Speciality of Kinesiology CORRELATIONS OF STRUCTURAL AND FUNCTIONAL PARAMETERS FOR HEALTHY AND MENTAL DEFECTIVE CHILDREN Author: Lorita Kulakauskienė. Supervisor: Prof., Habil. Dr. Alfonsas Vainoras. The work has been carried out at: Kaunas University of Medicine, Faculty of Public Health, Department of Kinesiology and Sport medicine, 2003-2005. The aim of the study: to determine correlations of structural and functional parameters for healthy and mental defective children. Objectives: 1. To compare groups of healthy and mental defective children together by means of measured structural and functional parameters. 2. To size up essential correlations of structural and functional parameters. 3. To examine possible reasons of different correlations between two groups of investigative children. 4. To look into organism, as a complex system, features in both groups of investigative children. The object of the study: two groups of children. One of them – 22 mental defective children (mean age – 14,9 years), and the other – 22 healthy children (mean age – 15,04 years). Methods of the study: anthropometry, measuring arterial blood pressure, cirthometry, skoliometry, electrocardiography and mathematical statistics methods. Results: Means of arterial blood pressure and electrocardiographical parameter aQRS were statistically significantly (p<0,05) more in healthy children group (S), but means of cirthometry parameter C_K and skoliometry parameter Sk_3 - in mental defective children group (PA). Height, weight and heart rate were less in PA group. Electrocardiographical interval QT had statistically significant correlations with height, weight and others electrocardiographical intervals Pd, PQ, QRSd in PA group. Conslusions: 1. Means of arterial blood pressure, electrocardiographical parameter aQRS, cirthometry parameter C_K and skoliometry parameter Sk_3 had statistically significant differences in investigative groups. 2. Electrocardiographical interval QT had statistically significant correlations with height, weight and others electrocardiographical intervals Pd, PQ, QRSd in PA group. 3. Electrocardiographical intervals Pd, QT, QTc were more in PA group, but heart rate was less. That can point influense of enlarged suppression in PA group. 4. Correlations of measured parameters in two investigative groups show tight connections between all systems of organism.
