Discus: official game rules briefly
Discus throwing belongs to the category of athletics disciplines. The meaning of this sport is to throw at a range of a special projectile – the disk. This requires athletes to quickly coordinate their movements and excellent physical fitness.
Rules and requirements
Participants in official competitions must perform a throw from a circle with a diameter of 2.5 m. The throw distance is calculated from the outer circumference of the zone to the first point of the disc’s fall. The standard projectile weight for men is 2 kg, for women – 1 kg, for juniors – 1.5 kg. The diameter of the disc is 20 cm for men and 18 cm for women.
Each participant in the competition receives 6 attempts, but if more than 8 athletes entered the tournament, a preliminary stage is carried out. In this selection, all participants use 3 attempts. Next, 8 strongest players are identified, who determine the winner of the tournament for the remaining 3 attempts.
Today, discus is thrown only from a sector enclosed by a grid with a height of 3.35 to 4 m. To prevent the projectile from crashing into the net, the recommended horizontal departure angle should be no more than 35 degrees. The width of the gate for releasing the disc is 6 m. When thrown, the projectile can touch the fence of the sector, but the athlete is forbidden to go beyond its borders until the disc is completely landing.
A modern shell is made of wood or a similar synthetic material bordered by a metal rim. Two metal plates are fixed in the center of the disk in parallel. The athlete chooses which side to take the disc from.
Disc Throwing Technique
Currently, experts distinguish the following elements and phases of discus throwing:
- Disk holding. The phalanges of the fingers should lie on the edge of the disc. The throwing arm is lowered and sways slightly. The center of gravity lies between the support points of the index and middle fingers.
- Starting position. The athlete stands at the rear edge of the circle with his back in the direction of throwing. The right leg gets the frontal position, and the left is turned in the direction of rotation.
- The swing phase. The drive must be taken back from left to right. In this case, the left arm bends in front of the chest. During the swing, the legs bend slightly and the knees unfold.
- Turn. At this phase, the forward movement of the throwing arm and acceleration of the projectile begin. After a swing, the upper part of the body is left behind, and the right foot is repelled from the ground for landing on the left in the center of the circle. The jump should be flat, without deviating the shoulder girdle.
- Throw position. In this starting position, both legs should maintain contact with the ground. The athlete maintains balance and prepares for the final effort.
- Final effort. The setting of the right leg is a rotationally-rectifying movement. Then there is a rapid turn of the right side of the case. Its left side here plays the role of a lever. At the final stage of the element, the legs synchronously bend and straighten simultaneously with discus throwing. The throwing arm spins the projectile in the direction of its movement. In this case, the right hand and the shoulder axis should form a parallel line with the ground.
- Stop motion. During the final effort, active footwork occurs, which may prevent the athlete from stopping at the desired point. After the throw, it is recommended to stall the movement of the body with a quick change of legs during the jump or with a regular rearrangement. The right leg must be moved to the front edge of the circle so that there is no spacing beyond the line. Otherwise, the attempt will not be counted.
Currently, at official competitions athletes are allowed any technique and method of discus throwing.
History of discipline
Discus throwing was considered one of the most beloved physical exercises among the ancient Greeks. No wonder it was part of the program of the ancient Olympic Games as part of the pentathlon. Then the projectile was called the discus, and the thrower itself – discobolos. In those days, disks were made of stone, iron, copper, wood and bronze, and their weight ranged from 1.25 to 5.7 kg with a diameter of 16-34 cm.
The discipline entered the program of the modern Olympic Games in 1896, but it was only about men’s competitions. The first winner of the discus throw tournament at the Olympics was the American R. Garrett, who threw a projectile at a distance of 29.15 m. Women’s category was included in the Olympic program in 1928.
