Introduction: The purpose of this study was to investigate the effects of special exercises TRAINING protocol of the INSPIRATORY MUSCLEs on the vital capacity.Materials and Methods: 62 normal subjects' female students without any respiratory disease history participated in the study. At first, all subjects participated in a familiarization session to learn a correct pattern of ventilation and then the vital capacity was measured by spirometer. The vital capacity (VC) and %80 of maximum voluntary contraction (MVC) force of INSPIRATORY MUSCLEs were assessed and monitored by computerized spirometry machine to the subjects .The subjects were randomly assigned in two control (n=30) and experimental (n=32) groups. Subjects in the experimental group were asked to perform a daily INSPIRATORY exercise protocol including 6 inspiration MUSCLE contraction (using %80 of MVC). Each contraction was separated with a rest time from the next contraction. The first rest time was 60 seconds and second rest time was 45 second and so on 30, 15, 10 seconds. The control group did not performance any other form of exercises. The VC was recorded at the end of each week in both groups and compared to the base line by paired t Test. Results: The results revealed that there are significant increase in the VC at the end of the fifth week (P<0.001) and tenth week (P<0.001) in the experimental group while no significant change was found in the control group. These findings show that the average changes of vital capacity in end of 10 weeks increased significantly in INSPIRATORY MUSCLE TRAINING group rather than control group.Conclusion: INSPIRATORY MUSCLE TRAINING is a suitable method to increase the ventilation vital capacity and further study is needed to investigate the stability of the increased VC by this method and also the effect of this INSPIRATORY TRAINING method on the patient with respiratory disease.

Background: Hyper-kyphosis is one of the most common malalignments in adolescent boys and can affect their breathing. INSPIRATORY MUSCLE TRAINING (IMT) may improve the function of the respiratory MUSCLEs in adolescents and may influence their skeletal structure as well. So, this study aimed to examine the effects of INSPIRATORY MUSCLE TRAINING on the thoracic spine curve, INSPIRATORY volume and cardio-respiratory endurance in hyperkyphotic boys Methods: This study was a semi experimentally in design, pre and post-test design with a control group. Twenty-two 12-15 boys, with thoracic spine curve more than 49 degrees were randomly divided into control and experimental groups. Both groups performed the same corrective exercise for hyper-kyphosis, the experimental group also performed INSPIRATORY MUSCLE TRAINING five days a week using the power breathing device, based on the TRAINING protocol. Both groups were evaluated before and after 12 weeks of TRAINING in terms of the thoracic spine curve, INSPIRATORY volume, S-index, PIF, and cardiorespiratory endurance. Results: The data analysis showed that the thoracic spine curve decreased significantly in the IMT group (Pvalue=0. 025). The IMT group showed significantly increase in INSPIRATORY S-index (T=4. 058, Pvalue=0. 002), PIF (T=4. 06, Pvalue=0. 002) and cardio-respiratory endurance (T=2. 62, Pvalue=0. 050) at posttest in compare to control group. Conclusions: Based on the study findings, it can be concluded that respiratory MUSCLE strengthening alone may not be by itself sufficient for the improvement of Hyper-kyphosis, and corrective exercises can also be recommended along with it.

Background and Objective: Chronic obstructive pulmonary disease (COPD) obviously disturbs quality of life by reducing exercise tolerance, dyspnea and fatigue. The aim of the present study was to investigate the effects of INSPIRATORY MUSCLE TRAINING on improving the quality of life in COPD patients.Methods: This randomized controlled trial consisted of 30 patients (27 males, 3 females) with mild to very severe COPD referred to the specialist pulmonary clinic. The patients were randomly divided into two equal groups. TRAINING was performed with respivol flow-volumetric INSPIRATORY exerciser.The IMT group trained 8 weeks (21 minutes/day for 6 days/week). The quality of life was evaluated by St George questionnaire at the beginning and end of 8 weeks of INSPIRATORY MUSCLE TRAINING.Result: At the end of TRAINING, a significant improvement in total score of quality of life was observed in IMT group versus control group (P<0.001). The 3 dimensions of quality of life include: activity (P<0.001) symptom (P=0.001) and impact (P<0.001) showed statistically significant improvement in comparison with control group.Conclusion: The findings of this study demonstrate that INSPIRATORY MUSCLE TRAINING has beneficial effects on quality of life in COPD patients.

Introduction: The present study aimed to investigate the effects of INSPIRATORY MUSCLE TRAINING (IMT) on the spirometry parameters of patients with chronic obstructive pulmonary disease (COPD). Materials and methods. In this study, 60 men with COPD referring to Masih Daneshvari Hospital of Tehran were selected and randomly assigned to control (normal rehabilitation) and test (normal rehabilitation with IMT) groups. In addition to standard drug therapy, patients in the test group participated in a 4-week exercise therapy program (for sessions per week) consisting of strength TRAINING for the proximal MUSCLEs of the upper and lower extremities, aerobic exercises with treadmill, and IMT. The spirometry parameters including FEV1 and FVC were measured before and after the TRAINING period. The obtained data were statistically analyzed using the dependent t-test and analysis of covariance at the 0. 05 level of significance. Results: The results revealed that IMT significantly improved the FEV1 and FVC in patients with COPD (P<0. 05). In addition, the results showed that IMT was more effective than normal rehabilitation in improving the studied variables (P<0. 05). Conclusion: It can be generally concluded that respiratory and rehabilitation exercises with an emphasis on INSPIRATORY MUSCLEs strengthening can improve the spirometry parameters in patients with COPD. This suggests these patients should benefit from IMT programs.
