In hold that the pulmonary functions which is important situation that the national physical power, at firstly, from age 10 to age 29 young men and women 1,540 person for the progress of grew up, and them to by each aged viewing transition for pulmonary functions physical examination record is as following; and to measure normal Person with comparison by each others pulmonary functions was gained as the results of follows. 1) Frequency of Breathing: It was same the male and female age at 10 per minute over or less of 20 times, but, at age 16 to 17 was $15{\sim}16$ times, and had to precensed compare constant value. 2) Vital Capacity: At the grew up Pregress term as the body stature, age 10 to 17 or 18, had to showing rapidly increasing, but the after Probably constant. The comparison value in man and women in progress of growth up was about $200{\sim}300ml$, and after growth of progress are about 1,500ml, add in men was presence more highly value. 3) Tidal Volume: At a9e 10 was 365m1, but, it was continuing increasing, an4 at age 20 is about 500m1, and the different in men and women about $20{\sim}30$ times and had precense highly value at men. 4) Breathing holding time: It was presence same at male and femele 10 to 13, from 35 second to $37{\sim}38$ seconds, and had to Presence a slight increasing, but, may has to final of the growth progrees age at 14, it should be presence rapidly increasing and the after probably presence as same value but, than female at male is high record average value of $7{\sim}8$ seconds.
