This clinical trial is a multicenter, single-blind, prospective, randomized controlled clinical application study. Subjects who met the trial criteria and signed the informed consent form were randomly divided into a control group, an experimental group 1, and an experimental group 2. After enrollment, the control group underwent a comprehensive assessment of their underlying conditions by professional physicians and received routine interventions, including basic nutritional intervention program guidance, progressive resistance exercise intervention program guidance, safety precautions, and symptomatic treatment for different complications, for a total intervention period of 24 weeks. The experimental group 1, in addition to the interventions provided to the control group, received whey protein powder supplementation for 12 weeks. The experimental group 2, on the other hand, received both whey protein powder and eldecalcitol supplementation on top of the interventions given to the control group, also for 12 weeks. The entire intervention period lasted for 24 weeks. Through regular general assessments, blood tests, measurements of muscle mass, muscle strength, and physical function, as well as analyses of negative adverse events, statistical methods were employed to evaluate the safety and efficacy of the comprehensive intervention methods for sarcopenia.

whey protein powder
Dietary supplementThe protein intake is 60 grams per day, taken in three divided doses for 12 consecutive weeks. Attention should be paid to monitoring liver and kidney function, and the dosage of protein powder should be adjusted according to the condition of the patient.
Eldecalcitol
DrugEldecalcitol soft gel capsules are taken at an oral dose of 0.75μg once a day for 12 consecutive weeks.
muscle mass
The DXA equipment is used to detect the muscle mass.
Grip strength
Using a spring dynamometer, stand upright with the elbow joint fully extended, and use the muscle strength of the dominant hand to record the maximum reading (in kg) from three trials.
6-meter walking speed
Record the time required to walk 6 meters from the starting point at a normal speed without decelerating, and use the average result of 3 trials as the recorded walking speed (in m/s).
incidence of adverse reactions
The number of patients with adverse events within a unit time / the total number of patients in the experimental or control group during the same period \* 100%.
