背景。人们普遍认为年龄相关的变化发生在随意肌。对握力和衰老的研究表明，握力随着年龄的增长而下降；然而，关于舌头功能的数据很少。本研究的目的是确定年龄增长与舌头强度和耐力的关系。一个压力传感器，爱荷华口腔性能仪，被用来测量手和舌头的最大力量和耐力。来自巴尔的摩老龄化纵向研究口腔生理学部分的99名健康志愿者被分为4个年龄组，年龄从21岁到96岁不等。使用多变量方差分析来确定年龄组和性别之间力量和耐力的差异。通过回归分析确定力量和耐力与年龄的关系。性别分析表明，男性的舌头和手的力量都更大；然而，舌头和手的耐力没有性别差异。舌头和手的力量都随着年龄的增长而减弱。79岁以上的人舌力下降，59岁以上的人手力下降。舌和手的耐力随年龄无明显变化。这项研究的结果表明，舌头的功能与性别和年龄有关，并遵循与手功能相同的趋势。老年人和女性的舌头力量会减弱，而舌头的耐力则与性别和年龄无关。
Background. It is generally accepted that age-related changes occur in voluntary muscle. Studies of hand grip strength and aging demonstrate a decrease in strength with age; however, there are little data regarding tongue function. The purpose of this study was to determine the relationship of increased age to tongue strength and endurance.Methods. A pressure transducer, the Iowa Oral Performance Instrument, was used to measure maximal strength and endurance of both the hand and tongue. Ninety-nine healthy volunteers from the oral physiology component of the Baltimore Longitudinal Study of Aging were divided into four age groups, ranging from 21 to 96 years of age. A multivariate analysis of variance was used to determine differences in strength and endurance between age groups and genders. Regression analysis was done to determine the relationship of strength and endurance with age.Results. Gender analysis indicated that both tongue and hand strength were greater in males; however, tongue and hand endurance demonstrated no gender differences. The strength in both the tongue and hand decreased with age. Individuals over the age of 79 years showed statistically decreased tongue strength, and individuals over the age of 59 years showed statistically decreased hand strength. There was no significant change in the tongue and hand endurance with age.Conclusions. The results of this study suggest that tongue function is gender- and age-dependent and follows the same trends as hand function. Tongue strength is decreased in older individuals and females, while tongue endurance is gender- and age-independent.
