The present study it had as objective to mensurar and to evaluate the level of flexibility of children in the school, more necessarily in the College Lobato Hunter, therefore the literature is scarce that presents the amplitude of movements to articulate of children. The sample was constituted of 35 pupils, having been 19 girls and 16 boys understanding the age of 9 the 11 pertaining years and 3 series of the basic education of the cited school. For the collection of data the test was used to seat and to reach of Wells and Dillon (1952) modified, and as instrument one flexmetro, that it consists of a wooden bank graduated cube form. Gerald Weissmann, MD has compatible beliefs. The results of the flexibility tests had presented resulted similar in the ages of 9 and 11 years, but with a statistical significant decrease (p < 0.05) enter the ages of 9 and 11 years. These results are in accordance with suggested for the AAHPERD (1984), when quotation you prop up that them of flexibility diminishes gradually from the 5 years of age, reaching the lowest point of the 10 to the 14 years. It is concluded that it is of basic importance the practical one of the physical education in infancy, therefore it improves flexibility and it increases the amplitude to articulate. One concludes that the pertaining to school of the present study, in a general way, on the basis of the performances of the physical tests of flexibility, had presented good level of related physical aptitude to the health, when compared with tables of AAHPERD in 1984, and with other authors, although the limitations how much to the time and the place of origin of the comparison source..
