Dermatoglyphics And Its Relationship With The Speed Motor Capacity In Children And Adolescents

The purpose of this study was to investigate the presence of a dermatoglyphic mark characteristic of speed motor capacity in children and adolescents. A total of 1,238 female children and adolescents aged between 8 and 17 years old were surveyed. The sample was compared according to the classification parameters presented in the 20-meter-race test. The protocol for the analysis of the fingerprints was the Dermatoglyphic proposed by Cummins and Midlo, via Dermatoglyphic Fingerprint Reader®. The statistical analyzes were processed in the Statistical Package for Social Science (SPSS), version 20.0, being established the significance level p≤0,05. The comparison of the categorical variables showed a significant difference with a higher frequency of Radial Loop (LR) on the fingers MET1 (p=0,000), MET5 (0,000), MDT1 (0,000), MDT3 (0,040), and MDT5 (0,012), in the group classified as excellent and Radial Loop (LR) on the finger MDT3 (0,040), in the group classified as weak. It is concluded that there is a significant relationship between Radial Loop (LR) and the best performances in the speed test, which indicates the presence of dermatoglyphic mark that characterizes the predisposition of fetal development for different levels of speed in children and adolescents.
