Abstract
- Limb and respiratory muscle (diaphragm) strength and fatiguability have been extensively studied in man and are known to vary with age and sex. However, in contrast to limb muscles and the diaphragm, force and fatiguability characteristics have not been studied in upper airway muscles. This study examines the hypotheses that tongue protrusion strength or fatiguability, determined by the properties of the intrinsic muscles and genioglossus, may change with age and may be reduced in males compared to females. A force transducer was used to compare maximal tongue protrusion force (Fmax) and fatiguability in 81 males and 86 females matched for age (mean+/-SD, 43+/-19 yrs, 42+/-19 yrs, respectively). Fatiguability indices were based on the time that subjects could maintain 50% of Fmax. Fmax declined with age in both males (r=-0.57, p
