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.

Extremity Skeletal Muscle Mass Index (ASMI)
ASM was measured using BIA, ASMI=ASM/height (m)\^2.
Time frame: Baseline, month 3, month 6
Handgrip strength
Maximum force grip was held for 3 seconds, the right and left hands were measured alternately, 3 measurements were taken in each hand, and the maximum value was taken.
Time frame: Baseline, month 3, month 6
6m walking speed
Let the tester start from the starting point, walk 6 meters at normal walking speed, stop when reaching the end point, record the time used, and calculate the 6m walking speed according to the time used and the distance of 6 meters.
Time frame: Baseline, month 3, month 6
Chair sitting and standing test
The subject sat in the center of the chair, crossed his/her arms in front of his/her chest, and after hearing the command "start", he/she completed 5 consecutive times of standing up and sitting down, and recorded the total time in seconds.
Time frame: Baseline, month 3, month 6
Simple Physical Performance Battery (SPPB)
The SPPB consists of 3 test items, each item is scored out of 4 points, and the total score is 12.
Time frame: Baseline, month 3, month 6
General survey
Using a questionnaire designed by the research team and validated by the previous study, the survey covered the age, gender, ethnicity, marital status, occupation, education level, place of residence, household income, living status (living alone and with family), dietary habits and application of nutritional supplements, lifestyle (smoking, drinking, and physical activity), family history, and chronic diseases (hypertension, diabetes, etc.) of the study participants, Hyperlipidemia, etc.)
Time frame: Baseline, month 6
Height
Measure the height of the subjects
Time frame: Baseline, month 3, month 6
Weight
Measure the weight of the subjects
Time frame: Baseline, month 3, month 6
Body Mass Index(BMI)
Calculate BMI using height and weight , BMI=weight/(height)\^2
Time frame: 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).
Time frame: 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.
Time frame: 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.
Time frame: 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.
Time frame: Baseline, month 3, month 6
Analysis of dietary intake
The 3-day, 24-hour dietary recall method was used to investigate the subjects' dietary intake. The survey process was supplemented with tools such as the "Retrospective Dietary Survey Auxiliary Chart" to help the subjects accurately recall their dietary intake. Based on the Standardized Version of the Chinese Food Composition Table (6th Edition), the energy and various types of protein, fat and carbohydrate intake of the population were calculated, and for the missing data in the Chinese Food Composition Table, the United States Department of Agriculture Food Composition Table was used to supplement the data, so as to build up a comprehensive database of dietary intake. The analysis of dietary intake included the intake of total fat, total protein, total carbohydrates and energy and its percentage in the total energy intake.
