 While several studies have suggested that the loss of motor units with increasing age results in the inability to control muscular power, the ability to control power in the tongue remains unknown. The objective of this study was therefore to investigate the functional ability to control power in the tongue. The study involved 15 healthy younger adults (27.1±2.6 years) and 12 healthy older adults (76.0±3.0 years). In each participant, tongue pressure (100%, 80%, 60%, 40%, 20%) was monitored with a tongue pressure measurement device. Both the younger and older age groups could control tongue pressure. Furthermore, the data showed that healthy younger adults exhibited significantly higher maximum tongue pressure than healthy older adults. Schwarz's earlier report stated that there are no age-associated changes in terms of the number of hypoglossal motor neurons. Thus, our present results indicate that healthy older adults maintain the ability to control tongue power.
