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.

Effects Of Inspiratory Muscle Training On Time-Trial Performance In Trained Cyclists

“We evaluated the effects of specific inspiratory muscle training on simulated time-trial performance in trained cyclists.”

Conclusion:

“Results support evidence that specific inspiratory muscle training attenuates the perceptual response to maximal incremental exercise. Furthermore, they provide evidence of performance enhancements in competitive cyclists after inspiratory muscle training.”
