Exercise Against SARS-CoV-2 (COVID-19): Does Workout Intensity Matter? (A Mini Review of Some Indirect Evidence Related to Obesity)

SARS-CoV-2 (COVID-19) is a new virus causing respiratory illness outbreak. Nowadays, COVID-19 has spread to several countries around the world and is presently a major global concern. It appears that no certain effective pharmaceutical agent is currently available for it. It seems that obesity is one of the biggest risk factors related to COVID-19 hospitalization and critical illness. The strengthening of the body systems by non-drug ways is very important especially in obese people. On the basis of some indirect evidence, it seems that moderate physical activity can be recommended as a non-pharmacological, inexpensive, and viable way to cope with corona. On the other hand, recommending higher intensity exercise needs further consideration to make final decision in this regard.

Keywords: High-intensity exercise; SARS- CoV-2 (COVID-19); moderate-intensity exercise; obesity.

The 'open window' theory. It is characterized by suppression of the immune system following the intense exercise.

"J curve" concept. It suggests that, individuals that regularly perform moderate intensity exercise improve their immune system. Excessive bouts of prolonged training can impair immune function.
