Throwing SportsIt belongs to the field competition of speed and strength, and its characteristic is that the main stage of its movements reaches the strength of the activity. The important characteristic of athletes engaged in this track and field event is to achieve the required level of dynamic exertion in a short period of time. Among all throwing events, the characteristic of javelin throwing is prominent.

The competition equipment is not very heavy (0.8 kg for men's javelin and 0.6 kg for women's javelin), and the pre run distance is longer, which helps to achieve a higher initial speed of javelin release.

The establishment of the quality of javelin throwers relies on the combination of various technical means, which help athletes achieve high-level athletic results in competitions. The javelin throwing technique includes four parts: grasping the javelin, running (pre running, throwing step), exerting force, and maintaining balance.

Hold the gun. At present, javelin throwers use two main grip methods. In one method, the thumb and middle finger lean against the edge of the rope handle, while in the second method, the thumb and index finger lean against the edge of the rope. In competitions, most athletes use a different grip method because the middle finger is longer and more powerful than the index finger. At this moment, the javelin was in the palm socket, leaning diagonally against the base of the thumb and index finger. This position can maintain a small angle between the javelin and forearm at all stages of instrument acceleration, which can be better controlled and create conditions for accurately applying force to the javelin axis.

Before starting the run-up, the athlete should bend their arm and hold the gun on their shoulder, with the tip slightly facing inward and downward.

run-up. During the run-up, transmitting the horizontal speed of the athlete's equipment system can result in an additional throw of 1530 meters compared to throwing in place. In javelin throwing, the pre acceleration phase of the equipment is completed in the form of a straight run-up (the run-up distance for men is 2535 meters, and for women it is 2028 meters), which is divided into a pre run phase and a final phase.

The pre run for male javelin throwers is 1223 meters, completed in 914 steps. The basic task of this movement and acceleration phase is to maintain a certain speed between the athlete and the overall system of the equipment. In the competition, high-level athletes run at a speed of 8 meters per second for men and 6 meters per second for women. Athletes start accelerating from the preparatory position, standing facing the throwing direction and holding a gun on their shoulder. The running speed increases continuously as it approaches the control mark, mainly by increasing the speed and stride of the running steps to improve speed.

The length of the final run is 915 meters. When we watch the competition, we find that the few steps at the end of the run-up are visually different from the previous one, and these run-up steps are called throwing steps. The number of throwing steps for high-level athletes is 46, and the specific number of steps to complete depends on the individual characteristics of the athlete.

In the first two steps of the throwing step, athletes need to complete the technical action of firing the gun. At present, there are two main ways to draw the gun: one is to draw the gun forward, then downwards and backwards; The second method is to directly draw the gun backwards. The second method is relatively simple, and in javelin throwing competitions, most athletes use this method.
In the way of completing the throwing step in four steps, step onto the marking line of the throwing step with your left foot, take a step with your right leg to start firing the gun, turn your shoulder to the right, and bend your elbow with the gun arm before firing. The hip still maintains its position and posture during the run-up. The left leg takes a step and the upper body rotates further to the right with the shoulder axis, while the gun arm extends and is pulled after the end. At this step, the shoulder axis also needs to rotate to the right.

The second to last step of the throwing step is the cross step, which is the connecting link between starting acceleration and acceleration. The athlete completes this step by actively landing the left leg on the ground and swinging the right leg with force. The active movement of both legs causes the hip axis to move forward relative to the shoulder axis. The purpose of the athlete's technical movement in this step is to create a overtaking device, causing the muscles involved in throwing to elongate in advance and creating mechanical conditions for exertion.

Apply force. In javelin throwing, 70.80% of the speed of the instrument's release relies on force, which is achieved in one throwing step. The athlete's left leg landing quickly and supporting in pairs is an important condition for effectively exerting force. In the cross step, actively push forward with the left leg and vigorously swing the right leg to tighten the body up and down, so that the left leg can quickly detach from the support and extend forward, which helps the left foot land quickly with one step.
