1 . For people suffering from depression, there’s an all-natural treatment they should use — getting more exercise. It could help fight depression, even if people have a genetic risk, new research shows.
For the study, researchers collected information from nearly 8,000 people and found those with related genes were more likely to have depression over the next two years after examining them. But that was less likely for people who were more active at the study’s start, even if they had a family history of depression. Higher levels of physical activity helped protect even those with the highest genetic risk of depression.
Both high-intensity (高强度) exercise and low-intensity activities were associated with a reduced risk of depression. Adding four hours of exercise a week could lower the risk of a new episode (一段经历) of depression by 17%, according to the study. “Our findings strongly suggest that, when it comes to depression, being physically active has the potential to remove the added risk of future episodes in individuals who are genetically risky,” said lead author Karmel Choi. “On average, about 35 additional minutes of physical activity each day may help people to reduce their risk and protect against future depression episodes.”
Depression is a common mental illness globally, with more than 264 million people affected. “Depression is so ubiquitous, and that underlines the need for effective approaches that can impact as many people as possible,” Choi said. And mental health and primary care providers can use the findings to advise patients that there’s something meaningful they can do to lower their risk of depression.

2 . Soccer, basketball, baseball, and the like are popular all around the world, However, do you look for something a bit different? There may be some new sports that you want to try out!
One of the new sports is regball. It is a Russian sport adding basketball, wrestling (摔跤) and rugby. As in basketball, the players have a ball that they try to shoot through a hoop (篮筐) . But nobody will be calling “that’s a travel” while watching this sport, because there is no need to dribble (运球) . Players also wrestle with each other during the game.
Another kind of sport you don’t see every day is soapbox racing. Handmade vehicles are pushed down a hill, and competitors have to drive their vehicles through a course with different kinds of things in their way. Not all competitors are engineers, so the vehicles are easy to break apart. Competitors are judged for their soapbox’s creativity. Therefore, speed is not everything, and creativity plays the most important role. Competitors often design their vehicles based on themes from pop culture or history. Of course, the competitors dress up to play the role, too.
Cheese rolling race is not seen very often, but it is exciting. This is a game that is extremely funny for audience, but painful for competitors. During the game, competitors race down a very steep (陡峭的) hill, chasing after a round of Double Gloucester cheese that can weigh up to nine pounds and can travel some 70 miles per hour. Whoever gets to the bottom first wins the cheese.

5 . 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.

6 . The benefits of regular exercise are well documented but there’s a new bonus to add to the ever-growing list. New researchers found that middle-aged women who were physically fit could be nearly 90 percent less likely to develop dementia in later life, and as they did, it came on a decade later than less sporty women.
Lead researcher Dr. Helena Horder, of the University of Gothenburg in Sweden, said : "These findings are exciting because it’s possible that improving people's cardiovascular （心血管的）fitness in middle age could delay or even prevent them from developing dementia. "
For the study, 191 women with an average age of 50 took a bicycle exercise test until they were exhausted to measure their peak （最大值的） cardiovascular capacity. The average peak workload was measured at 103 watts.
A total of 40 women met the criteria for a high fitness level, or 120 watts or higher. A total of 92 women were in the medium fitness category; and 59 women were in the low fitness category, defined as a peak workload of 80 watts or less, or having their exercise tests stopped because of high blood pressure, chest pain or other cardiovascular problems.
These women were then tested for dementia six times over the following four decades. During that time, 44 of the women developed dementia. Five percent of the highly fit women developed dementia, compared to 25 percent of the women with medium fitness and 32 percent of the women with low fitness.
"However, this study does not show cause and effect between cardiovascular fitness and dementia, it only shows an association. More research is needed to see if improved fitness could have a positive effect on the risk of dementia and also to look at when during a lifetime a high fitness level is most important. " She also admitted that a relatively small number of women were studied, all of whom were form Sweden, so the results might not be applicable to other groups.

7 . People need to relax and enjoy themselves. One way they can have a good time is to watch a baseball game or another sports event.Even thousands of years ago，groups of people gathered to watch skilled athletes(运动员)．
Over 2，000 years ago in Greece，certain days in the year were festival days. These were holidays when people stopped work and enjoyed themselves. They liked to watch athletes take part in races and other games of skill.
The most important festival was held every four years at the town of Olympia. It was held in honour of the Greek god Zeus. For five days，athletes from all parts of the Greek world took part in the Olympic Games. At the Olympic Games，people could watch them box，run，jump and so on. There was a relay race between two teams of men in which a lighted torch(火炬) was passed from runner to runner. The Olympic Games were thought to be so important that cities which were at war with one another had to stop fighting. People were allowed to travel to the games freely. Thousands of people came to Olympia from cities in Greece and from its colonies(殖民地) in Africa，Asia and Italy. They met as friends to cheer their favourite athletes and to enjoy themselves.
