3 . The Growing Popularity of Cycling

They say once you learn how to ride a bike, you never forget. Most of us learnt when we were kids, and many still strap (系好) on our helmets, put our feet on the pedals , and shoot off for a ride around the streets. In recent times, cycling has seen a boost in popularity.     1    

First, let’s look at the health benefits. Cycling can improve your cardiovascular (心血管的) health and burm excess body fat. Strengthening your leg muscles in your calves (小腿肚) and thighs (大腿).     2     A long ride in the countryside could help you to clear your mind, or de-stress. But it’s not only about your body and mind— there are also some plus sides for your wallet’s health.

Cycling can be a great way to commute (通勤) or get about town.     3     If you do drive into work, sometimes finding somewhere to park can be a nightmare, whereas finding somewhere to chain your bike up can be much simpler. Then, on the train, there are changes at stations and other commuters speaking loudly on their phones to deal with. And if you’re worried about safety, there are designated cycle lanes in many major cities. Wearing high-visibility clothing is another way to improve your safety when cycling on the roads.

    4     It can help you to reduce your carbon footprint. Not pumping out fumes into the atmosphere is better for the planet and your own environment.

So, whether people want to cycle for their health, getting about town, their wallet, the environment, or a combination of all of them—    5    

4 . As we age, even if we’re healthy, the heart just isn’t as efficient in processing oxygen as it used to be. In most people the first signs show up in their 50s or early 60s. And among people who don’t exercise, the changes can start even sooner.

“Think of a rubber band. In the beginning, it is flexible, but put it in a drawer for 20 years and it will become dry and easily broken,” says Dr. Ben Levine, a heart specialist at the University of Texas. That’s what happens to the heart. Fortunately for those in midlife, Levine is finding that even if you haven’t been an enthusiastic exerciser, getting in shape now may help improve your aging heart.

Levine and his research team selected volunteers aged between 45 and 64 who did not exercise much but were otherwise healthy. Participants were randomly divided into two groups. The first group participated in a program of nonaerobic (无氧) exercise—balance training and weight training—three times a week. The second group did high-intensity aerobic exercise under the guidance of a trainer for four or more days a week. After two years, the second group saw remarkable improvements in heart health.

“We took these 50-year-old hearts and turned the clock back to 30-or 35-year-old hearts,” says Levine. “And the reason they got so much stronger and fitter was that their hearts could now fill a lot better and pump (泵送) a lot more blood during exercise.” But the hearts of those who participated in less intense exercise didn’t change, he says.

“The sweet spot in life to start exercising, if you haven’t already, is in late middle age when the heart still has flexibility,” Levine says. “We put healthy 70-year-olds through a yearlong exercise training program, and nothing happened to them at all.”

Dr. Nieca Goldberg, a spokeswoman for the American Heart Association, says Levine’s findings are a great start. But the study was small and needs to be repeated with far larger groups of people to determine exactly which aspects of an exercise routine make the biggest difference.

5 . Skiing has been around since early civilization, evidenced by a 5,000-year-old rock carving representing men on skis hunting deer in Norway, and the discovery of a ski dating back to 6000 B.C. found in Vis, Russia. Historians debate where skiing first got its start, though; some argue that it was in Altay, China, in 8000 B.C.

Modern skiing, however, can date back to the Scandinavians, who mainly used skis as a means of travel or for other practical purposes, particularly the Indigenous Sámi people in Norway, Finland, and Sweden, writes Raymond Flower in The History of Skiing and Other Winter Sports. Norse myths (挪威神话) even described Ull, a winter god, on skis with curved tips and included other stories of heroes and goddesses skiing down mountains.

Some of the first official competitions began around 1850 in Norway, with the first recorded race in Sweden held outside Stockholm in 1879. Skiing became a household word with the publication of the popular book offering a thrilling account of Norwegian explorer Fridtjof Nansen’s difficult and historic journey on skis across Greenland in 1888.

The sport spread to the Swiss Alps, where it was enjoyed largely by British vacationers, before clubs popped up around the world in the late 19th and early 20th centuries. Variations of the sport developed over the years, such as the slalom race (障碍滑雪), downhill jumping, and mountaineering. The British are largely credited with transforming skiing from its Scandinavian roots into the highly competitive sport it is now. In 1921, they developed rules that became widely accepted and adjusted the slalom race to include flag gates to test the skill of skiers’ turns.

Skiing then exploded in popularity after World War II, when ski resorts (胜地) gradually developed to receive single-day skiers as well as those taking longer vacations.

8 . The Importance of Getting Kids to Be Active

Everyone knows that kids should be physically active and need to exercise regularly to be physically fit.     1    , regular physical activity is considered by most experts to be an important part of a healthy lifestyle. However, that doesn’t mean every child needs to spend four or five hours a day exercising.

How Much Exercise Do Kids Need?

It is recommended that kids should be physically active for at least 60 minutes per day.     2    . For example, if your eight-year-old played soccer for 20 minutes during PE at school and then played basketball with his friends for 40 minutes after school, he would meet the recommendation of 60 minutes of physical activity for that day.

Exercise and Calories

    3    . It can help them build self-respect, sleep better, have more energy, and reduce depression. And as most people know, along with a healthy diet, regular exercise is the best way to lose weight and prevent childhood obesity (肥胖). Since your child is not likely to get his exercise using exercise equipment, it can be hard to always tell how many calories he is burning while exercising.     4    , as long as your child is getting his 60 minutes or more of physical activity each day and maintaining a healthy diet.

Youth Exercise and Fitness

Remember that kids, even teens, don’t usually stick with exercise programs.     5    . Instead, kids do better with lifestyle exercise programs, such as active free play and organized team sports.

9 . Nowadays, in many places of the world, kids play soccer less than before.     1     Besides, many parents don’t know soccer’s real help to kids. Here are some reasons why kids should play the beautiful game.

Soccer is a team sport.

Teamwork is a life skill that kids need to learn. Being part of a team isn’t just about learning how to work together and share talents. It’s also about teaching kids how to face failure. It doesn’t end there, either. Being part of a team lets kids know how to take responsibility for their behavior.    2    

Soccer shapes motor skills (运动技能).

Nowadays, many kids prefer to stay in their rooms to have fun through TV, video games and smartphones.    3    It can cause them to lose out on valuable motor skills. By playing youth soccer, kids get a chance to develop their physical strength and motor skills.

    4    

Soccer can improve students’ concentration (专注) in the classroom. Besides, soccer is a fast-paced game, so kids can learn how to solve problems quickly. Plus, soccer is a sport which involves getting the ball from point A to point B. So kids’ visual-spatial (视觉空间) ability can be improved when they play the game, which can help them learn subjects like Physics.

Soccer improves the personal character.

The World Health Organization recommends kid get at least 60 minutes of exercises daily. This isn’t only for the physical benefits but also for the benefits to the personal character.     5     And these kids often have more self-confidence.
