The Effect of Exercise Intervention on the Immune System in COVID-19

Today, COVID-19 has spread rapidly around the world since its origin in Wuhan, China.COVID-19 is a beta-cornea virus-coated RNA known as acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Common symptoms of COVID-2019 are fever and cough. This study was performed to show the effect of exercise intensity on immune system changes during the occurrence of Covid 19 infection.

Methods and Materials: 

This review article has been performed on the effects of exercise on immune function and strength in covid-19 in various databases such as web of Science, Scopus, EBSCO, Medline, Google Scholar, PubMed and reviewed clinical trials and systematic studies.

It was shown that physical activity specially regular and moderate intensity aerobic exercise (VO2 MAX 80% 65-65) increases antibody titer, lymphocyte proliferation, interferongamma production, cells NK, M and G immunoglobulin’s as well as modulating the levels of inflammatory cytokines and chemokines.Therefore, it can be assumed that exercise is an important tool for shortening the recovery period and causing complications due to its antiinflammatory and strengthening effects on the immune system.

Based on indirect evidence and a conservative approach, high-intensity exercise may be dangerous (especially in obesity), possibly due to oxidant production and suppression of the immune system, and it may help exacerbate the COVID-19 virus. Based on the evidence, intense exercise in the immune system shows a conservative approach. Moderate-intensity exercise (rather than high-intensity physical activity) can be recommended as a non-pharmacological, inexpensive, and effective way to combat the COVID-19 virus.
