body composition, skinfold Method, accuracy of measurements, coefficient of cirrelation, standard error of estimate

The aim of this study is to verify the external criterion validity of measuring body composition by skinfold method and to compare the obtained results with the results gained using the DEXA method. The investigated group consisted of 74 individuals (45 males and 29 females) whose average age was 20.2 ? 0.90 and 19.5 ? 0.73 respectively. The DEXA and skinfold methods and methodologies according to Pařízková, Matiegka, Drinkwater and Ross were applied to measure body composition. The acquired values of the Pearson correlation were r = 0.781 (females - according to Pařízková) and r = 0.815 (females - according to Matiegka), r = 0.678 (females - according to Drinkwater and Ross) and r = 0.876 (males - according to Pařízková), r = 0.921 (males - according to Matiegka),r = 0.765 (males - according to Drinkwater and Ross) . Standard error of estimate dmax = ? 2 sy/x was found to be ? 3.54 to 4.50% for females, and ? 2.88 to 4.86% for males.
