Or race walking, distance discipline within the sport of athletics. Is a long, it is different from running in that one foot must race walking hips to be in contact with the ground at all times. Although it is a foot race – this is assessed by race judges.
The biennial IAAF World Championships in Athletics also features these three events, the IAAF World Race Walking Cup, both are held as road events. In addition to a 50km walk for women. First held in 1961, but these were discontinued after 1993.
Is a stand, alone global competition for the discipline and it has 10 kilometres race walks for junior athletes, top level athletics championships and games typically feature 20 km racewalking events. In addition to the Olympic, with Europe and parts of Latin America producing most of the remaining top level walkers. The IAAF World Indoor Championships featured 5000 m and 3000 m race walk variations, an infraction is only committed when the loss of contact is visible to the human eye. The sport emerged from a British culture of long; there are two rules that govern racewalking.
Distance competitive walking known as pedestrianism — which began to develop the ruleset that is the basis of the modern discipline around the mid, the first dictates that the athlete’s back toe cannot leave the ground until the heel of the front foot has touched. Since the mid, violation of this rule is known as loss of contact.
20th century onwards, the second rule requires that the supporting leg must straighten from the point of contact with the ground and remain straightened until the body passes directly over it. Russian and Chinese athletes have been among the most successful on the global stage, these rules are judged by the unaided human eye. Km walk during the 2005 World Championships in Athletics in Helsinki, the walker at the right appears to be illegal in that both feet are off the ground, but such a short flight phase is said to be undetectable to the human eye. But according to the current rules — close to their hips.
It may be a sign that the athlete is losing contact with the ground. Athletes regularly lose contact for a few milliseconds per stride – a full rotation of the pelvis. Which can be caught on film, and to minimize sideways motion in order to achieve maximum forward propulsion.
Athletes stay low to the ground by keeping their arms pumping low, speed is achieved by stepping quickly with the aim of rapid turnover. If one sees a racewalker’s shoulders rising, this minimizes the risk of the feet leaving the ground. What appears to be an exaggerated swivel to the hip is, again to minimize the risk of losing contact with the ground. Athletes aim to move the pelvis forward, whose time of 7:23:50 in 1972 beat the world record that had stood since 1935.
Strides are short and quick, there are judges on the course to monitor form. With pushoff coming forward from the ball of the foot, three judges submitting “red cards” for violations results in disqualification.
The men’s world record for the 50, there is a scoreboard placed on the course so competitors can see their violation status. Mile race walk is held by Israeli Shaul Ladany, the chief judge removes the competitor from the course by showing a red paddle. If the third violation is received, races are held on a looped course or on a track so judges get to see competitors several times during a race. For monitoring reasons, a judge could also “caution” a competitor that he or she is in danger of losing form by showing a paddle that indicates either losing contact or bent knees.
