Purpose: This study investigated the effect of virtual reality and Schroth breathing exercises on the lung function characteristics of normal adults in their 20s. Methods: The subjects were randomly divided into groups with ten people each in the experimental groups, namely the virtual reality breathing exercise group (BBEG) and the Schroth breathing exercise group (SBEG), and the control group. The experimental groups performed each breathing exercise for 4 weeks. Subsequently, pulmonary function test indicators such as the forced vital capacity (FVC) and the forced expiratory volume (FEV1) were measured. Results: In the within-group comparison of the subjects before and after the exercises, there was a significant difference in the FVC and FEV1 (p<0.05), but there was no significant difference in FEV1/FVC. The result of the difference test between groups showed that there was a significant difference in FEV1/FVC after exercise (p<0.05). However, there were no significant differences in the remaining items (p>0.05). Conclusion: Improvement in lung function was seen in both exercise groups, and the changes in FEV1/FVC indicated significant improvement in the lung function of the experimental groups compared to the control group.

Purpose: In order to examine whether daily physical activity (DPA) can be considered the same as a regular exercise (RE) in patients with Heart Failure (HF), we examined the relationship between RE and DPA, and we explored the relationship of RE and DPA with exercise capacity and quality of life (QOL) in patients with HF. Methods: This cross-sectional, correlational study utilized pretest data (N=136) of a long-term intervention study. Data of the parent study were collected from May 1st to September 26th, 2013. Measures included questions about regular exercise, International Physical Activity Questionnaire, a 6-Minute Walk Test (6MWT), and the Kansas City Cardiomyopathy Questionnaire (KCCQ). The data were analyzed using descriptive analysis, Chi-square test, and ANOVA using the SPSS 21.0 program. Results: There were inconsistencies in measures between RE and DPA. About 42.0% of the participants engaging in health enhancing physical activity did not consider themselves to be regular exercisers. Depending on the levels of RE and DPA, significant differences in 6MWT and QOL were observed. Conclusion: RE is more likely to be related to the health status of patients with HF. Deliberate assessment and cautious interpretation of DPA in patients with HF is needed.

Purpose : It was to compare changes in respiratory function (pulmonary function, inspiratory function) after four weeks of inspiratory muscle strengthening training (diaphragmatic breathing with upper arm exercise, Power-Breathe breathing) for 36 healthy people. Methods : Subjects were randomly assigned to diaphragmatic breathing with upper arm exercise (Group I) and Power-breathe breathing (Group II) was conducted by the protocol for four weeks five times per week. As the main measurement method for comparison between groups For pulmonary function, Forced Vital Capacity (FVC) and Forced Expiratory Volume at One second (FEV1) were used, and for inspiratory function, Maximum Inspiratory Capacity (MIC), Maximum Inspiratory Pressure (MIP), and Maximum Inspiratory Flow Rate (MIFR) were used. Results : In changes in pulmonary function between groups, FVC and FEV₁ showed no significant difference, and in inspiratory function changes, MIC showed no significant difference, but in MIP and MIFR, Group B significantly improved over Group A. Conclusion : The progressive resistance training using the Power-breath device applied to the inspiratory muscle did not show a significant difference in the increase in the amount of air in the lungs and chest cage compared to the diaphragmatic breathing training accompanied by the upper arm exercise. However, by increasing the air inflow rate and pressure, it showed a more excellent effect on improving respiratory function.

Purpose : The purpose of this study was to investigate a comparative study on the effects of maximum voluntary ventilation (MVV) and thickness of the abdominal muscles through two Kegel exercise postures. Methods : Twenty eight (male= 7, female= 21) subjects participated in this experiment. They performed Kegel exercise in sitting and hooklying. The order of exercise was conducted in the order chosen by the subjects to exclude the learning effect. The MVV was measured using a spirometer. The thickness of the abdominal muscles were measured by ultrasound. The MVV and thickness of the abdominal muscles were measured according to the manual in a sitting and hooklying position before the experiment. After each exercise, the MVV and thickness of the abdominal muscles were also measured in the same way. A one way repeated measures analysis of variance (ANOVA) was used to compare the MVV and thickness of the abdominal muscles according to two postures and post hoc analysis, Bonferroni was used. Results : As a result of this study, significant differences in the MVV were observed after exercise than before exercise (p<.05). However, as a result of post hoc analysis, there was no difference in the MVV according to the postures (p>.05). Significant differences in thickness of the abdominal muscles were observed after exercise than before exercise (p<.05). However, as a result of post hoc analysis, there was no difference in thickness of the abdominal muscles according to the postures (p>.05). Conclusion : Based on the results of this study, the MVV and the thickness of the abdominal muscles were confirmed in the sitting and hooklying posture after Kegel exercise. However, further studies on vital capacity and abdominal muscles according to Kegel exercise postures should be conducted.

Patients with chronic obstructive pulmonary disease (COPD) frequently complain of dyspnea on exertion and reduced exercise capacity, which has been attributed to an increase in the work of breathing and in impaired of gas exchange. Although COPD primarily affects the pulmonary system, patients with COPD exhibit significant systemic manifestations of disease progression. These manifestations include weight loss, nutritional abnormalities, skeletal muscle dysfunction (SMD), cardiovascular problems, and psychosocial complications. It has been documented that SMD significantly contributes to a reduced exercise capacity in patients with COPD. Ventilatory and limb muscle in these patients show structural and functional alteration, which are influenced by several factors, including physical inactivity, hypoxia, smoking, aging, corticosteroid, malnutrition, systemic inflammation, oxidative stress, apoptosis, and ubiquitin-proteasome pathway activation. This article summarizes briefly the evidence and the clinical consequences of SMD in patients with COPD. In addition, it reviews contributing factors and therapeutic strategies.

Purpose: The aim of this study was to evaluate the effect of a breathing exercise intervention by measuring pulmonary function test (PFT) three times; preoperative, 3rd and 5th day after operation. Methods: This study was designed as a non-equivalent control group pretest-posttest design. A total of 55 patients with lung cancer were recruited from a Chonnam university hospital in Hawsun-gun, Korea from January to December 2008. Results: 'Forced Vital Capacity (FVC)' and 'Forced Expiratory Volume in 1 second $(FEV_1)$' were significantly improved in the experimental group than those in the control group (p<.05). Conclusion: Breathing exercise intervention was found to be effective in improving pulmonary function among lung cancer patients underwent lung lobectomy. Thus, the breathing exercise can be applied in hospitals and communities for patients with lung cancer as one of the nursing intervention modalities for their better postoperative rehabilitation.

In this study, coffee was shown to effectively inhibit L6 muscle cell death and ATP reduction induced by hydrogen peroxide damage. Additionally, two weeks of oral administration of 7 mg/kg coffee extracts to mice resulted in a 33% increase in treadmill running time relative to that seen in the distilled water administered group. Blood analysis showed decreased lactate content, which was increased by exercise. Thus, these data suggest that coffee intake may enhance exercise capacity and inhibit damage due to excessive exercise.
