Purpose: This study was to examine the effects of an exercise program on physical fitness, cardiopulmonary function and life satisfaction for adult women. Method: The exercise program combined dance and resistance training. The subject group consisted of 114 women aged between 33 and 60. Three 8-week sessions consisted of 55-80% HR max for 60-90 minutes a day and 3 times a week from March to November, 2004. Data were collected through pre- and post-exercise tests before and after each session. Data were collected with dynamometer, sphygmomamometer, spirometer and structured questionnaires. Data were analyzed employing descriptive statistics and paired t-test with SPSS/PC(10.0version) program. Results: There were significantly positive changes in muscle strength, flexibility, balance quality, forced vital capacity and life satisfaction, but no significantly positive changes in agility and blood pressure. Conclusion: This study showed that an exercise program has partially positive effects for adult women. The results of this study suggest that there should be programs of continuous exercise at community health centers for adult women's health.

Purpose: The purpose was to determine whether the application of the abdominal drawing-in maneuver (ADIM) and abdominal expansion maneuver (AEM) to stroke patients would affects their trunk stability, balance, pulmonary function, and grip strength. Methods: The subjects were 36 stroke patients who were randomly and equally assigned to an ADIM group (n=12), an AEM group (n=12), and a control group (n=12). The intervention was applied to each group three times per week, 30 minutes each time, for four weeks. Outcome measures were grip strength, modified functional reach test (mFRT) and pulmonary function. Pulmonary function were measured force expiratory volume at one second (FEV1), forced vital capacity (FVC), FEV1/FVC and peak expiratory flow (PEF) values. Results: The results of the three groups showed statistically significant improvements in grip strength. The AEM group showed significantly greater differences in grip strength than either the ADIM group or the control group. In the anterior mFRT, the ADIM group showed significantly improvements than the control group. The ADIM and AEM groups were showed statistically significant greater improvements in PEF between the baseline and post-intervention and the post-analysis revealed that the AEM group showed significantly greater improvements than the control group. Conclusion: The results of this study indicate that the ADIM and AEM were effective in improving the PEF of pulmonary function. The ADIM was more effective than AEM in trunk stabilization.

Purpose: The purpose of this study was to examine correlations among UPDRS, respiratory function, and senior fitness and to investigate the effects of restrictive respiratory function on these factors in Parkinson's disease patients. Methods: Subjects (n=25, Hoehn & Yahr (H&Y) stage: 2-3, $69.3{\pm}5.9$ yrs) from D Hospital Parkinson's Disease Center at Busan metropolitan area in the Republic of Korea volunteered for this study. They performed the pulmonary function test, UPDRS, and the senior fitness test. SPSS 18.0 was used for analysis of data, and the collected data were analyzed using Pearson's correlation coefficient (n=25). In addition, Independent t-test was used for determination of differences between two groups (between the normal pulmonary function group (n=10) and the restrictive pulmonary function group (n=10)). Results: Forced vital capacity (FVC (L)) showed significant negative correlation (r=-0.44, p<0.05) with H&Y stage in Parkinson's disease patients, and chair stand showed significant negative correlations (r=0.41, 0.43, 0.42, p<0.05) with FVC (L), FVC (%), and FEV1 (L). FVC (%) showed significant positive correlations (r=0.44, r=0.44, p<0.05) with right and left back scratch. In addition, the restrictive respiratory function group showed significantly lower FVC (%) (p<0.01) and was significantly slower (p<0.05) in the 8-foot up-and-go test than the normal respiratory function group. Conclusion: In conclusion, these results suggest that restrictive respiratory function in PD was related to H&Y stage. In addition, agility of PD patients was lower in the restrictive respiratory function group than in the normal function group.

