Fitness for all, a variety of muscle relaxation equipment is also very popular, including massage roller, massage ball, fascia gun is the most common. Physiotherapists remind that these massage devices do have the effect of relaxing the muscles and fascia, but it is important to remember not to hit the bony protrusions and vascular nerve convergence, not to be excessively painful, or to stretch in order to achieve the best effect without causing injury.
These popular massage tools can indeed achieve a certain muscle relaxation effect, including massage rollers for large areas; massage balls can emphasize a small area; fascia gun is similar to a massage ball, through mechanical vibration more effort.
What is more worrying is to see some products claiming that massage rollers or massage balls are better with protrusions, or boasting that fascial guns can promote circulation and sports performance, these are exaggerated and untrue claims.
After exercise, the muscles are more swollen or tight, mechanical pressure, rolling, vibration, in addition to stimulating the mechanical receptors in the muscle, so that the muscle to achieve a certain degree of relaxation, but also in the muscle and fascia squeeze out some space, unstick, promote the flow of body fluids, to help the muscle contraction slide more smoothly.
It is important to note that these massage tools should be applied to the fullest position of the muscles and avoid the bony protrusions and important vascular and nerve areas to avoid bleeding or nerve damage, such as the crotch, armpits, front side of the neck, eye sockets, knee sockets, are not suitable.
In addition, the massage force should be appropriate, the pain should be within the tolerable range, the feeling should be more and more soothing, not more and more pain. If the force is too large to cause excessive pain, but will make the muscle defensive contraction, but more tight after the press. If the body parts have severe pain, twitching, numbness, or the external appearance of obvious swelling or depression and other deformation, may have been injured musculoskeletal, but also can not massage, should seek professional assessment and assistance as soon as possible.
Massage is a passive pressure, stretching is the active contraction of the muscle, the two purposes are different and can not replace each other. It is recommended that those whose muscles are easily tightened and less flexible should have a slight massage after exercise, and then stretching to promote the relaxation of muscle contraction and sliding.
