1 . Do you like to keep fit? We’re always told that regular exercise is good for our body and mind. More and more people are taking up activities that improve their fitness. But is there a risk that some of us might get obsessed (着迷的) and overdo it?
Well, for some people, fitness has become an obsession as they aim for perfection. And fitness trackers and apps can add to this addiction, especially if someone is driven by achievement and perfectionism. And sharing data on social media means exercising becomes public and competitive, which could cause problems in someone who is vulnerable (脆弱的). Experts say this can lead to a medical condition called orthorexia nervosa, or addiction to healthy eating and over-exercise. Untreated, it can lead to malnutrition and mental health problems.
Too much exercise can also take its toll on someone’s physical health as well. Symptoms of over-exercising include injuries such as a broken leg and a low immune system. So how much exercise is too much? Researches found the ideal pace to jog was about eight kilometers per hour-and that it was best to jog no more than three times a week or for 2.5 hours in total, showing that moderate jogging is possibly more beneficial than being inactive or undertaking strenuous (剧烈的) jogging.
If you’re more of a couch potato than a runner, this might sound like good news. But for amateur (业余的) athletes who can’t help but push their bodies to the limit, the advice from Martin Turner, a sports and exercise psychologist, is, “It’s all about letting go, not being obsessed, learning not to control everything, saying, ‘You don’t need to be perfect.’”

8 . Though the Tokyo Olympic Games drew to a close on August 8, 2021, the public is still watching the athletes. Their outfits and the technologies that helped them in the competition have aroused people’s interest.
Su Bingtian, the first Chinese sprinter to reach an Olympic 100m final, has ascribed his breakthrough to scientific training. “It takes Su 47 steps to run 100 meters. Each step counts,” Liang Dong, a member of Su’s training team, told Shenzhen Evening News. “Randy Huntington, Su’s American coach and a biomechanics expert in track and field, has collected a lot of data on outstanding sprinters and built a database. He put in all of Su’s data and got a near-optimal model. When Su is training, the team uses high-speed cameras to record his training and compares it with the model to find out his weaknesses.”
Technology has also brought a new boost to table tennis. On July 27, the semifinal match between China’s Sun Yingsha and Japan’s Mima Ito was in full swing at the Tokyo Metropolitan Gymnasium. You wouldn’t have guessed that besides players, referees and audiences, a powerful AI platform was monitoring the match.
Every serve, swing and movement of Mima Ito was captured by this AI cloud platform deployed in Tokyo. At an average speed of 100 Mbps, the data was transmitted to the technical team of the Zhejiang University Table Tennis Intelligent Big Data Analysis Platform,2,442 kilometers away from the Tokyo Metropolitan Gymnasium, according to The Paper.
The Tokyo Olympic Games have seen not only scientific support in training, but many high-end technologies in athletes’ devices. For example, the Kenya women’s volleyball team’s GPS devices fed data on each player’s strength, heart rate and so on to coaches, who used the information to prevent injury and personalize training plans for each individual, South China Morning Post reported.

9 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research,
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.
A.Race walkers are conditioned athletes |
B.Like running, race walking is physically demanding |
C.Having a medical checkup |
D.It does, however, have its won problem. |
E.It’s this strange form that makes race walking such an attractive activity. |
F.It’s less likely to cause knee injuries |

10 . Exercise for a Better Brain
Most of the time, your brain is the boss of your muscle—directing how you hit a ball, play the piano, or open a cereal box.
In a study, people who ran for 45 minutes three days a week boosted their levels of a brain-derived neurotrophic(神经营养的)factor, a chemical that acts like fertilizer for new brain cells.
Studies suggest that in younger adults, exercise can add to the overall number of cell in the hippocampus(海马体).
A.Again, a little goes a long way. |
B.Tips have been offered as to how to properly exercise. |
C.After four months of workouts, their scores improves on a memory test. |
D.Besides this, studies have also suggested that dying cells can be cleared with regular exercise. |
E.But when it comes to growing new brain cells, more and more researches show that when you exercise, your muscles take charge. |
F.Exercise also helps keep brain cells alive longer and replaces old cells with new ones. |
G.The more light activity study participants logged, the greater the overall size of their brains. |
