Μάσκες Περιορισμού Αναπνοής Και Προπόνηση - Τι Λένε Οι Μελέτες;
Μια σχετικα νεα μοδα στο χωρο ειναι οι μασκες περιορισμου αναπνοων που υποσχονται να βελτιωσουν την αποδοση στις προπονησεις.
Η παρακατω μελετη απο το Journal of Strength and Conditioning Research ειχε ως σκοπο να προσδιορισει την επιδραση της περιοριστικης μασκας αναπνοης στη μυικη αποδοση, στην αιμοδυναμικη και στις μεταβλητες στρες, που παρατηρηθηκαν κατα τη διαρκεια ασκησης με αντιστασεις στα κατω ακρα.
Το συμπερασμα ηταν πως η μασκα περιορισμου αναπνοων ειχε αρνητκη επιδραση στον αριθμο επαναληψεων που ολοκληρωθηκαν κατα τη διαρκεια ασκησης με αντιστασεις στο κατω σωμα.

Restrictive breathing mask reduces repetitions to failure during a session of lower-body resistance exercise. J Strength Cond Res XX(X): 000-000, 2018- The purpose of this study was to determine the effect of restrictive breathing mask (RBM) on muscle performance, hemodynamic, and perceived stress variables during a session of lower-body resistance exercise. In a crossover design, 10 participants performed 2 separate testing sessions, RBM and no mask, consisting of squat, leg press, and leg extension. The paired-samples t-test was used for session rating of perceived exertion (S-RPE), perceived stress before and after, heart rate (HR), pulse oximetry, and a 2 ? 4 (session [mask, no mask] ? time [squat exercise, leg press exercise, leg extension exercise, total resistance exercise session]) factorial analysis of variance with repeated measures (p ? 0.05). A significant decrease was found in total repetitions during the RBM condition (p < 0.01). A majority of the decrease in repetitions to failure occurred in the squat (p < 0.05) and in the leg press (p < 0.01), whereas no difference was observed in leg extension (p = 0.214). A significant increase was observed in S-RPE during the RBM session (p < 0.01). A significant increase was found in prestress (p < 0.01) and poststress (p = 0.01) in the RBM session. No significant difference existed for HR between exercise sessions (p = 0.08). A significant decrease existed in pulse oximetry during the RBM session (p < 0.01). The use of an RBM had a negative effect on the number of repetitions completed during an acute session of lower-body resistance training.
