what is the purpose of arm sleeves in basketball
Basketball sleeve Allen Iverson began using a basketball sleeve during the 2000-01 season due to bursitis in his right elbow.[3] Afterward, fans wore the sleeve as a fashion statement,[4] and by 2008, the sleeves were the most popular non-apparel items sold by the league, according to an NBA Store spokesperson.[5] Other players, including Ray Allen, Vince Carter, Russell Westbrook, Chris Paul, Carmelo Anthony, Dwight Howard, Paul Pierce, John Wall, Kyrie Irving, Dwyane Wade, Paul George, Kobe Bryant,[6] and LeBron James[2] have worn the sleeves as well.
Basketball court The key, free throw lane or shaded lane refers to the usually painted area beneath the basket; for the NBA it is 16 feet (4.9 m) wide, for the NCAA it is 12 feet (3.7 m) wide; for both instances it extends 15 feet (4.6 m) from the backboard. At the top of the rectangle is the free throw line, behind which players shoot uncontested shots when they're fouled. A circle is drawn around the free-throw line with a 6 feet (1.8 m) radius; this is used for jump ball instances, as is done at the center circle. Two 6-inch hash lines, 3 ft from the free throw lane line and 5 ft 8 in from the free throw line, show the lower defensive box linked to the restricted area.