천식환자의 폐활량 측정 및 관리는 정기적으로 검사되어 관리될 필요가 있는 매우 중요한 관리 항목이다. 본 연구는 천식환자의 폐활량을 정기적으로 관리할 수 있도록 PC-기반 폐활량기를 이용한 천식환자의 폐활량 측정 및 관리 시스템의 설계 및 구현에 관한 연구이다. 폐활량 검사는 크게 3종류 구성되며, 본 연구는 노력성 폐활량 검사(Forced Vital Capacity Test)를 1차적으로 설계 및 구현 방법을 제안하였다. FVC 검사의 목적은 폐질환의 진단, 중증도 그리고 치료효과 판정, 기관지 천식의 진단 및 관리, 수술시 마취방식의 결정 등으로 무엇보다 정확한 검사와 정기적인 검사를 필요로 하는 중요한 검사이다. FVC 검사는 검사과정에서 천식환자에게 많은 노력을 필요로 하는 힘든 검사로서 검사자의 도움이 필수적이므로 폐활량 검사 프로그램 개발에 있어 고려되어 알고리즘이 효율적으로 개발되어야 한다. 본 시스템은 휴대형 폐활량기(Spirometer)를 PC에 연결하고, 폐활량을 측정할 수 있도록 구성되었고, 검사 내용은 PC의 DB에 저장하고, 추후에 정기적으로 서버의 DB로 전송함으로서 보다 더 폭넓은 관리를 가능하도록 하며 천식환자는 서버가 제공하는 웹 사이트를 이용함으로서 자신의 건강관리를 가능하도록 구성된다. FVC 검사 프로그램은 정확한 검사와 편리한 사용자 인터페이스를 제공하도록 설계 및 구현하였고 따라서 자체 개발된 폐활량기를 PC-기반 프로그램으로 제어 가능함으로서 추후 다양한 임상실험의 데이터 확보, 기능의 확장과 성능의 개선을 할 수 있고, 좀 더 편리하고, 정확한 폐활량측정이 가능 할 것이다.

The aim of this study was to investigate the effects of respiratory muscle training (RMT) with abdominal drawing-in maneuver (ADIM) on pulmonary function. Twenty-two subjects with restrictive breathing participated in this study. All the subjects were randomly assigned to three groups (7 subjects in RMT group, 7 subjects in RMT with ADIM group, 8 subjects in control group). The first group performed the RMT by using incentive respiratory spirometer (IRS). The second group performed the RMT by using IRS and the ADIM by using a Stabilizer. The exercises were conducted over four days. The pulmonary function was evaluated using the spirometer to measure the force exploratory volume in 1 second ($FEV_1$) and forced vital capacity (FVC). Measurements were conducted on the first day and the last day. A paired-t test was used for pre-post changes and the change rates in FVC and $FEV_1$ among each group were investigated by a one-way ANOVA. The findings of the the study were as follows: 1) There were significant differences of FVC and $FEV_1$ between pre and post in the two training groups (p<.05) 2) There was no significant difference of the change ratio the FVC and $FEV_1$ between the RMT group and RMT with ADIM group. Therefore, it is concluded that respiratory muscle and ADIM training, combined with two methods of treatment would suggest positive evidence for improving pulmonary function.

Background: Farinelli breathing (FB) exercise is a typical breathing exercise used by singers. This study aimed to compare effects of FB exercise and diaphragmatic breathing (DB) exercise on respiratory function and symptoms in patients with chronic obstructive pulmonary disease (COPD). Methods: Sixteen patients aged 51-80 years with mild or moderate COPD were recruited for this study. They were divided into two groups: DB group (n=8) and FB group (n=8). Both groups received complete breathing exercise training five times per week for 8 weeks. Their respiratory functions, COPD symptoms, cytokine levels, and oxidative stress variables were analyzed during pre- and post-tests. Dependent variables were compared between pre- and post-tests using paired t-tests. An independent t-test was used to compare variables between the groups. Differences were considered significant at p<0.05. Results: The maximal expiratory pressure (MEP), maximum oxygen consumption (VO₂max), and COPD Assessment Test (CAT) scores changed significantly in the DB group after the 8-week intervention compared to those at pre-test, whereas force vital capacity, forced expiratory volume in the first second, maximum voluntary ventilation, maximal inspiratory pressure (MIP), MEP, VO₂max, CAT score, tumor necrosis factor-α, and malondialdehyde level changed significantly in the FB group at post-test compared to those at pre-test. Moreover, both MIP and MEP in the FB group were significantly higher than those in the DB group. Conclusion: FB exercise improved respiratory functions and COPD symptoms of patients with COPD. It might be an alternative breathing exercise in pulmonary rehabilitation programs for patients with COPD.

