1. Physical Growth and Development
a) Rapid growth has been observed among boys in age 11∼15 and 10∼14 of girls.
b) Physical growth and developments such as height, weight, chestgirth and sitting height among female students were superior to those among male students in ages 11, 12, 13 and 14.
c) The maximum annual growth velocities were as followings:
Height: Boys-7.4㎝ from 13 to 14 years of age Girls-11.1㎝ from 11 to 12 Weight: Boys-6.5㎏ from 14 to 15 years of age Girls- 6.7㎏ from 11 to 12
Chestgirth: Boy-4.4㎝ from 14 to 15 years of age Girls- 6.0㎝ from 11 to 12
sitting height: Boys-4.0㎝ from 14 to 15 years of age Girls- 5.1㎝ from 11 to 12
The greatest individual differences in growth and development were observed also during maximum growth age.
d) Increases of physical conditions during 6~17 years of age in comparison with those in age 6were as followings:
Height: Boys-53.3㎝ (46.6%), Girls-42.2㎝ (37.1%)
