Abstract


This study was carried out to know physical growth and maximum growth age of the growth-accelerating phenomena by semi-longitudinal research method. The subject of study were 463 persons (male;224, female;239) who are living in Pyung-Taek City
and
were
born form March 1 in 1974 to February 28 in 1975 and grew up until the third grade of high school.
@ES The results are as follows:
@EN 1. Physical growth and development
Body height grew one-step direct-development and body weight, chest-girth and sitting height grew two-step direct -development. Female excelled male in two-step development.
The age of cross-over between two sexes was between two sexes was between 10.5 to 13 years in body height, between 10.5 to 13.5 in body weight, between 12.5to 13.5 in chest-girth, between 11.5 to 13.85 in sitting height, but cross-over was not
found in
chest-girth. During this periods, female excelled male but after the periods, male excelled female again.
2. Physical and Nutritional Indices
In all cases of relative body weight, relative chest-girth and relative sitting, they were found to be increasing thereafter with advancing ages
The age of cross-over between two sexes was between 11.5 to 14.5 years in relative body weight, after 12.5 in relative chest-girth and after 10.5 in sitting height. During this periods, female excelled male but after the periods, male excelled
female
again.
Rohter index and Kaup index reached normal conditions as the age increase.
Verveack and Pelidisi index reached normal conditions as the age increase.
3. Maximum growth age of physical growth and development
In body height, MGA was 12.51 for male and 10.91 for female which showed that MGA for female appeared about 2 years earlier than for male.
In body weight, MGA was 12.99 for male and 12.00 for female which showed that MGA for female appeared a bout 1 years ealier than that for male.
In chest-girth, MGA was 13.24 for male and 12.5 for female which showed that MGA for both sexes appeared in similar periods.
In sitting height, MGA was 12.87 for male and 11.39 for female which showed that MGA for both sexes appeared in similar periods.
Maximum growth ages of physiques appeared in order of body height>sitting height>body weight >chest-girth.
