Race walking is a sport developed from everyday walking, what are its benefits?

Competitive walking is developed on the basis of ordinary walking, both have the same movement structure, both are supported by a single foot and double foot support alternately repeated. However, race walking has its own characteristics, the pelvis rotates back and forth, the waist has a certain twist, the two arms swing actively, the leg is fully extended when the foot hits the ground, the stride length is large, the frequency is high, and the forward speed is fast.

Practicing race walking can develop the strength of the leg muscles and hip joint flexibility to enhance physical fitness, promote health, improve the blood circulation system and respiratory system function, cultivate hard work and stand hard, courageous and tenacious quality of will. The speed of walking depends on the step frequency and step length. Ordinary walking per minute is about one hundred to one hundred and twenty steps, and race walking up to one hundred and eighty to two hundred steps, excellent race walking athletes more than two hundred steps per minute. The length of a normal walk is usually seventy to eighty centimeters, while the length of a race walk can be ninety to one hundred and ten centimeters, and the step of a tall athlete is about one hundred and twenty centimeters.

Ordinary walking, each step generally need 0.50-0.55 seconds, while the competition walk each step only need 0.27-0.32 seconds, or even less. This therefore increases the degree of difficulty in alternating muscle tension and relaxation work and needs to be addressed well in training.

Step length and stride frequency are constraints on each other. Increase the step length relatively will affect the step frequency, accelerate the step frequency will also affect the step length. Generally should ensure a certain step length under the premise of increasing the step frequency. Excessive increase in stride length, will give the relevant muscles to increase the burden and increase the degree of tension, excessive consumption of physical energy, easy to cause fatigue, but also not conducive to the acceleration of stride frequency. Accelerating the stride frequency is relying on the strength of the leg muscles and the role of the central nervous system, its potential force is relatively large.

The refereeing work of the racewalking competition is an important link to ensure the smooth running of the competition. Generally speaking, the world-class competition, usually arranged 9 referees, standing in different areas of the competition site "law enforcement". These referees are appointed by the International Association of Athletics Federations (IAAF) and must have the qualification of international referees. China's race walking referees are often added to the refereeing work of the World Championships.

The most interesting part of the refereeing work in race walking is the presentation of the red card. In the World Championships, including the Olympic Games, athletes are often penalized with red cards when they are far ahead of the competition.

According to the IAAF's rules on race walking, if an athlete is shown three red cards in a race, the athlete is penalized. However, the three red cards should be shown by three judges, and the rules stipulate that any one judge can only show one red card to an athlete in the same match.

The rules of the racewalking competition have a lot of detailed provisions on the technology and behavior of the athletes in the competition, the most important two of which are that the athletes can not compete with both feet in the air, and can not bend the knee when the supporting leg is on the ground, and so on.

Chinese race walkers were often penalized with red cards in world competitions for technical reasons. In recent years, China Race Walking has especially emphasized on grasping technical details, especially in the late stage of the competition. During this period, athletes enter into a period of fatigue and the competition is intense, which has a greater impact on the technology, and it is easy for them to have technical deformation and eat the red card. After these years of efforts, Chinese race walker technology has improved, the year before last and last year in the World Cup, the Olympic Games and other competitions have achieved excellent results.

Finally. Good luck practicing for the gold medal.
