In modern competition the discus must be thrown from a circle 2.5 metres (8.2 feet) in diameter and fall within a 40° sector marked on the ground from the centre of the circle. Discus throwing is a performance of high speed movements within a limited space, with the final release speed playing are primary role in the distance the discus is thrown (Dai, et al., 2013). As a result, the discus reaches zero velocity at the beginning of the turns then increases gradually during the turn until the release phase, which means that the shorter the duration of the turn the greater the velocity of release is (5). Each phase will illustrate the definition, injury occurrence rate, and lastly pathological possibilities. The surface must be covered by some kind of non-slip material. The technique of the discus throwing consists of the preliminary swings, the preparation, the entry, the airborne, the transition, the delivery and the recovery (Bartlett, 1992). Some athletes will throw in a fixed foot position with both feet remaining on the ground for the duration of the delivery. In 1896 it became one of the main sporting events at the Olympic Games. provide three-dimensional (3D) footage for the analysis of all key phases of the discus throw. the turn across the circle, Keep left arm over left leg (as if reading the time), When driving across the circle and turn out this should provide the power house position for the throw, Keep the right foot turning throughout the throw and allow the left leg to come underneath the body and ground. Then, he must throw the ball with his arm completely stretched out by a quick movement.

SHOT PUT. i.e. Modern Commun 2014; 42: 130. Team Singapore's James Wong before releasing the discus at the SEA Games 2013 (photo credit: Stanley Cheah/SportSG). Athletes throw at different speeds and are unable to have the same speed at all optimumprojection angles. After the final competition a calibration procedure was conducted to capture the performance volume. Incorrect discus grip. Thrower must have balance for good rhythm. above mentioned phases as useful information concerning the technique of the discus throw. For this reason, it is advised for the novice to develop the linear technique and progress to the rotational technique at a later stage, if needed.

Discus Throw For positioning, 12 o’clock is used as the front of the circle Preparation of the throw The start and the wind up are critical to set up the throw. related to discus throw during each phase of Despite of these parameters determine directly performance and comparing it with the specific the projected distance of the throw; they didn’t kinematical variables in each phase in the give any indication to phases leading up to national champion with elite athletes. Research on the technology training of discus throw based on the sports biomechanics. Phases of the Discus Throw 4. The disc used by men must have a weight of two kilograms and a diameter between 219 and 221 millimeters, at the same time its thickness must be between 44 and 46 millimeters in its flat part. However he did not consider the influence of the angular momentum of the system about the right-left (X) axis (vertical to the direction of throw) on the velocity of the discus. Results: The EMG activation of LD lasted longer (p < 0.01) in P1 and was initiated later in P5 with the LGT discus compared to STD.

The Grip: Most throwers opt to have the fingers evenly spread and the last joints placed on the rim of the discus. When the thrower starts the throw, his weight should be equally distributed over both the right and left legs as he performs a wind-up with the discus to gain a little momentum to start the throw.

The incorporation of this discipline took place in Athens in 1896, and women joined the competition in 1928, during the Olympics in Amsterdam.

Each competitor may throw the disc three times while he is in the knockout round and then, three more shots in the final round. The performance of a discus throw is measured by official distance, which is the sum of vacuum flight distance, aerodynamic distance, and distance lost at release (Bartlett, 1992;Hay & Yu, 1995). wind up (see below) cocking.
