On December 14, 2022, researchers at Kaiser Permanente Medical Center in Southern California published a paper titled "Associations of Physical Inactivity and COVID-19 Outcomes Among Subgroups" in the American Journal of Preventive Medicine. The study showed that exercise is the best medicine for COVID-19 . The more exercise, the lower the risk of severe illness, hospitalization, and death from COVID-19.
Researchers analyzed 194,191 adults infected with COVID-19 at Kaiser Medical Center in Southern California who were diagnosed with COVID-19 between January 1, 2020, and May 31, 2021. Positive, 15% of the infected people did not exercise, 43.0% of the infected people exercised for 0-60 minutes per week, 21.9% exercised for 60-150 minutes per week, 14.3% exercised for 150-300 minutes per week, and 5.8% exercised for more than 300 minutes per week.
Compared with infected people who exercise the most, those who do not exercise have a 191% higher risk of hospitalization and a 391% higher risk of death, those who exercise 0-60 minutes a week have a 143% higher risk of hospitalization and a 192% higher risk of death, and those who exercise 60-150 minutes a week have a 125% higher risk of hospitalization and a 155% higher risk of death.
Simply put, the more you move, the lower your risk of severe illness, hospitalization, and death from COVID-19 . Rates of adverse outcomes were higher among infected people who were less active, and those who were inactive had the highest rates of hospitalization, deterioration, or death. Although there are large differences in infection rates and outcomes among different groups, the campaign is always beneficial.
However, for friends who have recovered, it is not recommended to engage in strenuous exercise immediately. This is because the immune system has just fought a battle. At this time, the body is still relatively weak and the muscle strength has also declined. A healthy and nutritious diet and sufficient rest are needed for recovery. Excessive training load can easily lead to the body being in a window period, which is not only detrimental to recovery, but also makes it easier for to be infected again.
Infection with viruses usually causes myocarditis, whether it is the common cold virus (adenovirus) or the new coronavirus COVID-19. Myocarditis may also occur as a result of a reaction to medications or systemic inflammation. Signs and symptoms of myocarditis include chest pain, fatigue, shortness of breath, and a fast or abnormal heartbeat. Severe myocarditis can weaken the heart and prevent other parts of the body from getting enough blood. It can even cause blood clots to form in the heart, causing stroke or heart attack, and the consequences are still very serious.
Mild myocarditis has a high probability of being cured by itself or treated with medication. Under mild symptoms, it is recommended to suspend competitive sports for 3 to 6 months to avoid worsening of myocarditis; however, if the symptoms are more severe, a doctor may prescribe medication or other treatments.
Summary: Before recovery, it is recommended that everyone maintain moderate exercise habits and ensure at least 150 minutes of moderate to high-intensity exercise per week to reduce the risk of severe illness, hospitalization and death; after recovery, it is recommended that everyone not exercise strenuously immediately, pay attention to nutrition and rest, and gradually resume exercise habits to prevent myocarditis.
