Abstract:
Objective To observe the immediate effects of the sustained forced-blowing exercise (SFBE) on the phonation function in young healthy people. Methods 43 young healthy people were asked to pronounce a longest /a/ in a comfortable situation within one breath for 3 times before and after SFBE. The sound files were analyzed with computer sound analysis system, with the parameters of mean maximum phonation time (MMPT), mean frequency (MF) and mean sound pressure level (MSPL). Results The MMPT and MSPL increased (P< 0.01) after SFBE. There was no significant difference in the MF (P>0.05) before and after SFBE. Conclusion The SFBE can improve the MPT and MSPL of the healthy people obviously, without affections on the MF.
