Alterations In Maximal Inspiratory Mouth Pressure During A 400m Maximum Effort Front-Crawl Swimming Trial

“The aim of this study was to examine the changes of maximal inspiratory mouth pressure (PImax) during a 400-m front crawl swimming trial.”

Conclusion:

“Results indicated that during a maximum effort of 400-m front crawl, the reduction of inspiratory muscle strength occurs after 300-m. This should be considered for competitive swimming training by implementing swim race distance-specific respiratory muscle training.”

Influence Of Different Breathing Frequencies On Severity Of Inspiratory Muscle Fatigue Induced By High-Intensity Front Crawl Swimming

“The aim of this study was to assess the influence of two different breathing frequencies on the magnitude of inspiratory muscle fatigue after high-intensity front crawl swimming.”

Conclusion:

“Data suggested that there is significant global inspiratory muscle fatigue after high-intensity swimming. Inspiratory muscle fatigue is, however, greater when breathing frequency is reduced during high-intensity front crawl swimming. Respiratory muscle training should be used to improve respiratory muscle strength and endurance in swimmers.”

Inspiratory Muscle Training Improves Shuttle Run Performance in Healthy Subjects

“The purpose of this study was to assess the use of computer-generated fixed-load incremental Respiratory Muscle Training (RMT) produced by the performance of repeated sustained sub-maximal inspiratory efforts with progressively reduced recovery times in healthy volunteers.”

Conclusion:

“Incremental respiratory endurance-based respiratory muscle training set at 80% of peak through range increases respiratory muscle strength, single-breath work capacity and respiratory muscle endurance and that these improvements result in reduced levels of breathlessness, an increase in predicted VO2 max and a perceived improvement in sports performance.”

Inspiratory Muscles Can Be Trained To Increase Strength Or Endurance

“This study examined whether resistive loading can train the inspiratory muscles differentially.”

Conclusion:

“Results demonstrate that pressure threshold resistive inspiratory muscle training can be utilised to train specifically for improvements in strength or endurance and that the improvements are maintained well post-training.”