The coronavirus disease 2019 (COVID-19) pandemic has been ongoing for more than 2 years. Many patients who recover from severe acute respiratory syndrome coronavirus 2 infection continue to have aftereffects such as dyspnea and fatigue, which may lead to functional decline. Therefore, the need for managing these symptoms using methods such as pulmonary rehabilitation (PR) has emerged. The purpose of this study was to report the effectiveness of PR in five patients with acute COVID-19. PR was performed in patients with persistent dyspnea and oxygen demand after COVID-19. All five patients were able to maintain an independent functional status before COVID-19. However, after acute COVID-19, they were unable to walk independently and needed assistance for activities of daily living due to dyspnea and fatigue. Therefore, they were referred to rehabilitation units, and PR was performed. The modified Medical Research Council dyspnea scale, maximal expiratory pressure (MEP), 6-minute walking test, forced vital capacity, and grip strength were assessed before and after PR, and the results were compared. After PR, the parameters improved, except for the MEP in one patient (patient 3) and the grip strength in another patient (patient 4). After PR, two out of five patients returned to work and the other three returned home. Therefore, we conclude that PR is necessary for patients with acute COVID-19 with activity limitations.

According to previous studies, an impaired pulmonary function is associated with arterial stiffness (AS). The pulse pressure (PP) is an important predictor of AS, but the association of an impaired pulmonary function with the PP is unclear. Therefore, this study assessed the associations between the PP and the predicted forced vital capacity (predicted FVC) and predicted forced expiratory volume in one second (predicted FEV₁) in Korean non-smoking adults. The data obtained from 6,857 adults during the 2013~2015 Korean National Health and Nutrition Examination Survey were analyzed. After adjusting for the related variables, the ORs of restrictive pulmonary disease (RPD, the predicted FVC<80.0% with FEV₁/FVC≥70.0%) using the normal PP group (PP≤60 mmHg) as a reference group was significant for the high PP group (PP>60 mmHg; 1.337 [95% confidence interval (CI), 1.049~1.703]). In addition, the ORs of obstructive pulmonary disease (OPD, FEV₁/FVC<70.0%) using the normal PP group as a reference group were significant for the high PP group (1.339 [95% CI, 1.093~1.642]). In conclusion, a high PP is positively associated with both RPD and OPD in Korean non-smoking adults.

Objectives. Changes in lung function are frequently used as biological markers to assess the health effects of criteria air pollutants. We tried to formulate the prediction models of pulmonary functions based on height, weight, age and gender, especially for children aged 12 years who are commonly selected for the study of health effects of the air pollution. Methods. The target pulmonary function parameters were forced vital capacity(FVC) and forced expiratory volume in one second(FEV1). Two hundreds and fifity-eight male and 301 female 12-year old children were included in the analysis after excluding unsatisfactory tests to the criteria recommended by American Thoracic Sosiety and excluding more or less than 20% predicted value by previous prediction equations. The weight prediction equation using height as a independent variable was calculated, and then the difference of observed weight and predicted weight (i.e. residual) was used as the independent variable of pulmonary function prediction equations with height. Results. The prediction equations of FVC and FEV1 for male are FVC(ml) = $50.84{\times}height(cm)+7.06{\times}weight$ residual 4838.86, FEV1(ml) = $43.57{\times}height(cm)+3.16{\times}weight$ residual - 4156.66, respectively. The prediction equations of FVC and FEV1 for female are FVC(ml) = $42.57{\times}height(cm)+12.50{\times}weight$ residual - 3862.39, FEV1(ml) = $36.29{\times}height(cm)+7.74{\times}weight$ residual - 3200.94, respectively.
