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

‘Functional’ Inspiratory And Core Muscle Training Enhances Running Performance And Economy

“This study compared the effects of two 6-week high-intensity interval training interventions. Under the control condition, only interval training was undertaken, whilst under the intervention condition, interval training sessions were followed immediately by core training, which was combined with simultaneous inspiratory muscle training – ‘functional’ IMT.”

Conclusion:

“Findings suggest that the addition of inspiratory-loaded core conditioning into a high-intensity interval training program augments the influence of the interval program upon endurance running performance, and that this may be underpinned by an improvement in running economy.”

The Effect Of Inspiratory Muscle Training On High-Intensity, Intermittent Running Performance To Exhaustion

“This studied the effects of inspiratory muscle training (IMT) on maximal 20m shuttle run performance during Yo-Yo intermittent recovery test and on the physiological and perceptual responses to the running test were examined.“

Conclusion:

“Findings suggest that although both inspiratory muscle training and warm-up improve the tolerance of intense intermittent exercise, the underlying mechanisms may be different.”

Occurrence of Core Muscle Fatigue During High-Intensity Running Exercise and its Limitation to Performance

“The purpose of this study was to investigate the occurrence of core muscle fatigue during high-intensity running exercise and its limitation to exercise performance. A secondary aim was to investigate whether respiratory muscle work performed during intense running periods, would contribute to core muscle fatigue.”

Conclusion:

“Core muscle function in endurance runners subsequent to intense running to exhaustion was impaired with fatigue. With the preceded core muscle fatigue workout, the endurance capacity for performing intense running was reduced. In mimicking the respiratory responses recorded during intense running while the runners were standing upright and free from whole-body exercise, core muscle function decreased.

Specific Inspiratory Muscle Warm-Up Enhances Badminton Footwork Performance

For this study “the effects of inspiratory muscle warm-up on inspiratory muscle function and on the maximum distance covered in a subsequent incremental badminton-footwork test were examined.”

Conclusion:

“Findings suggest that the inspiratory mucsle-specific warm-up improved footwork performance in the subsequent maximum incremental badminton-footwork test. The improved footwork was partly attributable to the reduced breathless sensation resulting from the enhanced inspiratory mucsle function, whereas the contribution of the concomitant reduction in blood lactate accumulation was relatively minor.

Abstract:

“This study investigated the occurrence of core muscle fatigue during high-intensity running exercise and its limitation to exercise performance. A secondary aim was to investigate whether respiratory muscle work performed during intense running periods, would contribute to core muscle fatigue.”

Results:

“The results suggest that a high-intensity maximum run may induce core muscle fatigue in runners. The core muscle fatigue, which may be partly attributed to the corresponding respiratory work, may limit their running endurance. Inspiratory muscle function appears to be essential for core stabilization during the intense running.”

Conclusion:

Core muscle function in endurance runners subsequent to intense running to exhaustion was impaired with fatigue. With the preceded core muscle fatigue workout, the endurance capacity for performing intense running was reduced. In mimicking the respiratory responses recorded during intense running while the runners were standing upright and free from whole-body exercise, core muscle function decreased.

Key points:

  • A high-intensity maximum run may induce core muscle fatigue in runners. The core muscle fatigue, which may be partly attributed to the corresponding respiratory work, may limit their running endurance.
  • In support of previous notion, inspiratory muscles may share the work of core stabilization during intense exercise, while simultaneously increasing the demand for breathing.
  • Inspiratory muscle training incorporated into a running specific-core training regime potentially enhances the training effect on the core muscles in a functional manner to deal with the challenges faced during intense exercise.
