Changes In Respiratory Muscle And Lung Function Following Marathon Running In Man

“Respiratory muscle fatigue has been reported following short bouts of high-intensity exercise, and prolonged, moderate-intensity exercise… However, links to functionally relevant outcomes such as breathing effort have been lacking. This study examined dyspnoea and leg fatigue during a treadmill marathon in nine experienced runners.”


“Results confirm that prolonged moderate-intensity exercise induces inspiratory muscle fatigue. Furthermore, they suggest that the relative intensity of inspiratory muscle work during exercise makes some contribution to leg fatigue.”

Congratulations to Risa “Licha” Suzuki – POWERbreathe sponsored athlete in the Tokyo Marathon 2012

The Tokyo Marathon for elite runners is the largest marathon race in Asia took place on 26th February 2012.

Risa, who was sponsored with a POWERbreathe by Entry Japan, POWERbreathe distributors based in Tokyo, was placed a fantastic 10th out of all the Japanese female runners.

What makes this even more amazing is that Risa isn’t a member of a professional team and up until a year ago worked in an office.

Risa’s time was an incredible 2:43 (approximately) and she still had more to give at the end of the Marathon.

Everyone at POWERbreathe would like to congratulate Risa on this phenomenal result, and thank you to Dan Stakoe at Entry Japan for sharing this news with us.  If you’d like to congratulate Risa too, please leave a comment here.
