It is well known that moderate exercise is good for health, but a new study of more than 1.8 million people confirmed that exercise was effective in preventing infection with COVID-19, significantly reducing the risk of aggravation, including the risk of hospitalization and death.
Research shows that basic diseases such as obesity and lifestyle-related diseases increase the severity of COVID-19, and improving these risk factors through exercise is expected to have an effect on the risk of COVID-19. However, although there are few studies systematically examining the relationship between habitual physical activity and COVID-19, there is a problem in that the number of samples is small and subject bias.
Therefore, a research team from the University of Valencia in Spain conducted a study to analyze the research on exercise and the risk of Corona 19 by systematic review and meta-analysis. The research team first searched reviewed studies on COVID-19 in three major thesis databases and removed those that had different topics or did not meet the criteria. In addition, 16 cases were selected out of 291 documents found, and data were extracted and analyzed.
The study included data from a total of 1,853,610 adults, of which 54% were women, with an average age of 53 years. In addition to Korea, the study was conducted in the UK, Iran, Canada, the UK, Spain, Brazil, Palestine, South Africa, and Sweden.
According to the analysis, people who engage in regular physical activity on a daily basis have an 11% lower risk of contracting COVID-19. Moreover, it was found that those who exercise had a 39% lower risk of hospitalization, a 44% lower risk of aggravation, and a 43% lower risk of death than those who lack exercise.
It is pointed out that the exercise effect is maximized where the MET based on the amount of exercise is 500 per week. If you convert 500 MET a week into exercise, it is said that 150 minutes of moderate-intensity exercise per week and 75 minutes of high-intensity exercise are equivalent.
Specifically, according to the exercise examples told by the Harvard Graduate School of Public Health, moderate-intensity exercise is very fast walking or light exercise using a bicycle, tennis and boxing. In addition, high-intensity exercise includes jogging, hiking, biking at high speed, soccer matches, and tennis.
Next, if you calculate with the MET calculation tool, for example, if you walk in 130 minutes, if you run in 50 minutes, you get 500 MET. If you do this kind of exercise for a week, it can be said that the effect against COVID-19 is maximized.
The research team said that it is necessary to pay attention to the possibility that the study design is different for each literature using the data, and the study target is beta or delta COVID-19 rather than omicron, which may aggravate the results of this analysis. On the other hand, he pointed out that moderate and regular exercise may increase the anti-inflammatory response, cardiorespiratory function, and muscle strength, which may explain the efficacy of COVID-19.
