STRETCHING ANATOMY

STRETCHING ANATOMY Types of Stretching In general, any movement that is part of the point at which there is can increase in the movement of a joint can be called a stretching exercise.Stretching can be done either actively or passively. Active stretching occurs when the person doing the stretch is the one holding the body part in the stretched position. Passive stretching occurs when someone else moves the stretch position and then holds the person in the position for a set time. The four major types of stretches are static, proprio- ceptive neuromuscular facilitation (PNF), ballistic, and dynamic.The static stretch is used most often.In static stretching, one stretches a particular muscle or group of muscles by slowly moving the body part into position and then holding the stretch for a set time. Since the static stretch begins with a relaxed muscle and then applies the stretch slowly, static stretching does not activate the stretch reflex (the knee jerk is seen when the tendon is tapped with a mallet). Activation of the stretch reflex causes the stretched muscle to contract instead of elongate. This contract is directly opposite of the intent PNF stretching is a stretching technique in which a fully contracted muscle is stretched by moving a limb through the joint's range of motion through the complete range of motion, the muscle is relaxed and rested before resuming the procedure.The contraction and stretching serves to relax the muscles used to maintain muscle tone. This relaxation allows for increased flexibility by "Quieting" the internal forces that help and the ones that oppose the movement of the joint in the desired direction. Ballistic stretching uses muscle contractions to force muscle elongation through bobbing movements where there is no pause at any point in the movement. Although the bobbing movement quickly elongates the muscle with each repetition, the bobbing also activates the stretch reflex (or knee jerk) response. Since the stretch of reflex stimulates the muscle groups to contract after the stretch is finished, Ballistic stretching is usually discouraged. Dynamic stretching refers to the stretching that occurs while performing sports-specific movements. Dynamic stretching is similar to ballistic stretching in that both use fast body movements to cause muscle stretch, but dynamic stretching does not employ bounce or bobbing. Additional, dynamic stretching uses only the muscle specific actions to a sport.Practically speaking, dynamic stretching is similar to perform a sport-specific warm-up (that is, performing the movements required for the activity but at a lower intensity).
