The main purpose of this study is to screen middle-aged and elderly (≧ 45 years old) individuals at high risk of sarcopenia and sarcopenia, and to investigate whether sarcopenia can improve dental bite force and tongue pressure in middle-aged and elderly sarcopenia subjects when given edible chewing training colloidal intervention.This trial method will recruit 120 subjects for oral strength training twice a day for 8 weeks, and compare the difference in chewing level between the subjects using the oral strength training intervention and the oral strength training intervention before and after the test. The differences between dental occlusal force and tongue pressure after training were also explored. The experiment mainly evaluated the scales related to dental occlusal force, tongue pressure, and quality of life, because the quality of oral muscles is highly correlated with the diet and lifestyle of the elderly, and also affects the physical health and mobility of the elderly. Although the loss of muscle mass due to aging may be unavoidable, appropriate oral strength training intervention may delay or modify the adverse effects of sarcopenia and improve quality of life in sarcopenia subjects.
