Effleurage, characterized by its long, sweeping strokes, is particularly effective in warming the tissues and promoting blood flow. It can also help to soothe the nervous system, which indirectly supports circulation.

Friction involves more localized, deeper pressures and movements that stimulate blood flow to specific areas, which can be beneficial for relieving muscle tension and enhancing circulation in those areas.

Tapotement consists of rhythmic tapping or percussion movements, which stimulate and energize the muscles and tissues, encouraging increased blood circulation.
