Thus, a good discus thrower needs to maintain balance within the circle. This is due to the throw being a linear movement combined with a one and a half rotation and an implement at the end of one arm. Executing a sound discus throw with solid technique requires perfect balance. They then begin the wind-up, which sets the tone for the entire throw the rhythm of the wind-up and throw is very important.įocusing on rhythm can bring about the consistency to get in the right positions that many throwers lack. They crouch in order to adopt a more efficient posture to start from whilst also isometrically preloading their muscles this will allow them to start faster and achieve a more powerful throw. Initially, the thrower takes up their position in the throwing circle, distributing their body weight evenly over both feet, which are roughly shoulder width apart. Rutger Smith in phases of the discus throw The technique of discus throwing is quite difficult to master and needs much experience to perfect thus most top throwers are 30 years old or more. Also, a faster-spinning discus imparts greater gyroscopic stability. Generally, throws into a moderate headwind achieve the maximum distance. As well as achieving maximum momentum in the discus on throwing, the discus' distance is also determined by the trajectory the thrower imparts, as well as the aerodynamic behavior of the discus. In flight the disc spins clockwise when viewed from above for a right-handed thrower, and anticlockwise for a left-handed thrower. The discus is spun off the index finger or the middle finger of the throwing hand. The basic motion is a fore-handed sidearm movement. The rules of competition for discus are virtually identical to those of shot put, except that the circle is larger, a stop board is not used and there are no form rules concerning how the discus is to be thrown. The discus must land within a 34.92º circular sector that is centered on the throwing circle.
They then spin anticlockwise (for right-handers) 1 + 1⁄ 2 times while staying within the circle to build momentum before releasing the discus. The thrower typically takes an initial stance facing away from the direction of the throw. To make a throw, the competitor starts in a circle of 2.5 m ( 8 ft 2 + 1⁄ 4 in) diameter, which is recessed in a concrete pad by 20 millimetres (0.79 in). In some competitions, a solid rubber discus is used (see in the United States). However, a higher rim weight, if thrown correctly, can lead to a longer throw. A discus with more weight in the rim produces greater angular momentum for any given spin rate, and thus more stability, although it is more difficult to throw. The rim must be smooth, with no roughness or finger holds.
The typical discus has sides made of plastic, wood, fiberglass, carbon fiber or metal with a metal rim and a metal core to attain the weight. His suggestion was adopted by the National High School Athletic Association in 1938. In the United States, Henry Canine advocated for a lighter-weight discus in high school competition.
The weight of the discus is either governed by the World Athletics for international or USA Track & Field for the United States. Men and women throw different sized discs, with varying sizes and weights depending on age. The event consists of throwing a disc, with the weight or size depending on the competitor. Following competition at national and regional levels, it was added to the Olympic program for the 1928 games. Women's competition began in the first decades of the 20th century. After only one year of developing the technique, he earned a silver medal in the 1900 Olympics. Janda-Suk invented this technique when studying the position of the famous statue of Discobolus. The first modern athlete to throw the discus while rotating the whole body was František Janda-Suk from Bohemia (the present Czech Republic).
