Abstract

The body is always under attack by viruses, bacteria and parasites. One of the new viruses is the emergence of Corona. Along the way, the body has always evolved its own systems to deal with all kinds of viruses and developed sophisticated mechanisms to defend against these invading agents. based on the consensus of the researchers, it can be concluded that exercising up to a maximum of 50 to 75% maximum and up to a maximum of 45 to 60 minutes per day can have positive effects on immune function. Because exercise improves cardiovascular health by maintaining and improving immune function indices to some extent (9 and 3), and suggests that in addition to maintaining and improving the immune system in response to coronary artery disease, it can be effective. It can be pointed to the proper effect of physical activity on depression, anxiety, self-esteem, general health, quality of life, lifestyle and other mental and psychological parameters. Finally, it was suggested as an effective strategy for physical activity to moderate intensity (9). It can also help maintain and improve the immune system if you work out at high intensity if resting and proper nutrition between exercise sessions (10). Following, as recommendations for staying home to prevent the onset of Coronvirusa Disease have been made available to different segments of the community, As a solution, moderate to home exercises can be done to maintain and improve physical fitness, as well as to improve immune system and mental health.
