1 . 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.

2 . The reasons skiers and snowboarders wear goggles or glasses might seem a little obvious, especially if you’ve ever hit the slopes yourself. Sunlight reflected off the snow can make it hard to see, and UV rays can even damage your eyesight. Special colored lenses also create contrast, so your whole path won’t look like one flat expanse of whiteness.    1    

Olympic speed skaters, meanwhile, are racing inside on smooth ice.     2    

According to NBC Olympics, glasses can increase visibility on indoor tracks, too.     3     And while the ice may look smooth from a distance, those sharp blades can kick up ice chips that could pose problems if they end up in your eyes. In the event of a crash, shatter-proof glasses also protect skaters’ eyes from errant blades and body parts.

    4     Shot-track speed skaters (who race around a roughly 11-meter track) can go as fast as 30 miles per hour or more, and long-track speed skaters (whose track is 400 meters long) sometimes hit about 35 miles per hour. The wind resistance generated by such speed- in a chilly arena—is enough to make any skater’s eyes start streaming with tears. Picture leaning your head out the window of a car that’s going around 35 miles per hour on a cold day: You’d probably want to be wearing glasses, too.

That said, glasses aren’t a requirement.     5     Belgium’s Stijn Desmet, for example, has raced in Beijing 2022 Olympic Winter Games without eyewear, as has China’s Zhang Chutong.

Chessboxing is a sport which     1     punching power with mental power. There are 11    2     in all, with one round of chess and then one round of boxing.     3     are those whose mental    4     equals their physical power. People usually think that boxers aren’t clever, which is not     5     true. The sport     6     that boxers can be smart and smart people can be tough.

In the boxing ring of in a Berlin Club, a boxing match is on. Frank Stoldt, a strong German, is seated at a table, and beside him is his opponent, a     7     American boxer. For     8     reasons, the crowd is on Frank’s side, for he is a local player. Before the match started, Frank spent hours     9     his mind and muscles. And as a result of luck and hard work, the local hero checkmates his opponent and     10     the world title belt.

7 . Is there a way to turn back the clock on your age? A new study says yes. Exercise can make you look younger. At least it can lower your fitness age—that is the measure of how well your body works.

A study of athletes in the National Senior Games found that their fitness age was more than 20 years younger than their chronological age. The games took place in the Midwestern state of Minnesota.

Tony Diamond took part in the games. Every morning he went to a local park and walked fast for an hour. Then, the retired navy captain ran for an hour.

Two or three times a week, he went to a gym for muscle(肌肉) training. Mr. Diamond won three medals at the 2015 National Senior Games.

“My current age is 86 years old, and my fitness age is 44. I think I am in such good physical condition because I do a lot of exercise during my life. I have been exercising since I was a little boy,” said Mr. Diamond.

“I'm 62 years old and my fitness results showed that I was 32 years,” said Ms White.

Ms. White and Mr. Diamond are some of the 5,000 Senior Games participants who took part in the fitness age study.

Pamela Peeke was an assistant professor of medicine at the University of Maryland. She worked on the study with Ulrik Wisloff at the Norwegian University of Science and Technology. Mr Wisloff developed a fitness calculator.

An online calculator is available for anyone to use for free. Ms. Peeke says there are benefits from attending this test.

The National Senior Games take place every two years. They are the competition for athletes older than 50. The games include a variety of sports.

This year the average age of the people competing was 68. But their average fitness age was 43.

9 . I have read with interest the opinion of one woman who attended a high school basketball game at Three Oaks and came away thinking the students were disrespectful. I have a very different point of view. Respect does not equal quiet, although a certain generation of people would disagree. Respect is a deep admiration for someone or something because of their abilities or achievements and a regard for the wishes and traditions of others.

In my opinion, the students at Three Oaks High School were the very picture of respect. They brought their team and school spirit to show their admiration for their basketball team. This is something that is desperately lacking in many schools — SPIRIT. I am so happy to say it is alive at Three Oaks. They cheered and made noise in a gymnasium, they jumped up and down when their team scored, they groaned when they made mistakes, but kept the team's spirits up by cheering, even when it was evident, they were going to lose. They kept the tradition of cheering and respect by showing due regard to a parent who came over and spoke to them about jumping too far onto the court. They listened and followed his instructions. He also happened to be the coach of another team whose fans were doing nothing.

These kids were doing what they were supposed to do, in a place they were supposed to do it. It was not a library, or a mall; it was a sports match. I would ask the lady who wrote the letter to the editor if she has been to any professional sporting events? I remember watching a Super Bowl I a few years ago and the quarterback could hardly make his calls heard to the guy standing right in front of him. You know what he said about it later, that it was amazing to have the fans cheering so loud.

I wish both these teams the best of luck. It was an amazing game. Even though we lost, we left with our spirits high, ready for the next time our teams me. It is going to be another great game of basketball.
