The study finds that medical associations in Europe and the United States advocate that disease symptoms (asymptomatic infection/mild infection/moderate infection/severe infection) should be used as the basis for risk stratification in the assessment of physical fitness assessment after COVID-19 infection, and the diagnostic process should be implemented to track the development trend of clinical prognosis and evaluate the signs of recovery. Screening diagnosis shows that athletes infected with COVID-19 have mild cardiopulmonary injury and few complications, and asymptomatic or mildly infected athletes can return to play without any additional screening diagnosis based on the isolation rest of 10 days, but athletes with moderate infection or severe infection need precise screening. In this regard, from the five aspects of clinical practice skills, artificial intelligence technology, epidemic prevention and treatment plan, monitoring physical condition and training immune mechanism, this work can provide the theoretical system construction and the choice of strategic means for the physical fitness assessment of Chinese athletes returning to play, and also provide reference suggestions for the construction of the physical fitness assessment and competitive training theory.
