Sarcopenia, an age-dependent loss of muscle mass and function, is a common disorder in older adults and is associated with adverse health outcomes. Sarcopenia patients suffer from loss of muscle strength and mobility impairments, which reduce their quality of life, with higher risk for falls, fractures, metabolic disease, and mortality [In this study, we found that compared with patients in the control group, patients in the research group receiving nutritional intervention combined with muscle exercise had higher BMI, grip strength, calf circumference, faster walking speed, and body muscle rate after the intervention, which suggests that nutritional intervention combined with muscle exercise can effectively improve symptoms in patients with sarcopenia. Undernutrition is an important cause of sarcopenia in middle-aged and elderly people, and it is also the main direction for the prevention and treatment of sarcopenia [Furthermore, muscle exercise is also very important for improving symptoms in patients with sarcopenia. On the one hand, regular aerobic training can improve the activity of muscle mitochondrial enzymes, increase capillary density, promote nerve repair and motor unit mobility, thereby increasing skeletal muscle strength and exercise capacity [In this study, we also found that the postoperative recovery of the patients in the research group was better than that of the patients in the control group, including higher functional independence scores, shorter fracture healing times and hospital stay time, and lower postoperative VAS pain scores, which indicates that our intervention not only improves sarcopenia symptoms but also accelerates recovery in patients with femoral fractures. Adequate nutrition and protein supplementation can not only slow down muscle atrophy but also help increase muscle strength and help patients with femoral fractures get out of bed early to exercise [All in all, our results in this study indicated that nutritional intervention combined with muscle exercise could help improve sarcopenia symptoms and promote fracture recovery in patients with sarcopenic femoral fractures. However, as a single center study, there are problems such as a single research population and a small sample size. In the future, we need to expand the sample size to verify the accuracy of the results.
