Final answer:
Reduced or low tongue endurance is a decrease in the tongue's muscle ability to perform actions over time, often due to medical conditions. Assessing tongue endurance is critical for activities like speech and swallowing, and targeted exercises can enhance endurance.
Step-by-step explanation:
Reduced tongue endurance, in seconds, refers to the decreased ability of the tongue's muscles to perform sustained or repetitive actions over a period of time. It is often measured to assess the functional status and strength of the tongue, which is important for several activities including speech and swallowing. Individuals with certain medical conditions may experience low tongue endurance, affecting their quality of life. Targeted exercises under the supervision of a speech-language pathologist or medical professional can be beneficial in improving the endurance of the tongue muscles.
