The Ideal

The fatigue of the respiratory muscles causes the so-called metabolic reflex or metaboreflex, resulting in vasoconstriction of the blood vessels in the peripheral muscles, which leads to a decrease in respiratory performance. Training the respiratory muscles is a possible solution to avoid this type of impairment in intermittent sports. The objective of this systematic review was to evaluate the results obtained with inspiratory muscle training (IMT) in intermittent sports modalities, intending to determine whether its implementation would be adequate and useful in intermittent sports. A search in the Web of Science (WOS) and Scopus databases was conducted, following the Preferred Reporting Elements for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The methodological quality of the articles was assessed using the PEDro (Physiotherapy Evidence Database) scale. In conclusion, the introduction of specific devices of IMT seems to be a suitable method to improve performance in intermittent sports, mainly due to a reduction of the metaboreflex, fatigue sensation, and dyspnea. The ideal protocol would consist of a combination of acute and chronic treatment, and, even if IMT is done daily, the duration will not exceed one hour per week.

Clinical Benefits

BACKGROUND: Neuromuscular diseases are characterized by the compromise of respiratory muscles, thoracic ventilation, muscle strength and coughing capacity. Patients have low quality of life and increased morbidity and mortality mostly due to respiratory impairment. OBJECTIVE: To assess the benefits of adding inspiratory muscle training to neuromuscular patients’ treatment and their compliance to the approach. METHODS: We conducted a single-center prospective study with neuromuscular patients with decreased maximal inspiratory pressure. We developed an inspiratory muscle training protocol with three-month duration and once-daily training. The protocol had a progressive intensity that was individually tailored based on patients’ baseline characteristics and tolerance. We used Powerbreathe Medic Classic devices to perform the training. RESULTS: There were 21 patients who met the inclusion criteria and were enrolled in the study. Muscular dystrophy (n= 12, 57.3%) and amyotrophic lateral sclerosis (n= 4, 19%) were the most common diseases. After three months of training, patients increased their maximal inspiratory muscle pressure (p= 0.002) and peak cough flow (p= 0.011). Compliance to the protocol was 99 ± 5.5%. CONCLUSIONS: This protocol showed significant improvements on pulmonary muscles function and might be considered as an adjunct treatment to neuromuscular treatment. However, these positive results require larger further studies to validate the clinical benefits long-term.

Inspiratory Muscle Strength

Abstract Background: In ventilator-dependent ICU patients, inspiratory muscle training may improve inspiratory muscle strength and accelerate liberation from the ventilator, but optimal training parameters are yet to be established and little is known about the impact of inspiratory muscle training on quality of life or dyspnea. Thus we sough to ascertain whether inspiratory muscle training, commenced while ventilator-dependent, would improve outcomes for ICU patients invasively ventilated for 7 days or longer.Methods: In this randomized trial with assessor-blinding and intention-to-treat analysis, 70 participants (mechanically ventilated ≥7 days) were randomized to receive once- daily supervised high-intensity inspiratory muscle training with a mechanical threshold device in addition to usual care, or usual care (control). Primary outcomes were inspiratory muscle strength (maximum inspiratory pressure % predicted) and endurance (fatigue resistance index) at ventilator-liberation and 1 week later, and quality of life (SF-36v2, EQ-5D). Secondary outcomes included dyspnea, physical function, duration of ventilation and in-hospital mortality.Results: 33 participants were randomly allocated to the training group and 37 to control. There were no statistically significant differences in strength (maximum inspiratory pressure) (95% CI -7.4 to 14.0) or endurance (fatigue resistance index) (95% CI -0.003 to 0.436). Quality of life improved significantly more in the training group than control (EQ5D 17.2; 95% CI 1.3-33.0) (SF36-PCS 6.97; 96%CI 1.96-12.00). Only the training group demonstrated significant reductions in dyspnea (-1.5 at rest, -1.9 during exercise). There were no between-group differences in duration of ventilation or other measures. In-hospital mortality was higher in the control group than the training group (9 vs 4, 24% vs 12%, p=0.23).Conclusions: In ventilator-dependent patients, mechanical threshold loading inspiratory muscle training improves quality of life and dyspnea, even in the absence of strength improvements or acceleration of ventilator liberation.

The value of inspiratory muscle training (IMT) in pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) is unclear. The RIMTCORE (Routine Inspiratory Muscle Training within COPD Rehabilitation) randomised controlled trial examined the effectiveness of IMT added to pulmonary rehabilitation.In total, 611 COPD patients (Global Initiative for Chronic Obstructive Lung Disease stage II–IV) received a 3-week inpatient pulmonary rehabilitation, of which 602 patients were included in the intention-to-treat analyses. The intervention group (n=300) received highly intensive IMT and the control group (n=302) received sham IMT. The primary outcome was maximal inspiratory pressure (PImax). The secondary outcomes were 6-min walk distance, dyspnoea, quality of life and lung function. Outcomes were assessed pre- and post-pulmonary rehabilitation. ANCOVA was used.The intervention group showed higher effects in PImax (p<0.001) and forced inspiratory volume in 1 s (p=0.013). All other outcomes in both study groups improved significantly, but without further between-group differences. Sex and pulmonary rehabilitation admission shortly after hospitalisation modified quality of life effects.IMT as an add-on to a 3-week pulmonary rehabilitation improves inspiratory muscle strength, but does not provide additional benefits in terms of exercise capacity, quality of life or dyspnoea. A general recommendation for COPD patients to add IMT to a 3-week pulmonary rehabilitation cannot be made.
