| Research Abstract |
(1) 1093 boys and girls aged from 3 to 14 were measured to their spine curvatures, difference of bi-acromion height, weight distribution between right and left and location of the center of gravity in anterior-posterior axis of feet in normal relax standing posture.
Children aged from 3 to 5 had a tendency to be inclined backward in head and neck position while boys and girls aged from 8 to 14 showed to be inclined forward in head and neck position and a tendency to be warped back.
(2) Boys was born from January to March showed significantly smaller in the morphological data than those from April to December, but significant difference showed no change in girls of each groups.
(3) Coordination tests such as jump over & crawl under, side step, tapping, stepping and whole body reaction time showed the most gain per year ranging from 4 to 10 years of age in both sexes, but their gains showed little increase thereafter.
Several strength tests such as grip strength, leg strength, and vertical jump showed little gain per year ranging from 4 to 13 years of age in both sexes, but leg strength are improved gradually in later ages for boy but the rate of development showed no change at later ages for girl.
Measured values of sitting trunk flexion appeared little decrease from 4 to 9 years of age in both sexes.
