The results showed that none of them in the control group was positive for covid-19.
The fitness group can freely go to the designated gym for fitness, but it must strictly abide by the epidemic prevention regulations, such as disinfection of fitness equipment immediately after use, and participants in high-intensity aerobic sports must keep a distance of more than 2 meters; The control group was not allowed to go to the gym, but everything else was the same.
The study was published in the August 2020 issue of emerging infectious disease.
“Descendants of the sun” stills this study was published on the website of unpublished paper preprints.
This result shows that the transmission efficiency of the virus is closely related to the fitness program, and the confined space may not be infected.
However, there is also a noteworthy detail in this study, that is, two fitness coaches infected by the virus have taken fitness classes with similar numbers in the same gym, and one coach has taken high-intensity dance classes, resulting in many students being infected; Another instructor took a low-intensity Pilates and yoga class.
At that time, the 27 people were asymptomatic, but eight of them were tested positive for covid-19, which should have been infected during the training.
Numerous evidences show that strength training is even more beneficial to the body than aerobic exercises such as walking, running, swimming and cycling, but their role is seriously underestimated in China.
All issues related to public epidemic prevention policies should adopt such epidemiological investigation methods and conduct comparative studies in real life.
The authors concluded that confined spaces such as gymnasiums are very easy to spread viruses, so they should be closed.
The problem is that the severity of the epidemic in Oslo is not enough, and only one new infected person was found in the end.
Two weeks later, the researchers tested the nucleic acid for these volunteers.
Welcome to forward it to the circle of friends,.
27 fitness instructors participated in the 4-hour high-intensity training.
As a result, none of her students were infected.
After the Oslo government read this paper, it really reopened the gym in the city.
Although there was one positive case in the fitness group, this person had not been to the gym in the past two weeks and should have been infected in other places.
Which of these two opinions is right? Let’s analyze it in detail.
The case of South Korea clearly shows how dangerous a confined space is, which is also the basis for the social distance policy widely adopted in epidemic prone areas.
The authors concluded that gyms did not increase the risk of infection among Oslo people and should be open.
Researchers recruited nearly 4000 volunteers at the peak of the epidemic in Oslo and randomly divided them into two groups.
However, in those two weeks, Oslo had new confirmed cases every day, with 24 new coronavirus positive patients added on the most day.
Therefore, the epidemic situation in Oslo at that time was much more serious than that in Beijing, Urumqi and Dalian.
To sum up, we can conclude that the probability of virus transmission in the gym is related to the severity of the local epidemic and the sports events in the gym, and the results are difficult to predict.
However, the population of Oslo is less than 700000, which is less than that of Beijing Tiantongyuan community where a confirmed case has just been found.
The data volume is too small, resulting in little practicability of the study.
The researchers tracked down a fitness dance instructor training class held in Cheonan City, South Korea, on February 15.
Those who say they can certainly cite a study conducted by the University of Oslo in Norway.
The side that said it could not open would cite a study from South Korea.

(yuan Yue) with the gradual alleviation of the domestic epidemic, when will the gym be opened? There are two completely different opinions on this issue, and there is corresponding research support behind each opinion.
The research method of Oslo samples is very good.
These 8 students took classes in their own gymnasiums without knowing, resulting in 112 students being infected.
However, not opening the gym for a long time will definitely have an impact on the physical health of ordinary people, because aerobic exercise can also be solved by yourself outdoors, and anaerobic strength training such as iron lifting can only be carried out in the gym.
