Massage and the circulatory system
Massage in any form will affect the circulatory system both in the quantity of blood moved through the circulatory system and the quality of the blood. With massage applied correctly it will cause hyperemia or an increase of blood flow to a localized area of the body, better circulation and increased nutrients to a localized area will have a positive affect. Elimination to the area will also be increased allowing for better cellular metabolism. The heart will no have to work as hard when there is an improved circulation to the surface of the skin. Blood pressure and heart rate are reduced while the massage is taking place. The systolic stroke volume is increased and the capillary beds dilate allowing the blood to flow more freely and be more permeable.
Massage can also improve the production of red blood cells and white blood cells boosting the immune system and oxygenation of the entire body. In 1992, a study was conducted with HIV positive patients that resulted in the conclusion that massage will boost the immune system. The evidence that additional T4 killer cells where found in the bloodstream lead them to believe that massage in any form would allow the production of more white blood cells and indicated that massage might strengthen the immune system.
Massage strokes affect the blood and lymph flow as listed:
- Light strokes produce an almost instant dilation of the capillaries and deep strokes dilate a more long lasting and flushing of the localized area being massaged.
- Light percussion causes a contraction of the blood vessels, which after a length of time relaxation kicks in.
- Friction increases the flow of blood through superficial veins, and produces a flow of interstitial fluids back through the lymph system.
- Petrissage or kneading stimulates blood flow through muscle and even deep arteries and veins.
- Light massage of MLD (Manual Lymph drainage) applied properly enhances lymph flow and reduces lymphedema.
- Compression causes hyperemia or an increase in the amount of blood stored in the muscle tissue.
