IMT With Behavioral Therapy In A Case Of A Rower With Presumed Exercise-Induced Paradoxical Vocal-Fold Dysfunction

“Paradoxical vocal fold dysfunction (PVFD) with high effort exercise can result in disruptions to ventilation, dyspnea, inspiratory stridor, elevated heart rate, and syncope. This single subject study experimentally tested an inspiratory muscle strength training (IMST) program with behavioral therapy on a 15-year-old male crew member.”

Conclusion:

“Outcome included successful competition with his high-school crew team, a task he was previously unable to complete. Discussion focuses on IMST combined with traditional approaches of voice therapy for treating PVFD.”

Inspiratory Muscle Training In Exercise-Induced Paradoxical Vocal Fold Motion

“The purpose of the study was to determine if inspiratory muscle training (IMT) would result in increased inspiratory muscle strength, reduced perception of exertional dyspnea, and improved measures of maximal exercise effort in an athlete with exercise-induced paradoxical vocal fold motion (PVFM).”

Conclusion:

“The findings suggest that IMT may be a promising treatment approach for athletes with exercise-induced PVFM.”

Effect Of Specific Inspiratory Muscle Warm-Up On Intense Intermittent Run To Exhaustion

“The effects of inspiratory muscle (IM) warm-up on the maximum dynamic IM function and the maximum repetitions of 20-m shuttle run (Ex) in the Yo-Yo intermittent recovery test were examined.”

Conclusion:

“Findings suggested that the specific IM warm-up in IMW may entail reduction in breathlessness sensation, partly attributable to the enhancement of dynamic IM functions, in subsequent exhaustive intermittent run and, in turn, improve the exercise tolerance.”

Therefore POWERbreathe Inspiratory Muscle Training can effectively be used to:

  • Warm-up the breathing muscles prior to rehearsal or performance

Specific Respiratory Warm-up Improves Rowing Performance And Exertional Dyspnea

“The purpose of this study was a) to compare the effect of three different warm-up protocols upon rowing performance and perception of dyspnea, and b) to identify the functional significance of a respiratory warm-up.”

Conclusion:

“These data suggest that a combination of a respiratory warm-up protocol together with a specific rowing warm-up is more effective than a specific rowing warm-up or a submaximal warm-up alone as a preparation for rowing performance.”

Therefore POWERbreathe Inspiratory Muscle Training can effectively be used to:

  • Warm-up the breathing muscles prior to rehearsal or performance

Laryngeal Movements During Inspiratory Muscle Training In Healthy Subjects

“Inspiratory muscle training (IMT) has been used to treat patients with exercise-induced vocal cord dysfunction (VCD); the theoretical basis being the close relationship between the diaphragm and the posterior cricoarytenoid muscle, which is the main abductor of the larynx. Before launching a treatment protocol in patients with VCD, we aimed to substantiate this theory by performing laryngoscopy in healthy subjects during standardized IMT programs.”

Conclusion:

“IMT can produce laryngeal abduction in healthy subjects, and training programs may conceivably contribute positively in patients suffering from laryngeal adduction during exercise. Individual response patterns varied between subjects and individualized programs seem crucial for effect. Use of high resistances seemed to be counterproductive.”

Therefore POWERbreathe Inspiratory Muscle Training:

  • May affect the intrinsic laryngeal muscles which control the action of the larynx

Effect of High-Intensity Inspiratory Muscle Training on Lung Volumes, Diaphragm Thickness, and Exercise Capacity in Subjects Who Are Healthy

“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.”

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.”

Therefore POWERbreathe Inspiratory Muscle Training can effectively be used to:

  • Enhance the ability to inflate the lungs (take deeper breaths)

Effects Of Changes In Inspiratory Muscle Strength On The Sensation Of Respiratory Force

“The sensation of respiratory muscle force was compared in seven normal subjects before and after inspiratory muscle strength training.”

Conclusion:

“Results suggest that the sensation of respiratory muscle force reflects the proportion of the maximum force utilized in breathing and may be based on the level of respiratory motor command signals.”

Therefore POWERbreathe Inspiratory Muscle Training can effectively be used to:

  • Enhance the ability to control the breath
  • Enhance the ability to sustain forceful breathing (breathing does not become fatigued)
