In this study, we investigate the effect of twenties female caffeine addiction on cardiorespiratory capacity. For this study, we divided 35 female students at H university into caffeine addict group(n=17) and none caffeine addict group(n=18). Measure maximal oxygen uptake, maximal energy consumption and METs using Cycle Ergometer to assess cardiac capacity. Measure peak inspiratory pressure, peak inspiratory flow rate, peak inspiratory capacity, average inspiratory pressure, average inspiratory flow rate, average inspiratory capacity using Power Breathe K5 to assess respiratory capacity. As a result, cardiac capacity showed a statistically significant decrease in maximal oxgen uptake and METs compared caffeine addict group to none caffeine addict group(p<.001). respiratory capacity showed a statistically significant decrease in peak inspiratory pressure(p<.05), peak inspiratory flow rate(p<.01), average inspiratory pressure(p<.01), average inspiratory flow rate(p<.01), compared caffeine addict group to none caffeine addict group. Combining the results of the study, we could see that caffeine addiction reduces the cardiorespiratory capacity in twenties female. Therefore, it could be used as a basis date to prevent caffeine addiction for twenties female.

PURPOSE: This study investigated the immediate effect of inspiratory muscle training with whole-body vibration on the pulmonary function of subacute stroke patients. METHODS: All participants (n=30) were allocated to the following groups: (1) the inspiratory muscle training group with whole-body vibration (n=10), wherein the patients received inspiratory muscle training with whole-body vibration comprising 3minutes of vibration per session and respiratory training of 30 times and 2 sessions for one day. (2) the inspiratory muscle training group with visual feedback (n=10), wherein the patients received inspiratory muscle training with visual feedback. (3) the inspiratory muscle training group (n=10), wherein the patients received inspiratory muscle training. RESULTS: After the experiment, the inspiratory muscle training group with whole-body vibration exhibited significantly higher forced vital capacity, forced expiratory volume at 1 second, peak inspiratory flow rate, maximal inspiratory pressure, and chest expansion (p<.05), compared to the other groups. Inspiratory muscle training group with whole-body vibration had significantly higher peak expiratory flow rate and maximal voluntary ventilation than the other groups (p<.05). CONCLUSION: These results show that pulmonary function, maximal inspiratory pressure, and chest expansion were significantly better in the inspiratory muscle training group with whole-body vibration than in the other groups. Thus, this treatment will help recovery of pulmonary function in stroke patients.

Purpose: The purpose of this study was to identify the effect of a kinesio tape on inspiratory muscle training(IMT) to improve muscle strength, endurance and pulmonary function. Methods: Healthy 20 males were divided into IMT group (control group) and IMT with tape group (experimental group). The same IMT program was applied to both groups using the Respifit S for four weeks, three times a week, a total 12 times. To exprimental group, kinesio tape was applied on the inspiratory agonist diaphragm and the accessory inspiratory muscle scalene, sternocleidomastoid, pectoralis minor. The inspiratory pulmonary muscle strength was measured by the maximal inspiratory pressure (PI max) and minute volume (MV) using the Respifit S and the pulmonary function were measured peak expiratory flow (PEF), forced vital capacity (FVC), forced expiratory volume in 1sec (FEV1), FEV1/FVC using the Spirometer and compared before and after. Results: Results showed that the PI max in the two groups increased significantly and experimental group increased more effectively than that of control group. However, only MV showed a significant increase in experimental group but was not significantly different between the two groups. PEF and FEV1/FVC are significantly increased in both groups, but they did not make much difference between two groups, and the FVC for the two groups did not increase significantly. FEV1 increased significantly only with control group, but did not make a difference with experimental group. Conclusion: These result show that the PI max value for experimental group increased significantly than that of control group. Therefore kinesio tape maximizes inspiratory muscle exercise effect on muscle strength improvement. However, because of the short experimental period and difficulty in subject control, increase values of the others did not show a significant difference. In other words, kinesio tape did not show maximizing the inspiratory muscle exercise effect to improve endurance and pulmonary function.

