The purpose of this study was an determine whether elastic band on treadmill training might effect the chest expansion and pulmonary function of the 20's men. 40 subjects with experimental group(male: 20) and control group(male: 20) was participated in experiment. During four weeks, each group participated thirty minutes for three times per week. Subjects were assessed using pre-value and post-value measurement chest length(chest length for resting, chest expansion) and pulmonary function(forced vital capacity, forced expiratory volume at one second, FEV1/FVC, peak expiratory flow, vital capacity, tidal volume, expiratory reserve volume, inspiratory reserve volume) by the CardioTouch 3000S(BIONET, USA). These findings suggest that experimental group can be used to improve chest expansion, pulmonary function than control group. In comparison of both groups, post-test was more improved in experimental group. In conclusion, experimental group helped improving function of pulmonary volume and respiratory muscle, and thus it indicates that the functions will be more improved through the continued respiratory exercise program.

Determination of preoperatibe pulmonary function is crucial in avoiding complications from pulmonary resection, especially pneumonectomy. Postoperative morbidity and mortality were correlated with the preoperative results of five widely used tests of pulmonary function in 40 patients who underwent pneumonectomy for bronchiectasis, pulmonary tuberculosis, and carcinoma of the lung. Factors analyzed following operation included 30-day mortality, the incidence of arrhythmia, the frepuency of respiratory complications, and the number of individuals requiring prolonged mechanical ventilation. There were statistically significant differences[p<0.001]in mean values among FVC, FEV1, FEV1/FVC and MVV. But the difference of the FEF25-75% was not statistically significant.

Objective: Patients with chronic obstructive pulmonary disease (COPD) may experience reduced physical activity and quality of life (QoL) due to decreased pulmonary function. The purpose of this study was to investigate the level of pulmonary function, physical activity, and QoL of COPD patients. Design: Cross-sectional observational study. Methods: This study examined the published data of the Korea National Health and Nutrition Examination Survey in 2015-2019. Among 39,759 subjects who participated for 5 years, data from 151 patients diagnosed with COPD were analyzed separately. For the pulmonary function, the results of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV6, forced expiratory flow 25-75%, and peak expiratory flow were observed. Physical activity was identified as frequency and duration. For the QoL, EQ-5D-3L evaluation results were examined, and the frequency and index of the Korean version were investigated. Results: In pulmonary function, all variables were found to be lower than age and weighted matched normal values. COPD patients showed to perform very low levels of high/medium physical activity and sitting time was confirmed to be more than 8 hours a day. In QoL, it was found that the highest reporting rate of some problems was the "pain and discomfort" and "mobility". Conclusions: It was found that COPD patients showed that the prevalence of circulatory disease was relatively high, lowered pulmonary function, and QoL. These can be improved through regular physical activity, and it is thought that this can be achieved through optimization of pulmonary rehabilitation.

The purpose of this study was to analyze the correlation between pulmonary function, basic physical fitness (PF), and physical activity (PA), and to compare the differences by gender in Korean college students. Measurements of body composition, basic PF, PA (questionnaire), and pulmonary function tests of forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) using a Quark pulmonary function test were carried out on 312 healthy participants (150 males [mean age: 19.29±1.72 years] and 162 females [mean age: 19.05±1.17 years]). The pulmonary function of male students was related to right-handedness, left-handedness, and back strength, and the pulmonary function of female students was related to all basic PF. The pulmonary function of male students was related to all PA variables, whereas the pulmonary function of female students was related to middle-intensity PA. The findings of this study suggest that male students need to increase PA, and female students need to improve basic PF to sustain a healthy pulmonary function. Understand gender differences for pulmonary function-related factors and the gender-specific educational efforts are needed to improve and maintain pulmonary capacity in college students.

Pulmonary function studies today are generally accepted as an integral part of the evaluation of poor-risk patients who are to have pulmonary surgery. The effect of various pulmonary surgery on lung function was investigated in 54 patients in whom comprehensive lung function test were performed before and between 2 months and 14 months after operation at the Department of Thoracic Surgery, Seoul National University Hospital. According to the result of analysis, the effect of pulmonary resection on forced flow rate was keeping with the change of lung volume, and the preoperative level of ventilatory function plays a major role in determining postoperative loss of functioning lung. Although all measures of expiratory flow [FVC, FEV1, FEFO.2-1.2, MEF50, FEF25-75] have the same percentage of reproducibility, but FEV1 shows most sensitive, reliable linear correlation with the functioning pulmonary tissue loss than other parameters. The linear regression lines derived from the correlation between preoperative [X] and postoperative [Y] FEV1 on various surgical procedures were as follows: 1. Y = 0.57X 0.03. in pneumonectomy group of lung cancer[r=0.84]. 2. Y = 0.56X + 0.33. in lobectomy group of lung cancer[r=0.79]. 3. Y = 0.69X + 0.25. in lobectomy group of pulmonary infection[r=0.91].

Pneumonectomy on a patient with documented poor pulmonary function indicating a contraindication to surgery can be associated with a high risk of serious postoperative morbidity or mortality. However the usual criterias, on the performance of a pneumonectomy on a high risk patient based on the preoperative assessment of the pulmonary function may not sometimes predict with accuracy the operative outcome in the postoperative period. We recently performed pneumonectomy with good results on a patient with poor pulmonary function that would otherwise have been an absolute contraindication to surgery by usual criteria.

