In Norway, athletes avoid the virus retreating and becoming infected

Like many countries, Norway ordered the closure of all stadiums in March to prevent the spread of coronavirus. But unlike any other country, Norway has funded a rigorous study to determine whether the shutdown is really necessary.

Obviously, this is the first and only randomized trial to test whether people who exercise in the gym are at higher risk of coronavirus infection than those who are not restricted. Tentative answer after two weeks: No.

Therefore, this week, Norway responded to the research it funded and reopened all of its stadiums and adopted the same protective measures as in the study.

Is there hope for gymnasts in other parts of the world?

Dr. Michael Bretthauer, a cancer screening expert at the University of Oslo, said: “I personally think this can be generalized, but there is one thing to pay attention to.” Dr. Mette Kalager led the study. “In some places, there may be a lot of Covid, or people are not willing to comply with the restrictions.”

Norway is controlling its epidemic, and the number of new infections has declined. But the infection rate in Oslo, where the study was conducted, is similar to Boston, Oklahoma City and Trenton, New Jersey.

The trial began on May 22 and includes 5 gyms in Oslo. There are 3,764 members between the ages of 18 and 64 who have no potential medical conditions. Half of the members (1,896 people) were invited to return to their gym to exercise.

They are required to wash their hands and maintain a social distance: three feet for floor exercise and six feet for high-intensity classes. Subjects can use lockers, but not saunas or showers. They were not required to wear masks.

There are also 1868 gymnasium members as a comparison group. They were banned from returning to the stadium.

In the two weeks of the study, 79.5% of the members invited to use the gym participated at least once, while 38.4% of the members participated more than six times. Some people are overjoyed to restart their routine work.

The 53-year-old economist Goril Bjerkan lives in Baerum on the outskirts of Oslo. During the study, he ran three to four times a week, used a treadmill, took classes and conducted Strength Training.

She said: “It’s great to go back to the gym again after nearly 11 weeks of suspension.” “I doubt going to the mall is more risky than going to the gym.”

57-year-old architect Heide Tjom rode into Oslo by bicycle. She had the opportunity to return to the gym four times a week, where she worked with personal trainers and participated in aerobic classes.

Ms. Jom said: “Maintaining health is very important to me.” “I think this is important to my existence.”

During the study period, Oslo had 207 new coronavirus cases. The study participants and gym staff performed an infection check on June 8. (The participants are currently being tested for antibodies.)

Dr. Bretthauer and Dr. Kalager also checked Norwegian’s extensive electronic health record database to understand participants’ outpatient and hospital conditions.

result? The researchers found only one case of coronavirus. This person had not used the gym before being tested. Back to his workplace. Some participants visited the hospital, but suffered from other diseases in addition to the coronavirus Covid-19.

There was no difference in hospital visits between the two groups, and there was no outpatient visit or hospitalization due to coronavirus. The survey results were published online on Thursday, but have not yet been peer-reviewed or published.

Some experts believe that the results indicate that it is relatively safe to return to the gymnasium-but only in places with few infections.

    • Is it harder to exercise while wearing a mask?

      A comment published on the British Journal of Sports Medicine this month stated that covering the face during exercise “has potential breathing restriction and discomfort problems” and requires “a balance of benefits and possible adverse events.” Cedric X. Bryant, chairman and chief scientific officer of the American non-profit organization Sports Commission, said that masks will indeed change sports. The committee is a non-profit organization that funds sports research and provides certification for fitness professionals. He said: “In my personal experience, wearing a mask at the same relative intensity will have a higher heart rate.” Ren Krawitz, a professor of sports science at the University of New Mexico, said that some people also wear masks for familiar exercises. Feeling dizzy.

    • I have heard of a therapy called dexamethasone. Does it work?

      British scientists claim that steroid dexamethasone is the first treatment to reduce the mortality of critically ill patients. The drug seems to reduce inflammation caused by the immune system and protect tissues. In this study, dexamethasone reduced the death of patients using a ventilator by one third, and the death of patients using oxygen by one fifth.

    • What is the popular paid vacation?

      The Corona Virus Emergency Relief Program provides many American workers with paid leave if they need to take time off due to the virus. If you are sick, quarantined, being diagnosed or preventively caring for coronavirus, or caring for a sick family member, you can provide qualified workers with two weeks of paid sick leave. It gives 12 weeks of paid leave to people who care for children who are closed to schools due to coronavirus or have insufficient childcare services. This is the first time the United States has received extensive federal government paid leave, which includes people who usually do not have such benefits, such as part-time and gig economy workers. But this measure does not include at least half of the private sector workers, including those of the country’s largest employers, and gives small employers plenty of leeway to refuse vacations.

