High cardiorespiratory fitness induced by prior exercise training likely confers innate immune protection against SARS-CoV-2 by attenuating proinflammatory cytokine storms.

Maintain high cardiorespiratory fitness through regular moderate-to-vigorous aerobic exercise. While this may help mitigate severe inflammatory responses to respiratory viruses like SARS-CoV-2, it is not a substitute for standard preventive measures like vaccination and hygiene.

LimitedConditionalLOW confidence
Here, we consider whether high levels of cardiorespiratory fitness induced by prior exercise training may confer some innate immune protection against COVID-19 by attenuating the 'cytokine storm syndrome' often experienced by 'at risk' individuals.
