Cycling and Jogging Can Cause Coronavirus Infection?. Recently, an article on the topic should not walk, run or bike near others during the Covid-19 season has caused public confusion, causing many people to worry.
In early April, an article posted on the Medium blog platform suggested that there was a risk of infection with the SARS-CoV-2 virus from running or exercising.
“Why can’t you walk, run or bike near others during the Covid-19 season?”.A blog post by entrepreneur Jurgen Thoelen led the research by a professor at Eindhoven Technical University. Assuming that water droplets from a previous person may hit the pedestrian behind at a distance of 4-5 m. If riding a bicycle, the distance up to 10-20 m.
“In many countries, walking, running or cycling is an acceptable activity during the Covid-19 season. However, you need to pay attention to distance from drops from others when exercising,” the article said.
Mr. Thoelen’s post got a lot of attention and shared. Shortly thereafter, the online community and the author himself quickly pointed out the flaws of this article.
Haven’t finished research yet hurriedly brought up the media
Mr. Bert Blocken, who carried out the initial research, immediately corrected his purpose. He explained that he had not finished his research and publication, but only talked to a Belgian newspaper on the subject.
What Mr. Blocken, an expert working at Eindhoven Technical University, analyzes purely based on aerodynamic aspects. From the phenomenon of airflow behind a moving object (slipstream), Mr. Blocken simulates the distance that the water droplets from runners, cyclists in front can shoot backwards.
Although the study suggests that people need to ride bikes at least 10 meters apart, the distance is too big for cities, Mr. Blocken said that his ideas were misinterpreted.
“I have never advised people not to walk, run or exercise, but vice versa. Perhaps people should read more and react less,” Blocken wrote in an email to Vice.
However, the incomplete research that has put information into the media is the opposite of the normal process. Vice said his research has not been published yet so there is nothing to read. Even Mr. Blocken’s motive for sharing information is suspected.
“The crisis is very serious, so we decided to go against the normal process. The publication of research cannot wait for months for the control review process. I have a brief piece of information and will post to LinkedIn, “Mr. Blocken wrote on Twitter. However, the information he posted on LinkedIn was only a translation of the Belgian article.
“It must be said that this is a study of aerodynamics, not virology. The publication of information in technical journals takes a long time to control, and Covid-19 cannot wait for months,” said Blocken. added in an email to Vice .
No epidemiological value
Given that Mr. Blocken’s “contribution” could be harmful to the community, epidemiologist William Hanage, who works at Harvard’s Center for Infectious Kinetics, said the study was invalid. Mr. Hanage even argued that the defense was an “anti-epidemic” contribution that “boiled blood” to him.
“Research like this has no effect on epidemiologists. The number of cases spread in this form is much less than in other cases,” Hanage explained.
“From an epidemiological perspective, the location of the droplet is less important than number of droplets through this method,” Mr. Hanage added. Neither the Belgian original article nor the Medium article took any account of the number of drops.
In the notes of the text, Mr. Blocken acknowledges that danger from microscopic droplets remains a subject of debate among researchers. On the Atlantic, interviews with some epidemiologists show that there is no unified conclusions about the spread of SARS-CoV-2 virus during exercise such as jogging, cycling.
However, the World Health Organization (WHO) and local epidemic prevention agencies have recommendations for exercising and exercising to stay healthy. The recommended safe distance from contact with others is 2 m.
Speaking to Vice , Mr. Hanage said that it is still possible to exercise outside, as long as there are appropriate measures.
“I think there is a balance, just avoid the circumstances where the infection rate from the community is high,” Mr. Hanage said.

If you cannot make out whether there is a dog in front of you or a pig, and stones seem to be speaking, then do not rush to think that something is wrong with you. Perhaps it’s all about a distorted perspective or a particular position from which you view the subject.
We have some photos that could have been completely banal, but thanks to the camera angle, they seriously hooked Internet users.
