,425 students (1649 boys and 1,776 girls). Body mass and height were obtained, which gave rise to the body mass index, tricipital and subscapular skinfolds, with which the percentage of fat was calculated, in addition to agility, flexibility, lower limb strength and sexual maturation. Means, deviations and frequency were analyzed. Normality was verified with Shapiro Wilks and Kolmogorov-Smirnov. In addition to the analysis of variance in case of normality and Kruskal Wallis where there was no normality. The study was approved by the Ethics Committee of the Catholic University of Brasilia under number 1,086,406. Results: Body mass, height, body mass index and fat percentage of boys and girls presented significant differences when we compared the three moments of the study. These variables showed a positive secular trend, mainly when we compare the years 1990 and the year 2015. The results also show that when compared with reference tables for ages and sex the majority are classified in unsatisfactory levels. The variables flexibility and horizontal jump presented a seculartendency negative, demonstrating a worsening of results over time. There was also worsening in the variable agility that presented a positive secular tendency. It was found that the boys in the sample are initiating the process of sexual maturation earlier than the girls. The boys presented better performance in all stages of sexual maturation, except for the variable flexibility, where the girls were better. Conclusions: In a qualitative analysis, the results of the secular trend of both physical growth and motor performance of boys and girls presented worse results when we compared the first moment of the study (1990s) with the present moment (2015). It is suggested a great attention to the objectives of the Physical Education classes at the Public School and a pedagogical supervision to the teachers who teach this discipline.
