Abstract

Body composition analysis is an important clinical marker for risk of obesity- influenced condition, also the anthropometry science survey relationship between athletic performance and functional anatomical systems output, such as local strength, power development anaerobic and endurance potentials.The purpose of this project was cross validation regression equations and the accuracy determination for estimating body density (BD) in the male wrestlers, using noninvasive skinfold method. One hundred and forty youth athletes (age:23/4=0/24 years, heigh: (72.4=0.9 cm and weight: 79/4=2/2 kg, Mean= SEE) without any history physiological or skeletal diseases were participated during hydration condition. Fat thickness was measured at 9 sites, using the desitometric skinfold method. Predition equations for BD and body fat (BF) were cross-validated using SLOAN (EQ1), JACKSON (EQ2), LOHMAN&Brozek equations respectively. Conclusion: The best BD & BF selected equations by Sloan and Jackson equations are as follow:BD1= 0.97(BD3)-0.029 [R2=0.987, SEE=0.002, P< 0.001] BF1= 1.358(BF3)-1.089[R2=0.938, SEE=2/135, P<0.00l] These data indicated that EQ1&EQ2 generalized multiple regression equations are valid estimating anthropometric bd of Iranian male wrestlers.
