Sarcopenia is an age-related progressive skeletal muscle disease, the prevalence of which is increasing year by year with the aging of China's population, seriously affecting the health and quality of life of the elderly. Relevant studies have shown that protein intake in combination with resistance exercise can significantly improve muscle mass and function, and the effect is superior to that of a single intervention. In addition, ingredients such as vitamin D, N-acetylglucosamine, sodium hyaluronate, and taurine can further promote muscle health by regulating metabolism and inflammation levels. However, there are relatively few intervention studies combining the above nutrients with resistance exercise in patients with sarcopenia. Therefore, this study intends to use protein powder containing milk protein, vitamin D, N-acetylglucosamine, sodium hyaluronate, taurine and other ingredients, combined with low-intensity resistance exercise, to intervene in the middle-aged and elderly patients with sarcopenia, and to explore and observe the effects on muscle mass, bone density, intestinal health and other indexes of patients with sarcopenia, with the aim of providing a more accurate nutritional and exercise intervention program for the prevention and treatment of sarcopenia.

| Resistance exercise intervention | Behavioral | Low-intensity resistance training was conducted 3 times a week. |
|
| Placebo control | Dietary Supplement | placebo was given and an individualized balanced dietary plan based on the Dietary Guidelines for Chinese Residents was provided. |
|
| Baseline, month 6 |
| Height | Measure the height of the subjects | Baseline, month 3, month 6 |
| Weight | Measure the weight of the subjects | Baseline, month 3, month 6 |
| Body Mass Index(BMI) | Calculate BMI using height and weight , BMI=weight/(height)^2 | Baseline, month 6 |
| Waist circumference, hip circumference, and waist to hip ratio | Measure the waist and hip circumference of the subjects and calculate the waist to hip ratio (waist circumference/hip circumference). | Baseline, month 3, month 6 |
| Body composition | Using a human body composition analyzer to detect indicators such as total score, visceral fat area, body segment fat and basal metabolic rate, body cell mass, and limb skeletal muscle mass index. | Baseline, month 6 |
| Assessment of ability to perform activities of daily living | The ADL was assessed using the Activity of Daily Living Scale (ADL), which consists of 10 items, including eating, bathing, grooming, dressing, bowel control, urination control, toileting, bed and chair transfers, walking, and walking up and down stairs. The total score is 100, with a score of more than 60 indicating mild functional impairment but basic self-care in daily life; a score of 60-41 indicating moderate functional impairment and need for some assistance in daily life; a score of 40-21 indicating severe functional impairment and obvious need for dependence on others in daily life; and a score of less than 20 indicating complete disability and total dependence on others in daily life. | Baseline, month 3, month 6 |
| Sleep assessment | The PSQI (Pittsburgh Sleep Quality Index) questionnaire was used to assess the quality of the subjects' sleep during the last 1 month. It consists of 19 self-assessment and 5 other-assessment entries, of which the 19th self-assessment and 5 other-assessment entries are not involved in scoring. The cumulative score of each component is the total PSQI score, which ranges from 0 to 21, with higher scores indicating poorer sleep quality. | Baseline, month 3, month 6 |
