Elegir, de tres pruebas sugeridas, la que refleje con mayor certeza el grado de flexibilidad en el aparato locomotor

Abstract

The flexibility is a physical quality that comes from the morphologic-functional properties of the locomotive apparatus and is based on the articulation movility and the muscular elasticity. The amplitude of the joints displacement depends on the characteristics of these qualities. This work had as objective to choose, between three suggested tests, the one that reflects with greater certainty the degree of flexibility of the individuals when approaching the front part of the trunk to the thighs. The tests involve the low part of the trunk and the hip. A sample of 24 individuals between 14 and 22 years of age, 13 men and 11 women executed the three different flexibility tests. The evaluation result is the greater reach with the fingers yolks on a scale in centimeters at the moment of maximum flexion. The individuals were recorded with two camcorders capturing the frontal and the the sagital projection of the accomplishment of the tests. Three attempts in each test were performed. The best attempt and the picture of corresponding video for the two views were selected. On this images the angles between segments were measured in order to know the range of movement. The values of the measured angles and the reached lengths of the tests were related to the performance of the individuals with the purpose of knowing if a relation among them exists.
