It turns out that regular exercise reduces the risk of death from the new corona by 43%, how much should you exercise?

It's well known that a moderate exercise routine is good for your health, but a new study of more than 1.8 million people finds that exercise can help prevent COVID-19 infection and reduce hospitalizations. It has been confirmed that it is effective in greatly reducing the risk of aggravation, including the risk of death and death.

Physical activity and risk of infection, severity and mortality of COVID-19: a systematic review and non-linear dose–response meta-analysis of data from 1 853 610 adults | British Journal of Sports Medicine

Regular physical activity linked to lower risk of COVID-19 infection and severity

Studies to date have shown that underlying diseases such as obesity and other lifestyle-related diseases increase the severity of COVID-19, and improving these risk factors through exercise reduces the risk of COVID-19. is also expected to be effective. However, few studies have systematically investigated the relationship between habitual physical activity and COVID-19, and even if there were, there were problems with small sample sizes and subject bias.

Therefore, a research team led by Yasmin Ezzatvar and colleagues at the University of Valencia, Spain, conducted a study to analyze previous research on exercise and the risk of COVID-19 through a

systematic review and meta-analysis .

The research team first searched for peer-reviewed studies on COVID-19 from three major publication databases, excluding those with different themes and those that did not meet the criteria. Then, we selected 16 of the 291 documents found, extracted the data, and performed the analysis.

The study included data on a total of 1,853,610 adults, 54% of whom were female, with an average age of 53 years. In addition, the areas where the research was conducted were South Korea, the United Kingdom, Iran, Canada, the United Kingdom, Spain, Brazil, Palestine, South Africa, and Sweden.

The analysis found that people who engage in regular physical activity on a daily basis have an 11% lower risk of contracting the novel coronavirus (SARS-CoV-2). In addition, it was found that those who exercised had a 39% lower risk of hospitalization, a 44% lower risk of severe disease, and a 43% lower risk of death from COVID-19 than those who did not exercise enough.

Below is a graph showing the relative risk of death from COVID-19 on the vertical axis and the amount of exercise on the horizontal axis. The research team points out that the graph flattens out when the MET , which is the standard of exercise, reaches 500 per week, and the effect of exercise is maximized here. In addition, when converting 500 METs per week into exercise, it is equivalent to 150 minutes of medium-intensity exercise and 75 minutes of high-intensity exercise per week.

Find out what kind of exercise you need. First, according to

examples of exercise given by the Harvard School of Public Health, 'moderate-intensity' exercise includes walking very fast, light exercise on a bicycle, and doubles tennis. “High-intensity” activities include jogging, hiking, fast biking, playing soccer, and playing singles tennis.

Next, if you calculate with the MET calculator , for example, you can reach 500 METs in about 130 minutes of walking or about 50 minutes of running. is.

The research team used different research designs for each document used as data, and the research target was beta and delta strains of SARS-CoV-2, not Omicron strains, which weakens the results of this analysis. I have to be careful with the possibilities.

On the other hand, he pointed out that moderate and regular exercise enhances anti-inflammatory responses, cardiopulmonary function, and muscle strength, which may explain its efficacy against COVID-19. highlights that adequate physical activity has protective effects that reduce the risk of severe COVID-19.'
