1 . The last attempt of Ken Campbell to run could date back to high school. When his wife, Susan, injured her foot, she needed support to rejoin her running group, so Campbell went along to keep her company in the recovery. “We were just walking at the beginning,” he says, “I was heavy, and weighed over 90kg.” But as the weeks and months passed, the weight fell away, Susan recovered and Campbell’s abilities grew. At the age of 63, he ran 50 km, and at 70, he completed a 100 km ultramarathon (超长距离马拉松赛跑).

So how does someone with no experience of running become an ultradistance runner in his 60s and 70s? Susan had run marathons (马拉松比赛) before her injury, but for Campbell, the turning point came when Susan’s Fleet Feet running group started training near their home.

Campbell went out to visit Susan’s group, and “the paths were a terrible mess. It had been raining, and I was slipping, sliding and falling. But I thought, well, I like this a lot.” What he liked above all was the feeling of “being wrapped by the path, being hugged by the closeness of the plants and the nearness of the river”.

Running the 100 km ultramarathon took Campbell 16 hours. When Campbell crossed the finish line, Susan handed him a 100 km sticker to display on the back of his truck. “It is a public statement that you are part of this community,” he says. “Wherever we park, I see a line of vehicles with their various stickers and I feel that we are a community.”

Campbell suffered from arthritis before he started running, and was “waiting for knee replacement”, but for now, he no longer needs an operation. It can put an end to the running—but the “sense of wellbeing and achievement will carry me on forever,” he says, “If I can’t run, I will walk.”

2 . Teenagers have long been told that being active and taking part in various sports is good for their health. But new research suggests that too much sport for teenagers could negatively affect their well-being just as much as too little sport.

Researchers from Switzerland say their study suggests that 14 hours of physical activity a week is best for promoting good health in teenagers. However, they found that more than 14 hours appears to be detrimental to their health. To reach their findings, the researchers surveyed more than 1,245 teenagers aged between 16 and 20 from Switzerland.

All participants were required to answer questions on height and weight, sports practice, sports injuries and well-being. Their well-being was assessed (评估) using the World Health Organization (WHO) Well-Being Index, and the average well-being score for all participants was 17.

The researchers divided sports participation into low (0 — 3.5 hours a week), average (3.6 — 10.5 hours), high (10.6 — 17.5 hours), and very high (more than 17.5 hours). The researchers found that participants in the low and very high activity groups were more than twice as likely to have well-being scores below 13, compared with participants in the average group. The researchers   found that the highest well-being scores were gotten by participants who carried cut around 14 hours of physical activity a week, but exercising beyond 14 hours resulted in lower well-being scores.

Commenting on their findings, the researchers say physical activity has been connected with positive emotional well-being, reduced sadness, anxiety and stress disorders, and improved self-respect in teenagers.

The researchers suggest that their study stresses the importance for physicians caring for teenagers to check their level of sports practice and ask them about their well-being. Teenagers probably need a supportive and closer follow-up of their health and well-being. The findings can provide information for guideline groups who produce recommendations on sports practice for teenagers.

3 . 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 (遗传的) 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.

5 . Most people in their eighties would consider themselves lucky not to have health problems, but this is not the case with Toshisuke Kanazawa. The 82-year-old Japanese bodybuilder is not only in perfect physical condition, but also looks better than a lot of men a quarter his age.

Kanazawa is a living example that you’re never too old to hit the gym and achieve the body you’ve always dreamed of. A champion bodybuilder in his youth, Kanazawa stopped exercising completely after he retired(退休) at age 34, drinking, smoking and eating whatever he liked. It wasn’t until he turned 50 that he wanted to regain the perfect body of his younger years.

Kanazawa’s wife felt sick frequently, and the former bodybuilder remembered that she had never been happier than when he won the national championship. So, to please her, he decided to return to the gym and completely change his diet.

His workout schedule had to change according to his age. In his youth, he would spend up to six hours training in the gym every day, and his body would recover within two days after a particularly intensive workout, but that was not the case anymore. He cut the daily gym time to three hours and started giving his body one week to recover after exercising every muscle group.

Kanazawa’s efforts paid off. In 2016, at the age of 80, Kanazawa defeated many opponents and placed sixth in the world in a match for bodybuilders over 65, and won the admiration of the crowd.

Sport keeps this elderly man healthy, as he has not suffered so much as a cold since he started bodybuilding again at age 50.

“I want to be a super old man in the bodybuilder community,” Kanazawa said, “If I have a goal, I can continue moving forward. I have to work much harder.”

6 . Walking has been considered as one of the best possible exercises. For many people, daily walking offers many and long-term physical and mental benefits.     1     A Stanford University study found that participants were more creative when walking as opposed to sitting.    2    You’ve probably heard the phrase “exercise your innovation (创新)”. Our creative mindset is caused by physical movement, which is exactly why walking with your dog, a friend, or alone feeds creative thinking.

But the scenery is almost as important as the sweat. Just by going outside, you are stepping out of your habitual surroundings and your comfort zone, which is necessary if you want to open your mind to new possibilities. You can walk through a tree-filled neighborhood.     3    

Walking outside develops our ability to collect new ideas and take in new sights, sounds, smells, and flavors. Shinrin-yoku, a common form of relaxation in Japan, suggests that being in the forest and walking among the trees there can lower your stress levels    4     Research has shown that immersion (沉浸) in nature around your neighborhood or the disconnection from multimedia increased performance on a creative problem-solving task.

So instead of setting a fitness goal, why not set a creativity goal that starts with walking outdoors?     5     For example, you can turn off your phone and give yourself the chance to be present in the world, to hear conversations and natural sounds, and to notice the way people move and the way the sun reflects in a lake.

Walk not just for exercise. Walk for wonder.

7 . In many parts of the world, there are four seasons: spring, summer, fall and winter. In the U. S., there are only three: football, basketball and baseball. If you want to know what season it is, just have a look at what people are playing.

For many people in the U. S., sports are not just for fun. They’re almost a religion. Thousands of sports fans buy expensive tickets to watch their favourite teams and athletes play in person. Other fans watch the games at home. The most devoted sports buffs never miss a game. Many a wife becomes a “sports widow (寡妇)” during her husband’s favorite season.

America’s devotion to athletics has created a new class of wealthy people: professional athletes. Sports stars often receive million-dollar salaries. Some even make big money appearing in advertisements for soft drinks, shoes and even toiletries (化妆品).

Sports are an important part of Americans’ culture. Throughout their school life, Americans learn to play many sports. All students take physical education classes in school. Some try out for the school teams, while others join school sports leagues. Athletic events at universities attract scores of fans and benefit the whole community.
