‘Inspiratory Muscles Strength Training in Recreational Athletes’ published in Revue Des Maladies Respiratoires (Respiratory Disease Review)
MedAtletic, POWERbreathe distributors in France, brought this recently published article to our attention, as POWERbreathe had been used in the research.
Summary
Introduction. — Respiratory muscles strength and endurance influence athletic performance. Besides conventional spirometry, sniff test, inspiratory and expiratory maximal pressures can directly assess respiratory muscle strength. Respiratory muscles can be trained through a device offering inspiratory and expiratory resistance.
Methods. — Nineteen subjects aged 18 to 30 years and practicing leisure sport trained inspiratory muscles on Powerbreathe® for eight weeks. Resistance was set at 85% of maximal inspiratory pressure determined during a preliminary session. Evaluation was made through voluntary and non-invasive methods on Macro 5000® (PI max, PE max and sniff test).
Results. — An increase of 21.77% of the maximum inspiratory pressure, 17% of the maximum expiratory pressure and 18% of the sniff test are recorded after eight weeks of training.
Conclusions. — A specific training of inspiratory muscles (Powerbreathe® Sports performance) increases the power of these muscles (voluntary and non-invasive tests). © 2011 SPLF. Published by Elsevier Masson SAS. AU rights reserved.
