Discus Throw - Overview
There are many games under the umbrella of track and field event. Discus Throw is one of those games played solo in competition with other players.
Discus Throw – A Brief History
Discus Throw can be traced back into the ancient Greece, where in the Olympiad games this sport was used to be organized to judge the physical strength of the athletes. This game was also popular because it requires high precision and coordination. During that time it was believed to be one of the easiest sport events.
Some eminent historic proofs shows that the trace of this game was found during the period of 708 B.C. soon after its addition into 18th Olympiad games it was also introduced into pentathlon games that included wrestling, running, javelin throw, and jumping. According to the facts of Perseus digital library, earlier times the discus used to be made up from stones, bronze, or iron.
Discus Throw – Objective
The athlete needs to throw a discus of 1 to 2Kg into the air as far as possible within the prescribed zone by remaining inside a circular area of 2.5m diameter. If the discus lands beyond the boundaries of the zone then the throw is counted as invalid.
In this game the athlete needs to hold the discus in his hand with proper placement of fingers. By standing in a circular zone and facing towards the discus-throwing area, the athlete spins around oneself to gain the momentum and finally throws the discus in the air.
Discus Throw – A Game of Projection
Discus throw demands high physical strength and more importantly, one’s balance upon one’s body since weight of the discus, the grip on the discus and precise circular movement around oneself involved matters the most.
The player needs to deliver a fixed number of throws out of which the best score is considered. The player who throws the discus farthest among all competitors is declared as a winner. This projection game is played in both men’s and women’s category.

Discus Throw - Playing Environment
While playing Discus Throw, the player launches the discus from a circular area by turning around oneself for one and a half turns. The playing environment of discus throw mainly includes the following −
- Throwing circle
- Landing zone
Let us discuss each of them in detail.
Discus Throw – Throwing Circle
Also called Discus Circle, it is the area within which the player needs to take a start and complete the throw. It is made of iron, steel or other suitable material such as hard rubber sheet. The top of this circle is aligned horizontally with the ground outside the circle.
The measurements of throwing circle are as follows −
Inside diameter = 2.5m (±5mm)
The throwing circle rim = at least 6mm thick, and 70mm to 80mm deep.
The rim is always painted white for the purpose of demarcation. The interior of the throwing circle is made of concrete or some non-slippery material. The surface of the throwing circle is even and 1.4cm – 2.6cm lower than the rim of the circle.
Discus Throw – Cage
The U shaped cage offers protection for the viewers. It is designed and manufactured such that it can take the load of misthrow of the discus of 2Kg flying at the speed up to 25m per second. Any strong material that offers protection for the player from rebounding the discus can be used for the cage.
Generally, the netting of cage is constructed from synthetic fibers or steel wire of moderately high tensity.
The cage measurements are −
- Width of the mouth is 6m

Mouth of the cage is positioned 7m in front of the center of the throwing circle.
Discus Throw – Landing Zone
The landing zone (also called landing sector) is where the discus arrives after the player throws it. The landing zone’s surface must be capable of taking the impression of the discus upon its landing. It is made of natural grass or other suitable material without any bumps.
The landing zone is laid at an angle of 34.92° with respect to the middle of the throwing circle. It is marked by 50mm wide white lines. The landing zone is 80m long.
Discus Throw - Equipment
Discus throw game is not equipment-heavy. You just need a couple of things to play the game. The discus throw equipment are available for amateur as well as for professionals.

You can achieve real power when you touch the ground with the left foot.
During this time position, your left arm in the direction of the throw.
Complete the pivoting of the right foot.
Brace the left side of your body now.

Discus Throw - Techniques
The rules or the bottom lines of the game also make performance assessment of the participants easy.
Throwing the Discus to Optimum Distance
As of now, you must have already known that Discus Throw is the game of distance. You have to throw the discus so that it will reach up to targeted area. The distance covered by the discus depends upon many factors but the following factors are most important −
- The speed with which the discus is thrown.
- The height from which it is released.
- The projected angle.
Among the above three, it is the speed that dominates the other two factors while deciding the actual distance covered by the discus.
Keeping Optimum Release Angle
The ultimate angle with which an athlete releases the discus in the air is known as Optimum Release angle.
With the case of ballistics, the initial speed applied to all the projectiles is more or less same irrespective of their angle of projection. The optimum releasing angle range used by most of the successful athletes varies in the range of 38°±8°.
But it is also a fact that the releasing angle and speed of throw are inversely proportional to each other. That means, if the angle of release is increased, the speed of projection decreases and vice versa. However; the speed decreases due to the following two main factors −
With the increase angle of projection, you require more energy to overcome the weight of the discus and hence less energy will be available with you to generate more speed.
With increase in the release angle, the speed decreases.
By making a unique combination of releasing angle and the velocity with which the discus is released, every player comes up with a different throwing style. It depends upon again various factors such as −
- Size of the player’s body
- Strength of the player’s body
- Stamina of the player
- Techniques of discus throwing
