The Influence Of Respiratory Muscle Training Upon Intermittent Exercise Performance

“The purpose of this study was to determine the effect of respiratory muscle training on intermittent exercise performance, respiratory muscle strength, respiratory muscle fatigue, and dyspnea in soccer athletes.”


“Respiratory Muscle Training improved intermittent exercise performance in these soccer athletes. The mechanisms by which RMT improves performance warrant further study.”

Respiratory Muscle Power And The Slow Component Of O2 Uptake

“The slow component of O2 uptake represents a progressive decline in work efficiency during strenuous, constant work rate cycling. Although most of this “excess” O2 uptake can be explained by factors intrinsic to the exercising muscles, it has been proposed that respiratory muscle work rate may also contribute to the O2 uptake response.”


“This investigation supports the thesis that the energetic contribution from respiratory muscles to the O2 uptake amplitude is disproportionately higher during severe-intensity exercise compared with that during heavy-intensity exercise.”

Locomotor And Diaphragm Muscle Fatigue In Endurance Athletes Performing Time-Trials Of Different Durations

“Fatigue in leg muscles might differ between running and cycling due to inherent differences in muscle activation patterns. Moreover, postural demand placed upon the diaphragm during running could augment the development of diaphragm fatigue.”


“Diaphragm fatigue likely resulted from the large ventilatory load which is characteristic for both exercise modalities and which was higher in 15TTs than in 30TTs (+27 %, p < 0.01) while postural demand appears to be of less importance.”

Inspiratory Resistive Loading After All-Out Exercise Improves Subsequent Performance

Previous studies have shown that post-exercise inspiratory resistive loading reduces blood lactate. In this study, we tested the hypothesis that inspiratory resistive loading during recovery could improve subsequent exercise performance.


“Inspiratory resistive loading during recovery from all-out maximal-intensity exercise decreases blood lactate and perception of leg effort with beneficial effects on peak and mean power on subsequent supra-maximal exercise in healthy males. Our results provide rationale for using post-exercise inspiratory resistive loading as an ergogenic aid and future studies should be conducted to better evaluate the mechanisms responsible for this effect.”
