Stretching Muscle

Stretching the muscles is very good for them. Stretching every day improves flexibility, improves athletic performance and reduces the risk of other forms of physical activity blessing. Stretching a muscle actually the strongest, according to the "Journal of Applied Physiology." Regular stretching exercises increase your range of motion and realign the tissue inside the muscle fibers. The stretching action takes place deep in the muscle tissue and the points where the muscles meet with the bones.
function

Bones protect your body and support your body. Skeletal muscles move the bones along the pivot points, or at the joints, through pairs or groups of muscles that act in concert to produce movement. The ligaments connect the muscles to the bones. Certain muscles contract to extract the other, while others are relaxed to allow movement. Stretching improves the contraction and relaxation phases and the reorganization of muscle fibers of the smile muscle are in concert in concert with others.
Contraction and stretching

Muscles gain the strength to move the bone through a narrowing effect and cumulative elongation. Limiting a cell can not move a bone, but hundreds of cells can swarm some tissue and large tissue areas twist to exert enough force to move a bone along a joint. Stretch works in the same way in the opposite direction. The length of the entire muscle depends on the number of stretched fibers - an increase in the amount of stretched fibers increases the amount a muscle can stretch.

physiology

The muscles are able to contract, lengthen and stretch because of their unique physiology. This property is known as elasticity. The muscles are many, the strands of tissue known as leaflets, as seen in the set of cuts of meat. Each part consists of bundles of muscle fibers, which, in turn, contain tens of thousands of myofibrils. Myofibrils are filiform structures capable of contracting, relaxing and stretching. Within each of the myofibrils, millions of strips are placed end to end, called sarcomeres, which are made of thick filaments and thin litter. When contracted, thick and thin filaments overlap, causing muscle contraction. Muscle contraction causes an increase in the overlap of myofilaments.

Relaxing a muscle causes a decrease in myofilament overlap, which then allows the muscle fibers to elongate. At this stage, the sarcônes are in their maximum length. Any movement of additional stretching exercises a strain on the ligaments that attach the muscle to the bone. As the stretching movement increases tension in the connective tissue, the collagen fibers in the connective tissue are aligned along the same line of force as the tension.

Stretching a muscle causes a contraction in the opposite muscle and vice versa. For example, the extension of the leg to stretch the hamstring contracting simultaneously the quadriceps. (The quad is responsible for the action of the leg extension). Thus, even by stretching, too much - remote muscle group (s) is tightened. Lifting involves two types of contractions: concentric and eccentric. Hanging the upward movement of a biceps curl, biceps feels a concentric contraction, triceps undergoes an eccentric contraction (muscle stretching). The opposite occurs when the arm extends during the eccentric phase of the exercise.
benefit

The stretching motion of a muscle is re-aligned to disorganized muscle and connective tissue fibers. The injuries and muscles that cause the fibers of the connective tissue to be seasonally adjusted. Physical therapy includes stretching exercises specifically because of this readjustment action of injured connective tissue fiber.
