Fascia refers to a kind of thin film tissue fixed around muscles in human body, which is composed of collagen fibers and plays a role in supporting, protecting and regulating muscle movement. Fascia is widely distributed in human body, which not only surrounds muscles, but also covers bones, organs and nerves, so it is very important for human health.

Fascia has attracted much attention in recent years. Many physiotherapists, athletes and fitness enthusiasts believe that the function of fascia is closely related to sports performance. Through fascia relaxation, fascia roller, stretching and other means, the flexibility of muscles and joints is increased, and the pain caused by fascia and muscle tension is alleviated.

However, some viewpoints and theories about fascia need more research and confirmation. Some health experts believe that keeping a static posture for a long time and lacking moderate exercise may lead to the stiffening and rigidity of fascia, increasing the risk of muscle strain and other sports injuries. Therefore, it is very important for people who want to exercise or sit for a long time to maintain proper physical activity and stretching.