Background: Although there are improvements of clinical symtoms after bronchodilator inhalation in COPD patients, it has been noted that there was no increase of $FEV_1$ in some cases. $FEV_1$ did not reflect precisely the improvement of ventilatory mechanics after bronchodilator inhalation in these COPD patients. The main pathophysiology of COPD is obstruction of airway in expiratory phase but in result, the load of respiratory system is increased in inspiratory phase. Therefore the improvement of clinical symptoms after bronchodilator inhalation may be due to the decrease of inspiratory load. So we performed the study which investigated the effect of bronchodilator on inspiratory response of vetilatory mechanics in COPD patients. Methods: In 17 stable COPD patients, inspiratory and expiratory forced flow-volume curves were measured respectively before bronchodilator inhalation. 10mg of salbutamol solution was inhaled via jet nebulizer for 4 minutes. Forced expiratory and inspiratory flow-volume curves were measured again 15 minutes after bronchodilator inhalation. Results: $FEV_1$, FVC and $FEV_1$/FVC% were $0.92{\pm}0.34L$($38.3{\pm}14.9%$ predicted), $2.5{\pm}0.81L$($71.1{\pm}21.0%$ predicted) and $43.1{\pm}14.5%$ respectively before bronchodilator inhalation. The values of increase of $FEV_1$, FVC and PIF(Peak Inspiratory Flow) were $0.15{\pm}0.13L$(relative increase: 17.0%), $0.58{\pm}0.38\;L$(29.0%) and $1.0{\pm}0.56L$/sec(37.5%) respectively after bronchodilator inhalation. The increase of PIF was twice more than $FEV_1$ in average(p<0.001). The increase of PIF in these patients whose $FEV_1$ was not increased after bronchodilator inhalation were 35.0%, 44.0% and 55.5% respectively. Conclusion: The inspiratory parameter reflected improvement of ventilatory mechanics by inhaled bronchodilater better than expiratory parameters in COPD patients.

PURPOSE: The purpose of this study was to investigate the immediate effects of inspiratory muscle training on diaphragm movement and pulmonary function in healthy women. METHODS: The subjects of the study were 27 young women between ages 19 and 22 years who had no history of orthopedic damage for the last 6 months. The 27 participants were randomly selected and spontaneously participated and consented to the purpose of the study. This study measured diaphragm movement and pulmonary function under two different conditions, before and after inspiratory muscle training. Ultrasonography is appropriate for measuring diaphragm movement, and Pony Fx is appropriate to measure pulmonary function such as forced vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$), $FEV_1/FVC$ ratio, and peak expiratory flow (PEF) before and after inspiratory muscle training. Paired t-test with a significant level of .05 was used for statistical analysis. RESULTS: As a result, diaphragm movement significantly increases 1.45cm from before inspiratory muscle training (p<.05). Also, FVC, $FEV_1$, and FEP significantly increase 11.25%, 6.96%, and 8.18%, respectively, from before inspiratory muscle training (p<.05). CONCLUSION: The diaphragm movement and pulmonary function of the healthy women in this study were in stantly affected by inspiratory muscle training. From these results, we need to confirm effects of inspiratory muscle training on clinical patients such as pulmonary disease.

Purpose: The purpose of this study was to evaluate and compare the effects of inspiratory muscle training with chest expansion exercises on pulmonary function, maximal inspiratory pressure, and gait in individuals with stroke. Methods: The participants in this study included 36 stroke patients. These patients were randomly divided into three groups: an inspiratory muscle training (IMT) with chest expansion (CE) group (n=12), an IMT group (n=12), and a control group (n=12). Participants in the IMT with CE group underwent IMT and CE exercises 5 times per week for 30 minutes over 4 weeks, whereas those in the CE group and the control group received IMT and conventional physical therapy, respectively, for the same duration. The investigator measured the patients' pulmonary function, maximal inspiratory pressure, and gait endurance. Results: After the intervention, the change values for the forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), maximal inspiratory pressure (MIP), and six-minute walk test (6MWT) in the IMT with CE group and the control group were significantly greater than those of the control group (p<0.05). Similarly, after the intervention, the change values of the FVC, FEV1, PEF, MIP, and 6MWT in the IMT with CE group were significantly greater than those in the IMT group (p<0.05). Conclusion: These findings suggest that IMT with CE could be used to increase pulmonary function, maximal inspiratory pressure, and gait endurance in stroke patients.

