청소년기 한국 여자의 체격과 유연성과의 상관관계 = Studies on Physical Measurements and Flexibilities of Korean Schoolgirls at 15 to 18 years of age

다국어 초록 (Multilingual Abstract)

In order to investigate the physical growth and physical flexibilities of Korean school girls at puberty the stature, arm span, body weight, standing trunk flexion and trunk extension of 1301 subjects ranging from 15 to 18 years of age were measured. The correlation coefficients between the biometric data were calculated in each age group.
The results were revealed as follows;
1. The average statures were l55.22cm at age 15, 156.62cm at age 16, 156.66cm at age 17, 157.28cm at age 18, and the average stature growth per year was 0.69cm.
2. The average spans were 154.88cm at age 15, 155.90cm at age 16, 155.96cm at age 17, 156.52cm at age 18, and the average span growth per year was 0.55cm.
3. The average body weights were 48.76kg at age 15, 51.40kg at age 16, 52.50kg at age 17, 52.90kg at age 18, and the average body weight increase per year was 1.3Bkg.
4. The average growth per year of stature, span and body weight showed the largest value between 15 and 16 years of age. The stature was slightly longer than span in each age group, but the differences between stature and span became getting closer with the increase of age.
5. The average standing trunk flexion were 13.52cm at age 15, 14.48cm at age 16, 15.42cm at age 17 and 14.22cm at age 18, and these data indicated that the average standing trunk flexion were Increased by 0.96cm and 0.94cm a year up to age 17, but decreased by 1.20cm after age 17.
6. The average trunk extensions were 48.86cm in age 15, 51.60rm in age 16, 50.06cm in age 17, and 48.30cm in age 18. The average trunk extension were increased by 2.74cm from age 15 to 16, but decreased by 1.54cm from age 16 to 17, by 1.76cm from age 17 to 18.
7. The correlation coefficients between stature and span were very high ifove.0.8) in each age group, the correlation coefficients between stature and body weight, and between body weight and span were middle value in each age group.
8. The correlation coefficients between physical flexibilities (standing trunk flexion and trunk extension) were 0.27 at age 15, 0.18 at age 16, 0.22 at age 17, 0.19 at age 18. The correlation coefficients between physical flexibilities and biometric data were very low, and thus these two items had nearly no correlation.
9. The regression equations among all of the items in each age group were tabled for reference.
