Race walking (竞走) 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(摆动) 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.
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.
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 need 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 techniques, she says. It takes some practice.

Known as the ‘Elphi’ by the locals, the Elbphilharmonie is a beautiful tower of glittering glass sitting atop an old warehouse by the banks of the river Elbe. The plaza(露天广场)is open to the public an from the middle of the city’s tallest building, you can gaze across the harbour, miles of rooftops and passing ships below.
The main concert hall seats over 2000 people and is one of the most advanced music venues in the world. Two smaller concert halls are used for jazz, world and contemporary music. In addition, if you’re unbelievably rich, you can buy one of the 45 luxurious apartments lying within the building.
Construction began in 2007 with a budget of €241 million and a two-year period. Fast forward ten years, the building eventually opened with a final price tag of over 800 million!
I consider myself very lucky that the Elbphilharmonie opened during my time living in Hamburg, but unfortunately I haven’t yet been able to attend a concert. Everything is sold out for six months! For now, I’m content to visit the plaza to enjoy the impressive view over the docks and see the innovative architecture up close. Hopefully one day soon, I’ll be lucky enough to grab a last-minute concert ticket!

【推荐2】Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its pitches (球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.
There are many environment-friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of trainers; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.
Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements (代替物) for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

【推荐3】A new app called curbi is providing parents with strong control over their children’s online activity, any time, anywhere!
Any parent of a child who has access to technology, which covers any kid old enough to point a finger, fights endless battles around proper usage, time spent and time wasted on personal devices.
Developed by a team in Western Australia, once set up, it links parents to all devices used by their kids—iPhones, iPads and iPods—so that they can direct, block or monitor their Internet time in detail.
With the touch of a button, you can put your kid’s tablet into 10 minutes of ‘Time Out’ (that’s zero Internet access), or block his or her access to social media and time-wasting apps to keep her focused during study.
The beauty of the app is that parents can set the rules (eg a ‘bedtime’ mode that allows no social media or video apps like YouTube) and apply them any time, anywhere – whether children are on the home network, or using free wifi or mobile data. It can even disable the device’s camera, photo stream and block in-app purchases, screenshots and app installations. Curbi’s most obvious application is for keeping kids safe, allowing parents to block content such as adult, TV and video sites.
The monitoring aspect allows parents to check what each of their techno children is up to on their device, at a glance—a detailed report of how many minutes are spent on each site or app can even be emailed.

【推荐1】Even though one out of three American children live within a mile of their schools, almost not half of those students often bike or walk to class, scientists report. Children who live in the South, in country areas, or who have college-educated parents, are among those least likely to bike or walk to school, which is reported in the American Journal of Preventive Medicine.
Sarah Martin and her workmates at the US Centers for Disease Control and Prevention (CDC) studied materials from more than 7,000 children between 9 and 15 years of age. They found that almost 35 percent of the children lived within one mile of their schools. Children between 11 and 13 years old were more likely to walk or bike than 9-year-olds. Children whose parents had a high school education were more likely to ride a bike or walk than children with college-educated parents.
“The majority of children are missing an opportunity to increase daily physical activity,” Martin said in a prepared statement. According to the CDC, nearly one in five (18.8 percent) children between 6 and 11 years old are overweight. Increased daily physical activity is one of the methods the CDC gives to help deal with the problem among children.
According to Martin, there are all kinds of reasons why children in city areas might be more likely to bike or walk to school. They pointed out the fact that if schools are in places where there are fewer safe sidewalks, the students will be less likely to ride or walk to school. The students should try to ride or walk to school as much as possible and parents are advised to pay great attention to their children’s health.

【推荐3】Much of our thinking about health is based on wishful thinking. But science provides clear and simple advice for a healthy life. Graham Lawton explores the evidence. Graham proves that you don’t have to be a health and fitness extremist to be reasonably healthy. He has rounded up the latest and strictest health research and changed it into useful advice on all the big health questions: diet, weight loss, exercise, sleep, ageing and so on.
Graham, New Scientist feature writer, is not the common health expert. He sometimes eats fast food. He has a gym membership but rarely uses it. And he takes medicine to keep his blood pressure under control. He neither has a diet plan nor a 6-week program to keep fit and thin.
But he does have a much better weapon: science. In a talk, Graham explains the basic science, tells people some of the secrets of science, teaches people to use the ability of judgement to tell the good from the bad, and helps them to see beyond the headlines. The talk allows people to eat healthily, lose weight, and sort the truth out from science facts.
But he loves outdoor sports. Last year Graham cycled over 1,200 miles and ran the same distance of 15marathons. He often goes swimming outdoors and walks up eight flights of stairs to his desk instead of taking the lift. He eats his five copies of fruit and vegetables a day, keeps enough water in his body, and doesn’t eat much meat. Despite all the bad habits, his good ones seem to be winning. Graham is 50, but his “biological age” was recently measured as 45.