    • Has asymptomatic transmission of Covid-19 occurred?

      So far, the evidence seems to indicate that this is indeed the case. A widely cited paper published in April showed that people are most infectious two days before the onset of coronavirus symptoms. It is estimated that 44% of new infections are the result of transmission by people who have not yet developed symptoms. Recently, a senior expert from the World Health Organization said that it is “very rare” for people with no symptoms to transmit coronavirus, but she later dropped this claim.

    • What is the risk of catching coronavirus from the surface?

      Contacting contaminated objects and then infecting yourself with bacteria is usually not the way to spread the virus. But this may happen. Many studies on influenza, rhinovirus, coronavirus and other microorganisms have shown that respiratory diseases, including new coronavirus, can be spread by contact with contaminated surfaces, especially in day care centers, offices and hospitals. However, for diseases to spread in this way, a series of events must be carried out. The best way to protect yourself from coronavirus infections (whether it is surface spread or close contact with people) is still away from socializing, washing hands, not touching the face and wearing a mask.

    • How does blood type affect coronavirus?

      A European scientist’s study proved for the first time that there is a strong statistical link between genetic variation and the disease caused by coronavirus Covid-19. This new study shows that having type A blood increases the likelihood that patients need oxygen or use a ventilator by 50%.

    • How many people are unemployed in the United States due to coronavirus?

      The Ministry of Labor said on June 5 that the unemployment rate fell to 13.3% in May, which was an unexpected improvement in the country’s job market, because the number of recruiters is picking up faster than economists expected. Economists had predicted that the unemployment rate would increase to 20% after reaching 14.7% in April, the highest level since the government began retaining official statistics since the Second World War. However, the unemployment rate has fallen, and after losing more than 20 million jobs in April, employers have added 2.5 million jobs.

    • What are the symptoms of coronavirus?

      Common symptoms include fever, dry cough, fatigue and difficulty breathing or shortness of breath. Some of these symptoms overlap with the flu and are therefore difficult to detect, but runny nose and sinus stuffiness are less common. C.D.C. also increased chills, muscle pain, sore throat, headache and new loss of taste or smell, these symptoms deserve attention. Most people will get sick five to seven days after exposure, but symptoms may appear in just two days or up to fourteen days.

    • How to protect yourself in flight?

      If you cannot avoid traveling by plane, you can take some measures to protect yourself. The most important thing: wash your hands often and stop touching your face. If possible, choose a window seat. A study by Emory University found that during the flu season, the safest place to sit on an airplane is by the window because people sitting in the window seat have less contact with potential sick people. Disinfect hard surfaces. After arriving at the seat and cleaning your hands, use disinfectant wipes to clean the hard surfaces of the seat, such as the head and armrests, seat belt buckle, remote control, screen, seat back pocket and tray table. If the seat is hard and non-porous, leather or wrinkled, you can also wipe it clean. (Using a rag on an upholstered seat may cause the seat to get wet and spread bacteria instead of killing bacteria.)

    • What if I feel sick?

      If you have been exposed to coronavirus or think you have a fever or cough or difficulty breathing, call your doctor. They should provide advice on whether they should be tested, how to test them, and how to seek treatment without infecting or exposing others.

Dr. Gordon Guyatt, a medical professor at McMaster University in Canada, said: “This shows that a low-prevalence environment is safe for gyms and everything else.” “You are highly unlikely to be infected.”

He added: “If the prevalence of your environment is much higher, we don’t know what will happen.”

But Jon Zelner, an epidemiologist at the University of Michigan, does not think the study is persuasive: “These findings do not tell me that even in Oslo, going to the gym is riskier than not going to the gym. , ” He says.

Dr. Zellner added that a larger study is needed in places with a relatively low prevalence to determine whether the virus is more likely to spread in gyms. In addition, a small number of people in a study can answer this question in a community with a high infection rate.

Dr. Zellner said such research may raise moral concerns because it may not be safe to send people to gyms in highly prevalent communities-“a little Catch-22.”

How low is the risk of reopening the gym and fitness center?

Dr. Gayat said that among the prevalence of society, in a community with a low prevalence, the risk of infection exceeds the risk.

He said: “You can’t stay locked forever.” “We will never get rid of this completely. In a low-prevalence environment, no matter where you are, whether it is a gym, grocery store, or even a restaurant, the risks are all Lower.”

Now, Dr. Brettauer and Dr. Kalager want to see if the social isolation measures they used in the study are necessary.

They hope to randomly assign 150 gyms to allow them to operate unrestricted or maintain them in place now, and then compare the infection rates among sports fans. The study is only in the planning stage.
