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
athlets and adults group obtained by the DEXA
method is 9.9±2.1 kg (14.2±2.2%) and 14.7±5.9 kg
(22.1±5.4%), and on the other hand that
anthropometric is 13.76±1.24 kg (20.0±1.8%) and
13.03±2.17 kg (19.8±3.3%) respectively.
There is statistically difference between athlets 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 improvement
in physique is accompained by an increase in
the body fat percentage.
The rate of body fat weight is lower athletes than
adults in control group.
