篮球basketball详解.ppt

篮球运动是1891年由美国马萨诸塞州斯普林菲尔德市基督教青年会训练学校体育教师詹姆士·奈史密斯博士发明的。当时，由于在寒冷的冬季，人们缺乏室内进行体育活动的球类竞赛项目，奈史密斯便从工人和儿童用球向“桃子筐”投准的游戏中得到启发，设计将两只桃篮分别钉在健身房内两端看台的栏杆上，桃篮口水平向上，距地面10英尺，以足球为比赛工具向篮内投掷，入篮得1分，按得分多少决定胜负。因为这项游戏最初使用的是桃篮和球，遂取名为篮球。1893年铁质球篮取代了桃篮并挂上了线网。1895年篮筐开始固定在4×6英尺的篮板上并逐渐深入场内，到1913年，由于每次投篮命中后都需要将球从篮筐内捞出太麻烦，于是人们将篮网底部剪开，形成了近似现代的篮板和球篮。 2. Definition of basketball Basketball is a team sport in which two teams of five active players each try to score points against one another by propelling a ball through a 10?feet?(3?m) high hoop (the goal) under organized rules. A regulation basketball court in international games is 28 by 15 meters (approx. 92 by 49 ft) and in the NBA is 94 by 50 feet (29 by 15 m). Most courts are made of wood. A steel basket with net and backboard hang over each end of the court. Basic skills Moving Passing Receiving Dribbling Shooting Rebounding driving Two most common shots The two most common shots that use the above described set up are the set shot and the jump shot. The set shot is taken from a standing position, with neither foot leaving the floor, typically used for free throws. The jump shot is taken while in mid-air, near the top of the jump. This provides much greater power and range, and it also allows the player to elevate over the defender. Failure to release the ball before returning the feet to the ground is a traveling violation. Layup and Slam Dunk Another common shot is called the layup. This shot requires the player to be in motion toward the basket, and to lay the ball up and into the basket The most crowd-pleasing, and typically highest-percentage accuracy shot is the slam dunk, in which the player jumps very high, and throws the ball downward, straight through the hoop. dunk To score by putting the ball directly through the basket with one or both hands. layup?
