Progressive Muscle Relaxation For Stress Reduction. Kinetic or movement related stress relief practices need not involve a lot of exertion to be effective. Progressive muscle relaxation, or PMR, is a stress relief technique that relies upon subtle rather than gross (large) muscular movements to promote relaxation and tension relief. Progressive muscle relaxation is based on the observation that it is easier for muscles to relax from a position of high tension than it is from a position of lower tension. The kind of muscular tension that causes headaches and bodily pains tends to be a sort of moderate residual tension that people walk around with (and may not notice) for days.
A cramp is the tightening of a muscle into the contracted state. Muscles have two states: relaxed and contracted. A muscle is relaxed when all of the fibers within the muscle are elongated. When the muscle does its job, calcium goes into the muscle cells and sodium rushes out. Doing so causes the fibers to shorten and the muscle to pull--doing itâs work.
