在吞咽过程中，舌头在通过口腔输送液体和食物的压力的产生中起着关键作用。最近的研究表明，健康成年人的舌力随着年龄的增长而下降。然而，吞咽时产生的舌压是否会发生与年龄相关的变化仍不清楚。在这方面，以前的文献没有明确地探讨任务对舌压幅度随年龄的明显差异的影响。此外，可归因于个体力量差异的差异，与年龄无关，尚未明确阐明。在这项研究中，我们的目标是澄清老年人在最大等长、唾液吞咽和水吞咽任务中是否降低了舌腭部压力，同时控制了个体力量的差异。数据来自40名健康的年轻人(40岁以下)和38名健康的成年人(60岁以上)。作为一个群体，成熟参与者的最大等长压力(MIP)显著较低。吞咽压力因任务的不同而有显著差异，唾液燕子的吞咽压力高于水燕。在吞咽压力方面，年龄组之间没有差异。将MIP作为吞咽压力分析的协变量，在老年参与者组中显示了强度和吞咽压力之间的显著相关性。只有在模型中考虑力量时，年龄组差异才明显，这表明与年龄相关的明显差异实际上是由力量差异解释的，在健康的老年人中，力量差异往往更低。我们的结果没有证据表明吞咽压力的独立差异可归因于年龄。
The tongue plays a key role in the generation of pressures for transporting liquids and foods through the mouth in swallowing. Recent studies suggest that there is an age-related decline in tongue strength in healthy adults. However, whether age-related changes occur in tongue pressures generated for the purpose of swallowing remains unclear. Prior literature in this regard does not clearly explore the influence of task on apparent age-related differences in tongue pressure amplitudes. Furthermore, differences attributable to variations across individuals in strength, independent of age, have not clearly been elucidated. In this study, our goal was to clarify whether older adults have reduced tongue-palate pressures during maximum isometric, saliva swallowing, and water swallowing tasks, while controlling for individual variations in strength. Data were collected from 40 healthy younger adults (under age 40) and 38 healthy mature adults (over age 60). As a group, the mature participants had significantly lower maximum isometric pressures (MIPs). Swallowing pressures differed significantly by task, with higher pressures seen in saliva swallows than in water swallows. Age-group differences were not seen in swallowing pressures. Consideration of MIP as a covariate in the analysis of swallowing pressures revealed significant correlations between strength and swallowing pressures in the older participant group. Age-group differences were evident only when strength was considered in the model, suggesting that apparent age-related differences are, in fact, explained by differences in strength, which tends to be lower in healthy older adults. Our results show no evidence of independent differences in swallowing pressures attributable to age.
