ABSTRACT
Age-related loss of muscle strength in expiratory muscles with reductions in elastic recoil of the lungs and chest wall compliance may compromise necessary lung pressure for a variety of speech tasks. This study examined the effects of a 4-week expiratory muscle strength training(EMST) program in 18 healthy elderly adults as measured by maximum expiratory pressure(MEP) as well as intraoral pressure(PO) for speech. MEP as well as PO at the softest possible intensity level, phonation threshold pressure(Pth), and the loudest possible intensity level(PL) were measured. The results indicated significant improvements in MEP and PO at the loudest possible intensity level. This study supported that EMST may be an effective way to change or compensate for age-related neuromuscular deterioration in expiratory muscles, which can be utilized to increase vocal intensity.