Objective: The objective of this study was to investigate the effects of Schroth's three-dimensional exercises in combination with respiratory muscle exercise (SERME) on Cobb's angle and functional movement screen (FMS). Design: Randomized controlled trial. Methods: Fifteen subjects with scoliosis were randomly assigned to two groups. Eight subjects were assigned to the experimental group and seven subjects were assigned to the control group. The experimental group underwent SERME using SpiroTiger (Idiag, Switzerland), while the control group performed only the Schroth's three-dimensional exercises (SE). Both groups performed exercises for one hour per day, three times a week for eight weeks. Cobb's angle, pulmonary function (forced vital capacity, forced expiratory volume at one second, and peak expiratory flow) and FMS were measured before and after the experiment. Results: After intervention, the SERME group showed a significant difference in Cobb's angle, FMS scores, and pulmonary function as compared to before intervention (p<0.05). In the SE group, there was a statistically significant difference in Cobb's angle, pulmonary function, and FMS scores compared to before intervention (p<0.05). The SERME group showed a significant difference in Cobb's angle and peak expiratory flow in pulmonary function compared to the SE group (p<0.05). Conclusions: The results suggest that SERME could be a more effective intervention for improvement of the Cobb's angle and pulmonary function for scoliosis patients.

It is known that a pulmonary rehabilitation program improves dyspnea and exercise tolerence in patients with chronic obstructive pulmonary disease. However, it is also known that although it does not improve pulmonary function. This study was performed to evaluate the effect of a 4 week pulmonary rehabilitation on pulmonary function, gas exchange, and exercise tolerance in patients with chronic obstructive pulmonary disease. The pulmonary rehabilitation programs included breathing exercises, such as pursed-lip breathing and diaphragmatic breathing, upper-limb exercises, and inspiratory muscle training. These activities were performed for 4 weeks in twenty one patients with chronic obstructive pulmonary disease. Pre and post-rehabilitation pulmonary function and exercise capacities were compared after the 4 week period. Results are as follows: 1) Before the rehabilitation, the predicted value of FVC and FEV1 of the patients were 70.3$\pm$16.7% and 41.1$\pm$11.9% respectively. These pulmonary functions did not change after pulmonary rehabilitation. 2) Aloility of walking a 6 minute distance (325.29$\pm$122.24 vs 363.03$\pm$120.01 p=.01) and dyspnea (p=.00) were significantly improved after rehabilitation. Thus showing that pulmonary rehabilitation for 4 weeks can improve exercise performance and dyspnea in patients with chronic obstructive pulmonary disease.

Respiratory effects in full time welders include bronchitis, airway irritation, lung function changes, and lung fibrosis. Welder's pneumoconiosis has been generally determined to be benign and not associated with respiratory symptoms based on the absence of pulmonary function abnormalities in welders with marked radiographic abnormalities. Accordingly, to investigate pulmonary function changes during 60 days induced by welding-fume exposure, male Sprague-Dawley rats were exposed to manual metal arc-stainless steel (MMA-SS) welding fumes with concentrations of 64.8$\pm$0.9 mg/$m^3$ (low dose) and 107.8 $\pm$ 2.6 mg/$m^3$ (high dose) total suspended particulates for 2 hr/day, 5 days/week in an inhalation chamber for 60 days. Pulmonary function was measured every week with whole body plethysmograph compensated (WBP Comp, SFT38116, Buxco Electronics, Sharon, CT). The rats exposed to the high dose of welding fumes exhibited statistically significant (p<0.05~0.01) body weight decrease as compared to the control whereas cell number increase of the bronchoalveolar lavage fluid (BALF) (total cell, macrophage, polymorphonuclear cell and lymphocyte) during the 60 days exposure period. And only tidal volume was significantly decreased in dosedependantly during 60 days of MMA-SS welding fume exposure. This pulmonary function change with inflammatory cell recruitment confirms the lung injury caused by the MMA-SS welding fume exposure.

PURPOSE: To prevent secondary complications from decreased pulmonary functions and promote neurological recovery, identification of respiratory capacity change patterns depending on different postures of stroke patients and investigation of their properties are needed for active rehabilitation. Therefore, this study was conducted to investigate the changes in vital capacity in response to different positions and to implement the results as clinical data. METHODS: A respiratory function test was administered to 52 patients with stroke in the sitting, supine, paretic side lying, and non-paretic side lying positions. Pulmonary function indexes used for comparison were forced vital capacity (FVC), forced expiratory volume at 1 second (FEV1), forced expiratory flow 25-75% (FEF 25-75%), and maximum voluntary ventilation (MVV). One-way repeated ANOVA was used for analysis, and post hoc analysis was conducted using least significant difference (LSD). RESULTS: All pulmonary function indexes were measured in the order of sitting, paretic side lying, supine, and non-paretic side lying positions. Excluding the FEF25-75% and MVV of the supine compared with the paretic side lying position, all other pulmonary function indexes differed significantly (p<.05). CONCLUSION: There are differences in pulmonary function indexes depending on different postures of stroke patients, and the study showed that the non-paretic side lying position yielded the greatest effect on lung ventilation mechanisms. Based on these results, appropriate postures need to be considered during physical therapy interventions for stroke patients.
