Ventilatory Function and Exercise Capacity Response to Inspiratory Muscle Training in Interstitial Lung Disease Patients

Inspiratory muscle training (IMT) has been described as one of the components of the treatment of chronic lung conditions such as obstructive and restrictive lung diseases. Although the number of studies showing results of IMT in patients with interstitial lung disease (ILD) is scarce when compared with studies in patients with COPD, evidence points to benefits of IMT in this population. This scoping review aimed to explore the role and the rationale of IMT in patients with ILD and to gather recent evidence on the effects of IMT in this population. The studies included in this review showed improvements in respiratory muscle function, quality of life, exercise capacity and dyspnea after ILD patients participated in programs that included stand-alone IMT or combined with pulmonary rehabilitation. There is still a gap in the literature to allow a clear conclusion on the indications of IMT as part of ILD treatment because of poor research design and small numbers of participants. Therefore, although IMT seems to have a positive effect in patients with ILD, current evidence prevents us from drawing a definite conclusion. Further studies need to be conducted using better research methodology to demonstrate and confirm the positive effects of IMT.

Abstract Background and Purpose. Previous investigations have demonstrated that a regimen of high-intensity inspiratory muscle training (IMT) resulted in changes in ventilatory function and exercise capacity in patients with chronic lung disease, although the effect of high-intensity IMT in subjects who are healthy is yet to be determined. The purpose of this study, therefore, was to examine whether high-intensity IMT resulted in changes in ventilatory function and exercise capacity in subjects who were healthy. Subjects. Twenty subjects were randomly assigned to 2 groups. Methods. The training group completed an 8-week program of IMT set at 80% of maximal effort. The control group did not participate in any form of training. Baseline and posttraining measures of body composition, pulmonary function, inspiratory muscle function (including maximal and sustained maximal inspiratory pressures [MIP and SMIP]), relaxed and contracted diaphragm thickness and thickening ratio (Tdi.rel, Tdi.cont, and TR), and exercise capacity were determined. Results. The training group demonstrated significant increases in MIP, SMIP, Tdi.cont, TR, VC, total lung capacity, and exercise capacity compared with the control group, which demonstrated no change from baseline measurements at 8 weeks. Discussion and Conclusion. The findings of this study suggest that high-intensity IMT results in increased contracted diaphragm thickness and increased lung volumes and exercise capacity in people who are healthy.

Recreational Runners

Background: Running is a new trend of recreational sports in Indonesia. About 70% of recreational runners have difficulty in improving exercise capacity due to exercise-related transient abdominal pain (ETAP), caused by fatigue of the diaphragmatic muscles. Previous studies have shown that various training methods may increase diaphragmatic muscle strength and endurance, for example, inspiratory muscle training (IMT). Unfortunately, improvement of inspiratory muscle strength and endurance after exercise and IMT are still varies. Therefore, other methods are needed to optimize the effect of IMT. Application of the elastic taping on thoracic wall during exercise allows the inspiratory muscles to contract optimally which might improve functional capacity.Aim: To assess the effect of elastic taping on inspiratory muscle training using the pressure threshold IMT, in increasing the functional exercise capacity of recreational runners. Functional capacity was measured based on VO2max value, rating of perceived breathlessness (RPB) and rating of perceived exertion (RPE).Methods: an experimental study involved 14 nonsmoker recreational runners, ages 20-40 years, at Outpatient Clinic of Physical Medicine and Rehabilitation Department of Dr. Soetomo Hospital Surabaya. Subjects were divided into two groups (pressure threshold IMT with and without elastic taping groups), which were observed for four weeks. IMT was done five times a week, twice a day, with 30 repetitions, and 60% resistance 30 RM using Respironics®. Elastic taping Leukotape® was applied on the first until fifth day in each IMT sessions. The running exercises were done three times a week with EnMill® Treadmill ETB-03195 with a speed of 4.5 mph and 0% inclination. RBP, RPE and VO2max were measured using Borg Dyspneu scale, Borg Scale, and Bruce Treadmill Protocol test, respectively, before the first exercise and after 4 weeks of exercise.Results: There were an improvement of functional exercise capacity in both groups which were marked with a decline of RPB and RPE and increase of VO2max (p values < 0.05). However, there were no significant differences in the decrease of RPB and RPE and an increase of VO2max between groups (p values of were 0.31, 0.83, and 0.13, respectively). The effect of the elastic taping (r2 = 0.99) was not reflected in the differences of RPB, RPE and increasing VO2max.Conclusion: Inspiratory muscle training using pressure threshold IMT with or without the elastic taping for four weeks can improve exercise capacity of recreational runners.
