Sarcopenia is a syndrome characterized by progressive generalized loss of bone spur muscle mass and function. Poor health maintenance manifested as a decrease in body weight bone spur muscle mass reduction abnormal muscle strength and decline in physical function etc. will enter and lead to muscle loss with a small amount of symptoms or even cachexia resulting in poor curative effect decreased quality of life and shortened life span. Studies in recent years have shown that giving ω-3 PUFAs and fatty acid intervention the effects of ω-3 PUFAs on anti-inflammation improving nutrient sensitivity improving metabolic flexibility and energy utilization are likely to change the bone status of skillful patients mechanisms. In recent years there has been more interest in intervention research related to less muscle loss in brittle people but there are relatively few clinical studies on whether ω-3 PUFAs intervention materials can improve the state of bone spurs in brittle people and there are fewer evaluation indicators involved. Various studies exist where results are inconsistent. In order to guide the standardized application of ω- 3 PUFAs in clinical practice this article reviews the related research on ω-3 PUFAs in modifying the skeletal state of myalgia patients hoping to establish a certain theoretical basis for the nutritional treatment of sarcopenia in patients with arthralgia.
