目的：研究已知的肌肉训练原理在舌强化训练中的应用，并回答以下研究问题：(A)训练9周后，舌力是否增加？(B)使用向一个方向移动舌头的练习进行的训练是否会导致向其他方向移动舌头的力量发生变化？(C)是否观察到参与者按顺序(单独)或同时(多个练习组合)完成练习的不同训练效果？(D)在停止锻炼后力量增长是否保持？方法：受试者为39名健康成年人，被分配到连续或同时进行语言力量训练。进行为期9周的舌力训练(抬高、突出和/或偏侧)，每周评估一次舌力和面颊力量(对照变量)。结果：随着训练的进行，所有的舌力指标都有所增加，但面颊力量保持不变。训练效果与训练条件无关(顺序训练与同时训练)，也没有观察到运动方向的特异性效应。停止训练2-4周后，舌力明显下降。结论：本研究结果重复了早期研究的结果，表明不同的训练方案可以增加舌力，并证实了停止训练时可以观察到取消训练的效果。研究结果进一步表明，舌部肌肉系统表现出的训练专一性可能不如已报道的骨骼肌训练专一性。
Purpose: To examine the application of known muscle training principles to tongue strengthening exercises and to answer the following research questions: (a) Did lingual strength increase following 9 weeks of training? (b) Did training conducted using an exercise moving the tongue in one direction result in strength changes for tongue movements in other directions? (c) Were differential training effects observed for participants completing exercises sequentially (in isolation) versus concurrently (several exercises in combination)? (d) Were strength gains maintained after exercise was discontinued?Methods: Participants were 39 healthy adults assigned to sequential or concurrent lingual strength training. Lingual exercise (elevation, protrusion, and/or lateralization) was conducted for 9 weeks, with lingual strength and cheek strength (control variable) assessed weekly.Results: All lingual strength measures increased with training, but cheek strength remained unchanged. Training effects were not related to training condition (sequential vs. concurrent), nor were specificity effects observed for direction of exercise. Significant decreases in lingual strength were noted 2-4 weeks after exercise was discontinued.Conclusions: The findings replicate those of earlier studies demonstrating that lingual strength may be increased with a variety of exercise protocols and confirm that detraining effects may be observed when training is discontinued. The findings further suggest that the lingual musculature may demonstrate less dramatic training specificity than what has been reported for skeletal muscles.
