Growth and development of extremity length and trunk width in Dalian students

Objective: To know the extremity length and trunk width and trunk width and growth rule in Dalian students. Methods: According to "Handbook of Anthropometry" the upper extremity length, shoulder breadth, lower extremity length and pelvis breadth of 1 210(boys 598, girls 612) Dalian students(aged 7-17 years) were measured and the data were compared with that of 1987. Results: With age increase, the upper extremity length, shoulder width, lower extremity length and pelvis width of Dalian students increased gradually. The age of peak height velocity for male and female groups in the upper extremity length, shoulder width, lower extremity length and pelvis width were 12. 50 and 10. 40, 12.76 and 12.63, 10. 74 and 9.63, 12.58 and 11.12 years respectively. There was positive relation between upper extremity length and stature, shoulder width and stature, lower extremity length and stature, pelvis breadth and stature. Conclusion: Difference of extremity length and trunk width between sexes is obvious, and growth and development of extremity length increase with age.
