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.

3 . It can be incredibly difficult to encourage ourselves to go for a run during winter, particularly when it’s wet and windy outside. But new research has found that even a super-quick run could have great health benefits. In fact, it seems that just a 10-minute session will not only make us feel better, but could actually improve brain health, too. Now, we all know that exercise can improve mental and physical health in many ways.

But when it comes to mental well-being, there’s been relatively little research done on the specific benefits of running, compared with other physical activities, such as cycling. So this was something put to the test during a recent study. Researchers from University of Tsukuba in Japan asked participants (参加者) to run on a treadmill (跑步机) for just 10 minutes. They then had to take a Stroop Color and Word Test which is used to measure reaction time in brain processing. Results showed there was a highest point in self-reported pleasure and an increase in degree of activity of the brain.

In other words, runners were found to have an increase in blood flow in the part of the brain that’s associated with dealing with functions and controlling mood (情绪). Researchers then compared these results to a similar study on cycling, which also showed improved cognition (认知), but no mood improvement. Therefore, it seems various types of exercise can make us feel differently.

The authors noted, “Given exercise is medicine, the effects of drugs differ depending on the type of drug, and different types of exercise such as running and cycling should be observed to have different effects on mental health and brain functions as well.”

So pushing ourselves to get outside for a run really will make us feel better, probably more than other fitness activities. And these findings show that we don’t necessarily need to do a lot of exercise to feel the benefit of it.

4 . How to Determine the Best Time to Exercise

Any time of the day you can spend to exercise is a good time for getting active.     1     Consider your lifestyle and exercise goals to help find the right time for you.

You should determine when you have the most energy. Do you struggle to get out of the bed in the morning or do you wake up full of energy and ready to go?    2     Once you establish what your sleep tendencies are, you will have a better idea of when your body is most likely to exercise. If you are not a morning person, do not schedule early morning exercise.

    3     When are you the busiest? When do you tend to schedule your most important tasks? Try to fit in your exercise before or at least around these events if possible. Some people would prefer to put it first while others prefer to put it off until the end of the day when they are all caught up.

You should determine your exercise goals. Are you trying to lose weight? Are you trying to improve your performance? Are you trying to develop a consistent exercise routine? If you are trying to develop a routine, you may want to exercise in the morning. If you want to improve performance, afternoon or evening exercise may be best.    4     Start by working out at different times of the day. By doing that you can know how you feel and find the time that works best with your schedule.    5    

6 . There's more evidence that what's good for your heart is good for your head. A new study shows that people who run, swim or do other moderate intensity （中等强度）exercise have brains that look, on average, 10 years younger than the brains of couch potatoes.

“Our study showed that for older people, getting moderate intensity exercise may be protective, helping them keep their brains work better," said Dr. Clinton Wright of the University of Miami, who led the study. But it's not necessarily easy. Walking, golf, bowling and yoga don't count, and people need to start before they begin showing memory loss, Wright' s team reported in the journal Neurology.

The study of nearly 900 people who exercise regularly showed that 90 percent fell into the low-intensity group. These people are part of a larger group taking part in a bigger study called Northern Manhattan Study. They were asked how long and how often they exercised during the past two weeks. Five years later, they were tested for memory and thinking skills and got a brain MRI. Seven years after that, they took the memory and thinking tests again. The 10 percent who said they took part in moderate intensity exercise scored better on the tests. These included running, climbing, swimming, riding bicycles and so on.

“We found that those with moderate intensity activity had higher scores and slower decline than inactive people when comparing the results," the study team wrote.

Many studies have shown that exercise may not prevent Alzheimer's disease but may delay it. The findings fit in with a study that found two years of exercising, eating healthier food and brain training can promote people's memory function.

7 . These days, football is one of the most popular sports in the world.    1     It was then known as cuju, a game using a ball of animal skins with hair inside. Football as we know it today started in Great Britain, where the game was given new rules.

The basis of the popularity of football may be that it is such a simple game to play.     2     You don’t need expensive equipment; even the ball doesn’t have to cost much money. All over the world you can see kids playing to their hearts’ content with a ball made of plastic bags; just like Pele did when he was a boy.

    3     It is fun enough to attract millions of people. You do not have to be a fan to recognize the skill of professional players or to feel the excitement of a game ending with a surprising twist.

What’ more, football has become one of the best ways for people to communicate: it does not require words, but everyone understands it.    4     Take, for example, the famous football game on Christmas Day 1914. World War I had broken out months before, but British and German soldiers put down their guns and played football together—one moment of peace to remember during years of conflict.

    5     However, in the eyes of Bill Shankly, the famous footballer and manager, it is   much more important than that. This might sound funny, but one only has to think about the Earth to realise that our planet is shaped like a football.

8 . What: The 2019 World Championships

Why You Should Watch: It’s the best track field competition the world has to offer outside of the Olympic Games.

When: Races and field events begin on September 27 and run through October 6.

Where: On October 3, NBC Sports Network will continuously air the meet from 9:15 a. m. to 5:30 p. m. EST. All day, you can also stream (流播) every event on NBC Sports Gold(Requires: $59.99). Clicking, you can find the full broadcast plan here.

This year it’s the first time a Middle Eastern city has hosted the event. It also might be one of the hottest world championships. To reduce the possibility of heat stroke or tiredness, all of the events start after 4 p. m. Doha time (9 a. m. EST), with some events much later—including the marathon, which kicks off at midnight on September 27.

To help cool athletes and audiences, air conditioning units have been set inside the stadium. Athletes competing in events 1,500 meters and longer will also be asked to take a pill that tracks their temperatures, with the hope that this data can help prepare race organizers, athletes, and coaches for the hot conditions expected at the 2020 Tokyo Olympics.

Temperature aside, there are some fiery races to look forward to this year, minus a few noteworthy names: six-time world champion Mo Farah of Great Britain, and two-time Olympic 800 gold medalist Caster Semenya of South Africa will not be competing.

Races to Watch on Day 7:

● The fastest time in the first round belongs to 10,000-meter champ Sifan Hassan. The race is at 4 p.m. EST.

● The men’s heats of the 1, 500 will include Craig Engels, Ben Blankenship, and 2016 Olympic gold medalist Matthew Centrowitz. The races start at 3 p.m.

● The finals of the women’s 400 meters includes Americans Adeline Jonathas and Phyllis Francis. The race is at 4:50 p.m.

9 . The Winter Olympics is also called the White Olympics. At this time, many colorful stamps are published to mark the great Games. The first stamps marking the opening came out on January 25, 1932 in the United States for the 3rd White Olympics. From then on, publishing stamps during the White Olympics became a rule. During the 4th Winter Olympic Games a group of stamps were published in Germany in November 1936. The five rings of Olympics were drawn on the front of the sportswear. It was the first time that the rings appeared on the stamps of the White Olympics. In the 1950’s, the stamps of this kind became more colorful.

When the White Olympics came, the host countries (东道国) as well as the non-host countries published stamps to mark those Games. China also published four stamps in February 1980, when the Chinese sports men began to take part in the White Olympics. Japan is the only Asian country that has ever held the White Olympics. Altogether 14,500 million stamps were sold to raise money for this sports meet. Different kinds of sports were drawn on these small stamps. People can enjoy the beauty of the wonderful movements of some sportsmen.
