Abstract: It has been reported that using of the spine mat increases chest expansion, inspiratory capacity (IC) and maximum inspiratory mouth pressure (PImax). However, no changes were observed in other respiratory functions and the respiratory muscle strength. The purpose of this study was to clarify the effects of pursed-lip breathing lying on the spine mat to the respiratory function and respiratory muscle strength. Forty-two adult male participants were assigned to two groups; an intervention group (IG group) of 21 participants who performed pursed-lip breathing on top of a spine mat and a control group (CG group) of 21 participants who performed pursed-lip breathing only. The intervention period was 5 days, and the respiratory features evaluated were chest expansion, respiratory function, respiratory muscle strength, and spinal alignment. A significant increase between the Pretest and the Posttest in chest expansion at the circumference of the axilla level, of the xiphoid process level and of the 10th rib level was observed only in IG group. For the respiratory function and the respiratory muscle strength, intervention group showed significant increases in percentage of vital capacity (%VC), tidal volume (TV), PImax, and maximum expiratory mouth pressure (PEmax). In the control group, only the TV indicated a significant increase. Regarding changes before and after the intervention, the intervention group showed significantly higher PImax and PEmax than the control group. No significant difference in spinal alignment was observed between the two groups. These results showed that pursed-lip breathing lying on the spine mat would increase the PImax, PEmax and the chest expansion.
