The aim of the present study was to investigate whether anterior tongue muscle strengthening exercises can affect the strength of posterior tongue muscles.
Eleven healthy subjects (20.6 ± 1.2 years) were included. The subjects exercised by pushing the anterior tongue to the palate 30 times, three times a day, 3 days a week for 8 weeks. The exercise intensity was set at 60% of maximum tongue pressure (MTP) in the first week and 80% of MTP for the remainder of training. After the completion of training, MTP measurements were continued every month for another 3 months to evaluate whether training effects were sustained.
MTP was significantly increased after 8 weeks of training compared with before training. No significant differences were seen between MTP immediately after completion of training and MTP 1-3 months after completion of training. However, MTP was significantly higher 1-3 months after completion of training than before training.
The present study showed significant increases in both anterior and posterior MTPs by anterior tongue muscle strengthening exercises. In the future, a database on tongue muscle strengthening exercises in elderly persons, patients with dysphagia, etc. will need to be generated, with the aim of preventing frailty.
本研究旨在探讨前舌肌强化训练是否会影响后舌肌的力量。
纳入 11 名健康受试者（20.6±1.2 岁）。受试者每天 3 次，每次 30 次，将前舌推向硬腭，持续 8 周。第 1 周的运动强度设定为最大舌压（MTP）的 60%，其余训练为 80%的 MTP。训练完成后，每月继续进行 MTP 测量，以评估训练效果是否持续。
与训练前相比，8 周训练后 MTP 显著增加。训练结束后即刻与训练结束后 1-3 个月之间 MTP 无显著差异。然而，训练结束后 1-3 个月的 MTP 明显高于训练前。
本研究表明，前舌肌强化训练可显著增加前、后 MTP。未来，需要针对老年人、吞咽困难患者等人群生成舌肌强化训练数据库，以预防虚弱。
