심동원 순천향대학교 1982 논문집 Vol.5 No.3
In order to evaluate the age-related changes of pulmonary function, the vital capaitices, tidal volumes, expiratory reserve volume and respiratory rates were measured in 1,592 normal men and women aged between 10 and 49 years. The volunteers were composed of 437 boys and 473 girls aged between 10 and 18 years, 408 adult men and 218 adult women aged between 19 and 29 years, and middle aged men in their thirties and fourties. The degrees of con commitunt rise in lung volumes in accordance with the growth of physical body feature were measered in boys and girls and reflections of body status in lung volumes were analyzed for the young adults. The age dependency of the inverse relation between lung volume and body weight was also checked of the middle aged men. Results are as follows: 1. During the age of 10 to 18, both the vital capacity and tidal volume increased with the progress of age: 2. The vital capacities and tidal volumes of young adults aged between 19 and 29 years remained constant. 3. The vital capacities and tidal volumes of middle aged men are found to be decrease with the progress of age. However, the decrease of vital capacities are more extensive than tidal volumes.

To investigate the effect of extreme high temperature on the cardiopulmonary function, we measured the heart rate, blood pressure, lung volumes, and breath-holding time before and during exposure to 70℃ environment in male adults. 1) The heart rate demonstrated exquisite sensitivity to extreme high temperature; exposure to heat increased the heart rate from 75 bpm to 124 bpm(65% increase). 2) There was a tendency for both systolic and diastolic pressure to decrease, which was not statistically significant. 3) While the exposure increased the respiratory rate from 19/min to 28/min (47% increase), it decreased the tidal volume from 566ml to 314ml. 4) The vital capacity decreased from control of 4.31 L to 3.26 L during exposure. The exposure also decreased the maximum breathing capacity (before exposure, 99 L; during exposure, 56 L0. 5) The breath-holding time decreased from 48 sec to 38 sec during exposure.

We evaluated the effect of physical training on the cardiovascular and respiratory function after exercise loads in adolescents (age ; 20-29) and in adults (age ; 40-59) who have just finished their physical growth and hence are at their peak in the physical capability. The results of the comparative study on the training effect were as follows 1. The cardiovascular and respiratory function in control group and trained group in adolescents 1) Heart rate and Blood pressure The resting mean heart rate in the trained group (physical student : 66.5 ±3.8bpm)was 10% lower than that in the control group (medical students : 73.5±4.7 bpm) The average systolic and diastolic pressure 118.3±5.2 and 80.4±4.9 mmHg respectively This values could be considerated to be not significantly different from systolic and diastolic pressure of the average Korean (113/73 mmHg) 2) Respiratory rate and volume Respiratory rate in medical student was 14.4±1,8 Per minute physical student was 12.1±1.3 per minute Tidal Volumn was 543.6±84.4 and 578.7 ±28.2 ml, respectively In physical student Respiratory rate was 16% lower and Tidal volume was 6% higher than in medical student 2. The Cardiovascular and Respiratory function in the control group and the trained group in middle aged adults 1) Heart and Blood pressure Resting heart rate in the trained group who have under gone physical exercise at a constant load was 69.1±6.6bpm : this values was 8% lower than that in the age-matured control group (74.7±3.6 bpm) while the systolic and diastolic Blood pressure in control group (134.7±3.9 and 84.3±3.4 mmHg) was similar to those in the age-matured average Koreans (131.1, 81.1) those in trained group (142.6 ±83.1, 100.3±6.3) tended to be higher than there of control : However, it didn't reach the statistical significance 2) Respiratory rate and Tidal volumn As was the case with the Heart, rate, Respiratory rate was 12% lower in the trained group (14.0±1.8) than in the control group (16.1±2.0) In contrast, resting Tidal volumn was 16% greater in the trained group (494.4±28.3) than in the control group (594.6±55.0) 3. The differential effect of physical training between adolescents and in middle aged-adults Both in adolescents and in middle aged-adults, Heart rate Respiratory rate were 9% and 14% lower in trained group than in control group respectively, Tidal volume was higher The results suggest that, both in middle aged-adults and in adolescents, the effect of training on the cardiovascular and respiratory rate function was promoted by-10.3%

In ho1d that the pulmonary functions which is important situation that the national Physical power, at firstly, from age 10 to age 49 men and women 1,596 preson 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 fo11ows. 1) Frequency of Breathing: It was same the male and female age at 10 per minute over or less of times, but, at age 16 to 17 was 15∼16 times, and bad 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 men and women in progress of growth up was about 200∼300mι and after growth of progress are about 1,500mι, and in men was presence more highly value. 3) Tidal Volume: At age 10 was 365mι, but, it was continuing increasing, and at age 20 is about 500mι, and the different in men and women about 20∼30 timers 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∼38 seconds, and had to presence a slight increasing, but, may has to final of the growth progress 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∼8 seconds.
