VALIDITY OF BODY DENSITY WITH METHODS OF BODY MASS INDEX, SKIN FOLD, BIO- ELECTRICAL IMPEDANCE & CRITERION METHOD OF HYDROSTATIC IN MEN ATHLETES OF SWIMMING

The goal of present research is estimating and validity of body density with methods of Body Mass Index, Skin Fold, Bio-Electrical Impedance and Criterion Method of Hydrostatic in men athletes of swimming. The present research has been conducted with semi-experimental and functional method. For doing so 25 men swimming athletes were randomly selected (N= 120). Statistical analysis was conducted with Pearson coefficient, correlated T-test, TE & SEE. The results of statistical analysis show that the method of Skin Fold Stat with hydrostatic criterion method has meaningful difference in society of swimmers. Also there is meaningful difference between body mass index and criterion method. There was not any meaningful difference between bio-electrical impedance and criterion method in swimmers. (TE=3.01, SEE=2.91, R=0.924, P=0.064). The findings show that that bio-electrical impedance in swimmer athletes is more suitable method.
