Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
研究表明，竞走与跑步在健身方面有很多共同点，而且很可能减少受伤。然而，竞走和跑步也都有自身的问题。
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon.
But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact with the ground at all times.
It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
竞走者是训练有素的运动员。夏季奥运会最长的田径项目是50公里竞走，比马拉松长约5英里。但这项运动的规则要求竞走运动员在腿摆动的大部分时间里膝盖保持伸直，一只脚始终与地面保持接触。
马萨诸塞州塞勒姆州立大学(Salem State University)运动科学助理教授杰克琳·诺伯格(Jaclyn Norberg)说：“正是这种奇怪的形式让竞走成为一项如此吸引人的活动。”正是这种奇怪的运动形式让竞走成为一项如此吸引人的活动。
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
她说，像跑步一样，竞走对体力的要求很高，根据大多数计算，竞走者以每小时6英里的速度移动每小时将燃烧大约800卡路里(卡路里)，这大约是他们步行燃烧的两倍，尽管比跑步少，跑步每小时可能燃烧大约1000卡路里或更多。
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
诺伯格博士说，然而，竞走不会像跑步那样对身体造成那么大的冲击。诺伯格说，根据她的研究，跑步者每一步着地时身体的重量是自己体重的四倍，而不离开地面的竞走者每一步着地的重量大约是自己体重的1.4倍。
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport.
In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
因此，她说，一些与跑步有关的损伤，比如跑步膝盖，在竞走者中并不常见。但这项运动奇怪的形式确实给脚踝和臀部带来了相当大的压力，所以有过此类受伤史的人在进行这项运动时可能要谨慎。
她说：“事实上，任何想尝试竞走的人都应该先咨询教练或有经验的选手，学习正确的技术，这需要一些练习。”
