According to studies, people who live a lifestyle where they tend to walk around less or do less exercise, are more likely to be admitted into the hospital and, or die due to Covid.
A new study confirms that you might stand a reduced chance of having severe Covid and subsequent hospitalization. In the study over 50,000 participants from California who had Covid, the ones who exercised were not likely to be hospitalized or die from Covid.
The researchers gathered information before vaccines were available and they found that there is no way to replace immunization with exercise. They do however stand by the fact that if you exercise regularly it can prevent serious infections.
Aerobic fitness makes people catch a cold less, they also are not known to have viral infections and if they get infected they recover quickly. This is partly due to the fact that exercise has a boosting effect on the immune system. The body’s response with antibodies when vaccines are taken is also increased by fitness
Because very little is known about the virus, it is hard to say if in fact, exercise can confer some resistance to the virus. February’s edition of The International Journal of Obesity, findings of the severity of Covid-19 among those who could walk faster was much lower than those who couldn’t participate in physical fitness. Yet another study among European adults revealed that stronger grip strength which is an indicator for good muscular heath, gave lesser Covid hospitalizations, but these studies were more about muscular strength than about repetitive muscular processes.
The most recent study made by the British Journal of Sports Medicine, done by a team of researchers and doctors at the Kaiser Permanente Southern California, University of California, San Diego working with some other medical bodies made a comparison between the frequency of exercise and the frequency of hospitalization last year due to Covid.
In Kaiser Permanente health care among the “vital signs” in the hospital rounds are exercise. Doctors and nurses inquire about the frequency within the week a patient exercises and the time spent doing these exercises, this is then added to the patient’s history.
The exercise activity was separated into sexes and into levels of activity, most active being 150 minutes per week and least active being less than 10 mins per week.
Data about age, habits of smoking, weight, cancer history, diabetes mellitus, transplant of organs, problems related to the kidney, and other conditions that could lead to severe Covid were put together.
The results of the study showed that those who were the least active exercising less than 10 minutes a week were 2 times more likely to be in the hospital because of Covid and died 2.5 times more than those who were active.
Among all the known risk factors only old age and organ transplantation were more likely to cause hospitalization or death among those with Covid.
Being sedentary was the greatest risk factor” for severe illness, “unless someone was elderly or an organ recipient
says Dr. Robert Sallis, one of the family and sport medicine physicians at the hospital where the study was done.
He also made it known that other risk factors can be changed but exercise can make a difference.
The study proves that people who exercised often were at lower risk of being severely ill and not that it causes the risk of Covid to reduce. The study was not also centered on if exercise could reduce infection with the virus also.
Dr. Sallis continued that the association in the study was not by coincidence but was very strong and suggested a brisk walk of half an hour 5 times a week as a protective regimen against Covid-19.
For those awaiting the vaccine, he says about 5 walks within the week can be very beneficial and that this is not in any way a replacement for the vaccine but it can help lessen the risk of infection. Exercise will most likely be protective against new strains of the virus or any other virus.
