1 . Better grades might be found on the playground. A new study of elementary-age children shows that those who were not part of an after-school exercise program tended to pack on a particular type of body fat that can have deleterious impacts on brain health and thinking. But prevention and treatment could be as simple as playing more games of tag (捉迷藏，捉人游戏).

Most children do not meet the federal health guidelines for exercise, which call for at least an hour of it a day for anyone under the age of 18. Physical inactivity can result in weight gain especially around the midsection-including visceral (内脏的) fat, a type of tissue deep inside the abdomen (腹部) that is known to increase inflammation (炎症) throughout the body. It is also linked to heightened risks for diabetes and cardiovascular complications (并发症) even in children, and may contribute to declining brain function. Obese adults often perform worse than people of normal weight on tests of thinking skills.

But little has been known about visceral fat and brain health in children. For a soon-to-be-published study, researchers from Northeastern University in Boston and the University of Illinois at Urbana-Champaion tracked hundreds of 8-to-10-year-old children in a nine-month after-school exercise program in Urbana. Every day, one group of children played tag and other active games for about 70 minutes. The subjects in a control group continued with their normal lives, with the promise that they could join the program the following year. All the children completed tests of fitness, body composition and cognitive skills at the start and end of the program. The researchers did not ask the children to change their diets.

After the trial the exercising children who were obese at the study’s onset had less visceral fat relative to their starting weight, even if they remained overweight. They also showed significant improvements in their scores on a computerized test that measures how well children pay attention, process information and avoid being impulsive. Notably a similar effect was observed in children whose weight was normal at the start. Across the board the more visceral fat a child shed during the nine months of play, the better he or she performed on the test.

The children in the control group, in contrast had generally added to their visceral fat; this was particularly true among those who were already obese. They gained on average, four times as much visceral fat as the normal-weight children in the control group, and also did not perform as well on the subsequent test. Lauren Raine, a postdoctoral researcher at Northeastern University who conducted the study with Charles Hillman and others, says that the trial was designed to study aerobic fitness and children’s ability to think not the relation of abdominal flab to inflammation. But a reduction in overall inflammation very likely plays a role because it is thought to be unhealthy for the brain. More broadly, Raine says the study suggests that getting children to run around won’t just enhance their bodies-it might also improve their report cards.

3 . Tips to Exercise When It’s Really Hot Outside

Exercising in the fresh air might seem like a good idea.     1     When we exercise outdoors in hot weather, there’s an increased risk of serious heart-related illnesses. Therefore, we need to bear some tips in mind during our workouts in the summer sunshine.

    2     Go in the morning or evening. The middle of the day isn’t a good time to exercise in the warmer months. If we choose to exercise in the midday sun or the afternoon sun, we’ll get tired soon and dehydrate (脱水) much faster in direct, intense sunlight.     3     Just try to exercise on the shady (背阴的) side of the building to avoid the midday sun.

Drink promptly (及时地). Regardless of how fit we are, exercising outside will pose a significant danger to our body when it’s hot. Drinking water is probably the most basic part of exercising in the sun.     4     Drink water every 15 minutes when exercising in the heat, even if we are not thirsty. Aim for 2 to 4 cups (16 to 32 ounces) of fluids each hour.

Dress appropriately. Wear material that will help our body breathe. Consider wearing light colored clothing.     5     Besides, sunscreen is a must whenever we exercise outdoors. In addition, don’t forget to bring a hat because it provides shade so our head can stay cool.

A．Choose the right time to exercise.

B．Drink as much water as possible.

C．So be sure to take enough water with us.

D．That’s not to say we can’t exercise in the midday.

E．Light colors absorb less heat than darker colors.

F．Overall, the key to exercising is to listen to our body.

G．It’s dangerous, however, to exercise outside in hot weather.

Making exercise more fun

The Heart Matters magazine gives a few recommendations on how to make exercise more fun, such as asking others to join you and exercising for a specific cause, like a marathon for raising funds for an organization.     2    . But why?

Research shows that enjoying your exercise can be important for its long-term effectiveness. When you are positively engaged in something you choose to do and want to do as opposed to something you have to do, it changes your mindset. A positive mindset during exercising is absolutely essential.

    3    . You are more likely to stick to it if you enjoy it. Most people would rather make a habit of something that brings them pleasure as opposed to something boring. So, what do you find enjoyable? What is fun for you?

There are so many types of exercise

There are so many types of exercise that people can do.     4    . Running is an excellent form of exercise, as is walking. Dance classes can be super fun as well, and so can sports. Playing sports is a form of exercise that shouldn’t be forgotten.

Thinking outside the box is a must, since gyms and workouts that require lots of equipment aren’t always available or possible, and depending on these to exercise can possibly leave you without a workout at times. Team sports like basketball, tennis or football with friends are great for your fitness.     5    , or choosing other types of exercise like rope jumping, surfing, rock climbing or belly dancing. Those are all excellent forms of exercise, and your mind and body will thank you for years to come.

8 . How much physical activity do you do in a week? Are you getting enough exercise? Adults who do exercise for just 150 minutes a week can reduce their risk of serious illness by 50%. Regular exercise reduces the risk of early death by 30%.     1     Today, we are much less active than in the past. In fact many adults spend seven hours or more on a chair each day.   

    2     It means that we need to do something extra to burn more calories and use up all our energy. Adults need to do two and a half hours of moderate exercise per week. In addition, you should do exercise to strengthen muscles twice a week.

    3     Team sports such as football, rugby or cricket can be cheap because all the players share the cost of the pitch. Joining a sports club is usually a cheap way of getting exercise and can be very sociable, too.   

Alternatively, if you don't want to spend any money at all, go for a run. The only equipment needed for this is a pair of trainers     4     Go to the park. Try getting a group of friends or family together and have a game of football there.

Although adults should do two and a half hours of exercise a week, you don't have to do it all at one time.     5     If you do ten minutes before work ten minutes during your lunch break and ten minutes after work, five days a week, you've achieved the target! There are many ways of getting fit and we should all recognize the value of doing this, because we will live longer and be more healthy.

A．Divide the time into ten-minute periods!

B．You can do a range of activities to keep fit.

C．Exercise can be expensive, but it doesn't have to be.

D．This lack of regular physical activity is a big concern.

E．It also improves your mood, self-esteem and sleep quality.

F．Besides, booking a court at off- peak times saves money too

G．Similarly, getting off the bus one stop early and walking the extra distance helps.

9 . Perhaps your doctor has recommended you exercise more, or you’ve been out of shape recently.     1    . But how do you find the motivation, time and resources to get fit, particularly if you haven’t exercised for a while?

For some people, hearing bad news from the doctor is often enough motivation to get started.     2    .

However, finding the time and effort to fit exercise into your daily routine is challenging.     3    . And many people such as office workers, vehicle or machine operators have low activity levels at work and don’t feel like exercising after a long day.

One way to overcome these barriers (障碍) might be to attend a group exercise session or join a sports club.     4    , you can encourage a friend to join you or join an exercise group to make it enjoyable. Having a friend to exercise with or teammates to support you gives a sense of commitment so that you have to be there and will be challenged if you fail to show up.

You don’t need to go to a gym with a lot of fancy equipment.     5    . And rather than improving muscle strength with weights at the gym, you can fill milk bottles with water instead.

A．If you find exercise boring

B．When you perform aerobic exercise

C．Maybe you’ve decided that it’s time to lose some weight

D．That’s why it’s important to continue and repeat exercise sessions

E．We know being “time poof” is a common reason for not exercising

F．Many exercises, including push-ups and sit-ups, don’t need special equipment
