The rules of 100 meter race are introduced in detail. 100 meter race is an outdoor track and field sprint and one of the most popular and well-known track and field events. This event is very common, but few people know the detailed introduction of the rules of the 100-meter race. Come and have a look if you want to know.
100 meter competition rules specify the rules of 1 competition.
1. The athletes' track preliminaries are decided by drawing lots, and which runway is freely arranged by the computer. In the following rounds, the choice of the runway is based on the performance of the athletes in the previous round, and the final is generally determined by the preliminary results. The purpose of this rule is to make better athletes queue up on the middle runway. During the competition, the athletes go on their own tracks, and they are not allowed to cross the track after the start, otherwise the results will be invalid.
2. The squat starting and starting device must be adopted. After the password is issued, the player should immediately complete the relevant actions. Any player who fails to complete the relevant actions within a reasonable time is considered as the first foul (FS). In addition, after the password is issued, disturbing others with voice or action is considered a running foul.
3. When starting, any starting action before the gunfire rang is a starting foul. Starting from 20 10, it is stipulated that there is only one starting opportunity (starting without starting or starting within 0.02 seconds after starting). The first starting must be re-started, and the athletes who start again will be disqualified and re-started.
4. The ranking of all runners in the competition depends on the order of their trunks (excluding head, neck, arms, legs, hands or feet) when they reach the finish line and the vertical plane, and the first runner ranks first. If the result is the same, the athletes concerned should enter the next competition. In the final, the first place has the same score, and the referee has the right to decide whether to play again. If there is an unconditional rematch, tie for first place. As for other rankings, the results are the same and will be processed in parallel.
100 meter race rules detailed introduction 2 What is the standard of track and field line collision?
Line collision means that at the last moment of the race near the finish line, the chest or shoulder quickly leans forward to the vertical plane behind the finish line and then crosses the finish line.
It is necessary to press the line forward, and the chest or shoulder moves quickly to the vertical plane behind the finish line.
It is not allowed to cross this line or any other part of the body.
In track and field competitions, all running events (including hurdles and relay running) belong to track events. The ranking of contestants depends on the order in which their trunks (different from their heads, necks, arms, legs, hands or feet) reach the vertical line within the finish line.
In a running race, which part of the body touches the line is the result.
Based on the end point of head or chest impact. If there is a dispute, the general sports meeting will have a referee who focuses on ranking, and the large-scale sports meeting will also have a video of sprinting the finish line. The ranking judges will be supplemented by timing judges or photos decided by the Arbitration Commission. Track events determine the ranking of athletes through time. From the initial use of the stopwatch to the later use of the camera, the result can be accurate to one hundredth of a second. Nowadays, the computer timing system used in international competitions can make the results accurate to one thousandth of a second.
With the slogan of higher, faster and stronger, the achievements of contemporary track and field sports have developed to the point where they cannot be interpreted with the naked eye. Excellent sprinters have a high speed in the 100 meter race. When they cross the finish line, they can't judge and reflect their rankings and achievements with the help of human eyes and nervous system. Carl lewis and M, famous sprinters, once reached the maximum speed 12 m 05/ s in the100m race. In high-level competitions, the performance of top sprinters is only 0.0 1 sec. When they reach the finish line, we can't judge who is the first, just like Liu Xiang and Johnson's 13.06 seconds in golden league, Rome. At that time, it was almost at the same time. Finally, our camera system told us that Johnson was in the lead. Especially in such an important competition as the Olympic Games, whoever wins the gold medal and who comes first must have a basis, otherwise it will be difficult to explain to the athletes! With the development of achievements and the progress of science and technology, we have a fully automatic track and field finish photography timing system.
This system makes a reasonable judgment on our achievements and rankings. When the referee shouted "Take your positions", the starting system started to work, and when the "ready" athletes started to do the starting action, the preemptive system started to work, telling the referee that several athletes started early in milliseconds. Generally speaking, when the starting device receives more than 25 kilograms, it is judged as a preemptive strike. When the starting gun rings, the timing system starts to work and time. When the athlete runs about 10 meters away from the finish line, the finish camera starts to turn on, ready to shoot. When athletes cross the finish line like a swarm of bees, the camera takes pictures of them crossing the finish line, and then uses the finish line score interpretation system to determine the athletes' rankings and final scores to three decimal places, but the final announcement only tells everyone the last two digits, such as 65438+. Athletes who hit the line almost at the same time use three decimal places to decide the final ranking.
