Race walking shares many fitness benefits with running, rearch shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
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 exerci science at Salem State University in Salem, Mass.
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(卡路里) 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.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her rearch, 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.
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 for m 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.

According to a recent study in the Journal of Consumer Rearch, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing rearch that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.

To test the effect of social influence on eating habits, the rearchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herlf to a snack. An actor hired by the rearchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cas she wore a specially designed fat suit which incread her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit,
taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the cond test, in one ca the thin actor took two pieces of candy from the snack bowls. In the other ca, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If th is fellow participant is going to eat more, so will I. Call it the “I’ll hav e what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit becau I e the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?
