Why the study?
The study was conducted to determine the effects of limiting lower rib cage lateral expansion on maximal inspiratory and expiratory pressures and abdominal muscle activity during maximal breathing in healthy subjects.
Does lower rib expansion limitation using a non-elastic belt affect maximal respiratory pressure and abdominal muscle activity during maximal breathing in healthy male subjects?
Does lower rib expansion limitation using a non-elastic belt affect maximal respiratory pressure and abdominal muscle activity during maximal breathing in healthy male subjects?
Limiting lower rib expansion with a non-elastic belt during maximal breathing in healthy men does not change maximal respiratory pressures but decreases right external oblique muscle activity during forced exhalation.
Belt use does not alter maximal pressures in healthy men; leaves open effects of rib restriction on breathing mechanics in disease.
The aim of this study was to determine the effects of lower rib cage lateral expansion limitation on the maximal inspiratory and expiratory pressures and on abdominal muscle activity during maximal respiratory breathing in healthy subjects. Methods: Fifteen healthy male subjects voluntarily participated in this cross-sectional study. During maximal breathing, maximal inspiratory and expiratory pressures were measured, and abdominal muscle activity was determined with using surface electromyography. Also, the measurement was repeated with using a non-elastic belt to the lower rib cage for limiting of lateral expansion. A Wilcoxon signed-rank test was performed for obtaining the statistical difference with a significance level of 0.05.
