Therefore, when a muscle contracts, it is not only a row of proteins getting closer together and shortening the muscle. So, muscles are layers and layers of fascia around contracting proteins. This outer layer can be likened to the peel of the citrus fruit. And finally, the muscles itself is a bundle of fascicles that are surrounded with yet another later of fascia, called the epimysium. A muscle fascicle can be compared to the wedge in citrus fruits, which is a group of pieces of pulp. A group of these muscle cells bundled together and wrapped with another layer of fascia and we have a muscle fascicle. In these muscle cells, the skin is a layer of fascia. These muscle cells are like the pieces of pulp in citrus fruit, each of which has its own layer of skin. Now, this is only one single muscle fiber.Ī group of muscle fibers joined together makes a muscle cell. These two proteins pulling toward each other form the basis for any muscular contraction.īut what holds these proteins in place and guides them to contract in a particular direction? Connective tissue, or in this case, to be more specific, fascia. As soon as the nervous system sends the command to release calcium, these proteins get attracted to each other and contract toward each other. A muscle fiber consists of two types of proteins (actin and myosin), arranged in a long row. That movement is produced by muscle fibers. The specific function of muscles is movement. A lack of stretching, especially when combined with activity can lead to a shortening of the soft tissue due to fatigue. The range of motion is influenced by the mobility and elasticity of the soft tissues that surround the joint. Every person's musculoskeletal structure is different and therefore, flexibility differs in each individual. These soft tissues support the joints to function smoothly. The joint is surrounded by soft tissues of muscles, ligaments, tendons, joint capsules, and skin. What is flexibility?Īn unrestricted and pain-free range of motion in joints is called flexibility. In this blog, you'll learn why yoga is actually one of the most effective disciplines to develop both strength and flexibility. Most people think flexibility is a requirement to practice yoga, but this is a misconception. There are two qualities noticeable when you observe the practice of an experienced yoga practitioner: A seemingly perfect harmony of strength and flexibility.
