Arm guards first appeared in the NBA. The first NBA player to wear arm guards was Allen Iverson. The arm guard has two colors at the beginning, white and black. Later, in order to meet people's needs, other colors came into being. For example, Allen Iverson's right elbow was comminuted fracture in an accident. After recovering, Iverson's company made arm protectors to protect its star players.

Professional basketball players have excessive use of muscle fibers in the elbows due to long and high-intensity competitions, especially guards. This is also why many basketball players have tendonitis, bursitis and other elbow diseases.During exercise, the movement of the elbow causes an increase in pain, which greatly affects the player's play and the feel of the shot. The compression provided by the arm guard reduces the pain and discomfort of the elbow and reduces the chance of re-injury.
The arm guard keeps the arm temperature and muscle tightness. The temperature is to ensure that the arm's energy is not easily lost. The tightness is to keep the muscles in a state of vigorous exercise and it is not easy to strain the arm muscles or cramps. Quickly wick away sweat and lower body temperature. Wearing arm braces can expel sweat quickly, control body temperature on human epidermis, and ensure the best state of movement.
When playing basketball, there will be breakthroughs or dunks. Wearing armguards can prevent physical injury caused by collisions that may occur in the course of sports. The arm guard can also prevent re-injury of the injured part.
Steady shooting position.Moderate directional compression can make shooting less biased.It can exert pressure on the muscles to promote blood circulation. The compression provided by the arm guard increases blood circulation and delivers more oxygen to the muscles. At the same time, lowering the level of lactic acid and blood in the blood, lactic acid push and blood stasis may cause swelling, muscle aches and decreased exercise performance.
