A lacrosse ball is the solid rubber ball that is used, in conjunction with a lacrosse stick, to play the sport of lacrosse. It is typically white, but is also produced in a wide range of colors. The old NCAA specifications are: ;Weight: 140g - 147g ;Diameter: 62.7 mm - 64.7 mm ;Rebound: From 1,800 height 1,092 - 1292 mm (70% rebound from falling point) ;Rubber content: 65% The new NCAA year 2000 specs states: "Section 17. The ball shall be white, yellow or orange solid rubber between 7 3/4 and 8 inches in circumference, between 5 and 5 1/2 ounces in weight and when dropped from a height of 72 inches upon concrete floor, shall bounce 43 to 51 inches at a temperature of 65 degrees fahrenheit." Beginning with the 2014 season, all three governing bodies for lacrosse in the United States (US Lacrosse, NFHS, NCAA) have mandated that only balls meeting the NOCSAE ball standard may be used for competition. Balls must be emblazoned with the words "Meets NOCSAE Standard" in order to be deemed legal for play by game officials. ==Manufacturers== The three main manufacturers of lacrosse balls are Warrior, STX, and Brine. Warrior is the exclusive supplier of lacrosse balls to Major League Lacrosse with their orange "justin diamond" ball, Brine is the official supplier of lacrosse balls to the NCAA and STX is commonly used in high school and Jr (little league) lacrosse. The National Lacrosse League uses Under Armour balls meeting NCAA standards. In Canadian box lacrosse all balls must be CLA approved. The main brand in which Canadian box lacrosse balls are used is Gait. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lacrosse ball」の詳細全文を読む スポンサード リンク
