| Summary: | 碩士 === 中臺科技大學 === 護理系碩士班 === 107 === Background: In middle-aged and elderly people, skeletal muscle mass will be lost with age, leading to decreased muscle function. The aging-related skeletal muscle loss is called sarcopenia. The incidence of annual falls from the middle-aged and elderly people in the community is about 30-40%. The fall is mainly due to the decline of muscle endurance in the lower limbs, which leads to the loss of the independence of daily life function, which affects the quality of life and will also affect mental health. In severe cases, it may cause disability or death. It can be seen that the prevention of lower limb muscle weakness in middle-aged and elderly people should be taken seriously.
Purpose: This study explored the effects of lower extremity exercise intervention on middle-aged and elderly people to improve their self-efficacy, sleep quality and physical and mental health.
Methods: This research method is for the middle-aged and elderly people who are over 55 years old of community care center, and have agreed to participate in the project, by purposive sampling, They are divided into the experimental group and the control group, 50 cases of control group and 50 cases of the experimental group receive lower extremity exercise intervention for 12 weeks, 3 times a week. Each intervention time is 50 minutes, and to conduct pre- and post-intervention tests, compare the presence or absence lower extremity exercise intervention of the difference in exercise self-efficacy and physical and mental health of the middle-aged and elderly people with lower limb movement.
Results: Lower limb muscle strength and stretching exercises in the community are involved in improving functional fitness (30-s chair-stand test, 8 foot up-and-go test, 2-minute leg-lift test, chair sit-and-reach test), exercise self-efficacy, the overall mental health status, and the basic physiological indexes (waist circumference, body fat ratio, body mass index BMI, body weight) and sleep quality, the experimental group improved the value better than the control group (p < .05).
Conclusion: It is recommended to popularize the concept and application of lower limb movement intervention to promote physical and mental health in community, clinical hospitalization and long-term care institutions, effectively prevent aging and disability of lower extremity muscle strength, so as to reduce the cost of medical care.