Objective: The aim of this study is to explore how using inspiratory training affects the respiratory function and balance of stroke patients. We also plan to compare the results with a control group that does not receive the intervention. Design: A Randomized Controlled Trial Methods: In this study, 27 chronic stroke patients were randomly assigned to either a control group (n=14) or an experimental group (n=13). Both groups underwent six weeks of common interventions involving standard physiotherapy and treadmill training. Additionally, the experimental group received inspiratory training. Respiratory function and balance were evaluated using Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1), Maximal Inspiratory Pressure (MIP), Maximal Expiratory Pressure (MEP), Peak Expiratory Flow (PEF), Five times Sit-to-Stand (FTSTS), Seated Center of Pressure (S-COP), and Timed Up and Go (TUG) tests. Results: Respiratory function and balance were compared within each group before and after intervention. The experimental group, which received inspiratory training, showed significant improvements in FVC (0.26±0.18), FEV1 (0.35±0.32), MIP (11.54±12.39), PEF (1.12±1.52), and TUG (-3.39±2.45) compared to pre-intervention values (p<0.05). When comparing changes between groups post-intervention, the experimental group demonstrated significant increases in FVC, FEV1, MIP, PEF, and TUG compared to the control group (p<0.05). However, there were no significant differences in MEP, FTSTS, and S-COP. Conclusions: The results of this study indicate a positive effect of inspiratory training on chronic stroke patients. These findings suggest that with further research involving a larger sample size and enhanced intervention methods, inspiratory training could be employed positively in the rehabilitation of stroke patients.

PURPOSE: This study was conducted to analyze the effects of virtual reality inspiratory muscle training and conventional inspiratory muscle training on diaphragm movement and pulmonary function in patients with thoracic restriction. METHODS: This study measured diaphragm movement, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), and thoracic mobility (upper, middle, and lower trunk) under two different conditions. Forty young women between 19 and 24 years of age who had no history of orthopedic symptoms for the last 6 months were divided into experimental and control groups. The experimental group performed virtual reality inspiratory muscle training and diaphragm breathing, and the control group performed conventional inspiratory muscle training and diaphragm breathing. RESULTS: The control group showed a significant increase in all dependent variables except for lower trunk mobility and PEF. The experimental group showed a significant increase in all dependent variables except for lower trunk mobility. Particularly, the experimental group showed significant increases in diaphragm movement (p<.05), FVC (p<.05), FEV1 (p<.05), and PEF (p<.05) relative to the control group. CONCLUSION: We recommend inspiratory muscle training with a virtual reality program over conventional training to improve diaphragm movement and pulmonary function in patients with thoracic restriction.

PURPOSE: The purpose of this study was to examine the effects of respiratory muscle training on respiratory function, respiratory muscle strength, and cough capacity in stroke patients. METHODS: This study used a nonequivalent control group pre-post test design. We recruited thirty-four stroke patients(16male, 18female), who were assigned to intervention (n=17), or control (n=17) groups. Both groups participated in a conventional stroke rehabilitation program, with the intervention groups also receiving respiratory muscle training 20 minutes a day, three times a week, for 4 weeks. Respiratory function (forced vital capacity) and respiratory muscle strength (maximal inspiratory pressure, maximal expiratory pressure) were assessed by spirometry. Cough capacity (peak expiratory flow) was assessed using a peak flow meter. The collected data were analyzed by independent and paired t-tests. RESULTS: The intervention group showed a significant increase in the forced vital capacity (FVC), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP) and peak expiratory flow (PEF) at the end of the program, while the control group showed no significant changes. CONCLUSION: This study showed that respiratory muscle training increased respiratory function, respiratory muscle strength, and cough capacity in stroke patients and prevented a decrease in cough capacity. These findings suggest that respiratory muscle training effect on respiratory function, respiratory muscle strength and cough capacity for rehabilitation in patients with stroke.
