Massage has a direct effect on the muscles. The pumping action helps remove lactic acid and toxins, which builds up in over worked or over exercised muscles, thus reducing weakness and stiffness.
It also improves circulation, which results in quicker delivery of nutrients and oxygen to muscles and faster removal of carbon dioxide. This enables muscles to function at their optimum level.
Manipulation of muscles leads to relaxation and lengthening of that muscle, improving flexibility. Whilst the soothing, stroking, effleurage techniques of massage help to reduce stiffness and immobility around joints and improves posture.
