According to the CSSE Johns Hopkins Daily COVID-19 Report, as of the 18th, there were 614,183,335 confirmed cases of COVID-19 worldwide and 6,537,100 deaths.
According to a trend report released by the World Health Organization (WHO), the number of deaths related to COVID-19 worldwide from the 5th to the 11th of this month decreased by 22% compared to the previous week, and the number of new confirmed deaths fell. cases also fell by 28%, marking the end of the epidemic. However, there is a possibility of a resurrection, so the tension should never be relaxed.
Under these circumstances, Japanese health information media ‘Medical DOC’ reported on the 19th that physical activity for 150 minutes a week can reduce the severity of the new coronavirus and reduce the risk of death.
According to the report, a research team at the University of Valencia in Spain conducted a meta-analysis on the relationship between physical activity and novel coronavirus infection, severity, hospitalization, and death, and the risk of death associated with it was reduced . 43%.
The study was conducted on 1,853,610 cases, with an average age of 53.2 years, of which 53% were women.
In the paper published by the researchers, further studies need to be carried out using standardized assessments of physical activity, but 150 minutes of moderate to high physical activity per week or 75 minutes of high intensity physical activity per week became guidelines for the study . .
Moderate exercise is known to increase immune-related white blood cell function and reduce levels of inflammation and oxidative stress.
Experts believe that exercise improves cardiorespiratory function, muscle strength, and muscle quality, as shown in the results of this study.
“The causal relationship between physical activity and the infection and severity of coronavirus is not known, but it is an important study that shows the importance of moving the body often,” said Hidetaka Hinataka, a general internal medicine specialist in Japan.
He said that if you gain weight or weaken muscles due to a reduction in physical activity, lifestyle-related diseases such as diabetes and high blood pressure will worsen, increasing your risk of contracting various infectious diseases, include coronavirus.
Then, he stressed, “Moving the body without losing to the virus, that is, moderate exercise, is like ‘medicine without any side effects’.”
