Abstract

This study has been aimed to study of the body composition by Dual Energy X-ray absorptiometry of 12 athletes of Korea National team and 15 adults in control group by Nuclear department of J.I. Hospital Seoul, Korea.
The average age was 21.9±1.1 years old in athletes and 21.2±2.1 years old in adults, respectively.
The average body fat amount and percentage of athletes and adults group obtained by the DEXA method is 9.9±2.1kg (14.2±2.2%) and 14.7±5.9 kg (22.1±5.4%), and on the other hand that anthropometric is 13.76±1.24kg (20.0±1.8%) and 13.03±2.17 kg (19.8±3.3%) respectively.
There is statistically difference between athletes and adults of the body fat amount obtained by DEXA method (p<0.01) and that by anthropometric method is no statistically significant difference between them (N.S.)
It is therefore possible to compare the latest results obtained by the DEXA method with those obtained by the traditional method. Looking at these comparisons, it can be said that, overall, the physical standards of Korean adult people have been greatly improve and that is no doubt largely due to the improvement in their diet. This is due mainly to the nation’s economic development and this improvements in physique is accompanied by an increase in the body fat percentage.
The rate of body fat weight is lower athletes than adults in control group.
