Abstract
The purpose of this study was to investigate body mass index (BMI), body fat percent (%BF) and waist-hip ratio (WHR) of physical education male students of Shahid Chamran University and comparison with national and international body composition standards. Material : Subjects were seventy five male students physical education male students of Shahid Chamran University of mean age (23.21±2.78), mean height (174±5.71) and mean weight (70.07±9.43) who were selected randomly. Some of body composition indices were determined with body composition analyzer apparatus (bioelectrical impedance apparatus). Results : Descriptive characteristics of subjects include: body fat percent (19.37±3.62), waist-hip ratio (0.80±0.037) and body mass index (23.18±2.68). To categorize and regulate data we used descriptive analyzes, to calculate Pearson correlation coefficient we used presumption analyzes and to compare the obtained data with national standards we used T-test statistical procedure. There are significant correlations between body mass index and waist-hip ratio (P=0.709, r=0.001), between body mass index and body fat percent (P=0.783, r=0.001) and between body fat percent and waist-hip ratio (P=0.809, r=0.001). There are significant differences between mean body mass index and its national standard (P=0.001), between mean waist-hip ratio and its national standard (P=0.001) and between mean body fat percentage and its national standard (P=0.001). Conclusions : Results revealed that according to national standards of body fat percentage and body mass index of subjects, they were assigned to more than intermediate limitation; it may be due to abnormal nutrition, unregulated exercise or physical activity and heredity.

Introduction1 Overweight and obesity are major, and increasing, public health concerns in all parts of the globe
Longitudinal study which it performed in Hardward University during 27 years on 19292 students with mean age 46.6 years old had been shown that rate of mortality in men who had body mass index (BMI), 26 kg/m2, 1.67 times is more than men who had body mass index, 22,5 kg/m2 (Altan O. et al 1999)
We investigated BMI, percent body fat, and waist - hip ratio in male students of physical education and sport sciences field and we compared them with Iran national and international standards
Summary
Introduction Overweight and obesity are major, and increasing, public health concerns in all parts of the globe. The use of BMI in this way has a number of limitations, including its inability to distinguish between fat mass and non-fat mass (Norgan & Ferro-Luzzi, 1982; Garn et al 1986; Ross et al 1988) These limitations may become an important issue when comparing ethnic groups with distinctively different body proportions or physiques. We investigated BMI, percent body fat, and waist - hip ratio in male students of physical education and sport sciences field and we compared them with Iran national and international standards. We measured body mass index (BMI), percent body fat (%BF), and waist to hip ratio (WHR) by using Bioelectrical Impedance apparatus Subjects Statistical population included 162 students of physical education and sport sciences field of Shahid Chamran University Ahwaz Iran and we selected simple randomly 75 students from statistical population. To demonstrate means and standard deviation of study variables (BMI, %BF, and WHR) we used quantify statistical procedures and to determine relationships between measured variables - Pearson correlation coefficient; to determine difference between measured variables and Iran national and international standards we used independent T-