According to IAAF regulations, athletes' official achievements and record-breaking only recognize electric timing results. When the athlete breaks the record, the final photo should be kept for final verification. Electronic timing system has been used in international competitions now. China's IAAF stipulates that the electric timing system must be used in more than three competitions in the country. Sprinters must be identified by electronic timing.
At present, Omega in Switzerland and Seiko in Japan are both electric timing systems approved by IAAF. Swatch in Switzerland, one of the sponsors of the International Olympic Committee, is used for the Olympic Games. The system can record the segment time and maximum speed of the athletes during the competition, and display the final result 15 seconds after the competition. In addition, China uses an electric timing system produced by Kunming Institute of Sports Electronics.
Science and technology are the primary productive forces, and advanced science and technology serve mankind everywhere. Therefore, the theme of our Beijing Olympic Games is "Hi-tech Olympics".
100 meter competition rules detailed introduction 3 100 meter sprint skills
1, go
The departure process includes three stages: "take your positions", "prepare" and "fire your gun". After hearing the "take your positions" password, squat down, put your hands and fingers together, put your thumb on the back edge of the starting line in a figure of eight, and step on the front and rear starters in turn, with your feet close to the starter and your toes touching the ground. The back and neck are naturally relaxed, the arms are straight and shoulder-width, and the hind legs and knees support the body. After hearing the "prepare" command, the hips are raised to shoulder height or slightly higher, the shoulders slightly exceed the starting line, the weight mainly falls on the arms and front legs, the front and rear calves tend to be parallel, and the feet touch the pedals near the starter. The whole movement needs coherence, coordination and strength, and attention is highly concentrated. After hearing the gunshot, the hands are quickly pushed off the ground, the elbows of the two arms bend and swing back and forth, the two legs push the starter in turn to make the body move forward and upward, the hind legs bend forward and upward quickly, and the front legs push the three joints of hip, knee and ankle quickly and forcefully, and the body moves forward in a larger forward posture.
2. Accelerate running after starting.
Accelerated running after the start is a running period from hind legs to midway, which is generally about 25 ~ 30 m. After the start, the two arms swing hard, and the swing range is large. The legs alternately push and stretch hard, the step length gradually increases, the step frequency gradually accelerates, the landing place of the two feet is gradually in a straight line, and the upper body gradually rises, naturally entering the way to run.
Step 3 run on the road
The task of running on the way is to continue to play and keep high speed to the finish line. Running is a periodic activity. In a running cycle, it includes back push and forward swing, flying, landing buffer and other action stages.
(1) Backward push and forward swing stage: When the body's center of gravity moves past the vertical plane of the fulcrum, it enters the backward push and forward swing stage of kicking. At this time, the knee joint of the swinging leg (thigh folding posture) begins to surpass the supporting leg, and quickly and forcefully swings forward and upward, driving the ipsilateral pelvis forward, and the thigh forms an angle of about15 ~ 20 with the horizontal plane. This is the key to running.
(2) Vacation stage: When the support is completed, that is, when stepping into the levitation stage, the calf will quickly move closer to the thigh with the inertia after stepping on the ground and the swing of the thigh, forming the action of folding the big calf and swinging forward. At the same time, the swinging leg actively presses down with the hip joint as the axis, the knee joint relaxes, and the calf naturally stretches forward and downward with the inertia of downward swinging, ready to land.
(3) Landing buffering stage: When the forefoot of the swinging leg touches the ground, the landing buffering stage begins. The landing position is about one and a half feet away from the projection point of the body center of gravity, and the landing action should be very positive. The cushioning process of each joint of the leg (especially the ankle joint) should not be negative, but should be actively exerted to accelerate the forward movement of the body's center of gravity, and then turn to the back pedal. When running on the way, your head is straight and your upper body leans forward slightly. The arm swings back and forth naturally, briskly and forcefully with the shoulder as the axis.
Step 4 finish running
The finish running includes two stages: the final exertion and the upper body hitting the line before the end of15 ~ 20 m. The technique of the finish running is to keep the upper body leaning forward, speed up the swing speed and strength of both arms, and maintain or exert the maximum speed. When you are one step away from the finish line, your upper body leans forward quickly and hits the finish line with your chest or shoulders. After running through the finish line, it will gradually slow down and never stop.
