1 . Race walking shares many fitness benefits with running, research 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 (接触) 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.
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 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.
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.

4 . Before there was the written word, there was the language of dance. Dance expresses love and hate, joy and sorrow, life and death, and everything else in between.

6 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.
But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.
“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.
Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.

9 . Playing tennis regularly could help keep people off death, but football, rugby and running may not help people to live longer, a study suggests.
A study followed more than 80,000 people for an average of nine years to find out if certain sports protected them against early death. It found that people who played racket sports regularly were the least likely to die over the study period, reducing their individual risk by 47 percent compared with people who did no exercise. Swimmers also reduced their chance of death by 28 percent, aerobics (有氧运动) fans by 27 percent and cyclists by 15 percent. Yet running appeared to have no impact at all on dying early, and neither did playing football or rugby.
Scientists say the difference may lie in the social aspect which goes alongside sports like tennis and squash (壁球), which often involve clubs and organized activities outside of the game. It means that people often have larger social net-works and tend to keep up activities into later life, both of which are proven to be good for health.
In contrast, people who play team sports often do not move onto a new sport once their teams break up for family, or injury reasons. They become watchers rather than participants in their chosen activity.
The researchers found that playing racket sports was associated with a 56 percent lower risk from heart death. Similarly, swimmers lowered their heart disease or stroke risk by 41 percent, and people who took part in activities like aerobics, dance or gymnastics lowered their risk by 36 percent. But again running, football and rugby had no significant impact on heart deaths.
However, other experts argue that this study must not be misinterpreted as showing that running and football do not protect against heart disease. In this study both runners and footballers had a lower rate of death from heart disease.
