According to my investigation, the first athlete to wear this colorful wristband on his wrist was Armstrong, a Tour de France cyclist. He wrote some encouraging words on this rubber wristband painted with his favorite color to cheer for his competitors. In a charity event, Armstrong made many wristbands printed with various inspirational words for poor children, so such wristbands were also called inspirational circles at that time. When it was introduced into NBA, the color of wristbands worn by players mostly matched the color of live jerseys, which did not protect wristbands as people said. Just like the red rope worn by Yao Ming, it plays the role of decoration and blessing, or, just like Armstrong, it is used to motivate himself to play the game.
Ask those who say this rubber ring is a protective device. How does this loose belt play a protective role? Are your wrist, elbow and knee pads so loose? If it is such a loose protective gear, it makes no difference whether it is worn or not!
