The function of elbow and knee protection

Elbow and knee protectors are protective devices designed to prevent elbow and knee injuries from falling, and are worn with soft cushions or hard shells. To reduce the weight of the equipment, designers have designed elbow and knee pads to be lighter, more aesthetically pleasing, more convenient, and more practical.
Friends who enjoy playing tennis, badminton, and table tennis may experience elbow pain after a game, especially when playing backhand. Even if they wear elbow protectors, they may still feel pain. Experts tell us that this is commonly known as the "tennis elbow". Moreover, this tennis elbow is mainly used at the moment of hitting the ball, where the wrist joint is not braked or locked, and the extensor muscle of the forearm is excessively pulled, causing damage to the attachment point. After protecting the elbow joint, the wrist joint is not protected, so there is still an excessive over bending movement during hitting, which can further aggravate the damage to the elbow joint. So when playing tennis, if you feel elbow pain, it's best to wear wrist protectors while wearing elbow protectors. And when choosing wrist protectors, everyone must choose ones that have no elasticity, as if the elasticity is too good, it will not have a protective effect. And when wearing it, it should not be too tight or too loose, as it will affect blood circulation, and if it is too loose, it will not have a protective effect.
